Swift Course 2024 : Ultimate Course For Beginners

1. Introduction To Swift Course: Welcome everyone to the complete SIFT programming beginner course. So this course consists of two different modules. In the first model, we are going to discuss about the concepts like how to run the Sift to program in Windows. Also, we are going to discuss about variables, data types, conditional statement, far loop, arrays in Sif programming language. In the second module, we are going to discuss about object oriented concepts class object, polymorphism, inheritance in SIFT programming language. So this course is very, very, very useful for the beginners who are trying to learn Sift programming language for the first time. So let's get started. 2. Swift Class 1 : Introduction To Swift: Welcome, everyone. In today's class, we are going to discuss about introduction to SIFT programming language. So SIFT is powerful modern programming language developed by Apple. So it is very, very useful for if you want to create any application for IOS or Mac, you have to use SIFT programming language. So that's the second point. It is designed to be fast safe and expressive, making it a popular choice for building IOS, MAC, and other Apple platform applications. If you want to create any applications for IOS how to use SIFT programming language. So it was developed by Apple. So it is the introduction to SIFT programming language. So after that, we are going to discuss about history and evaluation of CIF. So the SIFT was first introduced in the year 2014. So after the replacement for Apple object to C language. So it is an advanced version of CN language. And then second one is nothing but rapid adoption. So SIFT is very, very popular. It is very, very popular for creating the Mac and IOS applications. So the third one is nothing but continuous improvement. We know that the applications like IOS, mobile, and Mac Lab or desktop are updated every year. Then the language is also updated. That language is nothing but shift programming language. So after that, we are going to discuss about advantages of SIP. So the first one is the performance. So SIFT is powerful and fast programming language. So that's the first advantage, and then second advantage is safety. If we use SIP programming language, the source code are very safety than other programming languages. And then third advantage is nothing, but the SIFT will provide the source code both readable and maintainable. After that, we are going to discuss about the disadvantages of CIF. So the first tone is the cross platform support. So the SIFT program language is mainly developed for the apple applications like Mac and IOS. So that's the first disadvantage. And then second disadvantage is nothing so SIFT has low libraries compared to other programming languages like C and C plus plus and CSR. So that's the second disadvantage. And the third disadvantage is nothing, but the syntax of SIFT programming language is different than other programming language. So these are all the disadvantages. What are all the applications that can be created using SIFT programming language? So the first is the IOS and then second one is the MAC and then third one is the server side. You can use the SIFT for building the web services and APIs, then you can use SIFT programming language for missing learning and AI. So if you want to create any projects using missing learning and AI, you can use the SIFT programming language. So these are all the applications that can be created using SIFT. So the main one is the Apple applications, IOS and MAX. Atlas, we are going to discuss about the job opportunities when you learn SIFT programming language. So you can achieve the jobs like IOS developer, MacOS developer, server side developer, and ML engineer. When you learn SIFT programming language, you can achieve these jobs. So that's it, guys. In today's class, we are discussed about the introduction to SIFT programming language. So in the upcoming class, we are going to discuss about how to run the SIFT programming language in Windows. So let's see in the next class. 3. Swift Class 2 : Running Swift In Windows: Welcome everyone to the first class. In today's class, we are going to discuss about how to run SIFT program in Windows. SIFT can be run only in MacOS. If you want to run the SIF in Windows, you need to download the software. The software is nothing but SIFT for Windows. You have to select download Absen so you can see the download is started. So you have to wait for the download. So after the download is completed, you have to open the file and you have to select agree and then install. So you have to select Install option for installing the software for running the sift in Windows. So you have to wait for the installation, or after that, you have to select Finish. So this is the GOI for running the Sift in Windows. So you can see the two options compile and run. So if you want to compile the SIFT program, you can use that. Also, you can use Run. If you want to run the SIFT programs, you can use that option. Also, you can see the third option that is Select File. You have to select your CIF to five for running the output. So after that, you need to open your Windows C, and then you have to open the CIF Inside that, you have to open the bin folder. Inside the bin, you have to copy the file location. You have to copy the location, and then you have to open the properties, environment variables. You have to copy the path and paste that inside the environment variable. In two variables, user variables, and also system variables. Thenly the SIFT program will saw the output. So you have to open the command and then you have to type Sift hyphen hyphen verson. You can see the verson 4.1 0.3. So we have successfully installed Sift for our windows. Now we can run our SIFT program in Windows. For that, you need to create a folder, and then you have to open the folder with VS code. So after opening the VS code, you need to install some of the extension. For that, you have to open the extension. So in that you have to type sift. And then you need to install the extension. After installing the extension, you need to create new file for that you have to select new file, and then you have to type the name of the file. I'm going to type sample dot SIFT. So that's the extension for creating the SIP to file. So now we are going to discuss about how to run the file in the VS code. First, we are going to print the output for printing the output, you have to type print off inside that, you have to type the string. I'm going to type Halo world. So after that, you have to run the code. So you can see the output Hala world. So this is how you can run the SIFT program in the VS code. Also, you have to run the code using the SIFT for Windows. So you have to select your file, you have to select your file. And then you have to select compile. So you can see successfully compiled, and then you need to run the code. So you can see the output her world. So there are two ways for printing the output. You can select terminal of the VS code or Sift for Windows software. So it is your own choice. So that's it, guys. In today's class, we are discussed about how to run the SIFT program in Windows. 4. Swift Class 3 : Variables: Come, everyone to the second class. In today's class, we are going to discuss about variables in F. So a variable is nothing but a container, which is the data. So we are going to see an example how to create variables. For that, you need to type the keyword where. So you have to type where, and then you need to type the variable name. So you can type your own name equal to ten. So A is the variable, and ten is the value. Also, you can use the keyword let. There are two keywords you can use where and let. So if you want to print the variables, you have to type print off, and then variable name. So this is how you can print the variables. You have to run the code, you can see the output ten and 20. So if you want to clear the screen, you have to type CLS. Also, you can see the output in Sift for Windows, so you have to select the file, and then you have to compile the file, and then you have to run the file. So you can see the output ten and 20. So where is nothing but if you create where, it will be considered us global variable. But in let it will be considered as local variable. It cannot be redeclare, but where can we redeclare? 5. Swift Class 4 : Datatype: Come, everyone. In today's class, we are going to discuss about data types in SIP to programming language. So there are many data types like int, float, string, character, double. So in SIP programming language, the syntax is very different than other programming language. So for that, we are going to see an example. So first, you have to type the keyword that is where. So that's the keyword for creating the variable, and then you have to type the variable name, A, and then you have to type colon. So that's the syntax. And then you need to type the data type. So I will be capital Int. So we are going to create It data type variable. After that, you need to type equal to value. That is ten. So this is how you can create data type in Sift. So you have to type Int. That's the upper case. So we have just created int datatype. After that, we are going to create second data type, that is string as an capital, equal to quotation inside the Dot type string a world. So this is how you can create string data type. For swift programming language, you don't need to type semicolon to the statement. It will not consider that. So after that, we are going to create third data type, that is character data type. So you have to type full character, equal to single quotation. Inside that, we are going to type A. For character also, you need to type double quotation. So after that, we are going to create the fourth data type that is float. So you have to type F, colon float, you have to type float, equal to, you have to type the floating value 20.5. So it is considered as float data type. After that, we are going to create double. You have to type D, colon, double equal to 32.45 56. So it is considered as double. After that, we are going to discuss about the last data type that is boolean. So you have to type bool equal to true or false. So it is considered as Boolean data type. So if you want to print the variables, you have to type print off, and then variable name and then run the code, you can see the output ten. After that, I'm going to print string for that you need to change the variable to B and then run the code, you can see the output color world. And then I'm going to print Boolean, you have to type zt, and then print the output. You can see true. So this is how you can use data type in sift. So the syntax is very different than other programming language. 6. Swift Class 5 : Arithmetic Operator: Welcome, everyone. In today's class, we are going to discuss about arithmetic operator in sift to programming language. So arithmetic is nothing but Addison division, multivulation, modulus, increment and decrement. And then I'm going to create two variables A equal to ten and B equal to pi. So if you want to print the arithmetic operators, you have to type print A plus B. So that's the first arithmetic operator that is Addison. And then you need to change the symbol A minus B, A and B, A divided by B, a module of B, and then A plus plus. So it is nothing but post increment. And A minus minus. It is nothing but post decrement. In SIFT programming language, increment and decrement is not allowed. So if I try to run post increment and post decrement, so can see the output error. So I can see the error plus plus cannot be applied. So in CIF we cannot use post increment and post decrement. That is increment and decrement. We cannot use that in SIFT programming language. You have to remember that. So after that, I'm going to run the code. So you can see the output 15, five, two, 50 and zero. So these are all the output for the arithmetic operators. So that's it, guys. In today's class, we are discussed about arithmetic operator in SIFT. So you have to remember that increment and decrement is not allowed in Sift programming language. 7. Swift Class 6 : Logical Operator: Welcome, everyone. In today's class, we are going to discuss about logical operator in sift programming language. So there are three logical operators and are not. We are going to create two variables, A, cult ten and B cultic five. First, we are going to discuss about unlogical operator. For that, we are going to create two variables. Let A equal to ten and let B equal to five. So after that, we are going to print the logical operator one by one. First, we are going to print the logical operator. So we have to type print of A less than B and A greater than B. So in sift programming language, you have to type space between the operator and operant. You have to type space. So in logical operator, the both condition must be true. If any one of the condition is false, then the output will so false. So that's the concept of. So you have to remember that the syntax of sift is different than other programming language, so you have to time space between the operns and operator. So you have to run the code. So you can see the output falls. So one condition is non satisfied. First, the condition is non satisfied because A is not less than B. After that, we are going to discuss about R for that you need to type the code. A, greater than B, and then you have to type the symbol A less than B. So in R, any one of the condition is true, then the output will so true. If both condition are false, then the output will so false. So that's the difference. In and both condition must be true. But in R, any one must be true. If I run the code, you cannot see the output because I don't type the space between the elements. So you have to type A greater than B and A less than B, space, and then you have to run the code. So you can see the output false untrue. So space is very, very important in sift programming language. So after that, we are going to discuss about naught logical operator. So naught is nothing, but it will reverse the output. So if the value of logical operator is true, then the value of naught logical operator will so false. So that's the concept of naught. It will reverse the output. True becomes false, false becomes true. So how to tie the space between the operans and operator. If we don't type the space, no output will be generated. So if I run the code, so we can see the output true. We know that and will give the output false, but not will use the output true. That's the concept of and not. 8. Swift Class 7 : If Else: Welcome everyone. In today's class, we are going to discuss about I first conditional statement in SIP programming language. First, we are going to create variable for that. So first, we are going to create variable for the conditional statement. So you can also type A equal to ten or you can also type in equal to ten. So there are two ways for creating the variable using that data type. And then I'm going to print the second B equal to 20. After that, I'm going to use I you need to type the I K word. Inside that you need to type the condition A greater than B. After that, I'm going to print the output. If the condition of I is satisfied, then it will print A is greater than B. A is lesser than B. So you can type your own words. So if the if condition is no satisfied, then s will be printed. So I'm going to print B is greater. So if two conditions are not satisfied or if you want to create more conditions, you need to type if, and then you need to type the condition, A equal to equal to B. So then you need to print the value. A is equal to B. So this is how you can use IFs conditional statement in sift programming language. So we know that A is lesser than B. Then's condition will be generated in the output. So if I run the code, you cannot see the output because I didn't write space between the operator and parent. So you must remember that you need to tie space between operator and opernt and then you need to run the code. So you can see the output B is greater. So you can see the's condition is satisfied. 9. Swift Class 8 : While Loop: Welcome, everyone. In today's class, we are going to discuss about loops in Swift programming language. First, we are going to discuss about wild loop. So loops are very, very important in programming language. For example, if I want to print Hala world for more than ten times for default, I'm going to type Hala world, hala world, hala world using the print. For this problem, the loops are introduced in programming language. So loops are based on some condition. If the condition is satisfied, then it will print the output. For that, we are going to see an example. We are going to print Hala world for ten times using the wild loop. For that, you need to create variable for the hala world. Where is equal to color world, that is string data type. After that, you need to initialize the starting value. So you have to type I equal to zero or one. And then you need to type the keyword that is Y, condition, I ester are equal to ten. Inside the curly brackets, we are going to run the halor world. So the condition is I stern are equal to ten. The value of I is one, one less than are equal to ten. The condition is satisfied. Then the loop will be executed. So inside the loop, we are going to print hla world. So for that, you need to type print off. I will print the output ten times. And then you need to increment the value for printing the halor worth for ten time. So in Swift programming language, we cannot use increment or decrement. For that, you need to type the assignment operators. So you have to type I equal to I plus one. So you have to remember that you cannot use increment and decrement in Swift programming language. Also, you have to time space between the operant and operator. So first, the value of I is one. I is less than or equal to ten. The condition is satisfied, Hala world will be printed one time. Then the value of I will become two. The condition is two less than or equal to ten. The condition is satisfied, then the hala world will be printed second time. Then the value will be incremented, up to ten, the condition will be satisfied. When the value I becomes lawn. The condition is not satisfied because lawn is not less than ten, then the loop will be IP. So these are all the concept of loops in programming language. So if I run the code, you can see the output halo world is printed ten times. So this is how you can use Wil Loop in SIFT programming language. 10. Swift Class 9 : For Loop: Welcome, everyone. In today's class, we're going to discuss about how to print halo world for ten times using far loop. First, you need to type the variable for Hala world. So the syntax of R loop is different in sift to programming language. First, you need to type the far, and then you need to type the increment value, and then you need to type the in operator that is membership operator. And then you need to type the range one, two, ten. You can type your own range like zero to nine or 1210 or 1211 and based on your own choice, you can type the range. And then you need to type the Carly brackets. Inside the Carly brackets, you need to print the S. So contains the halor world. So this is the syntax for far loop in sift programming language. First, you need to type the keyword for, and then I in and then range. So you can type your own range zero to ten or zero to nine or one to ten, so that's your own choice and then run the code. So you can see the output, lo world is printed ten times. 11. Swift Class 10 : Break & Continue: Come, everyone, in today's class, we are going to discuss about break and continuous statement in SIFT programming language. So break is nothing but it will exit the loop when the condition is satisfied. Continue is nothing, but it will skip the particular value in the loop when the condition is satisfied. For then we are going to see the example of break and continue using far loop. First, you need to type the far loop syntax for I in one to ten, that's the range, and then you need to type the I condition. So if the value of I becomes four, then we will exit the loop using the break. And then we need to print the I value one by one. So break is nothing, but it will exit the loop when the condition is satisfied. The condition is I equal to equal to four. So if I run the code, you can see the output one, two, three. After the four, when the value becomes four, the output is exit. So if I type seven and run the code again, you can see the output up to six. So that's the use of break. It will exit the loop when the condition is satisfied. After that, we are going to use the continue. So continue will strip the particular value in the loop. So you can see all the values, but you cannot see the particular value that is seven. So seven will skip the loop. So that's it guys. In today's class, we discussed about break and continue, break will exit the loop, continue will skip the particular value in the 12. Swift Class 11 : Array: Come, everyone. In today's class, we're going to discuss about how to create array in SIFT programming language. So RA is one of the data type which contains the elements. First, you need to type the are keyword and then you have to type the array name equal te. You have to type the square bracket inside that, you have to type the values, ten, 20, 30, 40, and 50. So it will be considered as integer data type array. So after that, we are going to create the second data type array that is string. So you have to type are equal t square bracket off. You have to type the values like hello world. Inside the double quotation, you need to type. So it will be considered as string data type array. So after that, we are going to create array using different format. So you have to type X, colon, square bracket, equal to square bracket. One, two, three, are ten, four, you can type your own values. So it also will consider us integer data type array. So if you want to access any element in the array, you have to use the index position. So index start from zero and then goes to the element value, so zero, one, two, three, and then the element value. So that ten is the zero, 20 is the first, 30 is the second, 40 is the third, and 50 is the four. So if you want to print the ten, you have to use the index position. So you have to type print eight square bracket, you have to type index position zero. It will print the output ten, so you can see the output ten. So if I want to access world, you have to change the variable, and then you need to change the index position also. Index position is one. After that, you need to run the code, you can see the output world. So this is how you can access the array elements in the sift programming language. After that, if you want to print all the elements of the array, you need to use far loop. For that, you need to type the syntax. Far that's the keyword, and then you need to type N, and then you have to type the value of array A curly brackets inside that, you have to type print of I I. So you have to run the code. You can see the output, ten, 20, 30, 40, and 50. So this is how you can print the output of all elements using the far loop. 13. Swift Class 12 : Class & Objects: Welcome everyone. Now we are going to discuss about object oriented concept in CIF to programming language. So first, we are going to discuss about how to create class and object in Sif to programming language. You need to type the class, that's the keyword, and then you need to type the class name, that's the file name. So sample is the file name, and then you need to type the curly brackets. So this is how you can create the class in Sift to programming language. After that, if you want to create any variables, you have to type where keyword. And then you need to type the variable name equal to value. That is ten where A equal to ten. So after that, we are going to create a function for Addison. So you need to type function, that's the keyword, and then you need to type the function name, that is Addison. So funk is nothing but function. So after that, you need to remove all the values. You can also type int. So if you want Int, you can also type Int. Also, you can remove that. So this is how you can create fonts and ISP to programming language, and then we are going to print the value A plus B. So after that, we are going to create object in SIP to programming language. For that, you need to type, and then you need to type the object equal to so in Sift programming language, you don't need to type new keyword. You have to simply type the file name, that is the class name. It will create the object. So using the object, we can call the function. So OB dot, Addison off. So you have to type OB dot, Addison off. So it will call the output that is print of A plus B. So in the output, you can see 30. So 30 is the addition of two values, ten plus 20. So this is how you can create class, function, and then object. 14. Swift Class 13 : Inheritance: Welcome everyone. In today's class, we are going to discuss about inheritance in SIP to programming language. So inheritance is nothing, but the child class will inherit the parent class properties. So the properties can be the variables, methods or constructor. For that, we are going to see an example. First, you need to create the parent class. So you have to type class. So that's the keyword, and then you have to type sample. So that's the parent class, and then you have to type curly brackets. Inside that, I'm going to create variables for Addison. So where A equal to ten. You have to type child class. And then you have to type colon. So that's the syntax for inheritance in CIF to programming language. And then you need to type the parent class name that is sample. So this is how you can inherit the parent class in Sif to programming language. So you have to type colon. In other programming language, you have to type extents. And then we are going to create the variable B equal to 20, and then we are going to print A plus B. A will be inherited from the parent class. So after that, you need to create object. So you have to type OB equaltive and then you need to type the child class name. Child off. So you don't need to type new keyword, simply you have to type child off. It will create the object. So after creating the object, you need to create function. You cannot directly access the print in the class for that we are going to create funct and add off curly brackets inside that we are going to print A plus B. So after creating the function, you have to call that using the object of the child class. So you have to type OB dot add off. So in the output, you can see 30 is generated successfully using the inheritance. After that, we are going to create the function in the parent glass. We are going to discuss about how to access that function using the child class method. For that, I'm going to type funct and then display of parent class method. And then I'm going to call the function display off. If I run the code, you can see the output parent class and 30. So using the child class, we can inherit the properties of the parent class like variables and function. So this is the single inheritance. So there are many inheritance in programming language. 15. Swift Class 14 : Polymorphism: Welcome, everyone. In today's class, we are going to discuss about polymorphism in Sif to programming language. So there are two methods. First one is the method overriding and then method overloading. First, we are going to discuss about method overriding. So for method overriding, you have to type override keyword. Then only you can use method overriding in Sift to programming language. So we are going to see an example for method overriding. First, you need to create the parent class. So class sample is the parent class. And then we are going to create the function that is display. So method overheading is nothing, but both parent class and child class method name are the same. So that's the method override. So inside the function, I'm going to print parent method. So after that, I'm going to create child class, you to type class, child, and then you have to type colon, and then you have to type parent class name. We just ingrate the values. And then you have to type the function, function display. So these two display names are very similar. That is method override. Inside that, I'm going to print child method. But before the function, you need to type override. Then only you can override the method. After that, I'm going to create child class object to type where O B equal to child off. It will create the object for the child. So using that object, we can call the display. Ob dt, display off. So it will print the output child method. So you have to run the code, you have to see the output child method. So if you want to print the parent class method, then you have to create another object. Then only you can display the output. So using the child class object and overrid method, we can override. So I'm going to create another object for the parent class for printing the parent method. So I have to type the name of the parent class, sample off. After that, you have to call the function Ob dot, OB one dot display off. So it will print the output part method. And then child method is nothing but the second object. So that's it guys. In today's class, we'll discuss about method overriding.
