Here I am presenting how to create first basic program in Swift 3 language. First you need to have any basic programming language knowledge or not having then be ready to learn it from beginning.
Requirements for developments:
Xcode 8.2 has new Swift 3 language features with new iOS 10 compatible APi's.
First go to Application and open your Xcode 8.2.
After that you will see the screen
Then choose Create new Project and after that you will see next screen
Now we are choosing iOS platform for development and creating very basic project with the single view application option:
Then we need to give Product Name, this will represent your Bundle name and application name.
Application name you can change later as per your requirements. Then we need to click "Create" and after that your screen will look like this one below:
Inside this class you can see the file name is ViewController.swift and inside the class the name is also ViewController which is inheritance by the UIViewController super class and finally we're creating our first variable which name is myString of the type 'String'. Add the following under 'super.viewDidLoad()'
let myString = "Hello, World!"
We are going to print the content of this variable. First, select your simulator type at the top left hand side of the screen and then click on the "Run" button.
After that your output will be shown on terminal which is on bottom right hand side. Congratulations, This is your first Hello World program inside Xcode.
