Swift create new view controller

In iOS Development, a View Controller is responsible for displaying the data of our iOS application on the screen . It acts as an interface between its Views (created by the developer) and the application data. Each ViewController in the Storyboard is assigned a Class that inherits the UIViewController class.

A SWIFT file is a source code file written in Swift , a programming language introduced by Apple with iOS 8 and OS X Yosemite. It is designed for writing and compiling apps and can be used with Xcode beginning with Xcode 6.

A view controller manages a single root view, which may itself contain any number of subviews . User interactions with that view hierarchy are handled by your view controller, which coordinates with other objects of your app as needed. Every app has at least one view controller whose content fills the main window.
