What is view controller in iOS Swift?

The some keyword was introduced in Swift 5.1 and is used to define an Opaque Type. … So, in SwiftUI case, “some View” means that the body will always be implementing the View protocol , but the concrete implementation type does not need to be known by the caller.

Views and controls are the visual building blocks of your app’s user interface . Use them to draw and organize your app’s content onscreen. Views can host other views.

View objects are used specifically for drawing content onto the screen of an Android device . While you can instantiate a View in your Java code, the easiest way to use them is through an XML layout file. An example of this can be seen when you create an simple “Hello World” application in Android Studio.

The View Controller is the parent of all the views present on a storyboard . Each application has at least one ViewController. It facilitates the transition between various parts of the user interface. The UIViewController is the parent class of all the ViewControllers.
