View Hierarchy

How to initialise and add specific details about the view rectangle ?

We can create an instance of a view using the UIView initialiser and use the frame property to define the height, width and the x and y positions of the view (which is basically a rectangle). Finally we have to add it as a subview to a visible view so that we can see it


import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() view.backgroundColor = colorLiteral(red: 0.1019607857, green: 0.2784313858, blue: 0.400000006, alpha: 1) //use color literal to get a variety of color options let newView = UIView(frame: CGRect(x: 10, y: 100, width: 300, height: 50)) newView.backgroundColor = UIColor.white view.addSubview(newView) } }
