How to programmatically add Auto Layout constraints in Swift?

Hi everyone! I just started learning iOS development in Swift and I'm having trouble with programmatically adding constraints. I can work with Interface Builder more or less, but when I need to create UI in code — everything becomes difficult. I have a simple screen: I create a UIView (let's call it `myView`) with a blue background and I want it to be 200x200 points and centered on the screen. Here's my current code: ```swift import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let myView = UIView() myView.backgroundColor = .blue myView.translatesAutoresizingMaskIntoConstraints = false view.addSubview(myView) // Trying to add constraints, but nothing
