How do I use animations and transitions?

In Swift, creating animations and transitions is an essential part of enhancing user experience in iOS applications. With built-in functions and methods, you can easily animate changes to properties of views or present new view controllers with engaging transitions.

Example of Animating a View

This example demonstrates how to animate the position and opacity of a UIView in Swift:

// Import UIKit import UIKit class ViewController: UIViewController { let animatedView = UIView(frame: CGRect(x: 100, y: 100, width: 100, height: 100)) override func viewDidLoad() { super.viewDidLoad() // Set initial properties animatedView.backgroundColor = .blue view.addSubview(animatedView) // Trigger the animation animateView() } func animateView() { UIView.animate(withDuration: 1.0, animations: { // Change properties self.animatedView.alpha = 0.0 self.animatedView.center = CGPoint(x: 200, y: 400) }, completion: { finished in // Completion block self.animatedView.alpha = 1.0 // Reset opacity }) } }
