Practical Example for Developers

For developers looking to incorporate gesture recognition in their apps, Apple provides the UIGestureRecognizer class in Swift. Here’s a simple example of how to add a tap gesture recognizer to a view:

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap))
        self.view.addGestureRecognizer(tapGesture)
    }

    @objc func handleTap() {
        print("View tapped!")
    }
}

This code snippet demonstrates how to add a tap gesture recognizer to a view, which triggers the handleTap function when the view is tapped.
