What functions or techniques are used to detect and handle user tap events on the screen?

In iOS, the following techniques are commonly used to handle user taps on the screen:

• UITapGestureRecognizer — recognizes single or multiple taps on a UIView.
• Overriding the touchesBegan(_:with:) method and other methods from UIResponder for lower-level touch handling.

Example of using UITapGestureRecognizer:

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

@objc func handleTap() {
    print("Screen was tapped")
}

This approach is convenient for adding tap handling without needing to override UIResponder methods.
