How to read tap and double-tap gestures

Paul Hudson    @twostraws   

Fully updated for Xcode 11 GM

Any SwiftUI view can have tap actions attached, and you can specify how many taps should be received before the action is triggered.

For example, this creates a text view that will print a message when tapped:

Text("Tap me!")
    .onTapGesture {
        print("Tapped!")
    }

And this creates an image view that will print a message when double tapped:

Image("example-image")
    .onTapGesture(count: 2) {
        print("Double tapped!")
    }
