What is a tap gesture?
Tap gestures detect one or more fingers touching the screen briefly. The fingers involved in these gestures must not move significantly from the initial touch points, and you can configure the number of times the fingers must touch the screen.

Adding a Tap Gesture Recognizer in Interface Builder
You don't need to switch between the code editor and Interface Builder. Open Main. storyboard and drag a tap gesture recognizer from the Object Library and drop it onto the view we added earlier. The tap gesture recognizer appears in the Document Outline on the left.
