Swift 5.1 Example for three view

Step:1 -> Add storyboard view and add outlet viewController UIView

@IBOutlet var firstView: UIView!
@IBOutlet var secondView: UIView!
@IBOutlet var thirdView: UIView!

Step:2 -> Add storyBoard view Tag

Step:3 -> Add gesture

override func viewDidLoad() {
        super.viewDidLoad()

        firstView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(self.tap(_:))))
        firstView.isUserInteractionEnabled = true
        secondView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(self.tap(_:))))
        secondView.isUserInteractionEnabled = true
        thirdView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(self.tap(_:))))
        thirdView.isUserInteractionEnabled = true
    }

Step:4 -> select view

@objc func tap(_ gestureRecognizer: UITapGestureRecognizer) {
        let tag = gestureRecognizer.view?.tag
        switch tag! {
        case 1 :
            print("select first view")
        case 2 :
            print("select second view")
        case 3 :
            print("select third view")
        default:
            print("default")
        }
    }
