Swift 3: Unrecognized selector sent to instance Xcode 8 [duplicate]

Answer 1

class ViewController: UIViewController {

    let customView = UIView()

    override func viewDidLoad() {
        super.viewDidLoad()

        let panGestureRecognizer = UIPanGestureRecognizer(target: self, action: #selector(handleTap(_:)))
        customView.addGestureRecognizer(panGestureRecognizer)
    }

    func handleTap(panGesture: UIPanGestureRecognizer) {

    }
}

Don't forget to add your custom UIView to the VC.
