UITapGestureRecognizer in Swift language

let hideTap = UITapGestureRecognizer(target: self, action: #selector(hideKeyboardTap))
func hideKeyboardTap(recognizer: UITapGestureRecognizer){
    self.view.endEditing(true)
}

hideTap.numberOfTapsRequired = 1
self.view.isUserinteractionEnabled = true
self.view.addGestureRecognizer(hideTap)

Xcode reports "swift compiler error: Expected declaration" when I run the above code. There must be mistake in this line hideTap.numberOfTapsRequired = 1but I could not find out. Would you please help me? Thanks.

you can try same this :

override func viewDidLoad() {
        super.viewDidLoad()       
        let hideTap = UITapGestureRecognizer(target: self, action: #selector(self.hideKeyboardTap(_:))
       hideTap.numberOfTapsRequired = 1
       self.view.isUserinteractionEnabled = true
       self.view.addGestureRecognizer(hideTap)
    }

func hideKeyboardTap(recognizer: UITapGestureRecognizer){
    self.view.endEditing(true)
}

Write like this : 

override func viewDidLoad() {
super.viewDidLoad()

let tap = UITapGestureRecognizer(target: self, action: #selector(doubleTapped))
tap.numberOfTapsRequired = 2
view.addGestureRecognizer(tap)
}

func doubleTapped() {
// do something cool here
}
