Selector syntax for swift 3.0 [duplicate]

Add target like,

should now be written as #selector(buttonTapped(sender:)) or use #selector(buttonTapped(_:))

btnAll.addTarget(self, action: #selector(buttonTapped(_:)), for: .touchUpInside)

then change your function like,

@objc func buttonTapped(_ sender : UIButton){

 ....
 }
