uitextfield

I want to write a custom code on double tap on UITextField and block the default text editing and popup of the keyboard. I've tried the following and nothing has worked for me so far. Kindly help me solve this problem. let gestureArray = NamTxtBoxVal.gestureRecognizers var tapGesture = UITapGestureRecognizer() for idxVar in gestureArray! { if let tapVar = idxVar as? UITapGestureRecognizer { if tapVar.numberOfTapsRequired == 2 { tapGesture = tapVar NamTxtBoxVal.removeGestureRecognizer(tapGesture) } } } let doubleTap = UITapGestureRecognizer(target: self, action: #selector(namFnc(_:))) doubleTap

I want customized UITextfield which has placeholder behavior same as android also I want error label within UITextfield. Recently I have seen in android.
