How to disable pasting in a TextField in Swift?

Question

I\'ve got a TextField with a numberPad and the function runs only if it contains numbers.

The user will crash the app if they paste letters

I did use this code. This is working.

override func canPerformAction(_ action: Selector, withSender sender: Any?)  Bool {

    if YOURTEXTFIELD.isFirstResponder {
        DispatchQueue.main.async(execute: {
            (sender as? UIMenuController)?.setMenuVisible(false, animated: false)
        })
        return false
    }

    return super.canPerformAction(action, withSender: sender)
}
