  1. Use this technique for custom textField

       class SkyFloatingLabelTextField: UITextField {
            open override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
                if action == #selector(UIResponderStandardEditActions.paste(_:)) {
                    return false
                }
                return super.canPerformAction(action, withSender: sender)
            }
        }

  2. Create a custom class inherited from SkyFloatingLabelTextField class and then assign.

    class FloatingTextField: SkyFloatingLabelTextField {
        open override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
            if action == #selector(UIResponderStandardEditActions.paste(_:)) ||
                action == #selector(UIResponderStandardEditActions.copy(_:)) {
                return false
            }
            return super.canPerformAction(action, withSender: sender)
        }
    }
    

    If you want for the whole project and all textfield add this extension.

    extension SkyFloatingLabelTextField {
        open override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
            if action == #selector(UIResponderStandardEditActions.paste(_:)) ||
                action == #selector(UIResponderStandardEditActions.copy(_:)) {
                return false
            }
            return super.canPerformAction(action, withSender: sender)
        }
    }
