From the documentation:

Important

The UIAlertController class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified.

You're probably better off using an existing library that implements this, such as e.g. https://github.com/vikmeup/SCLAlertView-Swift, or implementing your own alert from scratch.
