Home Is there any way to add a letter to the bottom left area of a UIKeyboardType.NumberPad?
 The UIKeyboardType.NumberPad looks like this: What I want it to look like is this: Is there a way to overlay a view in just that corner when the keyboard is up to add this single key? Is this possible with Swift 4? The reason I want to do this is for easy ISBN number input for users, and some ISBN numbers (10 digits) have an X in them.
