Is it possible to use the Apple Native Keyboard as a base for a custom global Swift Keyboard extension? The use case is a keyboard that adds something to the typing processing, but doesn't change the look and feel of native keyboard.
Requirement is to add functionality overlay while preserving all the great native keyboard usability features.
Did you have a look at inputAccessoryView https://developer.apple.com/documentation/uikit/uiresponder/1621119-inputaccessoryview
It's also available as a "settable/read-write" property on UITextField and UITextView so you don't have to do the "redeclare this property as read-write in a UIResponder subclass" dance as mentioned in the above link. Related is an optional inputAccessoryViewController.
