CustomKeyboardKit_TextFieldAxis_BugDemo

To use the demonstration:

1. Open the project in Xcode
2. Select a development team in the Signing & Capabilities editor
3. Launch the app on iPhone
4. Editing the first text field (without the axis argument) clearly shows the custom keyboard. Editing the second (with the axis argument) brings up the standard keyboard.

Presumably the custom keyboard should work whether the axis argument is supplied or not.
