Crash in MFTextStateGlyphData

[RobbeVDC]

Happens on iOS 9 and iOS 10 and not sure why.

-[MFTextStateGlyphData showCodes:length:]: unrecognized selector sent to instance 0x78a91400
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MFTextStateGlyphData showCodes:length:]: unrecognized selector sent to instance 0x78a91400'

Any idea what's going on?

Any update on this?

100 % reproducible I'm afraid. Happens after calling glyphBoxesForPage: in the MFDocumentManager.h file.
When this method is called, the app crashes:

I have updated to the latest version on the develop branch. It still crashes on exactly the same thing, however there is some more info in the logs:
You must override showCodes:length:adjustment: in a subclass

Any update on this please?
