Lets say I have App A with App Group G. Is it possible to build and distribute a compiled binary framework F that lives within App Group G that can be used by 3rd party developers (not the same team)? My use case: A provides some local on-device data collection service (read & write). F provides an API to write to As data collection (write only). 3rd party developer should be apple to write data through F but not be able to read such data. I do not want to use a web server.
