I'm an author of an AudioUnit host for iOS written in Objective C.
In iOS 14, it began crashing on instantiation of any AU instrument, but the same AUs work in other hosts. If I put a break in the completion handler for instantiateWithComponentDescription, I immediately see an error as soon as I step out (but not continue), before anything else is called:
Sometimes it's a 4097. The next call into the plugin crashes the host, of course. In the log, the only entry that catches my eye is this:
Could there be some sort of access I need to give the app? How could I get more debug information out of this?
