I have this code in a compose multiplatform which uses coreML to do realtime pose detection. It runs and works for a while but eventually I always get a badexec crash, sometimes quickly, sometimes it will run happily for an hour before crashing. My iOS experience is limited so I am not reall sure what I am doing when it comes to managing the memory, but I haven’t been able to figure out what I am doing wrong to cause this issue.

It is an open source project so you can see the full code here Making sure you're not a bot!
