When compiling the codebase with Xcode 27 and running it on a simulator or real device (with iOS 27 or iOS 26.x) the app keeps crashing in certain situations with the error "Thread 1: EXC_BAD_ACCESS (code=257, address=0x80000001097a409e)".
The exact same codebase is working just fine on Xcode 26.5.
I’ve tested changing the Xcode 27 toolchain to a custom one (6.3.2) but it still crashes. I’ve also tried to usual steps to delete the derived data folder and clear the cache. Nothing worked.
Here's the Feedback ID I've opened: FB23035297.
Is this happening to anyone else? Any idea?
