What you did

My project, which was running fine on macOS 15, panics on the developer beta.

What went wrong

thread 'main' panicked at /Users/me/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/objc2-foundation-0.2.2/src/generated/NSEnumerator.rs:7:1:
invalid message send to -[_TtGCs23_ContiguousArrayStorageCSo8NSScreen_$ countByEnumeratingWithState:objects:count:]: expected return to have type code 'q', but found 'Q'

Additional information

This might also be caused by bevy_hanabi, but I haven't isolated it. The last log before the panic is

2025-06-13T17:29:51.315434Z  INFO bevy_hanabi::plugin: Initializing Hanabi for GPU adapter Apple M2
