Hey folks, not sure if this is the best place to ask but I've looked all over and the Rust forums haven't been able to help much.
I have a cross-platform text-to-speech Rust library for use in game engines and such. Among the platforms I support are macOS and iOS via AppKit or AVFoundation, as appropriate.
My AppKit backend works fine on M1/Intel macs. Unfortunately, my AVFoundation backend doesn't. I unfortunately don't have an M1 to test on, but apparently it tries and fails to speak the first utterance and the cancellation callback runs. Subsequent utterances don't speak. I assume this will fail on iOS as well.
Apologies I can't get this to a more minimal example, but I'm not sure where the problem is. The code in question begins here. To duplicate the behavior in question, you'll need a Rust toolchain on an M1. Then, something like cargo run --example hello_world should do it, or RUST_LOG=trace cargo run --example hello_world for more detailed logging from the library itself.
Tips on debugging Rust/Objective C interop are also welcome. I think I enabled the Rust feature to trap and surface exceptions, but that hasn't gotten me anything and I'm kind of at a loss.
Thanks a bunch for any help.
