Current bug behaviour

When building a Flutter app using the latest audioplayers package on iOS with Xcode 16.2, the build fails due to multiple Swift compiler errors in the audioplayers_darwin plugin.

Environment

• Flutter version: 3.32.4 (stable)
• macOS: 14.5 (23F79) (Darwin ARM64 via Rosetta)
• Xcode version: 16.2
• Plugin version: audioplayers:^6.5.1

Expected behaviour

When I run, I try to build my app on iOS (Just in iOS), I got an error

This workaround worked for me with the above same setup, you have:

dependencies:
  audioplayers: 6.4.0 ( => I have this configured, yours might be different and also fine)

dependency_overrides:
  audioplayers_darwin: 6.2.0

I hope this helps.
