instant iOS crash

[roha99]

hello @cheebeez

thanks for this amazing package 🤗
it is working very nicely on Android but unfortunately my App is instantly crashing on iOS as soon as I call RadioPlayer.setStation(...);

output from my terminal:
radio_player/RadioPlayerService.swift:162: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value

it looks like this is related to the following pull request: #52

further investigation reveals that the crash is in fact NOT caused by calling RadioPlayer.setStation(...); but rather by calling RadioPlayer.play(); immediately afterwards

[roha99]

it appears that the assessment of @mz185 is correct
the crash occurs when a station is not yet initialized

for now I discovered the following workaround:

await RadioPlayer.setStation(...); // use await to ensure that the station is initialized
RadioPlayer.play();

@cheebeez it would be awesome if you could review #52 or at least add a notice to the main README to let people know that they need to use await

thanks again 🙏

unfortunately, I discovered yet another way to trigger the same crash

how to reproduce:

1. await RadioPlayer.setStation(...);
2. await RadioPlayer.play();
3. await RadioPlayer.reset();
4. tap play in the iOS control center
5. 💥

since this leads to a full app crash and cannot be mitigated by app developers, I am afraid this issue seems to be more serious than previously assumed
