Runtime exception `NSInternalInconsistencyException` more scheduler identifiers are registered

[krizzu]

Hey,

I'm receiving runtime exception:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Launch handler for task with identifier different.sdk.task_processing has already been registered'.

This happens when using react-native-background-fetch alongside different SDK, which also requires registering scheduler identifiers (and does registration on its own). A quick look at the code points to this line which registers everything found in BGTaskSchedulerPermittedIdentifiers entry. Normally I'd patch-package the library, but it comes as a xcframework.

Would it be possible to get an update?

else if ([identifier hasPrefix:@"com.transistorsoft"]) {
  [self registerBGProcessingTask:identifier];
}

alongside different SDK,

iOS Background fetch api can only be registered once. What other sdk are you using?

And is that other sdk going to also avoid registering tasks not registered to it?

I meant that Background Fetch registers other SDK identifiers. When it's time for other SDK to register identifiers, the exception is thrown.

And is that other sdk going to also avoid registering tasks not registered to it?

It's proprietary software, so I can only hope it does
