ExtAudioFileWrite in iOS failing with error code -66560

Question

I'm using ExtAudioFileWrite to write audio data into a file. But when it is interrupted by an alarm, although the file is saved, I get this error. What kind of error is this?

Answer 1

To decode an error from core audio, search the header files of the framework. In this case, you can look in ExtendedAudioFile.h for -66560, which will lead you to: kExtAudioFileError_CodecUnavailableInputNotConsumed
