I am writing audio content to a m4a file with ExtAudioFileWriteAsync and it is working perfectly. However, I would also like to add meta data to the exported file.
Is this at all possible? If so, how?
Any help would be much appreciated.

I ended up doing it with AVAssetExportSession, loaded the file I am trying to edit into an AVURLAsset, adding the metadata to the export session, then saving the export.
