Can anyone explain why I would be getting this warning ? [Internal] Thread running at User-interactive quality-of-service class waiting on a lower QoS thread running at Default quality-of-service class. Investigate ways to avoid priority inversions. The code (NB: This method is called on the main thread) - (void)parseAudioTracks:(NSArray<AVAssetTrack *> *)audioTracks { NSMutableArray<AVAudioMixInputParameters *> *inputParameters = [NSMutableArray arrayWithCapacity:audioTracks.count]; NSMutableArray *tracksNames = [NSMutableArray array]; NSMutableArray *tracksChannels = [NSMutableArray array]; NSUInteger lastChannel = 0; for ( NSUInteger i = 0 ; i < audioTracks.count; i++ ) { AVAssetTrack *track = audioTracks[i]; for ( AVMetadataItem *item in track.metadata ) <-- WARNING HERE ...```

I'm the developer of a small utility for Mac called "MusicDeviceHost". https://apps.apple.com/us/app/musicdevicehost/id1261046263?mt=12 As the name suggests, it is a host application for audio units (music device components). See also "Using Sound Canvas VA with QMidi": https://youtu.be/F9C4BiBR A problem occurs while trying to authorize the "Sound Canvas VA" component, Roland Cloud Manager (v3.0.3) returns the following error: “Authorization Error - RM Service not connected Error Connecting to Roland Cloud Manager Service” I guess the error is caused by some permission denied to the sandboxed application version. The NOT sandboxed version of MDH actually works flawlessly. I am using the following entitlements: com.apple.security.app-sandbox com.apple.security.network.client So connecting to the service should work, because "com.apple.security.network.client" is enabled. At Roland, they say: "Cloud Manager isn't supported in a sandboxed environment." But as far as I can see, MainStage and other sandboxed apps works fine... So what is the right answer? Is there someone out there with the same issue? Thanks for helping :)
