Thank you for your response, Claude31. My questions specifically concern how I can fully test my right-to-left implementation using Xcode. I understand how to implement all of this (in theory), as it’s well-documented, for instance, in the WWDC talk Get it right (to left).

The AVCaptureSession.runtimeErrorNotification was not triggered during my recordings/tests.

I followed your suggestion and tried observing the AVCaptureInput.Port.formatDescriptionDidChangeNotification. The notification is received at the start of every new recording, not just the ones that subsequently fail. The following error/warning appears in the Xcode console before a subsequent faulty recording begins: CMIO_Unit_Converter_Audio.cpp:590:RebuildAudioConverter AudioConverterSetProperty(dbca) failed (1886547824)

The AVAssetWriter.Status is failed, and the error description says “The operation could not be completed”. A .caf file is created, but it contains no content.

Thank you for the hint! I have just uploaded two sysdiagnose files in the Feedback Assistant (both for recording audio from the Opal C1 camera and the Apple Studio Display microphone). I really hope this helps. Thanks so much for your support in advance.

Since your data source comes from a FetchRequest I recommend to change the sortDescriptor when the order has changed, using the .onChange modifier.

Would love to ship a macOS app that features WeatherKit but unfortunately I remain unable to receive any data from the API, too. Getting a bunch of errors like: [WeatherService] Encountered an error when fetching weather data subset Domain=WeatherDaemon.WDSJWTAuthenticatorService.Errors Code=1 "(null)" The operation couldn’t be completed. (WeatherDaemon.WDSJWTAuthenticatorService.Errors error 1.) Any advice?
