After upgrading to iOS 17, Thread Performance Checker is complaining of priority inversion when converting a CVPixelBuffer to UIImage through a CIImage instance. It might be a false-positive or an issue? - (UIImage *)imageForSampleBuffer:(CMSampleBufferRef)sampleBuffer andOrientation:(UIImageOrientation)orientation { CVPixelBufferRef pixelBuffer = CMSampleBufferGetImageBuffer(sampleBuffer); CIImage *ciImage = [CIImage imageWithCVPixelBuffer:pixelBuffer]; UIImage *uiImage = [UIImage imageWithCIImage:ciImage]; NSData *data = UIImageJPEGRepresentation(uiImage, 90); } The code snippet above, when running in a thread set to the default priority results in the message below: Thread Performance Checker: Thread running at User-interactive quality-of-service class waiting on a lower QoS thread running at Default quality-of-service class.

What one should be concerned before changing a framework's bundle ID?

In EventKit framework, it seems that EKCalendarType for a EKCalendar result describing a calendar called "Siri Suggestions" has type of 5, but its not defined neither documented in EKEvent/EKTypes.h. Do you have any idea why it is not explicitly defined? Thank you, Alberto
