Hi there, Is any way to detect if the device supports Center Stage? Now we have some properties that Apple presented: class var centerStageControlMode: AVCaptureDevice.CenterStageControlMode { get set } okay, it means that we can change centerStage mode but what's the point if device doesn't support it? var isCenterStageActive: Bool { get } class var isCenterStageEnabled: Bool { get set } it's fine we can set and get stage status But what if you wanna change it in your app? You give us a way to set enabled state that's why I'm trying to give user a possibility to change it in-app. How can I detect if the device supports it? Now only 1 idea to check current or all AVCaptureDevices, if at least one is wide-angle camera - it can be assumed that the feature is supported. But how true is this?

Hi, for a long time I can't detect a reason why my app is crashing. I just see a crash without detailed stack trace: [6799:2715220] * Assertion failure in -[FBSSerialQueue assertOnQueue], /Library/Caches/com.apple.xbs/Sources/FrontBoardServices/FrontBoard-626.8/FrontBoardServices/FBSSerialQueue.m:98 2020-08-10 11:42:08.779089+0300 [6799:2715220] * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'threading violation: expected the main thread' ** First throw call stack: (0x1a43d1344 0x1a40e6cc0 0x1a42ce878 0x1a4720160 0x1a965fc60 0x1a9612718 0x1a961299c 0x1a961289c 0x1a80523d4 0x1a814f734 0x1a81504b4 0x104b69e0c 0x10505205c 0x1050534d8 0x10505ac20 0x10505b834 0x105067270 0x1a40d9718 0x1a40df9c8) Okay, it's a classic problem when we change UI not in the main thread, but it doesn't look like. I fount last backtrace: Application Specific Information:** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'threading violation: expected the main thread' Last Exception Backtrace: 0	 CoreFoundation											 0x000000018f118794 __exceptionPreprocess + 224 1	 libobjc.A.dylib											0x000000018ee3abcc objc_exception_throw + 52 2	 CoreFoundation											 0x000000018f01b82c +[NSException raise:format:arguments:] + 92 3	 Foundation													 0x000000018f45316c -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:] + 124 4	 FrontBoardServices									 0x00000001942d7e84 -[FBSSerialQueue assertOnQueue] + 224 5	 FrontBoardServices									 0x000000019428dd88 -[FBSSceneImpl updateClientSettings:withTransitionContext:] + 72 6	 FrontBoardServices									 0x000000019428dfe8 -[FBSSceneImpl updateClientSettingsWithTransitionBlock:] + 148 7	 FrontBoardServices									 0x000000019428def8 -[FBSSceneImpl updateClientSettingsWithBlock:] + 108 8	 UIKitCore														0x0000000192d367b4 -[FBSScene(UIApp) updateUIClientSettingsWithBlock:] + 164 9	 UIKitCore														0x0000000192e2dad0 -[UIDevice(Private) _enableDeviceOrientationEvents:] + 136 10	UIKitCore														0x0000000192e2e788 -[UIDevice endGeneratingDeviceOrientationNotifications] + 52 11	WebRTC															 0x0000000104895e0c 0x0000000104834000 + 400908 12	libdispatch.dylib										0x000000018eddd9a8 _dispatch_call_block_and_release + 20 13	libdispatch.dylib										0x000000018edde524 _dispatch_client_callout + 12 14	libdispatch.dylib										0x000000018ed8a8a4 _dispatch_lane_serial_drain$VARIANT$mp + 604 15	libdispatch.dylib										0x000000018ed8b294 _dispatch_lane_invoke$VARIANT$mp + 412 16	libdispatch.dylib										0x000000018ed9478c _dispatch_workloop_worker_thread + 584 17	libsystem_pthread.dylib							0x000000018ee2fb74 _pthread_wqthread + 268 18	libsystem_pthread.dylib							0x000000018ee32740 start_wqthread + 4 I noticed 5 line in a trace, looks like something in a private framework (FrontBoardServices or FBS) called in an incorrect thread. By this method prototype I think that I'm changing status bar appearance (anyway it's UI). Am I right? How can I detect a crash line where I changed UI or do anybody know another this crash reason? I turned on main thread checker but also it doesn't work. Thanks,
