CLMonitor WWDC video, it says the same name can be reused await CLMonitor("greeting") but the production iOS 17 API actually crashes. Is this the correct behaviour? (See screenshot 1) for try await events in monitor.events should work in from the WWDC video, but the production iOS 17 API does not work and need to insert await after in keyword. Also, never received any events from the monitor (See screenshot 2) WWDC Video: https://developer.apple.com/wwdc23/10147

Hi Apple support, I'm using AVMultiCamPip as a project starting base and I have the following setup(sample[1]). It connects without headphones but generate a runtime error(sample[1]) with headphones. I'm running on iPhone Xs with iOS 14.3 The source code I'm using is the sample AVMultiCamPip code. How should I config the external headphone mic to prevent the runtime error to occur? sample[1] 2021-01-23 11:10:54.216702-0500 AVMultiCamPiP[3760:649414] Metal GPU Frame Capture Enabled 2021-01-23 11:10:54.218037-0500 AVMultiCamPiP[3760:649414] Metal API Validation Enabled (lldb) po (notification.object as!
