In iOS 16, it always show
-[nw_ip_channel_inbox initWithPath:flow:parameters:delegate:] flow (some uuid interface: utun4, viable, assigned) does not specify local endpoint
after call [NWListener start:].
This issue doesn't happen in iOS 15. Although it looks like a crash, the app keeps working and getting data. What does "specify local endpoint" mean?

To my knowledge, you can use the AudioUnitSetProperty function to set the kAUVoiceIOProperty_VoiceProcessingEnableAGC property to disable AGC in AUv2.
However there is no equivalent functionality available in AUv3. The closest option I found is the shouldBypassEffect property.
How to disable AGC using the AUv3 API ?
Whenever I turn off Wi-Fi in the Setting.app, NEHotspotConfigurationManager.apply() doesn't get triggered.
If I restart my app, the apply function responds with
Error Domain=NEHotspotConfigurationErrorDomain Code=8 "internal error." UserInfo={NSLocalizedDescription=internal error.}
After restarting the device, this issue occurs again.
I observed this issue on iOS 16.6, and I'm not sure if it's the same on other versions.
I try to use "Download container" on "Devices and Simulators".
But on iOS 17, xcappdata file size is 4KB and ''AppData" folder is empty.
On iOS 15, xcappdata file size is 2MB and success downloaded.
Xcode show these error when I unplug iOS 17 and plugin iOS 15.
The system failed to get a list of files on the remote device.

PS.
I had turn on [Airplane mode] on iOS 17.
Position of AVAudioSession is different when I use the speaker.
try session.setCategory(.playAndRecord, mode: .voiceChat, options: [])
try session.overrideOutputAudioPort(.speaker)
try session.setActive(true)
let route = session.currentRoute
route.inputs.forEach{ input in
print(input.selectedDataSource?.location)
}
In iPhone 11(iOS 17.5.1),
AVAudioSessionLocation: Lower
In iPhone 7 Plus(iOS 15.8.2),
AVAudioSessionLocation: Upper
What causes this difference in behavior?
