We never received customer report this crash, and we could not see during development phase However we can see this crash quite often on crash analytics. I have gone through UIAlertController in code level, it always creates new one instead reusing it. Please help me identify why this occurs? Much appreciated crash_session_2ecf1bdde30e402f9df795ea7681272b_DNE_0_v2_stacktrace.txt

Question regarding to Service extension handling.
Hi All, Recently I received customer report that my service extension suddenly stop working, and it worked fine for a while. I reviewed the Customer report, and found Service extension stop at in the middle of nowhere, and it does not wake up afterwards. one of the device has service extension log, but I can't parse it. once service extension get into this state, rebooting device / terminating app does not help, only remove/re-install will make it work again according to customer's report. Here are my question: How to detect Service extension stop working? it is hard to reproduce on my side. Can anyone help me to parse the crash and identify the root cause? Thanks in advance.

Wrong Deactivate audio session event was received when Ending cellular call
Hi All I recently found that wrong deactivate audio session event was received on app when user end Celluar call. Here is my step: App report to CallKit an incoming call and answer it. Device receive Celluar call, and user choose Hold/Accept. and app is notified by held action on Call Provider delegate. User end Celluar call. Expected : app is supposed to receive activate Audio session or unheld event Real result: app receive did deactivate event. which cause app to shut audio session. Can anyone correct on this scenario? Thanks,

audiosession category was wrongly updated from playandrecord to playback, which cause no audio on Audiosession by counting down alarm.
Hi All, I am working on VoIP application, when a call receive, my app will activate audio session with playandrecord. However, the issue is during a call, if there Alarm triggered, like set Clock Timer count down for 5 seconds, when 5 seconds clock Alarm triggered, my app will receive Category update event, and switch my audio session from playandrecord to playback. the alarm does not send interrupt notification. AVAudioSessionRouteChangePreviousRouteKey = "<AVAudioSessionRouteDescription: 0x282bd5e60, \ninputs = (\n \"<AVAudioSessionPortDescription: 0x282bd66d0, type = MicrophoneBuiltIn; name = iPhone Microphone; UID = Built-In Microphone; selectedDataSource = (null)>\"\n); \noutputs = (\n \"<AVAudioSessionPortDescription: 0x282bd63f0, type = Receiver; name = Receiver; UID = Built-In Receiver; selectedDataSource = (null)>\"\n)>"; AVAudioSessionRouteChangeReasonKey = 3; }} What is best to check such event to reactive audio session with correct category. if I do it on cellular call, once the Alarm is triggered, it will play vibration, there is tone at all.
