Unable to build project in Xcode 14.3 beta due to missing arc dir at /Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib

Downloaded Xcode 14.3 this morning and it will not build the project. It fails building the CocoaPods project with this error: It varies which pod causes the failure, but always the first to link. cd'ing into there confirms that there is no arc dir. The regular Xcode app (Version 14.2 (14C18)) runs just fine. Any ideas? Potentially useful information: Project with objc, swift and c Uses CocoaPods Uses automatic reference counting macOS Ventura 13.2.1 (22D68) Version 14.3 beta (14E5197f)

AVAudioSessionErrorCodeCannotStartRecording when recording in the background with iOS 13

Hello. I am working on adding support for iOS 13. Previously the app has been able to record audio for transmition while in the background when the user presses an external button, such as one from a wired headset. This is important as many users such as first responders are currently able to talk by pressing a button, rather than pulling the phone out of a pocket, unlocking it, launching the app etc. I can't find any sort of recording in the background permission to put in the info plist. Are there any special categories or options needed in the Audio Session to permit this on iOS 13? Failing that, is there a way to launch the app when the user presses the button ( wired or bluetooth le) so the recording can start?How does the Messages App allow recording on the notification? Inter-App Audio?Thanks.
