An update to Xcode 14 appeared in the Mac App store today 2022-11-12. After updating Xcode from the App store app on my M1 MacBook, and plugging in an iPad, also updated today 2022-11-12 to iOS 15.7, Xcode says: "Failed to prepare the device for development". A restart of both the Mac and the iPad doesn't fix this issue. Is there a way to get Xcode 14 to debug an 15.7 iPad? Or is a different build required? There also is no 15.7 directory inside Xcode's iPhoneOS DeviceSupport directory.

The BSD network call: getifaddrs() returns an IPV4 address for the WiFi network connection on Catalina and iOS 13, but appears to return only IPV6 addresses on Big Sur and iOS 14. Is this intended behavior? If so, where is this documented?

I have one iOS app that is an iPad touchscreen virtual musical instrument. I have another app that is an audio visualizer (36-th octave spectrum analyzer). I used to use inter-app audio to pipe audio samples from the first app to either the second app, or to GarageBand for recording. But inter-app audio has been deprecated. My question is what is Apple's suggested method (API's etc.) to get audio samples generated in one UI app to play and display in another UI app (say on an iPad, where both apps can be on the display) in performance-near-real-time without using inter-app audio?
