How to reproduce: Launch ptt app join channel call requestBeginTransmitting in delegate method didActivate audioSession prepare AVAudioRecorder and call record Error: AVAudioRecorder.record() returns false If I reinstantiate and run AVAudioRecorder.record() right away then it returns true. It happens only on first audio recording after app launch.

In next program SimpleClass do not call deinit causing memory leak. final class SimpleClass {     deinit {         print("deinit SimpleClass")     } } struct ContentView: View {     var body: some View {         Text("Empty")             .onAppear {                 simple = .init()             }     }     @State private var simple = SimpleClass() } Tested on iPhone 12 mini, iOS 16.2, Version 14.2 (14C18). Am I using @State wrapper wrong?

Hello, I'm trying to replicate UIImagePickerController photo taking ability with AVFoundation. What I do: invoke `photoOutput.capturePhoto(with, delegate) in delegate method photoOutput(_:didFinishProcessingPhoto:error:)) I retrieve UIImage with photo.fileDataRepresentation() The issue: Produced UIImage has imageOrientation == .right, always. At the same time if I use UIImagePickerController, and say put my iPhone in landscape right position then produced image in its delegate has correct imageOrientation == .down. How can I achieve the same results with AVFoundation given that my iPhone orientation is locked (so UIDevice.orientation will not work). So far my best guess that I need to use accelerometer for this but maybe I miss some setting which allows to recover correct image orientation? Thank you.

Hi, Objective: iOS 14, iPhone needs to connect to device on local network without knowing its hostname; only port is known. Do I understand it correctly that the only way to do it is to request com.apple.developer.networking.multicast entitlement and execute: guard let multicast = try? NWMulticastGroup(for: [ .hostPort(host: "224.0.0.251", port: 5353) ]) else { fatalError(...) } let group = NWConnectionGroup(from: multicast, using: .udp) group.setReceiveHandler(maximumMessageSize: 16384, rejectOversizedMessages: true) { (message, content, isComplete) in print("Received message from \(String(describing: message.remoteEndpoint))") } Then from message.remoteEndpoint I can infer hostname (with matching port, of course) to which I need initiate NWConnection?
