Popping Sound

Hello everyone, We are building an iOS app using React Native that connects to a custom Bluetooth Low Energy (BLE) accessory. The accessory continuously sends small chunks of audio data to the app through BLE (basically every time the user speaks), which are then streamed in real time to our server via WebSocket for transcription and processing. We need to know if the following behavior is allowed by iOS runtime and App Store review policies: Can the app open a WebSocket connection in the background (not permanently, just briefly, several times a day) triggered by BLE activity from a registered accessory? Is there a limit to this? Clarifications: The app is not expected to remain permanently awake. Only during accessory-triggered events. WebSocket is required due to the real-time nature of streaming STT and delivering quick responses (via notifications). If allowed, are there any specific Info.plist declarations or entitlements we must include? Thanks in advance! Fran

Hi everyone, I’m working on an iOS MusicKit app that overlays a metronome on top of Apple Music playback, using ApplicationMusicPlayer. To line the clicks up perfectly I’d like access to low-level audio analysis data—ideally a waveform / spectrogram or beat grid—while the track is playing. I’ve noticed that several approved DJ apps (e.g. djay, Serato, rekordbox) can already: • Display detailed scrolling waveforms of Apple Music songs • Scratch, loop or time-stretch those tracks in real time That implies they receive decoded PCM frames or at least high-resolution analysis data from Apple Music under a special entitlement. My questions: Does MusicKit (or any public framework) expose real-time audio buffers, FFT bins, or beat markers for streaming Apple Music content? If not, is there an Apple program or entitlement that developers can apply for—similar to the “DJ with Apple Music” initiative—to gain that deeper access? Where can I find official documentation or a point of contact for this kind

I'm trying to do some realtime audio processing on audio served from an HLS stream (i.e. an AVPlayer created using an M3U HTTP URL). It doesn't seem like attaching an AVAudioMix configured with with an `audioTapProcessor` has any effect; none of the callbacks except `init` are being invoked. Is this a known limitation? If so, is this documented somewhere?If the above is a limitation, what are my options using some of the other audio APIs? I looked into `AVAudioEngine` as well but it doesn't seem like there's any way I can configure any of the input node types to use an HLS stream. Am I wrong? Are there lower level APIs available to play HLS streams that provide the necessary hooks?Alternatively, is there some generic way to tap into all audio being output by my app regardless of its source?Thanks a lot!

Hello, I have a simple example using StateObject and List. When I bind the List(selection:) to a property of the StateObject like this: List(selection: $viewModel.selectedIndex) { ... } I noticed that each time I push the view using a NavigationLink, a new instance of the StateObject is created. However, when I pop the view, the deinit of the StateObject is not called. When is deinit actually expected to be called in this case? Example code: import SwiftUI @main struct NavigationViewDeinitSampleApp: App { var body: some Scene { WindowGroup { NavigationStack { ContentView() } } } } struct Item: Hashable { let text: String } @MainActor fileprivate class ContentViewModel: ObservableObject { @Published var selectedIndex: Int? = nil init() { NSLog(ContentViewModel.init) } deinit { NSLog(ContentViewModel.deinit) } } struct ContentView: View { @StateObject private var model = ContentViewModel() let items: [Item] = { return (0...10).map { i in Item(text: (i)) } }() var body: some View { List(selection: $mode

I'm repeatedly hitting an issue when deploying Xcode Cloud builds to macOS from TestFlight. Once the build appears in TestFlight I hit the Install or Update button in TestFlight and after a couple of seconds of spinning-wheel the button goes back to it's original state and the app fails to install. There's no error pop-up but I've noticed an Error Domain=ASDErrorDomain Code=710 Invalid hash '***' expected 'yyy' error in console each time it happens. My project needs to deploy 2 different macOS/Catalyst apps (actually they are 2 different targets in the same project) and it seems completely random as to which will actually successfully install on which machine. For my last build, one of the 2 binaries was failing to install on a Mac Studio on 15.5, but the other was fine. All were fine on 3 other machines I tried. For my latest build, both binaries are fine on the Mac Studio but both now fail to install on an M2 Air on macOS 26 beta 2. I'm now extremely nervous about deploying to my TestFlight beta gr

I’m trying to enable Background Modes (specifically for audio, background fetch, remote notifications) in my iOS SwiftUI app, but I’m getting this error: Provisioning profile “iOS Team Provisioning Profile: [my app]” doesn’t include the UIBackgroundModes entitlement. On the developer website when I make the provision profile It doesnt give me the option to allow background modes. I added it to the sign in capabilities seccion in X code and matched the bundle ID to the provision profile and certificate etc but it still runs this error because the provision profile doesnt have the entitlements..

I'm getting this error when I launch my application on the iPhone 14 Pro via Xcode. Everything builds OK. Im using the audio kit plugin and Sound Pipe Audiokit. The error starts as soon as I start the app and will carry on repeatedly. I have background processing turned on as I'd like the sounds to play when the phone is locked via the headphones. I can't find anything online about this error. None of my catches are printing anything in the logs either. So I don't know if this is just something that pops up repeatedly or whether there is something fundamentally wrong. private func setupAudioSession() { do { let session = AVAudioSession.sharedInstance() try session.setCategory(.playback, mode: .default, options: [.mixWithOthers]) try session.setActive(true, options: .notifyOthersOnDeactivation) } catch { errorMessage = Failed to set up audio session: (error.localizedDescription) print(errorMessage ?? ) } } // MARK: - Background Task Handling private func setupBackgroundTaskH
