I'm developing an audio player app that uses AVAudioFile to read PCM data from various formats. I'm experiencing severe performance issues when seeking in FLAC, while other compressed formats (M4A/AAC) work correctly. I don't intend to use them in my app, but I also tested mp3 files just by curiosity and they also have this issue. Environment: macOS 26 (Tahoe) Xcode 26.3 Apple Silicon (M1) The issue: After setting AVAudioFile.framePosition to a position mid-file, the subsequent call to AVAudioFile.read(into:frameCount:) blocks for an unreasonable amount of time for FLAC and MP3 files. The delay scales linearly with the seek target, seeking near the beginning is fast, seeking toward the end is proportionally slower, which suggests the decoder is decoding linearly from the beginning of the file rather than using any seek index. (My app deals with “images” of Audio CDs ripped as a single long audio file.) The issue is particularly severe when reading files from an SMB network share (server on Ethernet,

Hi everyone, I'm building an iOS app that uses a DeviceActivityMonitor app extension as part of the Screen Time / Family Controls API. Every time I try to upload my IPA to App Store Connect, the validation fails with this error: Invalid Info.plist value. The value of the NSExtensionPointIdentifier key, com.apple.deviceactivity.monitor, in the Info.plist of 'Alexandria.app/PlugIns/AlexandriaActivityMonitor.appex' is invalid. Error Domain=IrisAPI Code=-19241, iris-code=STATE_ERROR.VALIDATION_ERROR What I have verified (everything looks correct): NSExtensionPointIdentifier = com.apple.deviceactivity.monitor NSExtensionPrincipalClass = AlexandriaActivityMonitor.AlexandriaActivityMonitorExtension (correctly resolved in the compiled binary, verified with plutil -p) The Swift class correctly subclasses DeviceActivityMonitor CFBundleShortVersionString matches the main app Both the main app and extension provisioning profiles explicitly contain com.apple.developer.family-controls = true (verified by inspecting embedde

Hi, I'm experiencing an issue where all RealityView content disappears when the user selects Lock In Place from the window management menu (long press on close button). Follow Me works correctly and this happens in Testflight builds only not reproducible when I run locally I have reproduced this with a minimal project containing nothing but a simple red cube — no custom anchors, no app state, no dependencies. Steps to Reproduce: Open an ImmersiveSpace. A red cube is placed 1m in front of the user via RealityView. Long press the X button on any floating window Select Lock In Place. The cube disappears immediately. Expected: Cube remains visible after window is locked Actual: Cube disappears. Minimal reproducible code: var body: some View { RealityView { content in let cube = ModelEntity( mesh: .generateBox(size: 0.3), materials: [SimpleMaterial(color: .red, isMetallic: false)] ) cube.setPosition(SIMD3(0, 1.5, -1), relativeTo: nil) content.add(cube) } } } Device: Apple Vision Pro visionOS vers

I am planning to run the AccessoryNotifications framework on xcode26.4 and ios26.4, please refer to the documentation https://developer.apple.com/documentation/accessorynotifications I couldn't find a complete demo, but I found a demo based on AccessorySetup Kit, ASK Sample https://docs-assets.developer.apple.com/published/89f5eef578ef/SettingUpAndAuthorizingABluetoothAccessory.zip. So I plan to practice the entire process of AccessoryNotifications based on this demo. Find accessories based on ASK Sample and connect them, OK Call requestForwarding (for:), OK Add AccessoryData Provider extension to receive system notifications But this step failed. I added an extension according to the documentation, but the following method will not be executed func activate(for session: NotificationsForwarding.Session) func add(notification: AccessoryNotification alertingContext: AlertingContext, alertCoordinator: AlertCoordinating) {} I found the following error log in console.app Error 16:38:17.582340+0800 usernotification

I am trying to preview my SwiftUI views but Xcode Preview Canvas failing. I tried everything that I found at internet but nothing works. Finally I created a new iOS project that contains only a view import SwiftUI struct ContentView: View { var body: some View { VStack { Image(systemName: globe) .imageScale(.large) .foregroundStyle(.tint) Text(Hello, world!) } .padding() } } #Preview { ContentView() } Even this view cannot be previewed The error is Simulator was shutdown during an update Simulator [3E0DB935-C4C2-4566-BA48-8E21564C207C] failed to boot and may have crashed. I tried to restart xCode, restart Mac, download ios 26.0 sdk and created a simulator with that sdk but nothing helped. Do you have an idea?

We built an open-source macOS menu bar app that turns speech into text and pastes it into the active app — using SpeechAnalyzer for on-device transcription, ScreenCaptureKit + Vision for screen-aware context, and FluidAudio for speaker diarization in meeting mode. Here's what we learned shipping it on macOS 26. GitHub: github.com/Marvinngg/ambient-voice Architecture The app has two modes: hotkey dictation (press to talk, release to inject) and meeting recording (continuous transcription with a floating panel). Dictation Mode Audio capture uses AVCaptureSession (more on why below). The captured audio feeds into SpeechAnalyzer via an AsyncStream: let transcriber = SpeechTranscriber( locale: locale, transcriptionOptions: [], reportingOptions: [.volatileResults, .alternativeTranscriptions], attributeOptions: [.audioTimeRange, .transcriptionConfidence] ) let analyzer = SpeechAnalyzer(modules: [transcriber]) let (inputSequence, inputBuilder) = AsyncStream.makeStream() try await analyzer.start(inputSequence
