How can third-party iOS apps obtain real-time waveform / spectrogram data for Apple Music tracks (similar to djay & other DJ apps)?
Hi everyone, I’m working on an iOS MusicKit app that overlays a metronome on top of Apple Music playback. 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: 1. Does MusicKit (or any public framework) expose real-time audio buffers, FFT bins, or beat markers for streaming Apple Music content? 2. 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? 3. Where can I find official documentation or a point of contact for this kind of request? I’ve searched the

Xcode 26 Issue with functional of bridging header in Xcode project with both objective-c and swift
I'm in the process of add some swift code that is all objective-c. I have trouble with my actual app so I have worked on a prototype. There is what I have done Created a new Xcode project, selecting App and Objc Added a blank Swift file and accepted the generation of the -Bridging-Header. In project build setting, Yes for Defines Modules, Yes for Always Embed Swift Libraries Add appropriate .h file to Bridging header In Build Settings, in Swift Compiler - General, Bridging Header has correct path to the bridging header file Setup the single swift file in this was using @objc like this: @objcmembers class MySwiftClass: NSObject { func myMethod() { let output = ... } } When the project runs I execute in the objc ViewController: MySwiftClass *swiftObject = [[MySwiftClass alloc] init]; and get Use of undeclared identifier 'MySwiftClass'

[iOS 26.1 beta 2] allowCamera restriction not working properly on both supervised and BYOD devices
Details: Device: iPhone 12 Pro Max System: iOS 26.1 beta 2 Issue Description: When testing MDM device restriction capabilities on iOS 26.1 beta 2, I found that the allowCamera restriction does not work as expected. Observed Behavior: • On a BYOD device: When allowCamera is set to false, the Camera and FaceTime apps disappear from the Home Screen, as expected. However, third-party apps (such as WeChat) can still access the camera and take photos. • On earlier versions (e.g. iOS 26.0.1): Setting allowCamera to false correctly blocks all apps, including third-party apps, from accessing the camera. Initially, I assumed Apple might have changed this restriction behavior so that allowCamera only applies to supervised devices. However, after testing on supervised devices, I found that even there, when allowCamera is set to false, the Camera and FaceTime apps are hidden, but third-party apps can still use the camera. This indicates that the restriction is not functioning correctly in iOS 26.1 beta 2. Expectation: Whe

iOS26 WKWebView:Remote page becomes unresponsive after loading local file
Subject: iOS 26 WKWebView: Remote Pages Become Unresponsive After Loading Local HTML Files Description We're experiencing a critical issue with WKWebView in a React Native 0.64.3 application where remote web pages become completely unresponsive after loading local HTML files in iOS 26. It works well before iOS26. Environment: React Native 0.64.3 iOS 26.0 Xcode 26.0.1 Using custom WKWebView implementations in Native modules Problem Details App loads local HTML files using loadFileURL:allowingReadAccessToURL: Later, when loading remote pages via loadRequest:, the remote pages load successfully but become unresponsive to user interactions This occurs even when using different WKWebView instances The issue is reproducible 100% of the time once a local file has been loaded Restarting the app and loading remote pages directly works fine Code Example: // Loading local file (works fine) [self.webView loadFileURL:localFileURL allowingReadAccessToURL:accessURL]; // Later, loading remote page (loads but becomes unrespon

LockedCameraCapture Does Not Launch The App from Lock Screen
My implementation of LockedCameraCapture does not launch my app when tapped from locked screen. But when the same widget is in the Control Center, it launches the app successfully. Standard Xcode target template: Lock_Screen_Capture.swift @main struct Lock_Screen_Capture: LockedCameraCaptureExtension { var body: some LockedCameraCaptureExtensionScene { LockedCameraCaptureUIScene { session in Lock_Screen_CaptureViewFinder(session: session) } } } Lock_Screen_CaptureViewFinder.swift: import SwiftUI import UIKit import UniformTypeIdentifiers import LockedCameraCapture struct Lock_Screen_CaptureViewFinder: UIViewControllerRepresentable { let session: LockedCameraCaptureSession var sourceType: UIImagePickerController.SourceType = .camera init(session: LockedCameraCaptureSession) { self.session = session } func makeUIViewController(context: Self.Context) -> UIImagePickerController { let imagePicker = UIImagePickerController() imagePicker.sourceType = sourceType imagePicker.mediaTypes = [UTType.image.identifier, U

Inconsistent results involving code signatures and bundles
I admit I am doing something unusual, and I would not be surprised if it didn't work. I am surprised, however, because after performing the equivalent operations on four bundles, all of the bundles work fine on macOS 15.6.1, but only two of them work on macOS 26.1 (beta 2). I don't know what causes the different outcomes. What I am trying to do is get Java to pass the macOS 26 AppKit UI SDK linkage checking without having to rebuild the JDK using Xcode 26. Rebuilding works for the latest SDK, but it is very inconvenient and may not work for older JDKs. It usually takes a while before the JDK build team successfully transitions to a new Xcode release. My approach is to use vtool to update the sdk version in the LC_BUILD_VERSION load command of $JAVA_HOME/bin/java, which is the launching executable for the JDK. I performed this operation on four JDKs: 25, 21, 17, and 11. (I ran vtool on macOS 15.) It was completely successful on JDK 25 and 21. The JDK launches correctly on macOS 15 and macOS 26. On macOS 26, Ap

Reply to iPAD: achieve UserClient's privileges in background to have robust IOServiceAddMatchingNotification(...) as if ~[Background modes][Enable external communications].
Thanks a lot! ...adding external-accessory is not changing ANYTHING about how your app wakes/sleep in the background. You will not be allowed to use it, but that's because it's not relevant to your app. In my tests 2 weeks ago I (might be by my mistake) saw a correspondence between external-accessoryand the facts of callbacks from IOServiceAddMatchingNotification. Or at least correlation with the moments of such callbacks at the time of application moves from background to foreground. Having your unambiguous statement I tediously rechecked my environment now and I found 2 possible weak-points: A) I conducted the tests above having 2 identical DExts (for 2 different but very similar UserClient-Apps) formally enabled in Settings|Applications|Drivers. Though, of course, only one UserClient was active. I shall repeat the test (on near weeks) with single DExt physically installed. Another Q&A in TestFlight was being conducted in distant country. I shall reconfirm about the environment there. B)To distinguish t

Reply to Foundation Models inside of DeviceActivityReport?
Yeah, I see the following error when trying to prompt the on-device foundation model from within a device activity report extension (DeviceActivityReportExtension), which I believe is the same as what you mentioned: establishment of session failed with Unrecognized underlying error: Underlying connection was invalidated. Reason: failed at lookup with error 159 - Sandbox restriction ModelManagerError: got unrecognized error Underlying connection was invalidated. Reason: failed at lookup with error 159 - Sandbox restriction I am pretty sure that is as-designed. To give you more context, when responding your prompt, the model needs to communicate with the model manager, which is a system daemon that manages the inference requests. To protect the user’s privacy, however, the system doesn't allow a device activity report extension to move data outside the extension’s address space, and that prevents the model from creating a connection to the model manager. Having said that, if you have a compelling case

Can't Install WatchOS 26.1 beta 2
Beta two keeps hanging during the download process and says connect to wifi (which I am) or after hours it may download the beta 1.4gb file only to have to freeze in next processing step. I have tried all the resets, reinstalling both the watch and the phone running OS26.1 Beta 2 etc. The impact is the watch and the current software implementation is only getting a couple hours of battery usages before going dead

Reply to DriverKit. Plug/unplug test leads to MacOS panic
Could you share your understanding of the crash and give any hints on how we can fix it? So, let me actually start by commenting on this: At first, we assumed that the issue is with hardware. The first thing to understand here is that DEXTs are FULLY capable of panicking the kernel and probably always will be, particularly PCI DEXTs. The main benefit DEXTs provide is that they DRAMATICALLY improve overall system security and risk by constraining the range of what it's POSSIBLE for a component to do. Your DEXT only has access to a very limited set of kernel data, so that's the ONLY kernel data your DEXT interacts with. It's possible for a network DEXT to disrupt the network stack, but it's very difficult to see how it would disrupt the file system. However, your DEXT is still being given access to many of the same resources it would have access to as a KEXT, and many of those resources are inherently dangerous. In the case of the PCI family, that issue is quite direct— I don't know of any way to build a safe A

Share Extension / Sandbox Issue: sandboxd deny(1) hid-control
I'm developing a Share Extension for a macOS Electron application that allows users to share files from Finder to our application using the system Share menu. The extension compiles, signs, and notarizes successfully, but crashes during initialization due to sandbox restrictions blocking hid-control operations required by NSApplication. The Share Extension crashes during initialization with the following sandbox violation: Process: ShareExtension [pid] Identifier: com.xxxxxxxxxxxx.xxxxxxxxx.extension Operation: hid-control I would appreciate guidance on: The proper entitlements for third-party Share Extensions with App Sandbox Alternative approaches if Share Extensions have fundamental limitations for third-party developers Any documentation or sample code demonstrating Share Extensions outside the App Store
