Hello, I want to use universal links in my application, for which I need to get the TeamID and BundleId, for apple-app-site-association file. Can you please tell me, do I have to buy an Apple Developer Account at the time of development to do this, or can I get it all for free at the time of development?

I am requesting technical clarification and a formal feature addition regarding the availability of per-frame calibration data for Standard RAW captures on iPhone 17 and 17 Pro. The Technical Gap: Currently, AVCaptureVideoDataOutput provides a direct path to the AVCameraCalibrationData object, allowing real-time access to the Intrinsic Matrix, Radial/Tangential Distortion coefficients, and Lens Shading Maps. However, this same level of geometric transparency is missing from the AVCapturePhoto RAW/ProRAW delegate. While standard RAW files contain some metadata, they lack the physics sidecar required for precision manual alignment. Because the lens assembly in the iPhone 17 Pro is dynamic shifted constantly by Optical Image Stabilization (OIS) and high-speed Voice Coil Motors (VCM) for focus a static or factor calibration is mathematically insufficient for high-precision workflows. The Problem: Without the 1:1 hardware state at the millisecond of exposure, we cannot perform accurate geometric reconstruction from RAW stills. We are forced to choose between the high dynamic range of a RAW sensor dump and the geometric precision of the video pipeline. Final Questions: Is there a documented, supported method to force the inclusion of the AVCameraCalibrationData object or a raw metadata sidecar in the AVCapturePhoto workflow? If not, can Apple provide parity between the Video and Photo APIs so that the "rawest" data (RAW) is accompanied by the "rawest" physics (Calibration Data)? Providing the pixels without the lens geometry limits the utility of the RAW format for any technical workflow requiring sub-pixel geometric integrity.

I’ve found nothing about the waitlist, like when are there expected openings, how does an opening occur, and do I need to do anything else except join the waitlist? It’s been indexing for the same amount of time that I’ve been waiting for Siri, so is that a factor?

Hello, After adapting Liquid Glass for iOS 26.5, I encountered an issue: the leftBarButtonItem(s) shift right, leaving a large space on the left after launching and dismissing the camera. I tried adding a negative spacer and setting leading space, but neither worked. This only happens when launching the camera; it does not occur during photo selection.

Environment: MacBook Air M4 macOS 27 Golden Gate Beta Xcode 27 Beta iPhone running iOS 27 Beta Apple Watch paired to the iPhone Steps to Reproduce: Install macOS 27 Beta and Xcode 27 Beta. Pair an Apple Watch with an iPhone running iOS 27 Beta. Enable Developer Mode on the iPhone. Connect the iPhone to the Mac and launch Xcode. Open Window → Devices and Simulators. Attempt to locate the paired Apple Watch or enable Developer Mode on the watch. Expected Result: The paired Apple Watch appears in Xcode for development purposes. A Developer Mode option is available on the Apple Watch. Xcode is able to recognize and communicate with the watch through the paired iPhone. Actual Result: The Apple Watch does not appear in Xcode. No Developer Mode option is visible on the watch. The iPhone is successfully paired and running iOS 27 Beta, but the watch remains unavailable for development workflows. Additional Notes: The iPhone and Apple Watch are already paired and functioning normally. Developer Mode is enabled on the iPhone. Restarting devices and reconnecting the iPhone did not resolve the issue. Unsure whether this is a limitation of the current beta builds or a regression in Xcode/watchOS development tooling.

If some Siri AI features work on cloud why not for older device? Apple Devs mentioned that the Siri AI is available for iPhone 15 and later devices and we can use iCloud+ Subscription to use it more on Apple’s Private Cloud Compute (PCC). So if it can run some functions on Private Cloud why not for people with older device? Or will Apple make it compatible with older devices on upcoming beta updates? Also, I noticed that other Phone companies have these features in phones that are way less powerful than iPhone 11 (Which is a oldest device support iOS 27) I tested some ai models from 3rd party apps that are less than 300MB and it worked very well than the old siri so can We add some Siri features to older iPhone? So we can avoid people from switching to other phones. Because I don’t want my friends leaving iPhone.

I’m seeing a Bluetooth call audio routing issue on a new iPhone 17 Pro running iOS 26.5.1, build 23F81. Bluetooth media audio works normally. Music and video audio stay on Bluetooth headphones without issues. The problem appears only when the device switches into call audio / HFP mode. Tested with multiple earbuds: Samsung, OPPO, Huawei and CMF Buds Pro 2. The behavior is similar with all of them. There are no other Bluetooth devices connected. Call Audio Routing is already set to Bluetooth Headset in Accessibility settings. The issue affects cellular calls, FaceTime Audio, Telegram and Signal. In some cases the earbuds seem to switch into call mode, but the call audio route falls back to the iPhone receiver or speaker instead of staying on the Bluetooth headset. After the call ends, Bluetooth media audio returns normally. I captured a sysdiagnose right after reproducing the issue. Relevant observations from the logs: Device: iPhone18,2 iOS: 26.5.1 Build: 23F81 Sysdiagnose time: 2026-06-03 11:22:03 +0300 In Bluetooth/CoreCapture/bluetooth_status.txt, Bluetooth was ON 3 paired devices were present 1 device was connected Connected device at the time: CMF Buds Pro 2 So the headset was not simply disconnected from the phone. In the powerlog, before the call the audio route was HeadphonesBT for media playback. Around the FaceTime Audio test, HeadsetBT / PhoneCall appeared, but then the route moved to ReceiverAndMicrophone / Speaker instead of staying on HeadsetBT. During a later cellular call, the active PhoneCall route was also ReceiverAndMicrophone rather than HeadsetBT. After the call ended, the route returned to HeadphonesBT for media playback. This looks like the Bluetooth connection remains alive, but call audio / HFP routing fails. The same sysdiagnose also contains CentauriFirmwareEvent entries under crashes_and_spins from the previous day. They show: subsystem = BT host-reason = firmware crash BTMAIN panic faulting_task = link_manager_thread LMAC_5G watchdog expired SCAN watchdog expired These firmware crash events do not happen at the exact same timestamp as the call test, so I’m not claiming that every call directly crashes Bluetooth firmware. But the sysdiagnose shows both incorrect Bluetooth call audio routing and separate BT firmware crash events. Has anyone seen similar behavior on iPhone 17 / iOS 26 with Bluetooth HFP call audio? Could this be a known iOS 26 / Apple N1 / Bluetooth firmware issue, or does it look more like a hardware defect of this particular device?

Hi there, Hope you are all well. I would like to know on how I am able to develop/build for both current software, like iOS 26 and iOS 27 at the same time. If it is possible, please let me know how. This is also my first WWDC as a developer, so I may have many questions. Sorry in advance lol. Thanks, Jason

We've 10 CoreML models in our app, each encrypted with a separate key generated in XCode. After opening and closing the app 6-7 times, the app crashes at model initialization with error: 2021-04-21 13:52:47.711729+0300 MyApp[95443:7341643] Fatal error: 'try!' expression unexpectedly raised an error: Error Domain=com.apple.CoreML Code=9 "Failed to generate key request for 08494FB2-B070-440F-A8A5-CBD0823A258E with error: -42905" UserInfo={NSLocalizedDescription=Failed to generate key request for 08494FB2-B070-440F-A8A5-CBD0823A258E with error: -42905}: file MyApp/Model.swift, line 43 Looks like iPhone is blocking the app for suspicious behavior and the app fails to decrypt the model. We noticed that after ~10 hours the app is unlocked, it successfully decrypts and initializes the model. Opening and closing the app many times in a short period of time is indeed unnatural, but the most important question is how to avoid blocking? Would Apple block the app if a user opens and closes it 10 times during a day? How does the number of models in the app affect probability that the app will be blocked? Thanks!

Our organization is attempting to retrieve the External Version Identifier (EVID) history for all published versions. This data is required so that we can pass the exact externalVersionIdentifier integer to our deployment framework to pin specific app versions on our managed devices. We currently have an active App Store Connect account, but our attempts to fetch this data via standard publishing APIs return a 401 Unauthorized error. To help us resolve this technical blocker, please provide explicit engineering guidance on the following four points: API Endpoint Architecture: Is the enterprise Apps and Books for Organizations API (apple.com) the only platform that exposes the externalVersionId history for all versions? If so, what is the exact endpoint path we must call to return the full version-based EVID array? Account Requirements: Can these version-specific EVIDs be retrieved using our existing App Store Connect developer credentials, or is an Apple Business Manager (ABM) account strictly mandatory to bypass the 401 gate? ABM Portal Setup for EVIDs Only: If an ABM account is mandatory, what are the minimum technical steps required inside the ABM dashboard to fetch only the EVID data? Specifically, do we need to "purchase" a volume license for the target app to make its version history accessible via the API? Authentication Parameters: What is the correct token structure for this endpoint? Do we need to pass a specific location server token (sToken / itvt cookie) generated inside ABM alongside our signed developer JWT header? Thank you for your time and technical guidance. We look forward to your engineering team's response.

I’m seeing a reproducible system-level Camera crash/termination on iPhone Air running iOS 26.4.2. Steps to reproduce: Press Camera Control to launch the Camera app. Tap the lower-left thumbnail to enter the recent photo view. Browse photos, or tap Edit and start cropping a photo. The Camera/Photos flow unexpectedly exits and returns to the Home Screen or widget view. Additional detail: The issue can happen whether or not a new photo is taken after launching Camera with Camera Control. In other words, using Camera Control as a shortcut into Camera, then tapping the lower-left thumbnail to browse photos, can trigger the issue. Sometimes it happens while only browsing photos, without entering Edit. Expected result: The photo viewer/editor should stay open and allow normal browsing or cropping. Actual result: The flow exits unexpectedly. Mac Console evidence: Around 2026-05-12 21:53:59-21:54:00, Console showed SpringBoard/RunningBoard terminating com.apple.camera. Relevant log excerpt: Capture Application Requirements Unmet: "AVCaptureEventInteraction not installed" reportType: CrashLog ReportCrash Parsing corpse data for pid 94087 com.apple.camera: Foreground: false Storage is sufficient. Restart/reset-style support steps have already been tried and did not resolve the issue. This appears specific to the Camera Control launch path, not normal Photos app browsing. Has anyone else seen this on iOS 26.x, or is this a known Camera Control / AVCaptureEventInteraction regression? Already Filed as FB22766094.

Hi, I'm looking for some clarity around hardware implementation details for the Iphone 17 Pro / Pro Max's camera sync via SMPTE ST2139. Question 1 (Signaling) ST2139 specifies that on the USB connector, D+ (pin A6 and B6), D- (pin A7 and B7) SBU1 (A8) and SBU2 (B8) can be used for sync signals. Does the iphone 17 pro / pro-max support all of these per the standard, or only a subset of these pins for sync signaling? Question 2 (Frame rates) Does the Iphone 17 pro / pro-max support ST2139 sync at any / all of its video rates (24, 25, 30, 60, 100, 120 fps), or only a subset of those? Question 3 (Sync tolerances) What is the tolerance of these rates to sync variation (ie would the phone/camera accept 29.970 sync when the camera is set to 30 fps?) and what are the tolerances for jitter to maintain a good sync lock? Thanks

My project uses the UINavigationController's largeTitle on the latest iOS 26.1, but I found that when I set the backgroundColor, the navigation bar's largeTitle disappeared after switching between normal and large titles. I checked the latest documentation and consulted AI, but I have not found any good solutions. For the demo project, please refer to FB20986869

Hello Apple Developer Community, I'm seeing a persistent crash in my iOS app reported via Firebase Crashlytics. The issue only started appearing on devices running iOS 26.3.0 and above (the crash does not occur on lower iOS versions, and it's unrelated to my app's version number). Key points: My app does NOT use any Text-to-Speech (TTS) features whatsoever. No AVSpeechSynthesizer, no Speech framework, no related APIs called from our code. My app is primarily written in Objective-C (with some Swift components possibly via dependencies). The crash stack is entirely within Apple's private TextToSpeech framework, specifically in ausdk::BufferAllocator::instance(). I suspect it might be indirectly triggered by a third-party ad SDK (e.g., Google Mobile Ads, AppLovin, etc.) that could be loading or interacting with accessibility features in the background — but this is just a hypothesis, as I have no direct evidence yet. Here is one representative crash log: Crashed: com.apple.root.user-initiated-qos.cooperative 0 TextToSpeech 0x6bb00 ausdk::BufferAllocator::instance() + 99800 1 TextToSpeech 0xf8c60 ausdk::BufferAllocator::instance() + 677688 2 TextToSpeech 0xf8c60 ausdk::BufferAllocator::instance() + 677688 3 TextToSpeech 0x1a0b9c ausdk::BufferAllocator::instance() + 1365620 4 libswift_Concurrency.dylib 0x628b4 swift::runJobInEstablishedExecutorContext(swift::Job*) + 288 5 libswift_Concurrency.dylib 0x63d28 swift_job_runImpl(swift::Job*, swift::SerialExecutorRef) + 156 6 libdispatch.dylib 0x13f48 _dispatch_root_queue_drain + 364 7 libdispatch.dylib 0x146fc _dispatch_worker_thread2 + 180 8 libsystem_pthread.dylib 0x137c _pthread_wqthread + 232 9 libsystem_pthread.dylib 0x8c0 start_wqthread + 8 The crash occurs on a background cooperative queue (Swift Concurrency). Questions: Has anyone else seen crashes inside ausdk::BufferAllocator::instance() in TextToSpeech on iOS 26.3.0+ even without using TTS in their app? Could a third-party ad SDK be causing the TextToSpeech framework to load unexpectedly (e.g., via accessibility preloading)? Is this a known bug in iOS 26's Spoken Content / Speak Selection features? Any workarounds or fixes from Apple? Any insights, similar reports (especially from Objective-C based apps), or advice would be greatly appreciated! Thanks!

Is there a safeAreaInsets equivalent that only tracks system bars (tab bars, status bars, side bars, toolbars, and navigation bars) and is not affected by notches? I'm asking this because the iPadOS tab bar can appear either on the top, bottom, or left (modally or non-modally) in various configurations, including sidebarAdaptable and when the window size is small on iPadOS; the tab bar's frame is not really reliable in this case, and while the safe area insets works, it also includes the notches / rounded window corners...

I am having an issue where my builds are marked green and ready for testing, but when I go to install from TestFlight I get the following message: "Could not Install X App" "The requested app is not available or doesn't exist" I've tried troubleshooting with information found online, tried different testing users. New builds. All result in the same message. Multiple support emails to Apple Developer. No response in 8 days.

Hello, I'm experiencing a critical issue with my Flutter iOS app on TestFlight where the app shows a completely black screen immediately after launch. The app does NOT crash (no .ips logs in iOS Settings → Analytics & Improvements), but Flutter Engine appears not to start at all. The same code runs perfectly on Android.

After updating to Xcode 26 my XCUITests are now failing as during execution exceptions are being raised and caught by my catch all breakpoint These exceptions are only raised during testing, and seem to be referencing some private internal property. It happens when trying to tap a button based off an accessibilityIdentifier e.g. accessibilityIdentifier = "tertiary-button" ... ... app.buttons["tertiary-button"].tap() The full error is: Thread 1: "[<UIKit.ButtonBarButtonVisualProvider 0x600003b4aa00> valueForUndefinedKey:]: this class is not key value coding-compliant for the key _titleButton." Anyone found any workarounds or solutions? I need to get my tests running on the liquid glass UI

Hey everyone, Back in 2022 and 2023, we noticed that some images on our web pages would disappear randomly. After refreshing, some of the images that were missing would appear, but then another image would go missing. Did anyone else experience this issue? Is there a fix / workaround I can use? This only seems to be an issue on iOS devices and images that have the loading=“lazy” attribute.

Hello, I am working on a research project focused on creating accessible interactions for visually impaired users. I need to verify some automated assistance processes in a real-world usage environment where VoiceOver is enabled. However, I have encountered a blocking issue: When I connect the device through Xcode UI Test / WebDriverAgent (or Appium + WDA) and perform operations, VoiceOver gets interrupted (sometimes it is even directly turned off), preventing blind users from continuing to use the narrator. Replication steps (stable replication)    On iPhone, enable VoiceOver (Settings → Accessibility → Narrator), and keep the device unlocked and the screen on. On Mac, start [Xcode UI Test / WebDriverAgentRunner / Appium+WDA] and establish a session with the device (XCTest session). Perform any operation: read the accessibility tree (/source), take screenshots, or click/slide. Observe the phenomenon: VoiceOver will [automatically turn off / reading interruption / focus jumping / unable to continue reading the new interface]. Expected behavior VoiceOver, as the core accessibility capability, should remain running and be able to continue reading the interface; the automation/assistance process should not "steal" and cause the narrator to fail. Actual behavior VoiceOver is [turned off / interrupted], and even after interface changes, it cannot read normally, affecting the use of blind users. I would like to ask: Non-jailbroken or external hardware-free methods Is this a known limitation (such as the mutual exclusion between XCTest and VoiceOver as Accessibility clients)? Is there an officially supported way to allow the automation/assistance program to safely read necessary information and trigger operations while VoiceOver is enabled, without disrupting the narrator (such as App Intents, Shortcuts, or other API/framework suggestions)? If it is necessary to avoid XCTest/WDA: In the research prototype stage, what is the recommended "reproducible, measurable" alternative technical route?

On iOS 26 I’m seeing a small stutter when dismissing a SwiftUI .sheet with the swipe-down gesture. The same code was smooth on iOS 18. Has anyone else experienced this issue?
