With the 27 OSes using UserDefaults.standard.integer(forKey: ) can cause a crash with EXC_BAD_ACCESS (code=1, address=0x0) It has been seen on a Multiplatform app, up to now tested on iOS/iPadOS and visionOS 27 Beta 1. In our code we use UserDefaults.standard.integer(forKey: ) from a singleton called during the SwiftUI app init(), and we don't know yet if this is the only moment there is a crash as we can't go farther. The API should return 0 if it can't get a value. There is no reason the app should crash if the API conforms to its contract. Running the same code from Xcode on iOS 26 runs it without issue.

This is not a minor visual glitch or a negligible beta bug; this is a catastrophic telecom and safety failure. In iOS 27 Developer Beta, attempting to activate Wi-Fi Calling for US carriers (like RedPocket, Mint, T-Mobile, etc.) that require an E911 address registration completely hard-crashes the Settings app. You cannot activate Wi-Fi Calling, you cannot register your emergency address, and your cellular service is effectively crippled. As an SRE, I pulled the Console logs and traced the crash. It is absolutely unacceptable that Apple is still relying on the ancient, long-deprecated ⁠UIWebBrowserView⁠ inside ⁠TPSCloudCallingWebViewController⁠ for a critical emergency service configuration page. The Settings app is dying from a dual-concurrency crash caused by aggressive iOS 27 refactoring colliding with this legacy web container: The Apple Intelligence / TextInputUI Collision: On page load, the new text prediction engine blindly scans the legacy web input fields and throws a fatal exception: ⁠-[UIThreadSafeNode _smartReplyUpdateInProgress]: unrecognized selector sent to instance⁠. The old web node simply doesn't support the new Smart Reply APIs. The WebKit Thread Violation: This input system failure (⁠RTIInputSystemClient⁠ invalidation) cascades into a complete WebKit thread deadlock. The engine attempts to parse the carrier's CSS and throws a fatal UIKit assertion: ⁠Modifying properties of a view's layer off the main thread is not allowed⁠. The OS instantly sends a ⁠SIGABRT⁠ to ⁠com.apple.Preferences⁠. I have tried every possible workaround: Disabling JavaScript, removing 3rd-party/foreign keyboards, turning off predictive text, and even using MITM proxies to strip the CSS from the carrier's gateway. Nothing works. The crash happens instantly on load because the TextInputUI injection and the background-thread layer mutation are hardcoded into the OS framework. It is utterly absurd that a broken Smart Reply UI prediction path can block a user from registering an emergency 911 address and activating their phone service. Apple, you need to fix this immediately. Either rewrite ⁠TPSCloudCallingWebViewController⁠ to use a modern ⁠WKWebView⁠, or patch ⁠TextInputUI⁠ to gracefully handle legacy ⁠UIThreadSafeNode⁠ instances. Do not ship another beta with a broken carrier service page.

I am experiencing random Wi-Fi and Bluetooth disconnections while using iOS 27. Both Wi-Fi and Bluetooth disconnect unexpectedly, then reconnect automatically a few seconds later. I have seen many similar reports on Reddit, so this does not seem to be an isolated issue. I have already submitted a report through Feedback Assistant with the feedback ID FB23121586. I hope this issue can be fixed soon, because it is really stressful when playing online games on my iPhone and worrying that the connection might suddenly drop. :(

Overview On Xcode 27, when trying to run on a specific destination, the option to “Clear Recent” is missing. This was available in Xcode 26. Manage Devices option exists, but this is to permanently add / remove destinations, this is different from “Clear Recent”. Please bring back “Clear Recent” (from Xcode 26 to Xcode 27) option to Xcode as it is very useful Environment: macOS 26.5.1 (25F80) Xcode 27.0 beta (27A5194q) Feedback FB23055381

Hi, I have listed below the Feedbacks for Xcode 27, please have a look at it, considerable time was spent on filing these feedbacks, thanks!

I have two lines through Verizon wireless, my main line for the account was acting like a dead eSIM every time it is on it kills my data completely even on the second phone line unable to send a receive phone calls, send a receive text messages, retrieve voicemails, or use data in any capacity from that line. I have completely deleted and reinstalled and reactivated eSIM for that line a handful of times in the last week/week and a half & it is the main account line being rendered completely unusabl.

Hi everyone, I am currently completely blocked from submitting my new app for TestFlight Beta Review (External Testing). The App Store Connect web interface fails to submit, and when I try to bypass the UI using the App Store Connect REST API to create a betaAppReviewSubmissions request, Apple's servers return the following 422 error: { "errors" : [ { "status" : "422", "code" : "ENTITY_UNPROCESSABLE.BETA_CONTRACT_MISSING", "title" : "Beta contract is missing for the app.", "detail" : "Beta Contract is missing." } ] } Here is what I have already checked and verified on my end: Agreements, Tax, and Banking: My "Paid Apps Agreement", "Free Apps Agreement", "U.S. Tax Forms", and "Bank Accounts" all clearly show as "Active" status. There are absolutely no pending banners or unaccepted agreements on developer.apple.com or appstoreconnect.apple.com. Apple Developer App: I logged into the official iOS Apple Developer app with the Account Holder ID, and there are no hidden agreements to accept there either. App Privacy: All data collection questions are answered, and the App Privacy section is fully Published. Test Information: All required Beta App Review details (Name, Email, Phone) are correctly filled. Export Compliance: My Info.plist includes <key>ITSAppUsesNonExemptEncryption</key><false/>, and the build attributes confirm it. It appears that my TestFlight beta contract has somehow become detached, bugged, or failed to provision on Apple's backend. Has anyone experienced this specific API error recently? Is there a way to force the system to re-provision the contract, or does this strictly require manual intervention from an Apple Engineer? Any guidance would be highly appreciated. Thanks!

Device: iPhone 17 Pro iOS Version: iOS 27 beta Problem Description I am experiencing the following issues on iOS 27 Beta: Bluetooth randomly turns off and on automatically • Bluetooth occasionally turns off by itself for a few seconds and then turns back on. • The issue is especially severe when connected to AirPods Pro 2 (latest beta firmware), but it also occurs even without AirPods connected. • It usually only starts happening frequently after the iPhone has been powered on for a long time. Restarting the device temporarily resolves it. 2. Network Connection Issues • Network frequently experiences lag and slow speeds. • The problem becomes particularly noticeable when cellular data is throttled to 1 Mbps. • Even when multiple strong Wi-Fi signals are available, the device often ignores them and continues using or automatically switches back to cellular data (relatively frequent intermittent issue). 3. Feedback Assistant completely broken • Trying to submit feedback through the Feedback Assistant app delay fails with the following error: 开始反馈时出错 请稍后再试。

I'm trying to start using Xcode Cloud from a project, but the only thing I get is the message saying "Failed to create workflow" with the actual error being "Could not find item. Domain: XcodeCloudKit.XcodeCloudCommandHandler.CommandHandlerError Code: 5". Initially, it did lead me to configuring permissions on GitHub. But it failed in the end probably because the git remote of the project was pointing to another organisation, that transferred the ownership to me. I switched remote to my org, but it didn't help. So, I revoked the permission and deleted Xcode Cloud app from my GitHub in hopes that the config process would start again. It does not. All I get is this senseless error. Is Xcode Cloud functionality functioning at all in Xcode beta 27 for anyone?

https://support.apple.com/en-us/126655 As stated in the “Prepare your network environment for stricter security requirements.” my understanding is that additional security requirements will be introduced from OS 27 onward and that we need to prepare for them. However, I understand that the content on this page is mainly about distributing apps and operating the app itself. For example, I believe that simply accessing a web page within the app, or conducting HTTP communications with servers unaffiliated with Apple, will remain possible as before. Is my understanding correct?

I had recently updated my mac to beta 27.0, but regular Xcode isn't supported on this beta version. So, I downloaded Xcode Beta from Apple Developer. Now when I'm trying to deploy an app for AppStore review, it is prompting me that beta builds can't upload an app. Is there any fix that I can again use normal Xcode in my mac ?

My phone no longer shows the waitlist for Siri and has the option to "Try New Siri." I select it, continue, continue and the settings change to "Siri (Beta)" and the waitlist option is no longer there, but when using Siri it's the old pre-Apple Intelligence Siri that activates (little bubble at the bottom) and it does not work. Going to Safari and typing "Siri://" opens the New Siri App, but it says "Siri Update in Progress; Adding support for Siri hasn't completed. Open Settings to check the status." The app does not show up in Spotlight. My phone is done Indexing and all signs point to my phone being enrolled to use the New Siri, but it isn't working at all and still has not shown up. I've tried restarting a few times. Anyone experiencing this too?

I'm trying to install Mac OS 27 on my Mac Book Pro m1 pro and I'm getting this error: I have tried from the terminal, clearing the cache, and I've tried a couple of different days and the issue still occurs. Internet connection if fine, no VPNs and nothing that should block it.

On earlier iOS versions Live Activity displays correctly according to mode set.  Can't find an opened issue for that version: iOS 26 device: iPhone 16

Hi everyone, My TestFlight build has been stuck in 'Waiting for Review' for over 32 hours and I'm hoping someone can help or share their experience. The situation: I have an External Testing group with a Public Link set up. The build was submitted for Beta App Review on March 19th but it's been over 32 hours with no update. I have 25+ testers waiting to install the app. What I've tried: Waited patiently Checked App Store Connect multiple times No rejection emails received No issues flagged by Apple Questions: Is anyone else experiencing unusually long review times for TestFlight external builds right now? Is there anything I can do to speed up the process or check if something is wrong? Has anyone successfully resolved this by contacting Apple Developer Support directly? Any advice would be greatly appreciated. Thank you! Apple Support Case ID: 102846633409

I am seeing serious issues with iPhone Mirroring on macOS 27 Developer Beta 1. Environment Mac: MacBook Pro, Apple M4 Pro Model: Mac16,7 RAM: 24 GB macOS: macOS 27.0 Developer Beta 1 Build: 26A5353q SIP: Enabled Developer Mode: Enabled iPhone: iPhone 15 Pro Max Previously tested on: iOS 27 Beta 1 Currently restored to: iOS 26.5 Issue 1: iPhone Mirroring does not connect on iOS 27 Beta 1 and can leave the iPhone unusable When my iPhone 15 Pro Max was running iOS 27 Beta 1, iPhone Mirroring on macOS 27 Developer Beta 1 did not connect properly. I tried connecting multiple times. The iPhone appeared to think that the mirroring session had started successfully, because the iPhone screen turned off as expected for iPhone Mirroring. However, the Mac never actually completed the connection and never displayed the mirrored iPhone session. After this happened, the iPhone became completely stuck and unresponsive. The phone did not respond normally, and even force restart attempts were not working. The device remained unusable until the battery fully drained, which took about two days. After the battery was fully depleted, I was able to put the iPhone into DFU mode and restore it back to iOS 26.5. This suggests that something may be broken in the iPhone Mirroring / Continuity connection state between macOS 27 Developer Beta 1 and iOS 27 Beta 1. The iPhone seems to enter a state where it believes it is connected for mirroring, while the Mac never actually establishes the session. Issue 2: iPhone Mirroring crashes on macOS 27 Developer Beta 1 when used with iOS 26.5 After restoring the iPhone 15 Pro Max back to iOS 26.5, I was able to get a crash report from the Mac side. The iPhone Mirroring app crashed on macOS 27 Developer Beta 1 with the following details: Process: iPhone Mirroring Identifier: com.apple.ScreenContinuity Version: 2.0 Build Version: 114.38.15.1 OS Version: macOS 27.0 (26A5353q) Hardware Model: Mac16,7 Exception Type: EXC_BREAKPOINT (SIGTRAP) Termination Reason: Namespace SIGNAL, Code 5, Trace/BPT trap: 5 Triggered by Thread: 2 Dispatch Queue: com.apple.root.user-initiated-qos.cooperative The crashed thread shows a Swift assertion failure inside ScreenSharingKit.framework: Thread 2 Crashed: 0 libswiftCore.dylib assertionFailure(:_:file:line:flags:) + 216 1 ScreenSharingKit 0x29fbb60e0 2 libswiftCore.dylib _swift_release_dealloc + 64 3 libswiftCore.dylib RefCounts::doDecrementSlow 4 ScreenSharingKit 0x29fa894c0 5 ScreenSharingKit 0x29fb484d8 6 ScreenSharingKit 0x29fb48614 ... 15 libswift_Concurrency.dylib completeTaskWithClosure Relevant binary image: /System/Library/PrivateFrameworks/ScreenSharingKit.framework/Versions/A/ScreenSharingKit CFBundleIdentifier: com.apple.screensharing.ScreenSharingKit CFBundleVersion: 114.38.15.1 Crash interpretation The crash appears to be a first-party Apple framework crash inside ScreenSharingKit, caused by a Swift assertion failure. It does not appear to be caused by memory pressure, Rosetta, or third-party code injection. Relevant crash report details: External Modification Summary: task_for_pid: 0 thread_create: 0 thread_set_state: 0 System Integrity Protection: enabled Memory usage also does not look excessive: Writable regions: Total=251.0M MALLOC: 128.4M Expected behavior iPhone Mirroring should either connect successfully or fail gracefully. It should not: Leave the iPhone in a stuck/unresponsive state. Put the iPhone screen into mirroring mode while the Mac never completes the connection. Require the iPhone battery to fully drain before DFU restore is possible. Crash on macOS with an internal ScreenSharingKit Swift assertion failure. Actual behavior On iOS 27 Beta 1: iPhone Mirroring never completed the connection on the Mac. The iPhone behaved as if the session started. The iPhone screen turned off. The iPhone became completely unresponsive. Force restart did not work. Device only became recoverable after battery fully drained. I then restored the iPhone to iOS 26.5 via DFU. On iOS 26.5: iPhone Mirroring was able to run, but the Mac-side app later crashed. The crash occurred inside Apple’s ScreenSharingKit.framework. The crash type was EXC_BREAKPOINT (SIGTRAP) from Swift _assertionFailure. Reproducibility Partially reproducible. iOS 27 Beta 1 + macOS 27 Developer Beta 1: connection repeatedly failed and eventually left the iPhone stuck. iOS 26.5 + macOS 27 Developer Beta 1: iPhone Mirroring can connect, but the Mac app crashed with the attached report. Crash identifiers Incident Identifier: B6D4D86D-03C4-4466-B9D6-4CF70DF0B46F Crash Reporter Key: 8BD85D40-8AC8-E771-2D80-153D7C4C5366 Process: iPhone Mirroring [11429] Bundle ID: com.apple.ScreenContinuity The crash report points to ScreenSharingKit.framework, so this looks like a possible beta regression in the iPhone Mirroring / Continuity stack.
