I've suddenly started seeing hundreds of the same block of four error messages (see attached image) when running my app on my iOS device through Xcode. I've tried Cleaning the Build folder, but I keep seeing these messages in the console but can't find anything about them. Phone is running iOS 26.1. Xcode is at 16.4. Mac is on Sequoia 15.5. The app is primarily a MapKit SwiftUI based application. Messages below: Connection error: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.PerfPowerTelemetryClientRegistrationService was invalidated: Connection init failed at lookup with error 159 - Sandbox restriction."

We’ve encountered what appears to be a CoreML regression between macOS 26.0.1 and macOS 26.1 Beta. In macOS 26.0.1, CoreML models run and produce correct results. However, in macOS 26.1 Beta, the same models produce scrambled or corrupted outputs, suggesting that tensor memory is being read or written incorrectly. The behavior is consistent with a low-level stride or pointer arithmetic issue — for example, using 16-bit strides on 32-bit data or other mismatches in tensor layout handling. Reproduction Install ON1 Photo RAW 2026 or ON1 Resize 2026 on macOS 26.0.1. Use the newest Highest Quality resize model, which is Stable Diffusion–based and runs through CoreML. Observe correct, high-quality results. Upgrade to macOS 26.1 Beta and run the same operation again. The output becomes visually scrambled or corrupted. We are also seeing similar issues with another Stable Diffusion UNet model that previously worked correctly on macOS 26.0.1. This suggests the regression may affect multiple diffusion-style architectures, likely due to a change in CoreML’s tensor stride, layout computation, or memory alignment between these versions. Notes The affected models are exported using standard CoreML conversion pipelines. No custom operators or third-party CoreML runtime layers are used. The issue reproduces consistently across multiple machines. It would be helpful to know if there were changes to CoreML’s tensor layout, precision handling, or MLCompute backend between macOS 26.0.1 and 26.1 Beta, or if this is a known regression in the current beta.

It has been two years since I wrote my a SwiftUI app, and I wanted to start again in Xcode 26. I can no longer see the attributes inspector when I select an element in the canvas. This was an Xcode feature that was very helpful as I am still a novice. Has this feature been deprecated in Xcode 26? And if not, please help explain how I can find and use it.

After upgrading to macOS 26.0 Tahoe and Xcode 26.0.1, I’ve noticed an issue with audio playback whenever the iOS Simulator is running. Device: MacBook Pro 13" (2020, Intel, 16GB RAM, 500GB SSD) Issue: Any sound played on the Mac (system sounds, music, videos) begins to break/distort once the Simulator is active. App Sounds: If the app running inside the Simulator plays audio, that audio also breaks/distorts. Previous Version: This issue did not occur on macOS Sequoia 15 or with Xcode 16. Everything was working fine before the upgrade.

Hello, I recently applied for enrollment in the Apple Developer Program, and my application has been under review for some time (5 days now). I would appreciate any guidance or insight into the status or typical processing time. Here are my details: Full Name: Kingsley Ibok Enrollment ID: FX678S24XD Please what steps can I take now, I’d really appreciate Thank you.

It's a Broadcast Extension issue: on iOS 26.1 beta the extension never launches—after you tap “Start Broadcast” in the system picker the countdown disappears after 3 s and no broadcast starts, so every live-streaming app（and all other non-system apps that use Broadcast Extension） fails to go live (only the native Photos screen recording still works). Is this a known regression or is a new entitlement required?

I am writing to report multiple issues encountered after updating to Xcode 26 Beta, which have significantly impacted my project's compilation and functionality. My project can run normally in Xcode16.3 version, Below are the specific problems, along with the steps I took to address them and the subsequent errors that arose: Symbol Not Found Error for _NSUserActivityTypeBrowsingWeb After updating to Xcode 26 Beta, my project failed to build with the error: "Symbol not found: _NSUserActivityTypeBrowsingWeb." To resolve this, I removed the MobileCoreServices framework from the Build Settings, as it appeared to be related. However, this led to a new error, indicating that this change introduced further complications. Clang++ Error: No Such File or Directory 'OpenGLES' Following the resolution of the first issue, I encountered a new error: "iOS clang++: error: no such file or directory: 'OpenGLES'." To address this, I added the OpenGLES.framework to the Build Phases. While this resolved the clang++ error, it triggered additional errors, suggesting that the underlying issue persists or new dependencies are conflicting. Recurring XIB File Compilation Errors My project uses XIB files, and every time I attempt to compile and run, Xcode reports errors related to different XIB files. Notably, when I open the reported XIB file, no errors are displayed within the Interface Builder. After saving or inspecting the file, the compilation error temporarily disappears, only for another XIB file to trigger the same issue in the next build. This creates a repetitive cycle. I have confirmed this is not a caching issue, as I clean the build cache (Product > Clean Build Folder) before each run. If I skip cleaning the cache, the OpenGLES-related error (Issue 2) reappears, indicating potential interactions between these problems. These issues have made development with Xcode 26 Beta extremely challenging, as each attempted fix seems to introduce new errors, and the XIB issue creates a persistent loop. My setup includes: Xcode Version: 26.0 beta 2 (17A5241o) macOS Version:15.4.1 (24E263)

When I use Xcode 26 (0.1, 1) for debugging and hit a breakpoint, using "step over" causes the debugger to freeze at a random line of code. Clicking "Pause program execution" indicates that the line is being executed, but the breakpoint never exits, seemingly causing a freeze. The application on the simulator also becomes unresponsive. However, when I do not use breakpoints, my program runs smoothly, and debugging on a physical device does not cause any freezes. This issue only occurs with the simulator. I am using Xcode on Apple Silicon, and due to some third-party SDKs that depend on Rosetta, our app can only run on the Rosetta simulator. We did not encounter this issue when using Xcode 16.x for simulator debugging. The current situation with Xcode 26.x significantly reduces our development efficiency. What could be causing this, and is there a solution?

Xcode 16.3 build on ios18.4 ,app can't launch. Then lost connection to the debugger . but Xcode16.3 with ios18.3 can launch

I get a lot of downloads from outside USA but almost no conversion (subscription/IAP) from those countries. Apple App Store does the price conversion based on currency conversion and VAT but it does not take into account that $10 in India or Argentina is a much bigger portion of ones income compared to a US person. Converting all these prices (175 of them) manually is very cumbersome for each subscription tier and for each region.

Hello Using a MacBook Pro Intel with macOS 12.7.6 Monterey, I test in Objective-C an event for the option key but it is not working - (void)keyDown:(NSEvent *)event { printf("%s %p\n", __FUNCTION__, self); BOOL altFlag = [event modifierFlags] & NSEventModifierFlagOption; if (altFlag) { // UpdateClass printf("option pressed\n"); } else { printf("option not pressed\n"); } } The same in Swift works fine override func keyDown(with event: NSEvent) { if event.modifierFlags.contains(.option) { print("option pressed") } else { print("option NOT pressed") } } The Obj-C code works fine on a MacBook Air Tahoe 26.3 Any idea why it does not work on the macOS 12.7.6 Intel? Many Thanks Jean

The application crashes immediately when the system attempts to display the automatic password input view controller (_SFAutomaticPasswordInputViewController).

Following an unexpected error message while working in Xcode, the project file xcodeproj is no longer synced in iCloud Drive. The Finder shows a cloud icon with a ! and an error message : (NSFileProviderErrorDomain error -2005.) If the local file is zipped, and unzipped elsewhere on iCloud Drive, then the unzipped file can still not be iCloud Synced. Restoring the file from a Time Machine archive does not solve the issue. Apple Care Support finds that iCloud Drive is working fine except for this xcodeproj file and says the issue is Xcode related.

We started seeing an access issue today when attempting to go to the Xcode Cloud tab in App Store Connect. When you navigate to https://appstoreconnect.apple.com/teams/:teamId/apps/:appId/ci we're seeing the following message: The page you’re looking for can’t be found. The page you’re looking for does not exist, or you do not have permission to view it. I am the account holder so it shouldn't be a permissions issue. Is there an ongoing outage or problem in Xcode Cloud? And, if so, where can I monitor this accurately?

Hi there, I am new to Xcode26 and dragged my AppIcon.icon (created with Icon Composer) into the project. Then build failed with "Could not locate icontool". Could anyone point me to the cleanest way to solve this? Any help would be appreciated, thanks!

I have designed a new icon for my app/Tahoe in Icon Composer (launched from within Xcode)but I simply cannot get it to show up. The documentation for Icon Composer spends a lot of time describing how to design the icons but goes distressingly vague/silent on how one might use it. It suggests that I should drag the file to Xcode and it will guide me as to where to put it. The app continues to use the old (pre-Tahoe) icon. I don't get any change of behaviour and I don't know what to name the file. I assume that there are no other settings that I have to change. I can't find anything on the web or in Apple's documentation: maybe I'm missing something obvious! My app is a working NSDocument-based Cocoa project. Any suggestions please.
