CoreML fails to decrypt a model
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!

Xcode 26.3 Claude Agent — 401 Invalid Bearer Token on Intel Mac (FB22141224)
I've been investigating a persistent 401 Invalid Bearer Token error with Claude Agent in Xcode 26.3 on an Intel Core i9 Mac and wanted to share my findings here in case others are affected. ENVIRONMENT Hardware: Intel Core i9 (x86_64) Xcode: 26.3 (17C529) macOS: 26.3 (25D125) THE ISSUE Claude Agent fails with "Failed to authenticate. API Error: 401 - Invalid bearer token" on every prompt, despite the account showing as Signed In under Settings → Intelligence. The error persists after signing out and back in, and the token is confirmed valid and unexpired in Keychain. WHAT WORKS Claude Code in Terminal works perfectly on the same machine with the same credentials The basic Claude Sonnet 4.5 coding assistant in Xcode works fine Only Claude Agent is affected ROOT CAUSE HYPOTHESIS Xcode appears to be installing an ARM64 Claude binary on Intel Macs silently, with no warning or fallback. This binary likely fails to execute on x86_64 hardware and that failure is being misreported upstream as a 401 authentication error — which is why the error has nothing to do with the actual credentials. APPLE'S RESPONSE Feedback report FB22141224 was closed as 'Works as currently designed' with the explanation that Claude Agent requires the Neural Engine found on Apple Silicon. However, Claude Agent calls Anthropic's remote API over the network and performs no on-device AI processing — the Neural Engine is not involved. The fact that Claude Code works fine on this same Intel Mac with the same credentials demonstrates this clearly. WORKAROUND Using an Anthropic API key instead of OAuth resolves the issue but requires additional paid billing outside of an existing Claude.ai subscription. Has anyone else experienced this on either Intel or Apple Silicon? I'd be particularly interested to hear if Apple Silicon users are also affected, as the Developer Forums suggest this may not be limited to Intel Macs (thread/816369). Any input from Apple DTS engineers would be greatly appreciated.

Unable to use codex agent in xcode
Whilst using codex, I got an error "The data couldn’t be read because it isn’t in the correct format." I determined that I was no longer signed in. I went through the OAUTH chain opening a web browser and going through the login. However every time I do it, the account still shows "Not signed In" I am on 26.5. I also removed the codex from components and redownloaded it. That made no difference. Any one else having these issues? Claude is working.

Xcode: Error downloading App Store Connect crash reports
Hello, I’m encountering an issue retrieving crash reports from the AppStore Connect using Xcode 26.4.1 (17E202). I’m signed in with multiple Apple IDs, including the one required to fetch crashes. When I select the destination application and attempt to download crashes in Organizer, a small warning icon appears in the top right corner. Clicking on it displays the following error: "{AppleID email}" failed with error: There was a failure decoding response: (HTTP 500, 20364 bytes) The data couldn’t be read because it isn’t in the correct format.. I already tried to remove my account and sign in again multiple times and also restarted Xcode but nothing seems to work. I wonder whether this is some new bug introduced in the latest Xcode version or rather local issue on my machine. Any help appreciated.

Can DEVELOPER_DIR or xcode-select support Command Line Tools at custom paths?
I'm trying to manage multiple Command Line Tools versions side-by-side (e.g., 16.2 and 26.2). I renamed the CLT directory to /Library/Developer/CommandLineTools-26.2.0 and set: xcode-select -s /Library/Developer/CommandLineTools-26.2.0 or DEVELOPER_DIR=/Library/Developer/CommandLineTools-26.2.0 Both result in: c++: error: unable to find Xcode installation from active developer path "/Library/Developer/CommandLineTools-26.2.0" It appears CLT only works at the fixed path /Library/Developer/CommandLineTools, unlike Xcode which can be at any location. Is this by design? Is there a supported way to use multiple CLT versions in parallel, similar to how multiple Xcode versions can coexist?

Store Kit 2 iOS system purchase confirmation dialog not consistent.
I'm running into an issue where it appears the product transaction is being cached and not showing a new iOS system popup dialog to confirm the purchase. This is affecting testing, and I need a solution to have iOS issue a new purchase transaction every time. Here's what happens, I call the following which always succeeds. try await product.purchase(options: [.appAccountToken(appToken)]) I'm signed into a developer sandbox account with a resubscribe every 5 minutes. After cancelling a subscription, I attempt to resubscribe using the same code as above. Frequently, the code executes without iOS showing the popup system dialog to confirm the purchaser. After waiting a period of time, iOS then resets itself and allows me to purchase again. What I want is an option the forces the iOS system confirm purchase dialog to show up every time the code executes. How do I fix this? iOs 26.4.1, iPhone 17 Pro.

XCode Quick Help panel
I'm a big fan of keeping documentation in the code, so it appears at the point of use. Obviously, DocC and the Quick Help panel are a pretty important part of that strategy. Unfortunately, it only works randomly, so even if I've just build documentation (which should not even matter, the doc is just a cmd+click away), Quick Help stays blank, often even on system items like Label. It seems totally accidental, which makes it hard to make to reproduce. Sometimes an Xcode restart helps, sometimes not. Sometimes changing the editor display helps, sometimes not. Any tips on that?

StoreKit Config file Options Grayed Out
I have a question concerning Xcode version 26. Ever since I installed this version on my Mac, I have been experiencing issues with the StoreKit configuration file. The Simulated StoreKit Failures check boxes and selections are all grayed out. Once in a while, I see a pop-up stating "The document 'TaConfig.storekit' could not be autosaved. The file has been changed by another application. The pop-up Save as... points to where my config file is located, but the config file is grayed out. I thought maybe the directory where the file is located is write protected, but I have been able to save other files to the same directory. The Edit Scheme... -> Run -> Options has the StoreKit Configuration set for my file TaConfig.storekit. It feels like there is an option somewhere that I'm missing.

Workarounds for Xcode previews errors: Cannot preview in this file - Failed to Launch
I have started to have issues with SwiftUI previews of iOS apps with projects under the Documents folder. I have experimented that in Xcode 26.4 and I am still seeing it in 26.5. The error is: Cannot preview in this file. Failed to launch xyz.abc.TestApp Looking at the diagnostics, Xcode gets a permission denied error when trying to open /Users/me/Documents/path/to/TestApp/DerivedData/TestApp/Build/Intermediates.noindex/TestApp.build/Debug-iphonesimulator/TestApp.build/Objects-normal/arm64/ContentView.1.preview-thunk-launch.o Error details below. Note that I have set DerivedData folders relative to the projects' roots. Additional information: I get errors on freshly created iOS projects, just trying to preview the default ContentView. Xcode has full disk access set in System Preferences > Privacy & Security. I have cleaned build folders, deleted the simulators, Xcode itself, cleared various caches, restarted and reinstalled Xcode to no avail. Checking Editor > Canvas > Use Legacy Previews Execution did not fix it either. Apps run fine in Simulator. System info: macOS 26.4.1, Xcode 26.5 (17F42), MacBook Pro M1 and Mac Studio M2 Max. I have found two ways to fix the problem while keeping DerivedData relative to the project's root: create the project in some other “unprotected” directory (/Users/me/Developer in my case), or uncheck Editor > Canvas > Automatically Refresh Canvas. Either way makes previews work again.

Bug in the Agentic Coding chat box
Since a few days ago, I noticed that every time you go to the top of the text in the Agentic Coding chat box, if you keep pressing the up arrow, the current message is replaced by the previous one. It's like someone decided to allow users to use the arrows to navigate to previous conversations in the same context, but this means that you are constantly jumping to previous messages by accident. The "feature" is error prone, confusing, and extremely annoying. If someone knows of an option in setting to disable it, please let me know. I'm constantly making mistakes, wasting tokens, editing the wrong message, and making the conversation confusing by sending the wrong message to the agent.

When working with an Objective-C project in Xcode 26.5, I'm unable to establish outlet and action connections by dragging between XIB files and the corresponding .h header files.
When working with an Objective-C project in Xcode 26.5, I'm unable to establish outlet and action connections by dragging between XIB files and the corresponding .h header files. This drag-and-drop connection works perfectly after switching to Xcode 26.3.0. In addition, under Xcode 26.5, drag-and-drop linking works normally for projects using Swift files together with XIB files. The issue only occurs with Objective-C .h files and XIB files.

After enabling Enhaced Security the linker error Library 'c++polyfills' not found occurs (Simulator only)
After enabling Enhanced Security for an existing iOS project (mixed Objective-C / Swift) I get the linker error: Library 'c++polyfills' not found This happens when compiling for a simulator as run destination. Device builds (debug) or archiving a release build works. However I need to be able to test on a simulator... Xcode version is 26.4.1, Simulator uses iOS 26.4.1

Using Xcode with Claude Opus 4.7
Has anyone got Xcode working with Opus 4.7? I have Claude Code running 4.7, but Xcode insists on running 4.6. Even working with Claude to try to configure Xcode doesn't work. Apparently Xcode does something that prevents using Opus 4.7. Any reason for this? Xcode has a really nice integration, but I guess It's bak to Terminal and Claude Code if I want to use the better Model. Anyone else got this working?

Xcode 26 beta stricter codesign validation rejecting Flutter.framework
While testing Flutter applications on macOS 26 beta with Xcode 26 beta, iOS builds consistently fail during Flutter.framework codesigning with: "resource fork, Finder information, or similar detritus not allowed" Investigation suggests newer Xcode beta versions now reject additional extended attributes beyond com.apple.FinderInfo during codesigning. Flutter tooling currently removes only: xattr -r -d com.apple.FinderInfo Replacing it with: xattr -cr successfully resolves the issue. Environment: macOS 26.4.1 beta Xcode 26.4.1 beta Apple Silicon (ARM64) Flutter 3.41.9 Flutter issue: https://github.com/flutter/flutter/issues/186372 Apple Feedback Assistant report: FB22756923 Interested to know whether other developers on Xcode 26 beta are seeing similar stricter codesigning validation behavior.

Possibly related: SwiftUI preview not working in Xcode 26 when “Automatically Refresh Canvas” is enabled Xcode 13.2.1 - Simulator works, Preview doesn't Excerpt from diagnostics: | | [Remote] JITError | | | | ================================== | | | | | [Remote] CouldNotLoadInputObjectFile: Could not load object file during preview: /Users/me/Documents/TestApp/DerivedData/TestApp/Build/Intermediates.noindex/TestApp.build/Debug-iphonesimulator/TestApp.build/Objects-normal/arm64/ContentView.1.preview-thunk-launch.o | | | | | | path: /Users/me/Documents/TestApp/DerivedData/TestApp/Build/Intermediates.noindex/TestApp.build/Debug-iphonesimulator/TestApp.build/Objects-normal/arm64/ContentView.1.preview-thunk-launch.o | | | | | | ================================== | | | | | | | [Remote] XOJITError | | | | | | | | XOJITError: '/Users/me/Documents/TestApp/DerivedData/TestApp/Build/Intermediates.noindex/TestApp.build/Debug-iphonesimulator/TestApp.build/Objects-normal/arm64/ContentView.1.preview-thunk-launch.o': Operation not permitted

Why I can't test the app on my own device even if I signed it with a valid development certificate
I tried every possible but it just won't work on my device. The program runs well on the simulator by the way

Bug in the Agentic Coding chat box
Since a few days ago, I noticed that every time you go to the top of the text in the Agentic Coding chat box, if you keep pressing the up arrow, the current message is replaced by the previous one. It's like someone decided to allow users to use the arrows to navigate to previous conversations in the same context, but this means that you are constantly jumping to previous messages by accident. The "feature" is error prone, confusing, and extremely annoying. If someone knows of an option in setting to disable it, please let me know. I'm constantly making mistakes, wasting tokens, editing the wrong message, and making the conversation confusing by sending the wrong message to the agent.

When working with an Objective-C project in Xcode 26.5, I'm unable to establish outlet and action connections by dragging between XIB files and the corresponding .h header files.
When working with an Objective-C project in Xcode 26.5, I'm unable to establish outlet and action connections by dragging between XIB files and the corresponding .h header files. This drag-and-drop connection works perfectly after switching to Xcode 26.3.0. In addition, under Xcode 26.5, drag-and-drop linking works normally for projects using Swift files together with XIB files. The issue only occurs with Objective-C .h files and XIB files.

Sectigo Public Server Authentication CA DV R36?
When I submit an https web request I receive both of those funny errors.

After enabling Enhaced Security the linker error Library 'c++polyfills' not found occurs (Simulator only)
After enabling Enhanced Security for an existing iOS project (mixed Objective-C / Swift) I get the linker error: Library 'c++polyfills' not found This happens when compiling for a simulator as run destination. Device builds (debug) or archiving a release build works. However I need to be able to test on a simulator... Xcode version is 26.4.1, Simulator uses iOS 26.4.1

Using Xcode with Claude Opus 4.7
Has anyone got Xcode working with Opus 4.7? I have Claude Code running 4.7, but Xcode insists on running 4.6. Even working with Claude to try to configure Xcode doesn't work. Apparently Xcode does something that prevents using Opus 4.7. Any reason for this? Xcode has a really nice integration, but I guess It's bak to Terminal and Claude Code if I want to use the better Model. Anyone else got this working?

Xcode 26 beta stricter codesign validation rejecting Flutter.framework
While testing Flutter applications on macOS 26 beta with Xcode 26 beta, iOS builds consistently fail during Flutter.framework codesigning with: "resource fork, Finder information, or similar detritus not allowed" Investigation suggests newer Xcode beta versions now reject additional extended attributes beyond com.apple.FinderInfo during codesigning. Flutter tooling currently removes only: xattr -r -d com.apple.FinderInfo Replacing it with: xattr -cr successfully resolves the issue. Environment: macOS 26.4.1 beta Xcode 26.4.1 beta Apple Silicon (ARM64) Flutter 3.41.9 Flutter issue: https://github.com/flutter/flutter/issues/186372 Apple Feedback Assistant report: FB22756923 Interested to know whether other developers on Xcode 26 beta are seeing similar stricter codesigning validation behavior.
