I am trying to create a test case in XCTest using the UI Test target. I have a use case where I use a SwiftUI Canvas to draw a network graph; and the user can drag the graph on the Canvas. After the drag, the user may click on a node. The application presents a popup with the information about the network node clicked. SwiftUI provides the information required for the application to translate the location of the tap into the original location prior to the drag; and so the logic behind the popup can determine which node the network graph was tapped by the user. It appears that the distance of the drag operation performed does not match distance that the image actually moved. The drag distance is always larger than the actual distance dragged. I can observe this during the test execution. The arrow starts at the correct spot but then goes further than the object being dragged. I also observe this when I am driving the application. Is there some standard and supported way to determine the distance that the image on the screen was moved given a specific distance of the "thenDragTo:" coordinate?

I enter the following example code into the chat screen, the code is applied, but the Undo button does not appear. The Undo button is also grayed out in the Edit menu. I don't know if this is due to the update or a settings issue, as this is my first time using Xcode. Before the update, there were no problems; the Undo button would appear right next to the chat screen after the code was applied, but now it's gone. Can you help me with this? Edit only: MetalPortfolio/MetalPortfolio/Models/Transaction.swift Goal: Make Transaction decoding backward-compatible so older saved transactions do not fail to load when newer fields are missing. Critical rules: - Do not edit any other file. - Do not change Transaction stored property names. - Do not change encoding format. - Do not change UI. - Do not change storage/export/import logic yet. - Do not change calculations. - Keep existing behavior for valid current JSON. Implementation: In Transaction.init(from:), change only optional/backward-compatible decoding where safe. Required: - fee should decode with default 0 if missing: fee = try container.decodeIfPresent(Double.self, forKey: .fee) ?? 0 Optional if consistent with existing defaults: - unit can keep decodeIfPresent fallback. - currency can keep decodeIfPresent fallback. Do not make core required fields optional: - id - type - asset - quantity - price - date Return only: - which file changed - exact decoding behavior changed

After entering a commit message into the commit message field in the Xcode source control changes editor, it will clear any commit message that I entered if I go to another part of Xcode and open a file in the editor and then go back to the changes screen.

Hey all, the codex sign in isn't working for me in Agents. I am using the 26.5 release candidate version. It always says "Not Signed In". I have completed the Sign In process multiple times. Anyone else seeing this? I have filed Feedback FB22732574

My development work is paused as Xcode is now non-functional on my Macs. Loading any project into Xcode soon leads to a hang and Force Quit. The SDKs are listed as "status unavailable". No Simulators are available. I've tried previous versions of Xcode; removing everything and re-installing; installation from the Store and direct from the Apple Developer site. I've created a Feedback issue. This happens on both of my Mac minis. I'm running Tahoe 26.4 (25E246) on both.

Hi, we've getting error when we are building our app with Xcode 15 beta versions and Xcode 15.0 public release. ld: B/BL out of range 156662596 (max +/-128MB) to '' To fix this just add -ld64 to Other Linker Flags in Target.

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!

I am constantly reaching my daily ChatGPT limit and even though it's recommending that I log in, I already am. What can I do to fix this?

When signing in to GitHub.com in Xcode, it shows what scopes must be set when creating a personal access token. However, when signing into GitLab.com, it doesn't show what scopes should be selected.

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.

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.

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.

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?

Xcode 26.5 stucks on Localization Generating Comments: Running on macOS Tahoe 26.5 When this happens, Xcode does not add new keys, although enabled: The only (known) workaround is to restart Xcode. Same happened with Xcode 26.4, 26.4.1 on macOS 26.4.1.

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.

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?

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.

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. 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

I tried every possible but it just won't work on my device. The program runs well on the simulator by the way

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.
