Hey there Just updated to Xcode 26 on mac OS Sequoia (MBP M1 Max 32GB, 2021, so you know, still pretty decent and capable). Xcode is super slow on building, but also on editing. There is a lag between what I type and what is displayed. Am I the only one experiencing this? Is there something I should look into?

Xcode 26 (and previous versions) have these options: "Clean Build Folder…" vs "Clean Build Folder Immediately" (if you hold the option key). I can't tell how they're different. The ellipsis traditionally means you're going to get a dialog you have to address before the command will execute, but that doesn’t happen. Both seem to just delete files in the build folder.

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?

M4 Mac Mini: Xcode generates private keys with wrong label - codesigning impossible Background This is a follow up to my November 2024 thread "Keychain issues after installing backup on new Mac" which was closed because I had a temporary workaround. That workaround using my wife's MacBook Air for signing is not sustainable. I used AI assistance to determine the root cause. My DTS case 102877839447 is open but has not yet been forwarded to a DTS engineer. Environment Mac Mini M4, macOS 15.4.1 (Build 25E253) Xcode 26.4.1 (17E202) Team ID: Q23726668V (Computerade Products) Working comparison machine: MacBook Air, macOS 15.3 Precise Bug — Reproducible Every Time Every time Xcode generates a new certificate and key pair on my Mac Mini: Certificate: Apple Development: Michael Birch (9KD5TCGGHG) ✅ Private key: Apple Development: Michael Birch (Computerade Products) ❌ The key uses the organization name instead of the certificate identifier. They never pair as a valid codesigning identity. security find-identity -v -p codesigning always returns 0 valid identities. Cryptographic Evidence The internal application labels confirm the keys are cryptographically unrelated to their certificates: Key internal application label: 53C26EB056997276B5E938258D00665ACABD1F0F Certificate public key hash: 57cd1af4a9162f26b1a6d750e05a63a2166b75ff These do not match ❌ Confirmed Eliminated As Causes Keychain search list corruption — found and fixed Partition list — set correctly Access control — set to allow all applications Full Disk Access — granted to Xcode Xcode caches and preferences — completely cleared Login keychain — completely reset Orphaned certificates and keys — all removed SIP enabled, system fully up to date Valid P12 Import Also Fails A p12 exported from the working MacBook Air and cryptographically verified as a matched pair also fails on the Mac Mini: security import returns MAC verification failed Keychain Access import returns OSStatus -2 Importing certificate and key separately as PEM files succeeds but they are not recognized as a valid identity pair despite matching application labels A3F3F193B7896DA9055353F59AB450778CB09AE7 Question Is there a known issue with M4 Mac Mini keychain infrastructure where private keys are generated with incorrect internal application labels? Is there a lower level diagnostic or fix beyond what the security command provides? The problem is specific to my Mac Mini M4 and persisted thru more than a year of Mac OS and xCode updates.

Device Details: MBP M2 Pro AND MBP M3 Pro macOS 26.3 (25D125) Xcode Version 26.3, 26.2, 26.1 (I reinstalled all 3 of these after the macOS update) BUG: Xcode hangs indefinitely when performing Source Control operations (Pull or Push) on a Git repository that uses SSH authentication. The same repository works correctly when performing the equivalent Git operations from the Terminal using the Git CLI. The issue appears to be specific to Xcode’s internal Source Control integration. When the operation is triggered from Xcode, the UI shows a spinning progress indicator and never completes. Terminal Git commands (git fetch, git pull, git push) complete normally using the same SSH key and repository. A hang sample taken during the issue shows the Xcode main thread blocked in Source Control authentication and fingerprint handling code paths, including: IDESourceControlUIHandler IDESourceControlFingerprintManager handleAuthenticationFailure showFingerprintAlertOnWindow This suggests Xcode may be waiting on a Source Control authentication or host fingerprint UI flow that never resolves. SSH connectivity itself is functioning correctly: ssh -T git@bitbucket.org and ssh -T git@github.com both authenticate successfully. git ls-remote, git fetch, git pull, and git push all work correctly from Terminal. No Source Control accounts are configured in Xcode Preferences. Authentication relies entirely on SSH keys. Steps to Reproduce Configure an SSH key for Git access (e.g., Bitbucket or GitHub) and confirm it works via Terminal. Clone or open an existing Git repository that uses SSH (git@host:repo.git). Open the project/workspace in Xcode. In Xcode, attempt a Source Control operation such as: Source Control → Pull Source Control → Push Observe that Xcode displays a spinning progress indicator and does not complete the operation.

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?
