I just downloaded and installed the final released Xcode 27.2, and it queued up, downloaded, and installed not one but two simulator SDKs. Why is that?

I’m blocked debugging a watchOS app on a physical Apple Watch. The iPhone connects to Xcode normally (wired), but the Watch either fails to connect with a tunnel timeout or disappears entirely from Xcode after I unpaired it inside Devices & Simulators. Environment Mac: macOS 26.x (Apple Silicon Mac) Xcode: 26.2 iPhone: iOS 26.1 Apple Watch Ultra: watchOS 26.2 (build 23S303) Connection: iPhone connected to Mac via USB (trusted). Watch paired to iPhone and working normally in the Watch app. Issue A (when Watch is visible in Xcode) In Xcode → Window → Devices and Simulators, the Watch shows up but is not usable and fails to connect. Error: “Previous preparation error: A connection to this device could not be established.” “Timed out while attempting to establish tunnel using negotiated network parameters.” In some attempts the Watch shows “Capacity: Unknown” / limited details, and then fails during preparation. Issue B (after unpairing Watch in Xcode only) I unpaired/removed the Watch in Xcode (Devices & Simulators). I did not unpair the Watch from the iPhone. Now: iPhone appears in Xcode and works normally for builds. Watch is still paired to the iPhone and works normally. Watch no longer appears anywhere in Xcode Devices & Simulators (no paired watch section, no watch run destination). What I’ve tried Reboots of Mac, iPhone, Watch (multiple times) Watch unlocked, awake; iPhone unlocked and close to Watch Verified Watch is paired and connected in iPhone Watch app Developer Mode enabled on iPhone and Watch Wi-Fi and Bluetooth ON (Mac/iPhone/Watch), tried toggling both Tried on home Wi-Fi and also with iPhone hotspot (same result) Resetting trust prompts / reconnecting iPhone via USB, re-trusting Mac Apple Watch: “Clear Trusted Computers” Xcode: removing/re-adding devices; clearing derived data; restarting Xcode Watch Developer networking test: Responsiveness = Medium (430 RPM) Questions 1. Is this a known issue/regression with Xcode 26.2 + watchOS 26.2 tunneling (CoreDevice / devicectl)? 2. Is there an Apple-supported way to force Xcode to re-discover a paired Watch after it was removed from Xcode Devices & Simulators (without unpairing the Watch from the iPhone)? 3. Any recommended logs or diagnostic steps I should collect (Console logs, sysdiagnose, specific Xcode/CoreDevice logs) to include in a Feedback report? If helpful, I can provide the full error text from Xcode’s Devices window and any logs you recommend. Thank you in advance,

Unfortunately Radar has been down for several hours tpday, so I figured I'd post here to see if anyone else is having the same issue. All of our Notarization and Stapling for our non-App Store apps is done via Terminal. It's generally worked pretty well for the past 12 months. But for the last 6 days, Notarization has been fine, but Stapling results in a NSURLErrorDomain Code=-1005 error ("The network connection was lost.") about 50% of the time. Needless to say this is getting to be pretty frustrating. I haven't noticed any hiccups with my Internet connection. Using Xcode 26.3 on Sequoia 15.8.2, and again doing everything on the command line. Anyone else seeing the same thing? Here's the most recent Stapling failure from a few minutes ago: error is Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."

I have the following setup: UIViewRepresentable with a UIView holding UIScrollView ImageView PKCanvasView this is in order to make it appear as if you are writing on a paper which you can zoom and scroll. The UIImageView is holding the paper image. The problem is if you draw some pen strokes at zoom level 1, then zoom in (say zoom level 2) as soon as you place down the pen, the PKCanvasView starts flickering repeatedly very badly. A sample video is here: https://youtube.com/shorts/5zeq6EDheSM a small sample project showing this is here: https://www.icloud.com/iclouddrive/0a0NSLP4bsism69L7jRtZPIhQ#BugDemo

Uploading an iOS app built with the public release of Xcode 27.2 (27B52) fails with this error (code 90534 / ITMS-90534 in the upload logs): Unsupported SDK or Xcode version. Your app was built with an SDK or version of Xcode that isn't supported. Although you can use beta versions of SDKs and Xcode to build and upload apps to App Store Connect, you need to use the latest Release Candidates (RC) for SDKs and Xcode to submit the app. For details on currently supported SDKs and versions of Xcode, visit: https://developer.apple.com/news/releases. The upload itself completes; the error is returned afterward by App Store Connect when Xcode checks the upload's status, so this looks like server-side validation not yet recognizing the final 27B52 build. As of today, developer.apple.com/news/releases lists Xcode 27.2 RC (27B48) but not Xcode 27.2 (27B52). Archive metadata (app and all extensions match): DTXcode: 2720 DTXcodeBuild: 27B52 DTSDKName: iphoneos27.2 DTSDKBuild: 24B8118 Deployment target: iOS 26.0 No embedded third-party frameworks Uploaded via Xcode Organizer (ContentDelivery 27.10.4-2.2), macOS 27.2 (26B123) Local setup checked: Only one Xcode installed (27.2, 27B52); xcode-select points to it; no DEVELOPER_DIR or SDKROOT overrides Reproduced after a clean build and a fresh archive Upload error IDs: JITIPJCXJDJFKY7RQZS6GAWAGM (Oct 30, 2026) 2D3BNQAYTYPEPADRSCS4XCHZME (Oct 30, 2026, after a clean rebuild) Can Apple confirm whether Xcode 27.2 (27B52) is accepted for App Store submission, or whether builds should use 27.2 RC (27B48) until it is?

FB22844728 Xcode 26.5, macOS 26.5, MacStudio M1 64 GB The disaster of S-L-O-W T-Y-P-I-N-G that plagued Xcode several years ago returns. I guess all the ultra-advanced LLM neuroneirowebs still can't advise those at Apple who develop the Xcode app how to provide this uber-exotic, unheard-of functionality: JUST TYPING THE CODE. This disaster doesn't affect all projects, but it does affect the exact one I'm working on, and I need to type a lot of code there. Significant time is already wasted. I performed all the recommended steps like relaunching, restarting, and deleting deprived data with no effect. Hope something can be done about it..

We are installing Xcode for standard users, but as the standard users don’t have admin rights, they cannot install the system wide components they need admin access to do that, but we don’t want to grant admin access to our users. We have already developed a script where we are accepting the license and we are doing the run first launch, but they still need the iOS simulator and the other packages pre-installed, so how can we do that?

SUMMARY In Xcode 27.1, opening any Main.storyboard never finishes loading. The editor shows "Loading iOS 27.1..." indefinitely. This happens in existing projects and in a brand-new iOS App project created with Interface: Storyboard. Before that, the editor showed "Failed to open Main.storyboard: iOS 27.1 Platform Not Installed." ENVIRONMENT Xcode 27.1 iOS SDK build: 24A94232 (from xcrun --sdk iphonesimulator --show-sdk-build-version) macOS: [YOUR macOS VERSION] Hardware: MacBook Air, Apple M1 Run destination: iPhone 17 Pro Max simulator STEPS TO REPRODUCE Open Xcode 27.1. Create a new project: iOS > App, Interface: Storyboard, Language: Swift. Click Main.storyboard in the Project Navigator. EXPECTED RESULT The storyboard renders in Interface Builder and the Objects library lists UI elements. ACTUAL RESULT The editor stays on "Loading iOS 27.1..." and the Objects library shows "No Matches." Opening the file as Source Code works, and the XML is valid (targetRuntime="iOS.CocoaTouch"), so the file itself is fine. RUNTIME STATE Initially the only iOS 27.1 runtime installed was build 24A94425, shown as Ready in xcrun simctl runtime list. Xcode reported "iOS 27.1 Platform Not Installed," and the runtime did not appear in Settings > Components. The Xcode SDK build is 24A94232, which does not match 24A94425. I ran xcodebuild -downloadPlatform iOS, which installed iOS 27.1 (24A94232). The error then changed to "Loading iOS 27.1..." and stayed there. Settings > Components then showed an "Update" button for iOS 27.1 (8.07 GB). Clicking it installed iOS 27.1 (24A94425) again, so both builds are now present and Ready. The storyboard is still stuck. WHAT I TRIED (none fixed it) Deleting ~/Library/Developer/Xcode/DerivedData sudo killall -9 com.apple.CoreSimulator.CoreSimulatorService Removing and reinstalling the iOS 27.1 runtime Restarting the Mac Waiting several minutes on the first load (~/Library/Developer/Xcode/UserData/IB Support does not exist on this machine) [link text](https://www.example.com/)

I have submitted a feedback report regarding Xcode 27.1 RC Device Hub: iPhone Duo screen captures function only work when the device is fully closed; alternative hinge positions produce a blank display.

This was maddening: I had written a very long and detailed prompt, then went to select "Codex" from the drop down menu at the top "start a new conversation", and it wiped out the entire prompt I was working on. Well, of course it did: that drop down is part of the "Start a new Conversation" icon button, but it's position is too far away from the actual icon to infer that is its purpose. It should be a popup that shows the current choice for model (GPT-5, GPT 4.1, Codex). ANOTHER lost prompt problem. If you have a prompt-in-progress (AI is maybe building some code), and Xcode crashes, it might not save that prompt for when you re-launch. And how might that happen? Well, there's still numerous ways using the coding assistanty might crash. One I've notice is if you switch out to another app, or if you invoke a screen capture, it might crash.

Does Xcode 27 or TestFlight support installing a watch-only beta on an Apple Watch For Your Kids device? I want to test my watch only standalone app on my kids apple watch as that is the only device I have. Is it possible to use that watch for testing standalone apple watch application. The watch is setup as kids watch on my iphone.

In a synthetic reproduction of a DeviceSupport-style backup on macOS 26.7.1 with Xcode 26.6 on Apple silicon, a source object has no com.apple.provenance, while a newly created destination object acquires that private extended attribute. File contents, modes, ACLs, and the source's other extended-attribute names can be verified independently. The backup acceptance contract requires a future restore to reproduce the original governed metadata. Is destination creation expected to add this attribute? For a faithful restore to a fresh APFS destination, should restoration software omit it, remove it after creation, preserve it, or allow macOS to regenerate it? Which supported API or documented postconditions establish restoration fidelity when the source lacked the attribute? Could the attribute affect DeviceSupport symbol usability or access behavior? We are seeking Apple-supported backup and restoration procedures and security postconditions, not an interpretation of private metadata. No real DeviceSupport files, raw private attribute values, production paths, credentials, datasets, or personal information are included.

Trying to delete or replace appIcon in my project's assets.xassets fails. After a few seconds xcode displays error "...couldn't be moved to the trash because the volume Macintosh HD doesn't have one." Needless to say the trash folder exists and works from Finder. The volume has 97G free space. I tried xcode's 'delete derived data' and 'clean build folder' and restarted xcode. Same behavior (deleting appIcon fails).

On Xcode 26 and earlier versions, two-finger touches were possible on Simulator by holding down the option key. On Xcode 27 with Device Hub, this is no longer possible. While the trackpad can be used for pinch and rotate gestures, two-finger taps and two-finger pans are not possible. This is a major regression that renders our app basically unusable in Device Hub. We rely on two-finger tap and pan gestures to navigate our 3D models. Not being able to do this in Device Hub and in Xcode previews would be a huge loss. Is this actually no longer supported or am I missing something?

I am qualifying a data-preserving update of my own development-signed iOS/iPadOS app (Target Keeper). I would like to understand the supported recovery guarantees and limitations before changing an existing installation, rather than treating a completed backup or successful model-open test as proof of full rollback. Environment: iOS/iPadOS 27.0.1 and Xcode 27.1. Existing development installations must be retained. The original signed packages for the older installed builds are unavailable. No update, uninstall, device erase or restore has been performed as part of this qualification. Evidence already retained privately: Completed encrypted Finder backup records for each device, with the password kept private. Apple Device Hub downloads of each existing app-data container, retained separately with file counts and SHA-256 manifests. Disposable copies of the actual prior SwiftData store, relevant WAL/SHM files, preferences and selected-photo data opened using the proposed version's existing model and guarded local-startup implementation. Model identities/content fingerprints were unchanged in those tests. The separate Codable Portfolio repository passed loading/reopening on disposable copies without changing the ledger bytes. Controlled process interruption/reopen tests passed on disposable local copies. These tests did not run the entire signed app-update lifecycle on a physical device, validate Keychain continuity, establish an atomic source-side multi-store snapshot, or test restore on the original devices. CloudKit records are not being mutated. I have read Apple's update-testing and container-download/replace guidance: https://developer.apple.com/documentation/xcode/testing-a-release-build https://help.apple.com/xcode/mac/current/en.lproj/dev816c242e1.html Specific questions: For a locally development-signed app that is not available from the App Store, what does an encrypted Finder backup preserve and what additional artifacts are needed to recover the usable app and its data if the original signed app package is missing? Does a backup completion record establish anything about restoration of that development executable? What consistency guarantees does Device Hub's app-container download provide when the app has multiple stores (SwiftData/SQLite with WAL, a separate JSON ledger, preferences and photos)? Is a quiescent/terminated app required, and what is the recommended way to qualify a coherent capture without modifying the original records? What is Apple's recommended recovery rehearsal on a disposable device/installation before an in-place update? Which identity, signing, file-protection and Keychain limitations must be considered, especially for ThisDeviceOnly items and same-device versus different-device restoration? Which preservation checks remain the developer's responsibility beyond successful container replacement or store opening? I do not want to mistake reinstalling an app binary for rolling back a migrated multi-store data set. Separately, an earlier strict source read rejected a file-metadata change, but its paired content hashes were not retained. I am not asserting an Apple defect, corruption or an identified writer, and newer successful copies cannot reconstruct that missing observation. Is there a recommended narrowly scoped Apple diagnostic for future capture that records before/after file identity and content consistency without weakening integrity rejection? No backups, passwords, personal device identifiers, private certificates, record contents or confidential logs are attached. I am seeking a supported qualification procedure, not instructions to bypass preservation safeguards or destructively test on the original devices.

Hello team, We are testing the Declared Age Range/Age Signal functionality in a TestFlight build and would appreciate guidance on the correct setup and testing process. Current Behavior Observed We are seeing inconsistent behavior between the Sandbox environment and the age-range results returned to the application. Scenario 1: Apple Account Signed In A regular Apple ID is signed in on the device. The TestFlight build is installed and launched. The application returns Verified Adult (18+). We then sign in to the Sandbox environment using a Sandbox Test Account and select a different test scenario (for example, a child/minor scenario). After relaunching the application, the age signal response still remains Verified Adult (18+). Scenario 2: Apple Account Signed Out We sign out of the Apple account from the device. As a result, TestFlight is also signed out. When the application is launched, the response changes to Unable to Verify. Even after changing Sandbox test scenarios (such as child, teen, or adult scenarios), the application continues to return Unable to Verify rather than the selected test case response. Based on this behavior, it appears that the application is not reflecting the scenario selected in the Sandbox environment. Questions What is the correct process for connecting an application to the Sandbox environment when testing Declared Age Range scenarios? Does the Apple ID used for TestFlight need to be associated with or match the Sandbox Test Account? Should the device remain signed in to a regular Apple ID while the Sandbox Test Account is used for testing? How does the app determine whether it should use the selected Sandbox scenario versus the signed-in Apple account? Are there any additional device settings, account requirements, or configuration steps required for Sandbox age-range testing? Is there a way to verify that the application is successfully connected to the Sandbox environment and consuming the selected test scenario? If the Sandbox scenario is configured correctly, should we expect the API response to change immediately when switching between child, teen, and adult test cases? At present, regardless of the Sandbox scenario selected, the application either continues to return Verified Adult (18+) or Unable to Verify, and we have been unable to validate the documented Sandbox test scenarios. Could you please provide guidance on the expected setup and testing workflow for TestFlight applications using the Declared Age Range feature? Thank you for your assistance.

Hello, I’m trying to pair an Apple Watch Ultra 4 running watchOS 27 with Xcode 27, but the watch does not appear in Device Hub or under “Pair Nearby Device”. The iPhone paired with the watch is detected correctly by Xcode. Developer Mode is enabled on both devices, and the Mac, iPhone, and Apple Watch are on the same Wi-Fi network. I have already tried restarting all devices, connecting the iPhone by USB, disabling and re-enabling Bluetooth and Wi-Fi, disabling VPN/firewall software, and checking that the watchOS Developer Disk Image is installed and usable. The watch still does not appear as a physical device. Only Apple Watch simulators are listed. Has anyone experienced this issue or found a workaround? Thank you.

Hi, xcodebuild -downloadPlatform iOS stays at "Preparing to download..." for the iOS 27.1 Simulator (24A94425). mobileassetd receives 0 bytes.

It has always been this way. But I wonder why? Having the minimal xcode project, if you building and archive with: xcodebuild archive -project sample.xcodeproj -scheme sample -configuration Release -destination 'generic/platform=macOS' -archivePath out/sample.xcarchive DWARF_DSYM_FOLDER_PATH='out/dsym'final xcarchive will have empty dSYMs directory. At the same time, out/dsym/sample.app.dSYM exists. So it turns out that dSYM generation respects DWARF_DSYM_FOLDER_PATH variable, but archiving operation - doesn't. From my point of view, this is not logical because I explicitly specified the location and this location works partially. Am I missing anything? Is there some other variables that controls where archiving searchs for dSYM? Because at this moment it looks like it is internally hardcoded to somewhat like "$(BUILD_DIR)/$(CONFIGURATION)" Any help is appreciated, Best regards!

I am using Coding Intelligence, powered by Claude, in the first production release of Xcode 27.0 (in MacOS 26.7). Initially it was working ok. But after less than a day, it now crashes every time it needs to ask for permission for any shell command. And each time I restart things, it burns through a ton of tokens. ☹️ Any suggestions? (I'll file a bug report right now…)
