Some Macs recently received a macOS system update which disabled the simulator runtimes used by Xcode 15, including the simulators for iOS, tvOS, watchOS, and visionOS. If your Mac received this update, you will receive the following error message and will be unable to use the simulator: The com.apple.CoreSimulator.SimRuntime.iOS-17-2 simulator runtime is not available. Domain: com.apple.CoreSimulator.SimError Code: 401 Failure Reason: runtime profile not found using "System" match policy Recovery Suggestion: Download the com.apple.CoreSimulator.SimRuntime.iOS-17-2 simulator runtime from the Xcode To resume using the simulator, please reboot your Mac. After rebooting, check Xcode Preferences → Platforms to ensure that the simulator runtime you would like to use is still installed. If it is missing, use the Get button to download it again. The Xcode 15.3 Release Notes are also updated with this information.

Intelligence AI powered feature fails on complex project with network error when “Reasoning” is set higher then “Low”. The visual feedback shows sending some context and answer being generated, but eventually stops with network error. Retries with “Reasoning” set higher than “Low”. won’t help, but retries or same queries with “Low” or "Minimal" reasoning always succeed. It is obvious that connectivity is not lost but looks like some kind of timeout expires and cancels the response, even not the request. Visual feedback shows the context being successfully uploaded and even shows the indicator of the answer being generated.

Hi all, I'm working on a Call Directory Extension using CXCallDirectoryExtensionContext. I want to add a list of numbers to be blocked. Here's the function I use: override func beginRequest(with context: CXCallDirectoryExtensionContext) { context.delegate = self let blockedNumbers = loadNumberEntries(forKey: blockedKey) let identifiedNumbers = loadNumberEntries(forKey: identifiedKey) addAllBlocking(blockedNumbers, to: context) addAllIdentification(identifiedNumbers, to: context) context.completeRequest() } private func addAllBlocking(_ entries: [NumberEntry], to context: CXCallDirectoryExtensionContext) { let numbers: [Int64] = entries.compactMap { Int64($0.countryCode + $0.phone) }.sorted() for number in numbers { context.addBlockingEntry(withNextSequentialPhoneNumber: number) print("# Added blocking entry: \(number)") } } When I run this, I see in the console: # Added blocking entry: (*my number with country code*) So it seems the number is added correctly. However, in practice, the number is not blocked on the device. I’ve made sure that: The number is stored with the country code prefix. The extension is enabled in Settings → Phone → Call Blocking & Identification. The extension is reloaded after adding numbers. The array of numbers is sorted in ascending order before calling addBlockingEntry. Despite all this, the number still isn’t blocked. Does anyone know why the print shows the number added, but it doesn’t actually block the call? Am I missing something in the way CXCallDirectoryExtensionContext works? Thanks for any advice!

I've recently run into an issue in Xcode where the sks editor's preview canvas just vanishes for every project on my computer. I don't think it is an issue with my sks files because this works as expected on another computer with the same files, and when it happens it happens for ALL sks files in all projects. There used to be menu items to toggle the canvas and its settings, but those are now gone for me in sks files (they show up for swift files that have previews, however). Any idea what is going on here? How do I get the canvas back? I literally cannot get any work done on my primary computer because of this...

Sorry if this is a dumb question. I’m still a beginner. I created an Xcode Playground app with Microphone and Speech Recognition capabilities enabled, along with a backup Info.plist. However, when running the app on Mac Catalyst, a real device, or the iOS and iPadOS simulators, it crashes right after the Speech Recognition permission popup and again after the Microphone permission popup. For extra context, the app initially worked fine in the Swift Playgrounds app, but that environment uses an outdated SDK, so it no longer supports some of the features I’ve implemented. I’m also struggling to find clear, beginner-friendly documentation that explains how AVAudioEngine works, which is making it hard to understand what’s going wrong and how to debug it.

Hello everyone, I’m stuck with an App Store Connect issue and would really appreciate any insight from the community. I am unable to submit my app for review due to the following persistent error: “Unable to Add for Review – There are still preview uploads in progress.” What makes this particularly confusing is that there are no previews currently uploading. Here is everything I have already tried: Deleted all App Preview videos and all screenshots Confirmed Media Manager shows no active uploads Re-uploaded App Preview videos fully compliant with Apple specs: H.264 AAC stereo audio Constant 30 FPS Correct resolution Uploaded a new build with a higher build number (Build 3) Waited more than 24 hours after upload Logged out / logged in, refreshed, tried multiple browsers and sessions Confirmed TestFlight build upload completed successfully Despite all of this, the error persists and also prevents: Adding the app for review Creating a new app version (the “Add Version” button does not appear) Apple Developer Support has suggested submitting a higher build number, which I have done, but the issue remains. At this point, it seems like a stuck / ghost App Preview upload job on the App Store Connect backend. Has anyone experienced a similar issue? If so: How was it resolved? Did Apple need to manually clear or reset something on their side? Any advice would be greatly appreciated. Thank you in advance.

In the XCode 16 beta, it isn't possible to create a new StoreKit configuration file because the templates list doesn't contain that option. Adding the storekit extension to a file crashes XCode or doesn't have an effect at all. But, loading an existing file still works.

I'm working on a FileProvider which allows access to encrypted files in Dropbox; I can successfully read and present the decrypted files, so I know it's basically working. But I'm having problems getting FileProvider to re-enumerate a folder when its encryption status changes. When the FileProvider receives an update notification saying a folder is now encrypted, I use signalEnumerator to re-enumerate the folder: FileProviderExtension.manager?.signalEnumerator(for: existingItem.itemIdentifier, completionHandler: { (ourError : Error?) -> Void in       if let ourError = ourError {           log("notifyCallback: mount / unmount failed re-enumeration: \(ourError)")       } else {           log("notifyCallback: mount / unmount signalled re-enumeration; pending")       } }) The log reports that the re-enumeration is pending... but as far as I can tell, neither enumerateItems nor enumerateChanges is called on the folder's item unless a Finder window is actually open for that folder. This means that, when an app other than Finder tries to access the files through the filesystem, it doesn't see the updated set of filenames. (For further reference: I've added code to both enumerateItems and enumerateChanges, so that if the call has been triggered by a recent folder-encryption notification, it retrieves a complete set of items from the Dropbox folder. If a retrieved file has an encrypted filename, it reports it as a modified item and returns its filename in-clear; if the filename isn't encrypted, it doesn't return the item (for enumerateItems) or returns it as a deleted item (for enumerateChanges). This approach seems to work successfully for listing folders with a constant state; it's only if the user encrypts / decrypts a folder without currently having a Finder window open inside that folder that I'm not seeing a refresh.) Any advice on how I can force a re-enumeration without a Finder window currently being displayed?

I tried to apply a promotional offer to a subscribed user. When I tested it in the Sandbox environment, it did not show the promotional payment popup but returned a “restored” status. However, when I tested it in the Xcode environment, it correctly displayed the payment popup, but after I tapped the Subscribe button, it showed an “Unable to Purchase” popup like this: And in the console I could see this error: Received error that does not have a corresponding StoreKit Error: Error Domain=AMSErrorDomain Code=305 "Server Error The server encountered an error" UserInfo={AMSURL=http://localhost:56862/WebObjects/MZBuy.woa/wa/inAppBuy, AMSDescription=Server Error, NSDebugDescription=Server Error The server encountered an error, AMSServerErrorCode=3903, AMSStatusCode=200, AMSServerPayload={ "cancel-purchase-batch" = 1; dialog = { defaultButton = ok; explanation = "Contact the developer for more information.\n\n[Environment: Xcode]"; initialCheckboxValue = 1; "m-allowed" = 0; message = "Unable to Purchase"; okButtonString = OK; }; dsid = 17322632127; failureType = 3903; jingleAction = inAppBuy; jingleDocType = inAppSuccess; pings = ( ); }, AMSFailureReason=The server encountered an error} Could someone help me resolve this issue? I’ve been struggling with it for two days and feeling exhausted...

I’m seeing what looks like a change or possible bug in Xcode when creating a new Swift Playground. When I create a Swift Playground using Xcode (File → New → Playground), the project is generated without an Assets folder. I’ve reproduced this multiple times with fresh Playgrounds to rule out user error and the folder is consistently missing. Previously, new Playgrounds included an Assets catalog by default, which makes this behavior surprising.

Hi, I have a recurrent problem with an Xcode workspace that I cannot figure out how to solve: When I command-click a symbol (or press ctrl-cmd-J) to find its definition, and when that definition is in a header file belonging to a custom static library, Xcode opens a header located in the derivedData folder rather than in the project's source codes. The exact location of this file is not in the main 'Build' folder but rather in a folder that seems dedicated to indexing: derivedData/myProject/Index.noIndex/Build/Products/Debug/Include/theHeader.h Consequently the file opened by Xcode is uneditable, I have to close it and reopen the source using another method. Even when the correct header is already opened, and I try again, Xcode reopens the wrong file so that it's opened twice with different paths. In the config file of the main application project, I reference the sources of these static libraries like this: HEADER_SEARCH_PATHS = ${SRCROOT}/myLibrary1/Sources ${SRCROOT}/myLibrary2/Sources ${SRCROOT}/myLibrary3/Sources However, removing this doesn't fix the issue and I don't see any other related-settings. Any idea to fix this annoying issue would be greatly appreciated, thanks!

Hi, I'm interested in trying out Xcode Assist to help with things like complicated refactors or writing tests cases. The ChatGPT and Claude options both share your code with third parties, which is not acceptable for my use case. Has anyone used a fully local model for Xcode Assist? I see that you can select one in the Apple Intelligence section of Xcode's Preferences screen, but don't really know where to start. Are there local models that work well with Xcode Assist and that truly keep your source code private?

Hello, I’ve been experiencing a persistent issue in Xcode since version 26.0, and it is still present in 26.2. When using the split view to display two files side by side, the area in the top‑right corner of the window (the inspector / options panel) starts flickering continuously. This happens regardless of whether I’m using the light or dark theme, and even with the Liquid Glass effect disabled in macOS settings. None of these changes have any impact on the issue. I have already submitted a bug report through Xcode (Feedback Assistant), but the issue is still present as of today. The flickering makes the interface difficult to use and visually very distracting. I’ve attached a video to clearly show the issue. I will review the attachment at the time I publish this post. Thanks in advance for any help or feedback.

My app start up has became horrid. It takes 1 minute to open SQLlite database for my rust core. Impossible to work... I have Address Sanitizer, Thread Perf Checker and Thread Sanitizer disabled...

I'm making a wrapper library to abstract away some of the 'missing platform support' of DeclaredAgeRange until hopefully it expands to additional platforms. When I'm trying to fully enumerate all of the cases of AgeRangeDeclaration, which they all state available starting 26.0 (mysteriously added in Xcode 26.2 beta), the app crashes due to a missing symbol at launch time. This happens both for Xcode 26.1, 26.2 beta 2, and matching Xcode Cloud builds. So I've isolated it beyond "doesn't work on my machine". I just made a handful of crashes and attached a sysdiagnose to a fresh feedback. FB21121092 - DeclaredAgeRange: Eligibility property and new declaration cases unavailable on iOS 26.1 device contradicting documentation - causes runtime symbol not found crash If anyone is curious what these crashes look like I've attached the DiagnosticPayload.jsonRepresentation() generated from one of my favorite frameworks, MetricKit. Very clearly articulated in the diagnostic metadata you can see the symbol not found.

As a side note, thank you for this property, it will let me check what states I need to perform extra checks for in a clean way, I just will need it to now not crash my app on 26.0 and 26.1 runtime devices. :) Edit: DTS did confirm on a comment I had in another thread that this is a bug. Now just to wait for an Xcode beta update. https://developer.apple.com/forums/thread/807906?answerId=867205022#867205022 In any case, this is a great example of how MetricKit totally rocks capturing things other off the shelf crash tools might not have a chance to get. I did have to roll back my TestFlight to an earlier build, but MetricKit was there to send me the previous crashes as soon as the app could launch. Thanks MetricKit team!

Xcode 26.2 RC has been out for over 24 hours and it's still not possible to submit apps.

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.

Hi, I’m seeing an unexpected change in how XCTFail behaves in UI tests after updating Xcode. I use the following helper method: `func waitForExistance(file: StaticString, line: UInt) -> Self { if !(element.exists || element.waitForExistence(timeout: Configuration.current.predicateTimeout)) { XCTFail("couldn't find element: \(element) after \(Configuration.current.predicateTimeout) seconds", file: file, line: line) return self } else { return self } }` In Xcode 16.4, this worked as expected: – when an element wasn’t found, XCTFail was triggered, but the test continued running, allowing my retry logic to execute. After updating to Xcode 26.1 / 26.2 - the test now immediately aborts after XCTFail, without executing the next retry. The logs show: `t = 113.22s Tear Down t = 113.22s Terminate com.viessmann.care:81789 *** Assertion failure in -[UITests.Tests _caughtUnhandledDeveloperExceptionPermittingControlFlowInterruptions:caughtInterruptionException:whileExecutingBlock:], XCTestCase+IssueHandling.m:273 Test Case '-[UITests.Tests test_case]' failed (114.323 seconds). Flushing outgoing messages to the IDE with timeout 600.00s Received confirmation that IDE processed remaining outgoing messages` It looks like XCTFail in Xcode 26 is now treated as an unhandled developer exception, which stops the test execution immediately, even when it’s called inside a helper method. This was not the case in earlier versions. My questions: Is this a regression in XCTest? Or an intentional change in how XCTFail behaves in newer Xcode versions? Should failures now be reported differently (e.g., using record(.init(type: .assertionFailure, …))) if I want to continue the test instead of aborting it? I would like to restore the previous behavior where the failure is logged without terminating the entire test, so my retry mechanism can still run. Has anyone else run into this after upgrading? Thanks in advance! If you’d like, I can also add recommended workarounds that actually work with Xcode 16.4 (e.g., replacing XCTFail with a non-terminating issue record).

It seems Xcode's predictive code completion model is censored. Specifically, when typing the word "torrent," the model stops working completely. It doesn't matter whether the word is written directly in the code or in a comment. It could also be part of another word, such as "qBittorrent." In either case, the model stops working. Reproducing this issue is fairly simple. Create a Swift file and type the word "torrent." The model will stop generating code. Xcode Version 26.2 (17C52) Predictive Code Completion Model: [com.apple.fm.code.generate_small_v2.base: 700.0.81600.13.202379,0] [com.apple.fm.code.generate_safety_guardrail.base: 1.6.81619.13.202072,0] [com.apple.gm.safety_deny.input.code_intelligence.base: 32025010.20251009.91600.100.1651,0] [com.apple.gm.safety_deny.output.code_intelligence.base: 32025010.20251009.91600.100.1651,0] (Installed)

I am developing a simple watch app and I use my personal watch for development with Xcode. Personal watch is series 10 gps only. I have two other watches that I want to use for testing the app, but not needing them to be connected to Xcode. The test watches have cellular option, and I need a cell plan per watch because the watches need to be standalone, not counting initial setup. To get the standalone cell plan the watches need to be configured using AWFK. Here is what I have tried/current issues. I switch between all three watches on my phone using the watch app. Originally tried to put test watches in developer mode, thinking I would connect to Xcode, developer mode is not available when watch is setup using AWFK. Pushed the watch app to apple connect, setup TestFlight group, added the test users and my phone user, accepted invites TestFlight is installed on my phone, I see the testflight setup for the watch app I set a test watch using watch app on the phone, run install for the test app from TestFlight on the phone, spinner moves for awhile then goes back to Install. I am not able to get the watch app installed on the test watches from the phone. Is what I am attempting to do supported? I haven't found much specific documentation on this. If I pair the test watches as regular watches, set them to developer mode, can I pair them again as AWFK and will developer mode survive the switch? Or is there something really simple that I'm overlooking? Appreciate any help that can be extended.
