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.

I am using SwiftData for my model. Until Xcode 15 beta 4 I did not have issues. Since beta 5 I am receiving the following red warning multiple times: 'NSKeyedUnarchiveFromData' should not be used to for un-archiving and will be removed in a future release This seems to be a CoreData warning. However, I am not using CoreData directly. I have no way to change the config of CoreData as used by SwiftData. My model just uses UUID, Int, String, Double, some of them as optionals or Arrays. I only use one attribute (.unique).

Hello together. Since a few weeks I have the problem, that both of my iPhones (iPhone 15 with iOS 26.4.1 and an iPhone Xs with iOS 18.7.4) are NOT recognized by xcode, but are visible in Mac Finder this is what xcode shows: When I click on that I see this: and in finder: I tried everyhting I re-installed XCode 5 times and deleted ALL XCode folders manually I restarted all devices and today I completely reinstalled my mac My Macbook has iOS 26.4.1 as well and XCode is freshly installed from App Store

Several app developers are struggling with the inability to provide a separate app icons that looks nice on older macOS versions while at the same time provide Icon Composer icons that look great on macOS Tahoe 26. An ability to provide separate icons is super important to those who have app icons that follow the curvature of the default icon borders (as the corner rounding radius is different for Sequia and Tahoe). Take a look at this for example: https://github.com/ghostty-org/ghostty/issues/7564#issuecomment-3042061547 Question: Is there a definitive/recommended way to address this issue? How can a developer add a glass icon variant that looks good on Tahoe and provide a bitmap icon for older macOS versions? Some background info: Prior to Xcode 26 beta 4, one could add an App Icon to Assets to be used as app icon for legacy macOS versions (Sequia and older) and use a new Icon Composer icon (placed in the project root) for macOS Tahoe 26. Enabling "Include all app icon assets" under target settings ensured that older macOS versions would use the old app icons while Tahoe the new Icon Composer glass one. Since Xcode beta 4 this technique no longer works. Xcode instead insists on populating Assets.car with Icon Composer generated variants, disregarding the App Icon provided in Assets. Although the App Icon in Assets makes its way to a .incs file in the app bundle's Contents/Resources folder, but that is not used by macOS anymore and is there for some compatibility purposes. The Assets.car file (which matters) only contains the variants generated by Icon Composer and does not contain the png icons provided in the Assets.

After updating to Xcode 26.4 (public release), I’m no longer able to paste from the Mac clipboard into the Simulator. Automatically Sync Pasteboard is on, and I have content on the clipboard, but paste doesn’t work—Cmd+V does nothing, and there’s no Paste option in the context menu. Is anyone else seeing this?

Hello! I am attempting to add Subscriptions to an App that Is already published on the App Store. I cannot get Xcode to actually sync what is in my App Store Connect. When adding the Storekit configuration file, I go through the automatic linking process and select the proper bundleID. The configuration file says 'Synced @ [CurrentTime]' however there are no subscriptions listed in there. I have attempted deleting the file several times, creating a new subscription group. With no success. Do I need to publish the subscriptions without the features first? Upon attempting to write the supporting code that will enable these features within the app, I cannot get Xcode to identify that I have these subscriptions. I have also tried pushing these to TestFlight, still with no success. Thank you.

I have an orphaned asset folder taking up 9.13GB located at: /System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime/c0d3fd05106683ba0b3680d4d1afec65f098d700.asset It contains SimulatorRuntimeAsset version 18.5 (Build 22F77). Active Version: My current Xcode setup is using version 26.2 (Build 23C54). I checked the plist files in the directory and found what seems to be the cause of the issue: The "Never Collected" Flag: The Info.plist inside the orphaned asset folder explicitly sets the garbage collection behavior to "NeverCollected": <key>__AssetDefaultGarbageCollectionBehavior</key> <string>NeverCollected</string> The Catalog Mismatch: The master catalog file (com_apple_MobileAsset_iOSSimulatorRuntime.xml) in the parent directory only lists the new version (26.2). Because the old version (18.5) is missing from this XML, Xcode and mobileassetd seem to have lost track of it entirely. What I Have Tried (All Failed) Xcode Components: The version 18.5 does not appear in Settings -> Components, so I cannot delete it via the GUI. Simctl: xcrun simctl list runtimes does not list this version. Running xcrun simctl runtime delete 22F77 fails with: "No runtime disk images or bundles found matching '22F77'." Manual Deletion: sudo rm -rf [path] fails with "Operation not permitted", presumably because /System/Library/AssetsV2 is SIP-protected. Third-party Tools: Apps like DevCleaner do not detect this runtime (likely because they only scan ~/Library or /Library, not /System/Library). Has anyone found a way to force the system (perhaps via mobileassetd or a specific xcrun flag) to re-evaluate this folder and respect a deletion request? I am trying to avoid booting into Recovery Mode just to delete a cache file. Any insights on how AssetsV2 handles these "orphaned" files would be appreciated.

I purchased my Apple Developer program on April 16, 2026. It’s been 4 days now, and my status is still stuck on "Pending." What’s worse is that the system is now prompting me to make the payment again. I know many of us are experiencing this exact same issue right now. I am from Thailand, so I decided to make a phone call to the Apple Developer support team to get this sorted out. They told me that due to a massive volume of requests, it might take a very long time to approve. They promised to "expedite" my process, but completely failed to provide any specific timeframe or even an estimated date of approval. Honestly, it felt like the support agent was just reading from a script to calm me down without actually offering any real help—they didn't even ask for my Order Number to check my case! Based on how this is being handled, I strongly believe that anyone reading this who is stuck in the same situation might have to endure this problem for months. Has anyone actually gotten their account approved recently?

Getting macOS app icons from Icon Composer working in Xcode 26.x appears to have caused widespread confusion. I've certainly had more than one headache from it. Here's what works for me: Drag the .icon file from Icon Composer into the Xcode Project Navigator, dropping it at the same level as Assets.xcassets — not inside it. In the Project Navigator, click the top-level project item to open the Project Editor. Select your app target and open the App Icons and Launch Screen section. Enter the icon name (without the .icon extension) in the App Icon field. In that same section, leave App Icons Source unchecked. Go to the Build Phases tab and expand Copy Bundle Resources. Delete the Assets.xcassets entry, leaving only the .icon file. Clean the build folder (⇧⌘K) and run. Your icon should now appear in the Dock. It appears that Icon Composer icons and even the presence of the Asset Catalog icons in Copy Bundle Resources are mutually exclusive right now. Including the Asset Catalog appears to suppress the Icon Composer icon. Removing it lets the Icon Composer icon through. Note: If your app depends on other assets in the Asset Catalog, this approach won't work for you. In that case, fall back to the traditional method — export all required sizes from Icon Composer and import them into the Asset Catalog. Hopefully Apple addresses this conflict soon.

I've recently installed 26.1 Beta 3 alongside stable 26.0.1 When building my app with 26.0.1 the final .ipa size is ~17mb, however after building my app with 26.1 Beta 3 the size has increased up to ~22mb The main difference is Assets.car blowing from 1.1mb to 5.6mb (or 8.6mb if I include all icons settings). Upon examining I've found new liquid glass .icon file duplicating itself multiple times as png variants (any, dark, tinted, etc). Is anyone else experiencing this issue?

I’m seeing a regression in Xcode 26.4 where Interface Builder will not allow connecting IBOutlets or IBActions. Symptoms: The usual gutter circle/dot does not appear next to IBOutlet / IBAction in the code editor Because of this, I cannot: drag from storyboard → code drag from code → storyboard The class is valid and already connected to the storyboard (existing outlets work) Assistant Editor opens the correct view controller file Important: The exact same project, unchanged, works perfectly in Xcode 26.3. I can create and connect outlets/actions normally there. ⸻ Environment Xcode: 26.4 macOS: 26.4 Mac Mini M4 Pro 64G Ram Project: Objective-C UIKit app using Storyboards This is a long-running, ObjC, project (not newly created) ⸻ What I’ve already tried To rule out the usual suspects: Verified View Controller Custom Class is correctly set in Identity Inspector Verified files are in the correct Target Membership Verified outlets are declared correctly in the .h file: @property (weak, nonatomic) IBOutlet UILabel *exampleLabel; Opened correct file manually (not relying on Automatic Assistant) Tried both: storyboard → code drag code → storyboard drag Tried using Connections Inspector Clean Build Folder Deleted entire DerivedData Restarted Xcode Updated macOS to 26.4 Ran: sudo xcodebuild -runFirstLaunch Confirmed required platform components installed Reopened project fresh ⸻ Observations In Xcode 26.4 the outlet “connection circles” are completely missing In Xcode 26.3 they appear immediately for the same code Existing connections still function at runtime — this is purely an Interface Builder issue ⸻ Question The gutter circles appearance has always been flaky in Xcode over the 13+ years I've been using it but now with 26.4 they have completely disappeared. Has anyone else seen this in Xcode 26.4, or found a workaround? At this point it looks like a regression in Interface Builder, but I haven’t found any mention of it yet.

Hi, I'm trying to build an App Store IPA for my Flutter app on Mac M4 without a physical iPhone connected. STEP 1 - I tried Automatic Signing in Xcode but got: "Communication with Apple failed. Your team has no devices from which to generate a provisioning profile." "Xcode couldn't find any iOS App Development provisioning profiles matching my bundle ID." STEP 2 - I switched to Manual Signing in Xcode. No warnings or errors shown in Xcode UI. Everything looks fine in Signing & Capabilities. But when I run this command in terminal: flutter build ipa I get this error: Building App Store IPA... Encountered error while creating the IPA: error: exportArchive "Runner.app" requires a provisioning profile. My Setup: Mac M4 Flutter (flutter build ipa) Paid Apple Developer account No physical iPhone connected Building for App Store distribution Question: How do I successfully export an IPA for App Store distribution without a physical device on Mac M4? Any help appreciated. Thank you.

Whenever I try and talk to chatgpt codex in Xcode, I get the request could not be completed error with this tag: JSON-RPC global stream failed: The operation couldn’t be completed. (IDEIntelligenceAgents.JSONRPCElement.Error error 1.) Chatgpt chat still works inside of xcode, however codex does not work. I have not hit my limit for codex. This issue happened after the xcode update. (I belive 26.4.1)

Got a broken frame when using Xcode to capture a frame and replay it from a Unity game. It seems like the vertex buffer is broken; I see a bunch of "nan"s in the vertex buffer. However, the game displays correct when running, and it only happend when I upgrade my Xcode and iphone to Xcode26 and IOS26 ios26

I cannot get a Jiggle on an iPhone 15 using the iOS 17.0 simulator. I cannot drag icons or widget around, only have the option to remove them. On both the iOS 17.0 and iOS 26.4 (running on an iPhone 17 simulator) There is nothing in my drawer for adding a widget, no system widgets either (attached screenshots). Just the Search Widgets bar that does have widgets in it. The system widgets are in the screen to the left of the home screen. I can put widgets I find through the search on the home screen. Although on the iOS 17 emulator no jiggle means no repositioning. May computer is running MacOS 25.4.1 and the latest versions of everything. I have asked AI, I have tried wipes, locking, unlocking, reseting, re-installing, light mode/ dark mode to refresh any cached images, trying to drag system widgets from the left side of the home screen, "a widget kit development mode option" in settings > developer on the iPhone and something using the command line for chronosd that never worked. The iPhone 17 simulator has been like this for a couple of weeks as that was when I started widget development. The iPhone 15 simulator was only downloaded and installed today. I only know there should be images on the "Widget Gallery" or "Widget Picker" from my son's iPhone Any help or suggestions would be appreciated, Thank you. iPhone 15 simulator running iOS 17.0 iPhone 17 simulator running iOS 26.4.1

The sample code just draw a triangle and sample texture. both sample code can draw a correct triangle and sample texture as expected. there are no error message from terminal.

Here are sample codes. Sample Code Test Environment: M1 Pro MacOS 26.3 (25D125) Xcode Version 26.2 (17C52) Feedback ID: FB22031701

Hello Team, We’ve confirmed Apple’s current minimum OS requirements for Xcode 26: iOS 15 – 26 iPadOS 15 – 26 tvOS 15 – 26 watchOS 8 – 26 visionOS 1 – 26 macOS 11 – 26 Are we correct in understanding that any builds targeting below these versions are no longer accepted by the App Store and may fail to launch for users on older systems? Like this https://developer.apple.com/forums/thread/821370?answerId=882822022#882822022 For Steam macOS distribution, can older macOS targets still be supported, or should we align strictly with Apple’s minimums? Thank you and best regards, Phong

When I use Xcode 26 (0.1, 1) for debugging and hit a breakpoint, using "step over" causes the debugger to freeze at a random line of code. Clicking "Pause program execution" indicates that the line is being executed, but the breakpoint never exits, seemingly causing a freeze. The application on the simulator also becomes unresponsive. However, when I do not use breakpoints, my program runs smoothly, and debugging on a physical device does not cause any freezes. This issue only occurs with the simulator. I am using Xcode on Apple Silicon, and due to some third-party SDKs that depend on Rosetta, our app can only run on the Rosetta simulator. We did not encounter this issue when using Xcode 16.x for simulator debugging. The current situation with Xcode 26.x significantly reduces our development efficiency. What could be causing this, and is there a solution?

Hello, I’m developing an Apple Watch companion app for my swimming application and the app keeps uninstalling/disappearing from Apple Watch. I have a specific Scheme to install it to my watches, it appears there, I can debug but after a while it disappears. It’s my first app for this device but it doesn’t seem normal to me. any idea?

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.

When a static library is built with Xcode 26 (with deployment target set to iOS 13) and then linked into an app project compiled with Xcode 16, the build process fails with the following linker error: Undefined symbols for architecture arm64: "_swift_coroFrameAlloc" This occurs even though both the static library and the app project have their deployment targets set to iOS 13.0. The static library works on Xcode 26, but fails to link on Xcode 16. This issue shows up with certain Swift syntax. For example, in my case, using a property getter and setter caused the compiler to emit a reference to _swift_coroFrameAlloc, which in turn triggered the issue. This issue prevents us from distributing pre-built static libraries compiled with Xcode 26 to teammates who are still using Xcode 16. I’ve filed feedback for this issue (FB21130604). Is there any way to work around it? For example, by adding specific Build Settings or something similar? A demo project is available here: https://github.com/Naituw/SwiftLibraryDeploymentTargetIssue The demo project includes: StaticLibraryProject: A simple Swift static library with property getter setter usage AppProject: An iOS app that links against the static library verify_compatibility.sh: An automated script to reproduce the issue Method 1: Manual Build and Verification Open StaticLibraryProject/StaticLibraryProject.xcodeproj in Xcode 26 Build the StaticLibraryProject for iOS device (Release configuration) Locate the built libStaticLibraryProject.a in the build products directory Copy libStaticLibraryProject.a to AppProject/AppProject/ directory Open AppProject/AppProject.xcodeproj in Xcode 16 Build the AppProject for iOS device Method 2: Automated Script Edit verify_compatibility.sh to configure the paths to your Xcode installations: Set XCODE_26_PATH to your Xcode 26 installation path (e.g., /Applications/Xcode.app) Set XCODE_16_PATH to your Xcode 16 installation path (e.g., /Applications/Xcode16.app) Run the script: ./verify_compatibility.sh
