I am using MacOS 26.1 and Xcode 26.1; my existing project cannot select a simulator, but creating a new project allows me to select a simulator normally.

I have download the 26.1 simulator after updating app this morning then out of the blue Xcode prevents me from running app and forces me to download sim again.

With Xcode 14, the device selection on the bottom of the storyboard canvas has changed, and the iPhone 12 and 13 mini screens are no longer there, as well as there only being one model of iPad. Is there a way to add more devices to this section? I have simulators installed for these devices, and this is the way I've been checking compatibility so far, but this is not sustainable. I appreciate any help that you can give me.

Hey everyone, I’m trying to notarize a macOS app for direct distribution through Xcode, and the notarization step has been stuck on “In Progress” for hours now. The upload completed fine, but since then I haven’t gotten any feedback at all: no email, no notification. Organizer just shows: Status: In Progress I’ve tried closing/reopening Organizer, and even re-archiving the app, but it always sits in the same state. Is this just a delay on Apple’s side, or is there something I might have misconfigured? Any tips on how to get more insight into what’s going on? Thanks!

I am unable to download the iOS 26.1 Simulator Runtime through Xcode 26.1 on macOS 26.1 (Build 25B78). Issue Details: When attempting to download via Xcode Settings → Platforms, the download fails with error code 41 (DVTDownloadableErrorDomain) and error code 60 (MADownloadCannotConnectToHost) The error message states: "Failed fetching catalog for assetType (com.apple.MobileAsset.iOSSimulatorRuntime), serverParameters ({RequestedBuild = 23B80;})" I receive HTTP 403 Forbidden when accessing mesu.apple.com/assets/ Steps Attempted: Downloaded via Xcode Settings → Component → iOS 26.1 Simulator Tried command line: xcodebuild -downloadPlatform iOS Searched https://developer.apple.com/download/all/ - iOS 26.1 Simulator Runtime not listed Tested with different networks (home WiFi, VPN, mobile hotspot) Disabled proxy settings Flushed DNS cache All attempts result in the same error. Important Notes: Xcode 26.1 shows iOS Simulator SDK 26.1 (Build 23B77) is available However, Xcode attempts to download Build 23B80, which appears unavailable I experienced a similar issue previously with Xcode 16.4 requesting iOS 18.4 Simulator Runtime, which was also unavailable for download Impact: Without the iOS 26.1 Simulator Runtime, I cannot develop or test iOS applications. macOS 26.1 requires Xcode 26.1, which in turn requires iOS 26.1 runtime, leaving me unable to perform any iOS development work. Questions: Is iOS 26.1 Simulator Runtime (Build 23B80) officially released? Is there a direct download link available? Should Xcode 26.1 be requesting Build 23B77 instead of 23B80? Is there any account restriction preventing me from downloading newer simulator runtimes? System Information: macOS: 26.1 (Build 25B78) Xcode: 26.1 (Build 17B55) Error description: Download failed.

I have placed a .contextignore file next to my .xcworkspace file, it's contents look like this: CHANGELOG.md *.generated.swift *.mockingbird.swift However I'm still getting files that match these globs in my project context requests when using Coding Intelligence with a 3rd party provider (Gemini) What am I doing wrong?

I'm seeing a lot of unexpected CPU usage when running the iOS 26.1 simulator. Looks like a "MercuryPosterExtension" is crashing over and over, which then causes the "ReportCrash" process to run, presumably to create the crash report. Doesn't happen on device, nor on iOS 26.0 simulator. I suspect MercuryPoster is related to wallpaper. I also don't see any wallpaper background in my simulator.

We got an app for iPad which has two targets one for the App itself (MainApp target ) and another one for the Driver ( Driver Target ) using DriverKit. The app works fine in Development, but I'm trying to distribute it with adhoc. I've requested the Distribution Entitlement to Apple, after getting it, the App Id for the Driver has the following Capabilities: DriverKit, DriverKit (development), DriverKit USB Transport (development), DriverKit USB Transport - VendorID, In-App Purchase Now in the profile section, I've created a adhoc profile for the Driver AppId (Identifier). Obviously I've also created an Adhoc profile for the Main AppId Finally in the Signing & Capabilities Section I set up the profiles for MainApp target, int the Debug one I set up the Development one and int the Release one I set up the adhoc one. I do the same in the Driver Target, but when I set up the Adhoc one in the Release, I've got a warning: Xcode 14 and later requires a DriverKit development profile enabled for iOS and macOS. Visit the developer website to create or download a DriverKit profile Also interestingly the Signing Certificate section says: None I also set up the Capabilities for the Driver Target: DriverKit USB Transport - VendorID DriverKit USB Transport ( Development ) Inside these capabilities I set up the vendor ID as dictionary The problem is, if I try to Archive the app I will get the previous Warning message as error: Xcode 14 and later requires a DriverKit development profile enabled for iOS and macOS. Visit the developer website to create or download a DriverKit profile. Any idea what I'm missing? Thanks

Lots of pepole is wait for Xcode to be in for 15 years. And peole and kids especially me are crying about it swift is the worst its good but you can’t change the screens iPhone Xcode is better so how do I get Xcode for iPadOS?

In the Swift UI tutorial on the official website of apple developers, https://developer.apple.com/tutorials/swiftui/creating-and-combining-views, Step 2 in Section 2, through Command-Control-click, the full menu in Figure 1 cannot appear, but the style of Figure 2 appears, and the "Show SwiftUI Inspector" option is missing, see Figure 2. Similarly, in Step 6 of Section 2, "Control-clicking on the Text declaration in the code editor", the options in the red box in Figure 3 cannot appear, and It is the style of Figure 4, and all the options in the red box of Figure 3 are missing. There is no one in Show Coding Tooks. I am using Macbook air 2020 M1, macOS is the latest Tahoe 26.1, and the xcode version is 26.1. The project files used in the learning tutorial are downloaded directly from the above link. Thank you very much for your help to a beginner, which is very urgent for me. I look forward to your reply and sincerely thank you again.

My iPhone no longer works for on-device debugging. This same phone, same Mac, and same cable worked before. Now Xcode always shows the device as Unavailable. System: • macOS 15.6.1 • Xcode 26.1.1 (17B100) • iPhone on iOS 26.0.1 with Developer Mode enabled • Direct USB-C connection, trust prompt appears normally Symptoms: The device appears in Xcode and in devicectl, but always in the “unavailable” state. JSON output shows pairingState: unsupported and ddiServicesAvailable: false, meaning USB sees the phone but debugging services won’t start. Already tried: • Reinstalled Xcode • Reset trust on both Mac and iPhone • Toggled Developer Mode • Reset Location & Privacy • Cleared pairing records in /var/db/lockdown • Restarted usbmuxd • Deleted ~/Library/Developer and /Library/Developer • New cable, direct port, phone unlocked • Full Mac reboot None of these changed anything — the device stays unavailable. Question: Has anyone seen iOS 26.x devices stuck as “Unavailable” in Xcode 26.1.x? Is there a known CoreDevice/devicectl issue on macOS 15.6.1? Any fix that does not involve wiping the phone? Thanks!

I just updated to Xcode 26 and some of my Swift Packages have been getting strange build errors that I have not been able to resolve. When I try to build my Swift Package in Xcode I get the following error Module dependency cycle: 'UIKit.swiftmodule -> .swiftmodule -> SafariServices.swiftmodule -> UIKit.swiftmodule' It seems like it is related to the change in Xcode 26 that states "Swift explicit modules will be the default mode for building all Swift targets". I see that you can disable this with the build setting SWIFT_ENABLE_EXPLICIT_MODULES=NO, but I don't see a way to do this in Package.swift, as you can't include value assignments like this .define("SWIFT_ENABLE_EXPLICIT_MODULES=NO"). Our private SPM repos use CI/CD and so we need to be able to build them independently of any use in a project. I would appreciate any help on fixing our Swift Package builds in Xcode 26, thanks!

After upgrading to Xcode 16.4, the navigation arrow icon in the Report Navigator is no longer appearing for failed test cases within XCResult bundles. This icon, which allows developers to directly navigate to the specific line of code that caused a test failure, is now missing. This significantly hinders the debugging process for test automation engineers. Details: Xcode Version: 16.4 (issue started after upgrade) Test Framework: XCTest Test Environment: iOS simulators Execution Method: The tests are executed on a Jenkins CI/CD server XCResult Analysis: The generated .xcresult bundle is downloaded from the Jenkins server and opened locally on a Mac also running Xcode 16.4. Observed Behavior: The navigation arrow icon is missing, and there is no direct way to jump to the failure line from the report. This issue appears to be a regression introduced in Xcode 16.4, as the navigation arrow was consistently present in previous versions. Any insights or workarounds would be greatly appreciated.

We are getting following error in xcode cloud "The step invocation hit a user timeout. The xcodebuild archive invocation timed out. No activity has been detected on stdout, stderr or the result bundle in 30 minutes" We are using following env to create a build. Xcode: 14.2 Macos: Ventura 13.2.1 We didn't face any issue in Ventura 13.2.0 and we are seeing this issue in our first build using ventura 13.2.1. The difference I see between successful and failure build, I don't see "Discovering Swift tasks after 'Compiling { list of swift file " in a failed build. I see compiling { list of swift file } and end of the compilation, the build is failing.

Hello Team, I try to delete photo from Photos for that i used this method, [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{ [PHAssetChangeRequest deleteAssets:@[assetToDelete]]; completionHandler:^(BOOL success, NSError *error) { }]; This method pops up a dialog with Don't Allow or Delete. But some time in some iPhones not respond PHAssetChangeRequest deleteAssets method that's why that completionHandler not called because of that i can't perform any operation of PHPhotoLibrary then after. If I restart my iPhone then it works. Many users of my app complained about this issue. I have an iPhone 11 with iOS 15.3. But some iOS 12,14,16 users also face the same issue. So what exact issue is there? Is it related to iOS or a method? Thanks, Ankur

I'm attempting to install a previously downloaded .xcappdata to my running application on the iPadOS Simulator (running iPadOS 26.1), but the app data won't transfer to the simulator. I've created the Xcode basic iPadOS app template, without any code modifications - adding some items to the list and downloading the .xcappdata from an attached iPad (running iPadOS 26.1). I can remove the app from the iPad and re-attach the .xcappdata to the physical iPad - no issues there. The issues I'm having is when trying to attach the app data on a simulator. Steps I've tried: Manually drag and dropping the .xcappdata file to the simulator. I get a popup saying "Simulator device failed to install application data container." Attaching the .xcappdata through Xcode in the "Edit Schemes"->Options->App Data App starts fresh without any errors or items from the .xcappdata file Installing the .xcappdata file through the command line through xcrun simctl install_app_data <SIM_DEVICE_ID> <MY_XCAPPDATA> This gives an error: Simulator device failed to install application data container. Could not get the existing data container location for the app. Container manager error code: 55 Underlying error (domain=com.apple.containermanager, code=55): Failed to install the requested app data package Could not get the existing data container location for the app. Container manager error code: 55 I can however reach the "data container location" through the xcrun simctl get_app_container command, leading me to think there are some issues with underlying permissions?

Hello everyone, I'm encountering a persistent issue with my newly created widget project, even though it’s a clean, minimal setup. Every time I try to run the widget on the simulator or a device, I get the following error message: [S:1] Error received: Connection invalidated. I get this error even in a new project (I just created a new one) when I add a widget extension to it. The app itself works fine—no errors—but when I try to install the widget extension, it always shows me this error. Initially, I thought the issue was caused by an incorrect URLSession, but even after creating a clean (default) widget extension, the issue persists. I don’t know what to think anymore. Has anyone encountered this before? It’s completely blocking my progress. Conditions - new project from iOS App template WidgetExtension from template with no changes Iphone 14 pro IOS - 18.3.2

ChatGPT in Xcode 26.1 is super slow for me. What used to complete in a batter f seconds is now taking tens of minutes. Context: M2 Pro MBP, Xcode 26.1, macOS 26.1. CPU stays under 50% while ChatGPT returns. Using the minimal setting. Tried restarting, have verified I have nothing running Electron, no other apps are running. ChatGPT returns fast for the displayed content but the preview window where it renders code per line takes a few seconds per line.

Since iOS 26.1 the AlarmKit alerts don't work anymore on simulator when the screen is locked. This is also still broken on the current Xcode 26.2 beta. They do trigger on the home screen and in-app though. Also on device everything works fine. Is there any secret trick to make it work again?
