I recently updated to macOS sequoia 15.6 Afterward, I updated to Xcode 26 The project I've been running for the last couple years no longer compiles on existing simulators and doesn't build to a physical device. I'm getting an error I'm not familiar with and have no idea how to directly resolve it: The specific error is 'Command SwiftGeneratePch failed with a nonzero exit code' Looking up this issue via Google, there wasn't really a lot of information on this particular build failure. Most suggestions were to change the location of the Derived Data folder (Xcode -> File -> Project Settings -> update location of derived data from default to relative) This was one of the only actionable solutions I found online but this doesn't fully address the issue for me, it just creates a new issue: "Command PhaseScriptExecution failed with a nonzero exit code" I feel like with enough digging around I should be able to find a solution to the "PhaseScriptExecution" issue; there seems to be a decent amount of information online about that particular problem. I would prefer if I could solve the original 'SwiftGeneratePch" failure without needing to address other issues, though. Is this possible?

I am experiencing a critical issue with the Apple Developer Portal where certificates are being created under the incorrect Team ID despite being logged into the correct team context. I am logged into the Apple Developer Portal under "Company LLC (Team ID: 12345678)" However, when creating "Apple Development" certificates through the portal, they are being assigned Team ID "987654321" (my personal developer account) This occurs even when explicitly creating certificates from within the Company LLC team context. The same is happening if I tried to create the IOS Development Certificate in Xcode, same issue, creates the certificate with the wrong Team ID This is preventing me from Archive my app in Xcode so i can upload the new version of my App in the App Store. Please Help. Thank you in advance

I have an early-stage framework project where the Xcode project directory is named HXiMateSDK. When I switched to a new Mac device, the framework compiled using the newly installed version of Xcode failed to compile in the old version of Xcode on the old machine. My clients might use my framework in different Xcode versions, so I need to resolve this issue. STEPS TO REPRODUCE The built product HXiMateSDK.framework from the new machine A, which was compiled using the latest Xcode version 26.0.1 (17A400). When creating a new project justTestNew on the new machine A using the latest Xcode version 26.0.1 (17A400), calling the method getSDKVersion from the HXiMateSDK.framework compiles successfully. When creating a new project justTestOldEnv on the old machine B using Xcode 13.2.1 (13C100), calling the method getSDKVersion from the HXiMateSDK.framework results in a compilation failure.

Hi all, Has anyone else run into this issue in Xcode 26? I’m logged into my paid ChatGPT Plus account, but the Xcode integration doesn’t seem to recognize the subscription. After a short period of use, I get the following error: “Over daily limit. ChatGPT in Xcode will be unavailable for up to 24 hours. For higher limits, sign in with a paid ChatGPT account.” Since I’m already signed in with a paid account, this looks like either a bug or a limitation specific to Xcode. Is this expected behavior, or has anyone found a workaround to make Xcode properly recognize Plus accounts? Thanks in advance for any guidance.

Looking for a way to overcome this issue when starting UI tests that used to be working: Source was stale 337 times within the last 500 ms (12 (latestGeneration) != 22 (lastKnownShmemState)): CFPrefsPlistSource<0x600003004c60> (Domain: com.apple.Accessibility, User: kCFPreferencesCurrentUser, ByHost: No, Container: ###/data, Contents Need Refresh: Yes) ... Failed to initialize for UI testing: Error Domain=XCTDaemonErrorDomain Code=18 "Timed out waiting for AX loaded notification" UserInfo={NSLocalizedDescription=Timed out waiting for AX loaded notification} Message from debugger: killed The environment is Xcode 16.3 with iOS Simulator 18.0. Not using the latest Simulator 18.4 because of another bug with network requests: https://developer.apple.com/forums/thread/777999

To reproduce this bug create a new Xcode Project for IOS choose UIKit. In the app delegate add the following lines. As you can see in the above image . Line 19 with the initialization of PHPickerViewController has no compilation failure. Now lets add import WidgetKit As soon as widgetKit is imported a compiler error is thrown which is PHPickerViewController is not in scope. This worked with Xcode 16.4 It was possible to have a swift file with both WidgetKit implementations and PhotosUI implementations. This behavior has changed in Xcode 26/26.0.1 . Does anybody know why this happens , could not find any clues within the different versions of documentations. P.S Found a work around which raises further questions Adding import SwiftUI fixes this problem , I am genuinely curious on how this is happening on a compiler level.

It looks like the other thread got locked. I would still like to be able to uncheck the box for "Connect via network" so I can develop with my iOS 17+ devices normally with Xcode 15. Or a method to use Xcode 14 with iOS 17+ without CoreDevice or whatever the problematic API is.

I have a mac mini on OS 15.7 ( Sequoia ) with 4-5 iPhone and iPad devices on version iOS 26.0 Stable connected to it. I am trying to build a device farm application where it run multiple UI tests to restore the device state but facing BUILD INTERRUPT intermittently during the UI test run. What can be the issue here? Is it device side issue OR issue with device and xcode connection. What tools can I use to gather more information of xcode and its processes or memory leaks due to it. Could any network call interruption via xcode can lead to this issue.

I have added an in-app purchase function into my app, and have enabled in-app purchase profile in developer portal(it's on by default and is marked gray in developer portal, I don't know if that's how it supposed to look like). I have issued the agreements and tried signing the app both manually and automatically, but neither of that worked. App can be built successfully in simulator but does not show the simulation window, but cannot build on real device or archive. Errors: Missing com.apple.developer.in-app-purchase, com.apple.developer.in-app-purchase.non-consumable, and com.apple.developer.in-app-purchase.subscription entitlements. Automatic signing failed Xcode failed to provision this target.

Hello, I am currently working on personal project based on Matter. I need to create a Basic Video Player as specified in Matter's standard embedding the Media Playback Cluster. I went through the reading of how Apple now supports Matter as a standard : linkText My understanding of the following schematic, is alongside : HomeKit Accessory Protocol (HAP) Framework API Related HAP accessories underneath the homeKit framework. Developpers also find under the Homekit framework : CHIP (Connected Home IP) Framework API Related Matter accessories this time Both types of accessories/devices can be commissioned in the HomeKit ecosystem seemlessly. Each framework has it's documentation : HAP : https://developer.apple.com/documentation/homekit/hmhomemanager CHIP : https://developer.apple.com/documentation/matter I want through the process of installing XCode and the HomeKit Accessory Simulator. In the list of HomeKit Accessories I did not see any Media related devices : The list of currently supported devices is limited as I read here and will be enriched with time : https://support.apple.com/en-us/102135#:~:text=The%20Home%20app%20currently%20supports,%2C%20temperature%2C%20and%20humidity). In the meantime, as I read the matter documentation, I read several references made to the Media Playback : https://developer.apple.com/documentation/matter/mtrclustermediaplayback https://developer.apple.com/documentation/matter/mtrbaseclustermediaplayback https://developer.apple.com/documentation/matter/clusters#Interacting-with-the-Media-Playback-cluster My questions are : Are Matter Basic Video Players, (Media Playback) supported in HomeKit ? Why aren't they listed in HomeKit Accessory Simulator ? How can I add a Basic Video Player in HomeKit and display it's Media Playback controls once I have added the device to HomeKit ? Thank you for your Answer. Regards David

I am currently developing a macOS app that can show system HUDs in the Notch Till Sequoia I used to kill the OSDUIHelper process (which displays the default macOS Volume and Brightness control HUDs) - and replaced it with my app's HUDs But, it is not working on macOS Tahoe anymore as the OSDUIHelper process is no longer there due to the UI changes Has the process been renamed - or is there any other way to kill the process?

Converted my app to use a Storyboard instead of a Launch Image. Everything was working fine until I removed all of the Launch Images within Image.xcassets. I kept the icons. Then I started getting an error that: "None of the input catalogs contained a matching image set named "LaunchImage". The storyboard imageview referenced an image not inside of LaunchImage catalog (but perhaps it did now that its causing this problem). I rebuilt, clean build, checked plist for entry and got the same error. I figured there was something wrong with the Storyboard so I completely removed it, rebuilt a new one, new name new image file, assigned the png file to the imageview and I get the same error. I've tried everything. There must be some deep metadata assignment that is looking for this catalog, so I put it back in, with the files assigned to universal 1x, 2x and 3x. I used LaunchImage as the image file and it recognized it but still get the same error during build. I can even remove the storyboard and I get the same error. We are not using Swift, but Objective C xcode.

Hi so i have a given project where I am trying to use components within the PhotosUI Framework with Xcode26 and Xcode26.0.1 Just for reference here is an attached screenshot This sample code compiled successfully with xcode16.4 and was in production. There is no change in the pbxproj file , all the build settings have remained the same. Attaching it for reference. project.pbxproj.txt While showing declarations of PHPickerViewControllerDelegate i get two options which is the same as in Xcode16.4 while browsing online found this reddit thread which is very similar https://www.reddit.com/r/Xcode/comments/1nkku20/my_project_wont_compile_after_xcode_26_update_due/ Pls help :)

Hello I have a problem with provisionprofile file. I have created Identifier with Sign in with Apple capability turned on, created Profile with Developer ID selected and now I try to export archive with generated Developer ID provision file but it says "Profile doesn't support Sign in with Apple" Also interesting thing that default provisions like macOS App Development Mac App Store Connect don't show such error when I try to export archive Maybe this problem is only related to Developer ID provision and Direct Distribution doesn't support Sign in with Apple, but I havent found proves about this idea

I have an iOS app with a QuickLook extension. I also added Apple Vision Pro in the target's General > Supported Destinations section. About one year ago, I was able to run the app on iPhone, iPad and Apple Vision Pro Simulators. Today I tried running it again on Apple Vision Pro with Xcode 26.0.1, but Xcode shows this error: Try again later. Appex bundle at ~/Library/Developer/CoreSimulator/Devices/F6B3CCA8-82FA-485F-A306-CF85FF589096/data/Library/Caches/com.apple.mobile.installd.staging/temp.PWLT59/extracted/problem.app/PlugIns/problemQuickLook.appex with id org.example.problem.problemQuickLook specifies a value (com.apple.quicklook.preview) for the NSExtensionPointIdentifier key in the NSExtension dictionary in its Info.plist that does not correspond to a known extension point. I tried again later a couple times, even after running Clean Build Folder Immediately, without any change. I can reproduce this with a fresh Xcode project to which I add a Quick Look Preview Extension and Apple Vision Pro as a supported destination. The error doesn't happen when running on Apple Vision Pro (Designed for iPad) or iPad Pro 13-inch (M4) destinations. What is the problem? I created FB20448815.
