Today's Xcode release won't download the visionOS SDK, gives a 'network error'.

I know there are several existing threads on this topic but things keep changing. The release notes for Xcode 26 beta 3 have the following statements for a couple of resolved issues: Asset Catalog Fixed: Unable to set Icon Composer icon as alternate iOS icon (153305178) (FB18025356) Icon Composer Fixed: Icon Composer icons back deploy to older versions of iOS, macOS, and watchOS with inconsistent rendering. (152258860) I had a working solution under beta 1 and beta 2 for both of these. But under beta 3, I am now seeing the new glass icons for my app when running on a simulated iOS 18 device. This is happening for both the main app icon and any alternates. This contradicts the statement that beta 3 fixes this issue. There is no documentation (that I can find) describing how you are supposed to support old icons for iOS 18 and new glass icons for iOS 26. There is no documentation for how to support alternate glass icons for iOS 26. What I'm doing at the moment (that worked before beta 3) was to have the normal iOS 18 app icons in the Asset catalog and to have the new glass icons added to the project. The filenames for the glass .icon files have the same name as the app icons in the Assets catalog. This worked under beta 1 and beta 2. And despite the Xcode 26 beta 3 release notes stating that Icon Composer icons no longer back deploy to iOS 18, I'm seeing the opposite. Beta 3 now does the opposite of that statement. Does anyone have a working solution that supports old iOS 18 app icons and new iOS 26 glass icons using Xcode 26 beta 3? Note, all of my testing is with simulated iOS devices and I'm running Xcode 26 beta 3 under macOS 15.5. Maybe that's an issue?

I've been messing around with converting my app icons to use Icon Composer. My app has multiple app icons, but I've noticed that I cant seem to set .icon files using the alternate app icon api. I believe this is due to the requirement that alternate app icons live in the Assets Catalogue but .icon files go anywhere in your project. Is there any plan to support this? Or am i missing something? I was able to successfully set a .icon file for the primary app icon.

I’m trying to add my account to Xcode 16.1, which is running on a virtual machine with macOS Sequoia 15.1. I was able to successfully sign in to my account on the virtual machine itself. I’m using a Mac Mini M2, but when I attempt to add my account in Xcode, I encounter the following error: "There was a failure decoding response: (HTTP 401, 60 bytes) The data couldn’t be read because it isn’t in the correct format."

Since first beta of iOS 26 I've created a workflow where I can deploy to TestFlight the builds compiled using the iOS 26 SDK, and it has worked fine until yesterday when I started receiving this error: 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. I haven't changed anything in the workflow so I suspect it's a bug on Apple side? Or am I missing something? It is set to use "Latest Beta or Release" for both Xcode and macOS, archive and deploy to TestFlight Internal Testing. Thank you!

Hi, in our Xcode project we have a Tooling package, which defines build tool plugins for generating compile time safe constants for our localization strings as well as assets using swiftgen. This is working very well in Xcode 16, but fails in Xcode 26 beta 1 and beta 2 as well. The failure is specifically: unsupported configuration: the aggregate target 'Localization' has package dependencies, but targets that build for different platforms depend on it. I've reduced this to a minimal sample project, which you can find here.. To reproduce: Open the Repro workspace, that is attached in Xcode. Try to build TestyPackage. You'll see the error. I've filed this bug during WWDC week, but no feedback yet and no solution in Xcode 26 beta 2. Here's the feedback number, in case you have this too and want to file a duplicate: FB17934050. Does anyone else have this issue and perhaps a solution?

I can't access my approved and verified Apple Developer account on the web and my certificates were revoked. When I sign in with the correct email and password, I am redirected to a page asking me to enroll in the Developer Program, even though I successfully enrolled and was approved months ago. Everything with Apple Developer account had been working fine for months, and the iOS App Store app confirms that my Apple Developer Program membership subscription is still active. And if I click "Enroll Today," it says my Apple ID is already associated with an "account holder of a membership." Additionally, my macOS app certificates have been revoked without any email or explanation, and I cannot create new ones due to this issue. Also I can access my developer account via iOS and macOS apps normally, but I can't access it on the web to create new certificates. This I urgent and time sensitive for me, can someone please help?

I just downloaded Xcode26, and am trying to download the new simulator to be able to run and test my app. But the downloads folder just shows that it's stuck on "Fetching download information ..." even 15 minutes after it started. I tried restarting Xcode but didn't help. Internet connection is good. Any tips to get it working?

Problem I’m trying to implement Sign in with Apple in my application. However, when my app redirects to the Apple authorization page at: https://appleid.apple.com/auth/authorize I get an invalid_client error with no further explanation. Settings I followed this article closely: [https://developer.okta.com/blog/2019/06/04/what-the-heck-is-sign-in-with-apple#generate-the-client-secret] Steps I have completed: Created an App ID and a Service ID on Apple Developer Portal. Enabled “Sign in with Apple” for both the App ID and the Service ID. Added my domain and callback URL to the Service ID configuration. (I'm using ngrok to proxy my localhost during development.) Linked an existing private key with “Sign in with Apple” capability. My identifiers: Service ID is used as client_id Team ID is taken from the top right of the Apple Developer dashboard Key ID is from the private key associated with the App Environment My backend is built with Laravel, and I'm using the [SocialiteProvider/Apple][https://socialiteproviders.com/Apple/#installation-basic-usage] library to handle the OAuth flow. I followed the recommended method to generate a client secret (JWT) for each request, using this blog post: [https://bannister.me/blog/generating-a-client-secret-for-sign-in-with-apple-on-each-request] My .env configuration looks like this: APPLE_CLIENT_ID=com.service.paxton.stockApp APPLE_TEAM_ID=25729642DK APPLE_KEY_ID=JFP9Q53ZCY APPLE_PRIVATE_KEY=storage/AppleDev-AuthKey_JFP9Q53ZCY.p8 JWT Generation I also tested generating the JWT using the Ruby script from the Okta article: [https://developer.okta.com/blog/2019/06/04/what-the-heck-is-sign-in-with-apple#generate-the-client-secret] Here is the script I used: require 'jwt' key_file = './storage/AppleDev-AuthKey_JFP9Q53ZCY.p8' team_id = '25729642DK' client_id = 'com.service.paxton.stockObserve' key_id = 'JFP9Q53ZCY' ecdsa_key = OpenSSL::PKey::EC.new IO.read key_file headers = { 'kid' => key_id } claims = { 'iss' => team_id, 'iat' => Time.now.to_i, 'exp' => Time.now.to_i + 86400*180, 'aud' => 'https://appleid.apple.com', 'sub' => client_id, } token = JWT.encode claims, ecdsa_key, 'ES256', headers puts token This JWT validates correctly. I’ve also used Apple’s public key to verify the signature, and it passed. I verified the JWT header and payload format using this helpful article: [https://fluffy.es/how-to-solve-invalid_client-error-in-sign-in-with-apple/] Third-Party Testing To eliminate mistakes in my setup, I even tried a third-party tool featured in this YouTube video: [https://youtu.be/8v01TaX1EJA?si=0jOBGBVk0R0zbmdo] Unfortunately, the result was the same — invalid_client. Question I’ve double-checked everything I can think of: keys, claims, domain whitelist, identifiers. I even verified the JWT independently. If anyone (especially someone from Apple) can help identify the missing piece, I would be truly grateful.

I am writing to report multiple issues encountered after updating to Xcode 26 Beta, which have significantly impacted my project's compilation and functionality. My project can run normally in Xcode16.3 version, Below are the specific problems, along with the steps I took to address them and the subsequent errors that arose: Symbol Not Found Error for _NSUserActivityTypeBrowsingWeb After updating to Xcode 26 Beta, my project failed to build with the error: "Symbol not found: _NSUserActivityTypeBrowsingWeb." To resolve this, I removed the MobileCoreServices framework from the Build Settings, as it appeared to be related. However, this led to a new error, indicating that this change introduced further complications. Clang++ Error: No Such File or Directory 'OpenGLES' Following the resolution of the first issue, I encountered a new error: "iOS clang++: error: no such file or directory: 'OpenGLES'." To address this, I added the OpenGLES.framework to the Build Phases. While this resolved the clang++ error, it triggered additional errors, suggesting that the underlying issue persists or new dependencies are conflicting. Recurring XIB File Compilation Errors My project uses XIB files, and every time I attempt to compile and run, Xcode reports errors related to different XIB files. Notably, when I open the reported XIB file, no errors are displayed within the Interface Builder. After saving or inspecting the file, the compilation error temporarily disappears, only for another XIB file to trigger the same issue in the next build. This creates a repetitive cycle. I have confirmed this is not a caching issue, as I clean the build cache (Product &gt; Clean Build Folder) before each run. If I skip cleaning the cache, the OpenGLES-related error (Issue 2) reappears, indicating potential interactions between these problems. These issues have made development with Xcode 26 Beta extremely challenging, as each attempted fix seems to introduce new errors, and the XIB issue creates a persistent loop. My setup includes: Xcode Version: 26.0 beta 2 (17A5241o) macOS Version:15.4.1 (24E263)

Any idea what this message means? I assume it's coming from CloudKit, but the application seems to store and retrieve data properly.

I'm trying to compile my iPad app with Xcode 16.2 and I'm consistently getting this error message: couldn't find compile unit for the macro table with offset = 0x0 This is happening at the GenerateDSymFile step. I've tried changing the debug format from Dwarf with Dsym to Dwarf and then back again, as I've read there was a problem with generating the dsyms. But the problem persists. I've tried searching for this error and found nothing online, so apparently I'm the only one! How strange. Are there any settings or flags I can change to try to get more information about what's going wrong?

Can we use Icon Composer to drive an app icon for iOS 26 apps today? I get errors uploading a build to TestFlight internal testing about missing App icon dimensions for an iOS 26 app.

I am trying to fix a bug in my iOS app that is dependent upon date and time. Is there any way to set the actual time on the iOS Simulator to a specific date and time? I know that you can set one for the status bar, but that doesn't affect the actual date and time that is reported by the system to apps.

I'm trying to set up Xcode Cloud for the first time. When I go through the "Get Started" flow and get to "Grant Access to Your Source Code" step, when I click the "Grant Access" button, I get "This Operation Could Not Be Completed." It has the correct URL to my Github repo. Github is working fine in Xcode itself: I can push and pull changes and view repo history. I've tried: restarting Xcode rebooting the Mac Removing the Github account from Xcode and adding it back Creating a new Github personal token and removing the Github account from Xcode and using the new token to add it back I've looked through my Github settings and don't see anything that might cause an issue. I filed FB16511549 to report this. The error dialog in Xcode automatically filled the feedback fields, and says: "API Invalid status code: 500. XcodeCloudCombineAPI.XCCResponseError:1" I'm running Xcode 16.2 (16C5032a) on an M4 MacBook Pro running Sequoia 15.3.1 (24D70). Does anyone have any insights or ideas of other things to try? Thanks.

Swift assist has been announced by apple this year. I have waited Xcode 16.2 release before posting this because I was still hopping for swift assist this year but apple DIDN'T release swift assist and they haven't post anything about swift assist reported or something... What's going to happen with swift assist? Coming next year?

I would like to use devicectl to take a picture of my iPhone screen on iOS 17. So far I have successfully performed, Launching and exiting the app I created. Reboot the iPhone connected via USB etc.... I used to use libimobiledevice, but when I bought a new iPhone with iOS17, I can't do it anymore.

I implemented AppTrackingTransparency framework but Apple is rejecting the review because it seems the request is failing on iPadOS 18.3.1. which seems rare since it is working on all other devices. Has anyone faced the same issue? I have tested this in a physical iPhone with IOS 18.3.1 and in several devices using Xcode runtime simulator including iPad and iPhone in different IOS versions up to 18.2 (which I understand is the latest available in Xcode). The problem is that 18.3.1 runtime simulator is not available yet. Does anyone have more information when it will be available or what to do in these cases?
