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!

We can see from App Store Connect under TestFlight tab on the overview that our build got X number of crashes. Problem is that these crashes are not found in Crash feedback tab or not from Xcode Organizer. This problem has been ongoing for us in multiple different app builds now. Is there any suggestions what might cause this problem and how to start solving this? I'm pretty confident that these crashes happen in our network extension (NEPacketTunnelProvider). Note - We have a lot of TestFlight users and to start asking them all separately manual logs from phone might not help us here. (Settings > Privacy > Analytics & Improvements > Analytics Data). Also these crashes have not been reported to us by the users. I suspect that the reason is that the extension kicks automatically back up since we are running VPN there with on demand rules. Meaning that the users might not be able to notice the service crash or shut down because of the automatic restart. Thanks

Hey all — hoping someone here has dealt with this before. I’m testing an iOS app via TestFlight, and when I originally got access, I didn’t have an iPhone. So I signed in with my Apple ID on my girlfriend’s iPhone and used TestFlight there. Everything worked fine. Now I finally have my own iPhone (iPhone 16), downloaded TestFlight, signed in with the same Apple ID, and had the developer resend the invite. But when I tap "Open in TestFlight" from the invite email, I get this error: “Couldn’t load app because your Apple account has already been associated to this app.” The dev tried removing me as a tester and re-adding me, I’ve deleted TestFlight from both phones, rebooted, reinstalled, waited in between — still no luck. Even tried opening the invite link in Safari instead of Mail. Is there any way to get Apple to fully reset the association with the old device so I can use TestFlight on my new iPhone? Or do I really need to make a new Apple ID just to get around this? Any help would be huge — thanks!

how many devices can be deleted in one week in testflight? and can it be deleted every Monday or a week after the device is registered?

Hello Apple Support Team, We are developing a macOS application that allows users to import and view PST files (Microsoft Outlook archives). These files contain a complex, proprietary format that requires specialized parsing libraries. To achieve this, we are using Aspose Email for Java, which is currently one of the few reliable libraries that support complete PST parsing across platforms. Why we are using Java & Aspose The Aspose Email Java library provides a comprehensive API to extract mail data (including metadata, attachments, and folder structure) from .pst files. A native Swift or Objective-C alternative with full .pst parsing capability does not exist, which is why we opted for a Java-based helper module that runs in the background and communicates with the macOS app over a Unix domain socket. How we bundle it We package the AsposeEmail.jar and a custom JRE (Java Runtime Environment) created using jlink, tailored to run only our jar. This entire setup (JAR + JRE) is bundled within the Contents/Resources directory of the macOS app, and we invoke the Java runtime using standard process launch APIs from Swift. Problem during App Store Submission When we archive the app and submit it to the App Store, the validation step raises an error: ITMS-90284: Invalid Code Signing - The executable 'com.app.sample.appstore.pkg/Payload/Sample.app/Contents/Resources/custom-jre-universal/lib/cli ent/libjsig.dylib' must be signed with the certificate that is contained in the provisioning profile. ITMS-90284: Invalid Code Signing - The executable 'com.app.aample.appstore.pkg/Payload/Sample.app/Contents/Resources/custom-jre-universal/lib/cli ent/libjvm.dylib' must be signed with the certificate that is contained in the provisioning profile. When we attempt to code sign the custom JRE, especially the .dylib files inside, the runtime breaks. Java is unable to launch correctly and throws permission errors and execution failures. Alternative we thought of (On-Demand Download) To avoid the code signing issue, we decided to remove the JRE from the bundle and instead download it on demand when the user performs an action like "Import PST". However, we realized this may violate the App Store Review Guideline 2.5.2: Our use case, while not dynamically modifying features, does download and execute a Java runtime, which could be interpreted as executing new code post-installation. How can we proceed? We are looking for Apple’s guidance on the correct and compliant path forward: Is there a recommended way to bundle and codesign a custom JRE so it is accepted by the App Store? Is on-demand download of a custom runtime for a very specific parsing task permitted, assuming it doesn't modify app features but simply supports user-initiated operations? We would greatly appreciate any guidance or best practices on how to handle this situation, particularly with respect to App Store compliance. Regards, Maaz Hussain

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'm attempting to upload an updated version of our macOS app for distribution via the App Store. We've done this without issue before, but I am now receiving a warning when I upload the app via Transporter: "Cannot be used with TestFlight because the signature for the bundle at “AXON Studio.app” is missing an application identifier but has an application identifier in the provisioning profile for the bundle. Bundles with application identifiers in the provisioning profile are expected to have the same identifier signed into the bundle in order to be eligible for TestFlight." (90886) I just recently started seeing this warning when I upload our application via Transporter. Before this warning started happening, I was using the exact same process and scripts to build/package/codesign our application. NOTE: we are not using Xcode to build our application, so we can't take advantage of any codesigning/packaging automation provided by Xcode (the app is written in C#/.NET 6.0), so we are doing all build/package/codesign steps using the appropriate macOS command line utilities. Also, I have verified that the app bundle and its contents have valid signatures. Does anyone have any idea what may have changed to cause this warning, or how I might go about determining the root cause so I can fix it?

Hello there! I have developed a website (https://finnia.ch). Now I have transformed it to an app (with webview). If anyone would like to check it out and test it here is the link: https://testflight.apple.com/join/hmyDw74t It is a administration tool (not a game). Simon

I inadvertently used the build number for the version number. How can I remove these versions/builds so that i can get back to my normal versioning scheme? I am now stuck using a version number of 110 instead of a build number of 110.

Dear Experts, What is the current best practice for build numbering? I ask because I am aware that when exporting an archived app for upload I am now asked if I want Xcode to manage the build number for me. In the past I have set a build number in the Info.plist, often based on the date, e.g. 2.4.20230218. Now, I am asked if I want that to be replaced by something like 2.4.7 (if I recall correctly). So far I've answered No. Previously I have searched for automatic build numbering and I've found web pages that suggest adding a script to the build process that automatically increments the build number in the info.plist, or similar. I've not tried to implement that myself. In some of my apps, I have code that needs to know the full version at compile time (e.g. app receipt validation). How would that interact with the new feature? Thanks, Phil.

I'm using App Store Connect API to automate onboarding/off-boarding user invitations for my team members when they start working on my app. Once devs join the team, I'd like to invite them to the specific app's beta test group. This requires some additional work after the user has joined the team because unlike visibleApps, there's no way to initially indicate the beta test groups that a user should have access to. One challenge I'm finding is that people don't immediately join the team on time so polling feels a bit excessive/wasteful. Is there some recommended mechanism for adding users to the internal test flight group, or is there a way to trigger a webhook when the list of users is updated. I noticed that there's a new /v1/marketplaceWebhooks API so I imagine this is the recommended format for registering callbacks. Any assistance here would be greatly appreciated.

I try adding people as Sandbox Testers to my App, but Apple keeps saying that they already exist on the team, even though they're not. It always show "A user with this email address already exists on the team" It keeps happening with every address I try.

macOS app builds that I have uploaded today (UTC afternoon time) through Xcode are not showing. If I try to upload the same build using Transporter, it complains that it already exists. So, I know the build is there. It's just that the builds are not showing in App Store Connect for this app. There have been some problems earlier today but according to the status page they are apparently resolved.

We have an existing app - "Pluralsight: Learn Tech Skills" which is built for mac using mac catalyst. The latest version here is 3.59.0. We are shifting to "Mac (Designed for iPad)" destination instead of catalyst. The build with this change, uploaded from xcode with version 3.60.0, is not visible under macOS/iOS tab under macOS testflight app. Also we are not able to see "iPhone and iPad Apps on Apple Silicon Macs" section under "Pricing and Availability" page. We believe that this needs to be enabled for the mac app built with "Mac (Designed for iPad)". Please help out.

My company has been sharing the redeem code to the company domain email address and allow staff to redeem the app with their personal Apple ID. However, we found that the redeem code is failing and claiming the Apple ID doesn't match the one associated with the invitation. I cannot find the documentation for this change, may I know if this is something permanent?

We have an iOS app which is currently available in AppStore. Now we are enabling Mac Catalyst support for the Mac users. As our app is contains In App purchases and it is working fine in iOS devices. But when we try to purchase subscriptions from Mac Catalyst app using TestFlight, it gives the error “Your account is not valid for use in the U.S. store. You must switch to the Japan store before purchasing.” Then after we have checked an AppStore region and the region is already Japan. Any assistance would be appreciated.

Hello, I'm sure I've probably missed a checkbox somewhere.. I have a mulitiplatform app, when building from Xcode, and not using the testing config, both iOS and macOS show the correct App Store currency.. When I distribute a build through TestFlight, my Mac version shows a different country/currency price (the US one). I can't find anywhere to change this. My Mac is signed into the same sandbox account as my iOS device. Can anyone help?
