Downgrade Developer Test-Device to iOS 18.7.X
Hi, I accidentally upgraded my test device (iPhone 13 mini) to iOS 26. I really need to downgrade it to 18.7.X again. It seems this isn't possible since Apple doesn't sign the .ipsw anymore. Is there really no way for a paying developer to downgrade her test devices? (Please don't tell me to use the support forums, this is a concerning a developer test device)

Regarding Launch Screens
When building an app with iOS26 beta3, I received a warning saying "Launch screens will soon be required." Does this mean that, similar to the thread below, the app might not launch in builds for iOS27 and later (including iOS27)? https://developer.apple.com/forums/thread/789004

The signature of cannot be validated and may have been compromised
I'm currently developing a Unity game for iPad and have run into a critical issue that's completely blocking me from building the project. The project uses the Mapbox SDK for Unity. Everything was working fine during today test build on the iPad. I made minor changes - just four scripts, then attempted another build. However, Xcode began showing the following error: The signature of “MapboxCommon.xcframework” cannot be validated and may have been compromised. Validation Error: The signing certificate has been revoked (CSSMERR_TP_CERT_REVOKED) This error now occurs consistently. I've tried building on a different MacBook and with a different Apple account, but the result is the same. I haven't made any changes to the Mapbox framework, nor have I updated it recently. I'm trying to determine the root cause: Is this something I've done on my end? Or is it an issue with the Mapbox framework or their signing certificate? Is there a temporary workaround that would allow me to proceed with development builds while I investigate a proper fix? Any insights or suggestions would be greatly appreciated.

Apple SDKs should provide libunwind_ext.h on macOS
(Copy pasted from FB17261080 that I submitted) Hi: Apple's SDK (libSystem.B.tbd) provides definition for multiple symbols(__unw_add_dynamic_fde / __unw_add_find_dynamic_unwind_sections ), but doesn't provide corresponding headers, available in LLVM upstream as libunwind_ext.h We need such headers to write Exception-Enabled JIT Framework for macOS

Information about legacy (new app)
Hello I developed an app for my cousin (I wrote all the code myself), but she’ll be the one managing it once it’s published. She’ll take care of the content, updates, and anything admin-related. Right now, the app uses my Firebase account and my Apple Developer account (App Store Connect), which I set up at the start of the project. I’m wondering: • Am I at risk legally or financially if the accounts stay under my name, even though I won’t be involved in the app after release? • Is it possible to migrate the project to her email, meaning transfer Firebase and the Apple Developer account to her own account, so that everything is properly under her control? Thanks in advance for any insights or experiences

Is there a way for two users to make development builds on separate accounts for one app?
Tech stack: React Native + Expo. We are using two solo developer accounts (not a business or team account). Context: Friend and I set out to make an app together. Friend created app and set it up on Apple. We worked on it together. He controlled devops (builds and submission). Friend no longer can commit to development. Wants to transfer to me. I create apple developer account. After app transfer, my phone (deviceid) underwent a 14 day soft ban preventing builds. That has since been lifted. There seems to be something in place preventing me from making dev builds on the original dev bundleid. It says it's still owned by him despite the app transfer. Bottom line: what needs to happen so 1 can make dev builds? nice to have: is there a way for us to both make dev builds under the same bundleid?

Unexpected app version in logs — does MARKETING_VERSION change dynamically?
Hello, I've encountered unexpected behavior related to version information in our app logs, and I'd like to ask for some advice. We reviewed logs collected from a user running our app (currently available on the App Store). The logs are designed to include both the build number and the app version. Based on the build number in the logs, we believe the installed app version on the user's device is 1.0.3. However, the app version recorded in the logs is 1.1.5, which is the latest version currently available on the App Store. In our project, we set the app version using the MARKETING_VERSION environment variable. This value is configured via XcodeGen, and we define it in a YAML file. Under normal circumstances, the value defined in the YAML file (MARKETING_VERSION = 1.0.3) should be embedded in the app and reflected in the logs. But in this case, the version from the current App Store release (1.1.5) appears instead, which was unexpected. We'd like to know what might cause this behavior, and if there are any known factors that could lead to this. Also, is it possible that MARKETING_VERSION might somehow dynamically reflect the version currently available on the App Store? yaml: info.plist:

Apple ID dissapears from Xcode and build is failing
I'm calling this command to export archive: xcodebuild -exportArchive -archivePath .build/XYZ.xcarchive -exportPath .build/XYZ.ipa -exportOptionsPlist Authenticator/ExportOptions.plist -quiet -allowProvisioningUpdates Here is my exportOptions file content <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>method</key> <string>app-store-connect</string> <key>signingStyle</key> <string>automatic</string> <key>teamID</key> <string>ABCD</string> </dict> </plist> Most of the time this command fail with this error: error: exportArchive No Accounts error: exportArchive No signing certificate "iOS Distribution" found What we found is that our Apple ID just disappear from Xcode and we need to add it again manually. So there are two questions here: Why Apple ID account dissapears and how I can fix this? Is there an option to not use Apple ID account in Xcode and for example to use -authenticationKeyID flags of xcodebuild? Just to mention this happens only on our CI machine and not locally.

How to create a dylib for iOS project?
I want to create a dynamic library for my iOS project, which would be loaded at runtime. In Xcode, there are templates available for creating a static/dynamic lib for MacOS. But under the iOS tab, there is only a "static library" template. So, I used the "static library" template and in its build settings I changed the Mach-O type to "dynamic library". Now after building it, I use the file command on the generated file and it tells me it is a dynamic lib. But the generated file still has .a extension, which is usually for static libs. I'm aware we can tell Xcode in build settings to change the .a extension to something else, say .dylib but this seems like a hacky way to create a dynamic library. What is the correct way? I am aware that standalone dylibs are not supported on iOS, and we need to wrap them in a framework. For my use case, the framework will literally be a wrapper, it won't have any source files of its own. It should only contain the dynamic lib generated from some independent codebase. I am not sure how to place the dylib in the framework.

Assets.car not being built as part of the archiving and distribution process
I am working on a MAUI application. When I go to archive my build to then release it, my bundle is not including the Assets.car file that apple is seemingly expecting for handling the app icons, which is leading to issues trying to publish my app. The assets are in a AppIcon.appiconset folder in my project (under Platforms>iOS>Resources) with a proper Contents.json file also in there. They are setup as a BundledResource (also have tried ImageAssets for the build type but with the same issue occurring). I am using visual studio 2022 on Windows 11 paired with a Mac (Sequoia 15.5) and Xcode 16.4. I have even tried manually compiling the asset catalog from xcode16.4 and trying to use terminal commands to have actool create the Assets.car but that runs with no files created to the output destination as well as no errors. I believe there may be an issue with actools in my Xcode copy. I have tried uninstalling and reinstalling with no luck. Any suggestions or tips?

Discrepancies in MetricKit and Xcode Organizer Data
We recently integrated MetricKit into our app; however, the 90th percentile data does not seem to match the data in Xcode Organizer. The values reported by MetricKit appear to be higher. Additionally, it looks like data for previous app versions is not being updated in Organizer as adoption of the latest version increases. Has anyone else experienced this issue? Could there be a delay in data updates for older versions in Organizer? Are there any known limitations or best practices for ensuring consistency between MetricKit and Xcode Organizer data? Any guidance would be greatly appreciated.

iOS AppPresser app logs out automatically after any period of time (Android works fine)
Hello, Thank you for taking the time to read this and hopefully helping me. https://apps.apple.com/gb/app/gdl-graded-darts-leagues/id1592502150 I created a mobile app using AppPresser that is connected to my WordPress website. The iOS app is logging users out when they close the app and go back to it. The login session does not persist, and users are forced to log in again frequently. This happens at any time period between closing and opening the app. This only happens on iOS — Android keeps the session active as expected. I don't know if I've included this post in the correct topic, sorry. Thanks again for any ideas and assistance!

Missing Apple-Hosted Background Assets info
After combing the forums and release nodes, here are some extra notes to help other developers using Apple-Hosted Background Assets. I don't promise I got this perfect, but it may help direct you. AssetPack.Status is an OptionSet (not an enum!) - Critical API detail missing from guide It's a bitmask where values can be combined 2⁰ (1) = available to download 2¹ (2) = update available 2² (4) = up to date 2⁶ (64) = downloaded Example: status value 69 = 0b1000101 = available + up to date + downloaded Use .contains() method to check specific flags AssetPack.version property - Undocumented feature Auto-assigned by App Store Connect for Apple-hosted packs Increments with each upload of same asset pack ID No file deduplication across asset packs Same file in two packs = counts twice toward 200GB limit Best practice: create separate pack for shared files Shared namespace path requirements Asset pack ID is NOT part of file path Each file must have unique relative path across ALL app's asset packs Example: Foo/10/239/414.png and Bar/10/239/414.png are distinct and won't collide Additional url(for:) bugs beyond iOS 26.1 fix iOS 26 Beta 5: "item with same name already exists" error Workaround: Request URL for directory, then manually append filename TestFlight-only availability - Major limitation not mentioned! Apple-hosted packs currently ONLY work for internal testers on TestFlight or from App Store. Won't work from Xcode until "later this year" HTTP 400 errors expected for non-TestFlight installs ba-serve port workaround URL override port bug exists on multiple device types Use ba-serve -p 443 instead of custom ports

"A software update is required" message is shown when running beta software
I'm running the latest iOS 26 beta 5 on my iPad and iPhone. Whenever I run these betas, I always get the message below telling me an update is available (whenever I plug in my devices). I'm assuming this is because the update check is detecting that I have something other than the latest production release. Obviously, it makes no sense to ask me to update to a prod build when I'm running the dev beta. Is there a way to turn this message off? Or maybe Apple could handle this situation better? Or maybe it's just a bug and I'm the only one getting this message?
