Still an issue with Xcode 15 & Swift 5.9! Non-async version gives a useless warning and async version crashes the app with :0: Fatal error: Unexpectedly found nil while implicitly unwrapping an Optional value in case where function doesn't return anything. Any hope for a fix?

Same issue. Xcode 15.3. Every second build is failing. Configuration doesn't matter, all of my projects, simulator/device, iOS 16/17.

I had same issue, but when trying to run tests. In my case the error was lying in my Package.swift file. I forgot to import a library for a target there and Xcode didn't show me corresponding error, when I fixed that, this error went away.

Same error. MacOS Sequoia Public Beta + Xcode 16 Beta 3. Every preview crashes after some time and doesn't recover until I close and reopen Xcode.

I have it too. MacOS Sequoia Public Beta + Xcode 16 Beta 3. "Frameworks, Libraries, and Embedded Content" in General project tab doesn't return any results, I need to manually re-add dependency to activate it in other menu.

I was struggling with this error for a whole day, what helped me at the end: 1 - Deleting all spm cache and derived data: rm -rf ~/Library/Caches/org.swift.swiftpm ~/Library/Developer/Xcode/DerivedData ~/Library/org.swift.swiftpm ~/.swiftpm/xcode/ 2 - Adding package with "Add Anyway" option 3 - Fully closing Xcode (cmd + q) and running this in project folder: xcodebuild -resolvePackageDependencies -disablePackageRepositoryCache Hope it helps someone! :)

Same issue. I don't even have Mac support, iPhone only.

I've got the same error couple of days ago after deleting last sandbox tester. Tried to use other browser or devices, nothing worked. What helped me: Opening "Network" tab in Chrome Developer Tools (cmd + option + i) Refreshing the page to get list of all requests Blocking this request "https://appstoreconnect.apple.com/sandbox/v2/provider/account/list?limit=50" After that I've got the page back, so I could add new tester Remove request block and the page will load the right way onwards

I have the same issue on iOS 26, when swiping back to the previous screen my view (which is marked as the source) just disappears. There's not that much time left before release, will this bug be fixed?

@DTS Engineer sorry for a long reply Reply form doesn't allow me to attach zips/folders, is this expected? Here's an example project on github: https://github.com/SubvertDev/app-icon-bug The setup is pretty basic, I've just added my .icon file to the project and deleted empty AppIcon from assets To reproduce the bug you can just archive this project on 26.0.1 and 26.1 Beta (I've tested it only on Beta 3 and RC, maybe that bug occurred before, idk) 26.0.1 xcarchive size: 1.8mb 26.1 xcarchive size: 4.2mb The main difference is Assets.car size (429KB vs 2.9MB) Here's a screenshot of Assets.car inner images difference (26.0.1 on the left and 26.1 RC on the right)

This behavior is still present after 26.1 release and on 26.2 Beta 1

@DTS Engineer I've tried Xcode 26.2 Beta 1 and the behavior is the same Filed a feedback: FB20957000 If it's indeed a bug, then I believe it would be worth mentioning about it in Xcode release notes

Well, I didn't get any notification or response in the feedback, but status did change to "Investigation complete - Works as currently designed". Is it actually? It's quite hard to believe that we've got x5-x8 size increase for bundled icons. What's the reason behind it? Is it documented somewhere? So many questions..
