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?
