On iOS 18.0+ simulators, tap any share link button from any app, select "Save to Files", the "Save" button is disabled.
In all previous simulator versions this works. This behavior even happens with default Apple apps like Photos.
Simulator: Version 16.0 (1037)
XCode: Version 16.1 beta (16B5001e)
macOS: 14.6.1 (23G93)

I'm seeing same thing in my own app, and tried Photos as well with same behavior.
Repro Open Photos Select a Photo Share button (lower left) Scroll to "Export Unmodified Original" Select Export Unmodified Original See "Save" button dimmed. Try to create a new folder -> Doesn't work
Same here!! I was not able to save any documents to Files! even create a new folder
I have the same issue.
I try to either drag a file to the simulator and the Save button is greyed out. also i try to download a pdf from https://www.orimi.com/pdf-test.pdf and the Save button is greyed out
Same problem.
Pressing "save to files" here: https://imgur.com/IjHDQaC

But iOS 17.5 is fine: https://imgur.com/jTru1p9
I have the same problem with iOS 18 simulators since latest update of XCode - but the problem exists only during UI testing. When I run the app regularly on the simulator, the problem does not exist. However, this is annoying as it renders the UI testing useless.
Issue still persists but not even acknowledged in release notes as "known issues"...: https://developer.apple.com/documentation/xcode-release-notes/xcode-16_3-release-notes
It's been months but no progress...
Even just opening the Files app in the simulator, trying to create a "New Folder" fails
Found the solution:
Search for "EXCLUDED_ARCHS" in "project.pbxproj" file.
If you see a line like
EXCLUDED_ARCHS[sdk=iphonesimulator*]" = "i386 arm64"
remove it. This will also solve your "laggy simulator" problem.
I can add a sharper repro condition: this is specific to cloned simulators, not UI testing itself.
Same XCUITest, same iOS 26.5 runtime, Xcode-managed parallel testing:
-parallel-testing-enabled NO): the Files save sheet works, Save enables, test passes.-parallel-testing-enabled YES (even with worker count 1, which still runs on a "Clone 1 of iPhone…" device): the save sheet opens, the filename is filled in, but the Save button is disabled from the first frame and never enables, and the document thumbnail never loads. Nothing app-side differs — the sheet is presented by SwiftUI fileExporter with a valid FileDocument.So "happens only during UI testing" in earlier replies is more precisely "happens only on parallel-testing simulator clones" — the local-storage file provider in a freshly cloned, test-hosted simulator appears unable to stage/write the document. The EXCLUDED_ARCHS workaround mentioned above doesn't apply in my case (project has no such setting).
Workaround: run the affected test classes serially on a non-cloned simulator; everything else can stay parallel.
