When I want to validate the app, the following error is shown:

    for me it was just deleting these files:

    • ios/._Runner.xcworkspace
    • ios/._Runner.xcodeproj

    ._ added, were you on a non-HFS or APFS volume?

    The tool is preferring the first .xcworkspace file in the directory, but it's not ignoring hidden files.
