I like to use Window Tabs, setting them up with appropriate panels when working on SwiftUI views, writing tests, etc.
Many times now, I open a project in Xcode only to discover the main window is very small, what was expanded in the project outline is incorrect, and the window tab bar is hidden. Showing the window tab bar then just shows a single empty tab named "New Editor".
Since I didn't add any new files today or change project settings (nothing would have changed the .xcodeproj package of files), I restored a backup and that opened up a-ok. Though I first saved the bad project.
In analyzing differences between the two .xcoeproj files, I can only imagine this an issue with UserInterfaceState.xcuserstate. Though it's not practical at all to see what the changes are due to different ordering. I did notice that the bad .xcodeproj version had a massive Base64 encoded block for some IDENavigatorModeSolitary entry. The working project had a much smaller encoded block.
Anyone else run into this? For those that are now using the new JSON project files, has this still been an issue?
