Xcode 26 only opens code files, not Storyboard, Plist, Assets, or others

Has anyone else discovered that Xcode 26 will not open any files that aren’t code? None of my project’s Storyboard, Launch Screen, Assets, built targets, Info plist will open when I click them in the Project Navigator… I just get a blank white screen in the main pane. They still exist, however: I can build my project just fine, using the pre-existing configurations and Storyboard.



I’ve discovered a workaround, such as it is: I can open my project back in Xcode 16 to edit my Storyboard, and then open it once again in Xcode 26 to build the project. This works, but as you can imagine, it’s a PITA. I’m also not able to access any Xcode 26 improvements to the Interface Builder, if there are any.



Has anyone else experienced this? Or even fixed it? I can report it as a bug but I'm surprised that I haven't even found anyone else encountering this yet.
