So, after installing Xcode 13 beta I found out that Nav bar in NavController is now transparent by default. And the only appear if you have something srollable in the scene. Is there a way to return default (iOS14) presentation of nav bar, so that it is always gray on top of the container view? P.S. no matter what settings I toggled in IB, visuals remained the same.

After launching Xcode 13 beta, I tried opening a project that is based on storyboards. Xcode couldn't load it at first, but when it did, storyboards were pitch-black with no visible elements. And an error popped out: "An internal error occurred. Editing functionality may be limited." I thought that maybe it has something to do with a project being developed in an earlier version of Xcode, so I created a new one. Nothing changed. What's more, when I tried launching simulator (any, really), black screen welcomed me, as if OS didn't launch. I am running an M1 MBA on Big Sur 11.4
