Same problem with me. I am using XCode 13 on the M1 MacBook pro. Battery draining fast. This should not happen with apple hardware using apple software.

Sorry, my bad. You were right. It's a missing class name issue. I am able to figure out identity inspector

I tried with "Clean Build Folder". No luck I tried declaring the IBOutlet and tried to connect code to storyboard. It does not connect Issue Navigator not showing any message for settings, See image
