Oh sorry, I meant. I cant see the background in the TabView. I can see the tab view but the background show anymore in Xcode 13 target iOS 15. https://www.icloud.com/iclouddrive/0PGoBXSs0Vl1PizoP-omH6EIQ#Screen_Recording_2021-07-16_at_4.56.07_PM In this video, you can see that the background disappears when moved to another tab

Your canvas needs to be open to display the embeds. To open canvas hit Opt + Cmd + Return or Editor -> Canvas!

It seems that this is a bug in Safari 15.0. I had it to but I restarted my Mac and it was back to normal.

On the link where you got the Project from it says "Availability macOS 12.0+ & Xcode 13.0+" Update your Mac to macOS 12.0 and try again. Although, I do not recommend upgrading due to bugs I have encountered in the past few days.
