Problem with SwiftUI Inspector in Xcode

Almost all of the time popup window of SwiftUI Inspector in code editor has strange render (mess of random slices of interface or even empty window). On canvas, Inspector works fine, seems like this problem only in code editor. I tried different modes (dark/light) nothing helps, sometimes its starts rendering properly after building project but its like 1 out of a 10 times. Latest Xcode (11.3.1) on Catalina. Maybe some one has this problem and solve it?

I have the same issue, and it seems to be present in the new 11.4 beta as well. Hopefully it is fixed in a subsequent release.

Make sure to report it through Feedback Assistant to give it a better chance of getting fixed.

Same issue here. 2015 MacBook Pro 15, macOS 10.15.3. I'm new to Swift, and this has definitely put a damper on my learning haha.

I have the exact same issue on Xcode 11.3.1, 2017 MacBook Pro running Catalina 10.15.3

Posting these issues here doesn't really do anything, it would be best to report these issues to Apple using Feedback Assistant.
