xcode11 with Big Sur

Hi,
When I install Xcode11 on macOS Big Sur 11.1 , when I enter to the storyboard and I try to add constraints the windows look like empty, I means , appear the box but no named of constraint.
Someone know how to fix this.

Xcode 11 is not officially supported on Big Sur. I recommend using Xcode 12, which is officially supported on Big Sur.
