Xcode 13.3 required macOS 12.0 or later, but with this tips you can use it on a macOS 11 (11.6.1 for me). Xcode 13.2.1 should be installed anyway (/Applications/Xcode.app).

Install Xcode 13.3 on macOS Big Sur

1. Download Xcode 13.3 from Apple Developer Portal;
2. Unpack it and move to /Applications;
3. Right click on Xcode_13.3.app and select Show Package Contents;
4. Open Contents/Info.plist;
5. Set your current macOS version to Minimum system version (I just set 11.0).
