Hello , I have a problem of Xcode Simulator Download,

  1. Xcode 13.0 successful installed, Macbook OS 12.0.1;
  2. got an Apple developer Account with my user name and password, free account;
  3. I go to components, and I want to download Simulator IOS 14.5;
  4. but after a long time of waiting, I got the above error message, "Xcode could not download and install simulator,... , kCFErrorDomainCFNetwork error 303.;
  5. I also tried to use sudo /Applications/Xcode.app/Contents/MacOS/Xcode , but still the same error;

What happened and how to solve this problem? thank you!
