Xcode expand

Hello guys, I have download Xcode 12.2.xip from my developer account. I had try to expand as usually with double click but in this istance and for many time utility compression stuck and come out with an error message. I have digit a line of command in terminal but I get this message: signing certificate was "Development Update" (validation not attempted) and xcode doesnt expand. What should I do to open it. I have Macos catalina. Thanks in advance
I was having trouble with Archive Utility not expanding an xcode xip file as well. After some googling, I used

Code Block
xip -x filepath/filename.xip

(replacing filepath and filename with your path and name of course!)

This worked.
