#TODO before : Install Xcode in default location (/Applications). Run Xcode to agree license and finish setup.

xar

Put these 3 files in any folder of your choice.
Launch in terminal :
{path to unxip}/unxip {path to xip file} {path to expand in}

Example : /usr/local/bin/unxip /tmp/Xcode_12.5.xip /Applications

I did this to be able to expand xip with expired certificates.
