To install xcode12 i must have 40GB!!! 10g for xip file and 30g for app. It‘s a disaster for the mac with only 128g. Could you optimize the xcode12 size next version? The xcode11.5 xip takes 8gb and 17gb for app. Xcode10.2 is 6gb for xip and 12gb for app. Old versions are much smaller. So i guess something can be made into download content. Hope the Apple developer team can see this.
