I have more than 36GB available on my Mac but cannot install XCode. How much storage do I need>
It seems to require an inordinate amount of free space to decompress, double or triple the size. Xcode 13b1 is 33 GB on my disk (although Finder seems to have lost its mind reporting the size). I needed over 100 GB free to decompress it the other day.
BTW, I don't recommend b2, as it fails to compile some Swift code that depends on CF_RETURNS_NOT_RETAINED in Obj-C headers (like AVCapturePhoto).
