I'm running a 2015 MacBook Air with 128 GB of storage. Even after a full erase, the Xcode says that it's too big to unpack, however, I can install the one from the App Store (about 11 GB), and over the next few hours, it gradually grows in size to about 90 GB, giving you plenty of time to move it to an external drive. Also, consider changing your username on the forums 😝
