I want to install the latest Xcode development software on my Mac, but the xip files won't open. I keep getting the following message: There was a problem while reading the contents of "Xcode_15 xip": Data is corrupted I have tried several unarchiver packages, and keep getting this message. I have also downloaded several other Xcode versions with the same result. Any idea what is going on here and/or how to fix it?
