I'm installing on OS X El Capitan 10.11.4. There is already an Xcode 7.3 successfully installed on same system.
I've referred this link but none worked.
Per the release notes for Xcode 8 beta, the .xip file can only be extracted on OS X 10.11.5 or newer:
Expanding Xcode beta’s .xip requires macOS version 10.11.5 or later. Attempting to expand the archive on earlier versions of macOS will result in an error. (26756225)
