Hi! I'm running OSX Yosemite Dev preview 7 (the latest atm) and I just downloaded Xcode 6 GM Seed and installed. Although when I try to launch it an alert pops up and says that "Xcode is broken and can not be opened". I have tried rebooting the computer, re-installing the software multiple times but it still happens. Anyone who knows that this is and how to fix it?
