i recently deleted xcode 6 beta 3 and installed xcode 6 beta 6
when i entered gitpush in the terminal this happened
xcrun: error: active developer path (\"/Appli
Try pasting this in the terminal:
sudo xcode-select -switch /Applications/Xcode-Beta.app
It will update the path, for the new Xcode name.
Another alternative is just changing the app name back to Xcode, this, of course, considering you don't have the current one installed.
