Yosemite Can't start Xcode 6.1.1 with error -10699 Recently i upgrade to Yosemite,

but i can't start my Xcode, when i try to start it via terminal using

open -a xcode


i got error:

failed for the application Xcode.app with error -10699


Any ideas?
Try running the Xcode binary directly instead of using LSS.

From the CLI:

/Applications/Xcode.app/Contents/MacOS/Xcode


If something is wrong it will give you way more useful output.
