My coworker has just installed the Xcode 7 beta onto his OS X 10.10 machine.
Whenever he tries to build or execute a playground, he gets a popup with the message "The operation couldn’t be completed. (Cocoa error -102.)"
He also gets the following message in Console:
8/4/15 1:23:19.293 PM Xcode[813]: [MT] IDEPlaygroundDocument: Error encountered running playground: Error Domain=NSCocoaErrorDomain Code=-102 "The operation couldn’t be completed. (Cocoa error -102.)" UserInfo=0x7fdcee925780 {Error=LaunchServices: RegistrationFailed}
Can someone please help us figure out what might be going wrong here? We've tried all the obvious things (restarting, reinstalling Xcode, etc.).
The issue occurs only with Xcode 7 (latest) beta (i.e. issue does not reproduce in Xcode 6.x)
