If you have recently updated you Xcode version and your favorite re-signing script suddenly does not work…then it might be possible that you have to change codesign_allocate path on your environment variable.

AppleScript certainly has its place, however, the language itself leaves a little to be desired. With that said, how can one not be intrigued by the idea of Objective-C objects in AppleScript?
The framework AppleScriptObjC allows users to write scripts with an interesting fusion of the AppleScript and Objective-C languages.

OCUDL is an experiment to bring user defined literals to Objective-C. A literal is a shorthand expression that creates a value of a certain type. For example, 25ul creates an unsigned long of 25, and @”hello” creates an NSString of hello. User defined literals bring this brevity and expressivity to our own types.
Dustin has a post that is well worth reading that describes the details of OCUDL.
