I created some AppleScripts that allow you to control some basic Perforce functionality in Xcode4, which was lost when Apple released the latest version of their IDE.

Perforce actually published a way of checking out files using the Behaviors functionality in Xcode (Xcode and P4), but I wanted a little more.

Note, these scripts are a work in progress. If you happen to make improvements, let me know so that those changes can be shared with the community.

You can download the AppleScripts here: xcode_p4_applescripts

Update
The AppleScript files are also being hosted on the public Perforce swarm forum, located here: Perforce Public Swarm Server

Update 2013-11-06
I updated the AppleScripts to work with Xcode5 only and added a couple of new scripts.

The new applescript files are referenced in post Perforce and Xcode5

A note about performance

On a multi-core Mac, running 10.8, I ran a test to compare the speed differences of incrementing or decrementing a value with no-locks, atomics and finally, a mutex lock.

The no-lock is the baseline, and here is the difference in speed with the later 2 items:
Atomics: 3X slower on the same thread
Mutex: 7X slower on the same thread

Hmmm…
