macOS Xcode 4 ASOC Search Bar

[BaldwinSoft]

Hi Guys,

While in the middle of working on an application I decided to upgrade to xcode 4. However, I soon learned that Xcode 4 no longer supports applescript applications, so I made the switch over to an ASOC application. Everything has went well expect for the search bar; I can't for the life of me get the search bar to take the text entered and put it into a variable. Any help to get this sorted out would be much appreciated.
Thanks,
Ian
