New AppDelegate Applescript File

Ok so my last version of Xcode I was using was 3.2.6 and now I’m working with 4.5. Went to add a new app delegate file of type Applescript and don’t see it. I used Others > Empty and just added the .applescript extension to name and made my own script delegateName block. Is this how you do it now?

That’s how you add another AS class file, yes. But you can only ever have one app delegate file.
