Example code here:

The downside (one of them anyway) is that you have to do all of the
Cocoa<->AE packing and unpacking yourself. If you're passing complex
data, I suggest pinching and adapting the AEMCodecs class from here:
https://bitbucket.org/hhas/appleeventbridge/src
If the scripts are part of your .app bundle, another option is to use
the AppleScript-ObjC bridge, which allows you to call AS handlers
directly from ObjC:
http://appscript.sourceforge.net/asoc.html
It's not perfect - there's no way to declare non-id signatures (you have
to wrap and unwrap C primitives yourself) and some of the AE type
bridging is problematic (NSDate/typeLongDateTime isn't automatically
bridged, and the typeObjectSpecifier mapping is defective), but for most
tasks it's the least painful option.
