Research direction

Investigate how swagger codegen handles type 'object' for Objective C output. The issue reports that type 'object' is incorrectly cast as NSObject, causing JSONModel crash. A suggested fix from Restlet studio shows generation of a generic class like ASKFields. The fix likely involves modifying the Objective C mustache templates in the modules/swagger codegen/src/main/resources/objc directory. Check the current template for handling 'object' types and propose a change to generate a proper model class instead of NSObject.
