Hello, Your class model does not need to be a NSObject subclass. All you need it to return an Id subclass when asked by the view. Thanks to explicit casting on some types, it can be done in a simple way: - A String value can be returned casted as NSString - An int or long value can be returned casted a NSNumber - for the other values, it depends on what you want to display. For the images, I often used named images (NSImage.ImageNamed).
Take a look at the NSNumber and NSString wrapper to see how you can take advantage of the explicit casting.
