Is it possible for Swift to inherit from an lightweight generic Objective-c Class?

Question

I have two classes, the base class is in Obj-c and the subclass is in Swift.

The Obj-c class uses new XCode 7\'s lightweight generic feature defined as follows:

Answer 1

Update: As of Swift 3, Objective-C lightweight generics are imported into Swift. For more information, see

• SE-0057 Importing Objective-C Lightweight Generics
• Using Imported Lightweight Generics in Swift

Old answer: From Interacting with Objective-C APIs:

NOTE

Aside from these Foundation collection classes, Objective-C lightweight generics are ignored by Swift. Any other types using lightweight generics are imported into Swift as if they were unparameterized.

So this is not possible at present. As you can see from the "Generated Interface" assistant view, your Objective-C class is imported to Swift as

public class BaseController : UIViewController {
    public var model: SFObject!
}

This was also discussed in the Apple Developer Forum:
