NSObjectController in object mode in Swift

Question

How do I configure an NSObjectController in object mode in Swift?

Let's say I have a class A:

class A {}

Here's what I have tried:

let oc = NSObjectController()
oc.objectClass = A.self
oc.newObject() // error

The last line produces an error:

Unrecognized selector -[Test.A init]

What am I doing wrong?

Your class needs to inherit from NSObject.

This works for me:

class A: NSObject {}

let oc = NSObjectController()
oc.objectClass = A.self
let o = oc.newObject()
