Not really a bug, just a missing element in the Swift sample code from Step 6 of the Xcode and Android Integration Guide:

usersListView?.setCallback({ (args) -> Void in { ... } }, forKey: "user_clicked")

should be

usersListView?.setCallback({ (args) -> Void in { ... }() }, forKey: "user_clicked")
