If there's no better mapping for a Swift value into an Objective-C object for bridging purposes, we can fall back to boxing the value in a class. This class doesn't have any public interface beyond being `NSObject`-conforming in Objective-C, but is recognized by the Swift runtime so that it can be dynamically cast back to the boxed type.
