How to save struct to NSUserDefaults in Swift 2.0

For saving to user defaults you have a couple of options: Have the object conform to NSCoding, or implement methods that convert it to/from an NSDictionary, and save that.

Something like this:

func dictionaryFromJar() -> NSDictionary
{
   let dictionary: [AnyObject: AnyObject] = ["name": name, "amount": amount]
   return dictionary
}

I think the automatic bridging between Swift dictionaries and NSDictionary would work here, but I'm not positive. My swift is getting a little rusty. :(
