<blockquote type="cite"><div>One more thing, which we realized after I sent my original email: the default implementation of many of the protocols needs to throw errors. Therefore we will add enum EncodingError and enum DecodingError to the list of new types. Those enums will have various associated values according to what is useful debug information. To preserve the ability for developers to present these errors to users with localized and user-presentable messages, when these enums are cast to NSError (e as? NSError), they will have the Cocoa error domain and a Foundation-provided code. (This is done via an extension to the enum in Foundation).<br></div>
