Tuples error: type 'User11' does not conform to protocol 'Decodable' and 'Encodable' #111

Closed GanZhiXiong closed 2 years ago

GanZhiXiong commented 2 years ago 
struct User11: Codable, Defaults.Serializable {
    let name: String
    let age: String
    let languages: (String, String)
}

Can support for Tuples? or can I set the languages in the above code to not write?

This is not a problem with this package. If you remove Defaults.Serializable, it still fails. Tuples cannot conform to protocols, which is indeed an annoying Swift limitation.
