Storing Struct in UserDefaults

There is a post by Paul Hudson where he explains how structs can be stored in UserDefaults. He recommends converting the value to Data type first and then store it directly in UserDefaults.

Similarly for retreving, get the Data and decode it to get the desired type back

So to make it more convenient and Swifty, I have written the following extension

extension UserDefaults {
    private static let encoder = JSONEncoder()
    private static let decoder = JSONDecoder()

    func encodeAndSet<T>(_ value: T, forKey defaultName: String) where T: Encodable {
        if let encoded = try? Self.encoder.encode(value) {
            set(encoded, forKey: defaultName)
        }
    }

    open func decodedObject<T>(forKey defaultName: String) -> T? where T: Decodable {
        guard let data = data(forKey: defaultName) else {
            return nil
        }
        return try? Self.decoder.decode(T.self, from: data)
    }
}

After adding above methods to UserDefaults one can easily store Codable types in UserDefaults with just one line of code

struct Person: Codable {
    var name: String
    var age: Int
}

var john = Person(name: "John", age: 41)
UserDefaults.standard.encodeAndSet(john, forKey: "user")

let getJohn: Person? = UserDefaults.standard.decodedObject(forKey: "user")
print(getJohn) // print Optional(FR.Person(name: "John", age: 41))
