_Very_ basic protocol to handle conversions between Model objects and Dictionaries. Model -> Dictionary has a default implementation provided for simple 1:1 non-nested Models - Will likely adapt this into a lib at some point

DictionaryConvertable.swift

protocol DictionaryConvertable {
    static func fromDictionary(dictionary: [String: Any]) throws -> Self
    func toDictionary() -> [String: Any]
}

extension DictionaryConvertable {
    func toDictionary() -> [String: Any] {
        let mirror = Mirror(reflecting: self)
        return mirror.children.reduce([:]) { result, child in
            guard let key = child.label else { return result }
            return result + [key: child.value]
        }
    }
}

func + <K>(left: [K: Any], right: [K: Any]) -> [K: Any] {
    var result = [K: Any]()
    [left, right].forEach { dict in
        dict.forEach { result[$0.0] = $0.1 }
    }
    return result
}
