Encode struct

[igor]

Hello
I have many structs like Item
When I encode this struct I need to pick up just value field from StringField

struct Item: IModel{    
    var camera : StringField    
    var globe : StringField

    enum CodingKeys: String, CodingKey {
        case camera
        case globe
    }

    public func encode(to encoder: Encoder) throws {
        var container = encoder.container(keyedBy: CodingKeys.self)
        try container.encode(camera.value, forKey: .camera)
        try container.encode(globe.value, forKey: .globe)
    }
}

public struct StringField: IField {
    var value: String
}

You might have come across the case and can give me a hint how to automate encode function and not to write encode(to encoder: Encoder) or even CodingKeys manually for every model like Item ?

I think you instead can create custom encode(to:) and init(from:) implementations for StringField. That way, you don't need to poke into .value for all use sites, but only for the inner type.

Thank you for the hint, works perfectly

public func encode(to encoder: Encoder) throws {
    var container = encoder.singleValueContainer()
    try container.encode(value)
}
