ExperimentCore protocol requires the implementation of layerId. There are two ways: we can either provide a default value via protocol extension or implement layerId explicitly in each confirming type. The second approach is much clearer to me.


init(from decoder: Decoder) throws {
let container = try decoder.container(keyedBy: CodingKeys.self)

id = try container.decode(String.self, forKey: .id)
key = try container.decode(String.self, forKey: .key)
status = try container.decode(Status.self, forKey: .status)
layerId = try container.decode(String.self, forKey: .layerId)
variations = try container.decode([Variation].self, forKey: .variations)
trafficAllocation = try container.decode([TrafficAllocation].self, forKey: .trafficAllocation)
audienceIds = try container.decode([String].self, forKey: .audienceIds)
