Swift Codable with dynamic keys

Question

I have JSON structure as:

\"periods\": {
    \"2018-06-07\": [
      {
        \"firstName\": \"Test1\",
        \"lastName\": \"Test1\"
      }
            


        

Answer 1

I think the JSON shall be appended with { at the beginning and } at the end in order to be valid JSON, then you can easily extract periods with code like that:

struct Period: Decodable {
    let firstName: String, lastName: String
}

let schedule = try? JSONDecoder().decode([String:[String:[Period]]].self, from: jsonData!)
let periods = schedule?.values.first?.values
