Any feedback is greatly appreciated as its not decoding

let json = """ { "success":true, "data": [ { "sport_key":"americanfootball_nfl", "sport_nice":"NFL", "teams":[ "Kansas City Chiefs", "Oakland Raiders" ] }, {

"sport_key":"americanfootball_nfl", "sport_nice":"NFL", "teams":[ "Seahawks", "patriots" ] }]} """.data(using: .utf8)

struct Outer: Codable { let success: Bool let data: [Json]

enum CodingKeys: CodingKey {
    case success
    case data
}

init(from decoder: Decoder) throws {
    let valueContainer = try decoder.container(keyedBy: CodingKeys.self)
    success = try valueContainer.decode(Bool.self, forKey: .success)
    data = try valueContainer.decode([Json].self, forKey: .data)
}

}

struct Json: Codable { var teams: [String]

enum InnerCodingKeys:  CodingKey {
    case teams

}

init (from decoder: Decoder) throws {

    let innerContainer = try decoder.container(keyedBy: InnerCodingKeys.self)
    teams = try innerContainer.decode([String].self, forKey: .teams)
}

}

let jsonDecoder = JSONDecoder() let body = String(data: json!, encoding: .utf8) let decodedData = try jsonDecoder.decode([Outer].self, from: json!)
