I am first time developing app for CarPlay iOS.
Where I am fetching list of stations to be played on CarPlay radio.
Following is the JSON response….

I am using Codable protocol to Parse the data.
Following is my protocol.
struct RadioStationResponseModel: Codable {
let stations: [Station]?
let pagination: Pagination
}
// MARK: - Pagination
struct Pagination: Codable {
let totalResults, fromResult, toResult, perPage: Int?
let currentPage, lastPage: Int?
}
// MARK: - Station
struct Station: Codable {
let id: String?
let market: Market?
let name, tag, description, tagline: String?
let isExclusive, isDefault: Bool?
let startDate: String?
let endDate: EndDate?
let createdAt: String?
let updatedAt: JSONNull?
let links: Links?
let slugs: [String]?
let locations: [Location]?
let transmissions: [Transmission]?
let branding: Branding?
let brandTag: String?
let assets: Assets?
}
// MARK: - Assets
struct Assets: Codable {
let logos: Logos?
let artworks: [String]?
}
// MARK: - Logos
struct Logos: Codable {
let app: App?
let carPlay, chromeCast: [String]?
let web: Web?
}
// MARK: - App
struct App: Codable {
let landscape, portrait: [String]?
}
// MARK: - Web
struct Web: Codable {
let padded: Padded?
let trimmed: App?
let landscape, portrait: [String]?
}
// MARK: - Padded
struct Padded: Codable {
let landscape: [String]?
}
// MARK: - Branding
struct Branding: Codable {
let primaryColour, secondaryColour: AryColour?
let tertiaryColour: JSONNull?
}
enum AryColour: String, Codable {
case cf202E = "#CF202E"
case eb1C24 = "#EB1C24"
case ee7723 = "#EE7723"
case the000000 = "#000000"
case the005094 = "#005094"
}
enum EndDate: String, Codable {
case the20991231T000000000Z = "2099-12-31T00:00:00.000Z"
}
// MARK: - Links
struct Links: Codable {
let facebookURL, instagramURL: String?
enum CodingKeys: String, CodingKey {
case facebookURL = "facebookUrl"
case instagramURL = "instagramUrl"
}
}
// MARK: - Location
struct Location: Codable {
let city, state, postcode, timezone: String?
}
enum Market: String, Codable {
case genre = "genre"
case metro = "metro"
}
// MARK: - Transmission
struct Transmission: Codable {
let id: String?
let type: TransmissionType?
let streams: [Stream]?
let band: Band?
let frequency: String?
}
enum Band: String, Codable {
case am = "am"
case dab = "dab"
case fm = "fm"
}
// MARK: - Stream
struct Stream: Codable {
let id: String?
let type: StreamType?
let mimeType: MIMEType?
let url: String?
let tritonMount: String?
let bitrate: Int?
let stationID: String?
enum CodingKeys: String, CodingKey {
case id, type, mimeType, url, tritonMount, bitrate
case stationID = "stationId"
}
}
enum MIMEType: String, Codable {
case audioAAC = "audio/aac"
case audioMPEG = "audio/mpeg"
}
enum StreamType: String, Codable {
case aac = "aac"
case mp3 = "mp3"
}
enum TransmissionType: String, Codable {
case broadcast = "broadcast"
case ip = "ip"
}
// MARK: - Encode/decode helpers
class JSONNull: Codable, Hashable {
public static func == (lhs: JSONNull, rhs: JSONNull) -> Bool {
return true
}
public var hashValue: Int {
return 0
}
public init() {}
public required init(from decoder: Decoder) throws {
let container = try decoder.singleValueContainer()
if !container.decodeNil() {
throw DecodingError.typeMismatch(JSONNull.self, DecodingError.Context(codingPath: decoder.codingPath, debugDescription: "Wrong type for JSONNull"))
}
}
public func encode(to encoder: Encoder) throws {
var container = encoder.singleValueContainer()
try container.encodeNil()
}
}
This is the way I am calling my API and handling response.
let netwokService : NetworkService = DefaultNetworkService()
let request = RadioModel()
netwokService.request(request, completion: { [weak self] result in
switch result{
case .success(let radioStationResponse):
print("Radio station : (radioStationResponse)")
case .failure(let errorValue):
print("Erro : (errorValue)")
}
})
func decode(_ data: Data) throws -> RadioStationResponseModel {
let decoder = JSONDecoder()
let response = try decoder.decode(RadioStationResponseModel.self, from: data)
print("Response received :- (response)")
return response
}
But the problem here I am facing is, I am not getting second object from response.
I am able to get only first object. Pagination object I am getting as nil, but is has value in it which I need for my further work.
Can anyone please help me to understand what’s wrong I am doing.
Thank you for help in advance.
