Hello, Good-day,

I'm looking for some advice on integrating with an API

The API returns this.

[
    {
        "id": "act.in",
        "name": "Act In",
        "date": "2023-04-27",
        "timestamped": true,
        "date_start": "2022-10-07",
        "date_end": "2023-04-27"
    },
    {
        "id": "act.del",
        "name": "Act Del",
        "date": "2023-04-27",
        "timestamped": true,
        "date_start": "2022-10-07",
        "date_end": "2023-04-27"
    }
]

I'm using Ducky to get the codable struct and I get this

struct Unknown: Codable {
  let id: String
  let name: String
  let date: String
  let timestamped: Bool
  let dateStart: String
  let dateEnd: String

  private enum CodingKeys: String, CodingKey {
    case id
    case name
    case date
    case timestamped
    case dateStart = "date_start"
    case dateEnd = "date_end"
  }
}

And I call the API like this

    let urlAPIAppGAnalytics = "https://api.app/v1/projects/" + connectUser + "/" + connectSlug + "/collections"
    guard let url = URL(string: urlAPIAppGAnalytics) else
    {
        print("Cannot connect")
        return("40x")
    }

    var urlRequestAppGAnalyticsID = URLRequest(url: url)

    let APIheadersAppGAnalyticsID = [
        "accept": "application/json",
        "Authorization": "Token " + connectToken
    ]

    urlRequestAppGAnalyticsID.allHTTPHeaderFields = APIheadersCrawlRate
    urlRequestAppGAnalyticsID.httpMethod = "GET"
    urlRequestAppGAnalyticsID.timeoutInterval = mv.mobApiTimeout
    urlRequestCrawlRange.cachePolicy = .useProtocolCachePolicy

    let (dataAppGAnalyticsID, responseAppGAnalyticsID) = try await URLSession.shared.data(for: urlRequestAppGAnalyticsID)

    guard (responseAppGAnalyticsID as? HTTPURLResponse)?.statusCode == 200
    else {
        print("Cannot connect")
        return("40x")
    }

    let AppGID = try JSONDecoder().decode(APIAppGAnalyticsID.self, from: dataAppGAnalyticsID)

Everything compiles but my error checking returns

Type mismatch for type Dictionary<String, Any> in JSON: Expected to decode Dictionary<String, Any> but found an array instead.

Can anyone advise? Thank you!!

Glad you solved it, I would just give you a tip. Add this just above the let AppGID

let formatter = DateFormatter()
formatter.dateFormat = "yyyy-MM-dd"

let decoder = JSONDecoder()
decoder.keyDecodingStrategy = .convertFromSnakeCase
decoder.dateDecodingStrategy = .formatted(formatter)

let AppGID = try JSONDecoder().decode([APIAppGAnalyticsID].self, from: dataAppGAnalyticsID)

Now you can change the struct to

struct Unknown: Codable {
  let id: String
  let name: String
  let date: Date
  let timestamped: Bool
  let dateStart: Date
  let dateEnd: Date
}

Which will give you dates to whatever locale is and remove the need for CodingKeys (This can be done in Ducky by Property Naming Style)
