Expected Array but found Dictionary in Swift

Question

I am new to Codable in Swift, and am trying to get some data from an API (https://sportspagefeeds.com/documentation). I don't need to get all of the data from the API, just the field's specified in the model. I am getting this error when trying to run my code: typeMismatch(Swift.Array<Any>, Swift.DecodingError.Context(codingPath: [], debugDescription: "Expected to decode Array<Any> but found a dictionary instead.", underlyingError: nil))

Weirdly enough when I put the API response in a string then encode it I can successfully decode it with the same exact code. Anyone have any insight here? I am getting a 200 code from the response

code:

let request = NSMutableURLRequest(url: NSURL(string: "https://sportspage-feeds.p.rapidapi.com/games?league=NBA")! as URL,
                                                cachePolicy: .useProtocolCachePolicy,
                                            timeoutInterval: 10.0)
        request.httpMethod = "GET"
        request.allHTTPHeaderFields = headers
        
        let session = URLSession.shared
        session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
            
            if let data = data {
                do {
                    let dec = JSONDecoder()
                    dec.keyDecodingStrategy = .convertFromSnakeCase
                    let games = try dec.decode([Game].self, from: data)
                    print(games)
                    
                } catch {
                    print(error)
                    
                }
   
            }
        }).resume()

API return structure (from the link):

Here are my models:

public struct Game: Codable {
    public var gameId: String?
    public var details: Details?
    public var teams: Teams?
    public var scoreboard: Scoreboard?
}

public struct Details: Codable {
    public var league: String?
    
}

public struct Teams: Codable {
    public var home: Team?
    public var away: Team?
}

public struct Team: Codable {
    public var team: String?
    public var abbreviation: String?
}

public struct Scoreboard: Codable {
    public var score: Score?
    public var currentPeriod: Int?
    public var periodTimeRemaining: String?
}

public struct Score: Codable {
    public var away: Int?
    public var home: Int?
}

Answer 1

let see the response from api:

    "status": 200,
    "time": "2021-03-26T01:42:14.010Z",
    "games": 5,
    "skip": 0,
    "results": [....]

The response is Dictionary, but you encode it to Array of [Game] the why you receive this error. You need create more model like this

public struct GameResponse: Codable {
    var status: Int
    var time: String
    var games: Int
    var skip: Int
    var results: [Game]

}

And decode reponse to GameResponseModel:

    let games = try dec.decode(GameResponse.self, from: data)

And change your game id to Int, because it Int not String

public struct Game: Codable {
    public var gameId: Int?
    public var details: Details?
    public var teams: Teams?
    public var scoreboard: Scoreboard?
}
