| URLからデータを取得したい |
| fetchVenueを呼び出したところ |
| keyNotFound(CodingKeys(stringValue: "group", intValue: nil), Swift.DecodingError.Context(codingPath: [CodingKeys(stringValue: "response", intValue: nil)], debugDescription: "No value associated with key CodingKeys(stringValue: \"group\", intValue: nil) (\"group\").", underlyingError: nil)) |
| というエラーが出てしまい、データを取得できません。 |
| 解決方法を教えていただけないでしょうか？ |
| ```Swift |
| class Service { |
| static let shared = Service() |
| func fetchVenue(location: CLLocationCoordinate2D, completion: @escaping (Empty?, Error?) -> ()) { |
| let urlString = "https://api.foursquare.com/v2/search/recommendations?ll=\(location.latitude),\(location.longitude)&v=20160607&intent=coffee&limit=15&client_id=\(client_id)&client_secret=\(client_secret)" |
| fetchGenericJSONData(urlString: urlString, completion: completion) |
| } |
| func fetchGenericJSONData<T: Codable>(urlString: String, completion: @escaping (T?, Error?) -> ()) { |
| guard let url = URL(string: urlString) else { return } |
| URLSession.shared.dataTask(with: url) { (data, resp, err) in |
| if let err = err { |
| completion(nil, err) |
| return |
| } |
| do { |
| let objects = try JSONDecoder().decode(T.self, from: data!) |
| // success |
| completion(objects, nil) |
| } catch { |
| completion(nil, error) |
| } |
| }.resume() |
| } |
| } |
| ``` |
