Wonderful way to parse Json but way to generate URLRequest why ?? switch case case case case case imagine only 30 API I think will be a lot of cases ?? could you explain why you used switch case

responseSerializationFailed(reason: Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength)

Fatal error: RequestTaskMap consistency error: no events corresponding to task found.: file /Users/userName/iphone apps/CocoaPod/Xyloop/Pods/Alamofire/Source/RequestTaskMap.swift, line 115

switch response.result {
case .success(let value):
print("in success")
completion(.success(value))
case .failure(let error):
completion(.failure(error))
}
})
})
}

and this error came if I used AF.request, instead of requesting through session : Response could not be decoded because of error:
The data couldn’t be read because it isn’t in the correct format.

do you have any plan to update for swift 5 ?

AFTER Alamofire 5.0.0 beta.3 its ok?

Absolutely great articles, but I have a question.
It seems that the 'happy path' is handled within the project but I'm wondering how I go about handling an error that is returned from the server.

Let's say, for argument's sake, that there was an implementation that retrieves a specific article from the server, and that the user completes an action that causes a request to get an article from the API that doesn't exist. The server might respond with a 404 status code causing the failure case to get executed instead of success. The server returns an error response in the body, but Alamofire still tries to decode the response into the 'success' model, which it inevitably won't be able to do.

I would assume that creating an error response model would be in order here. Something which again conforms to decodable, but how would that be implemented within performRequest function in our APIClient?

There would, of course, be the case where the error cannot be decoded into the error model, in which case we'd have to handle this separately.

Any ideas?
Thanks!

can we add some func for each request
now you have this

        return performRequest(route: APIRouter.login(email: email, password: password))
    }

    static func userArticles(userID: Int) -> Future<[Article]> {
        let jsonDecoder = JSONDecoder()
        jsonDecoder.dateDecodingStrategy = .formatted(.articleDateFormatter)
        return performRequest(route: APIRouter.articles(userId: userID), decoder: jsonDecoder)
    }

    static func getArticle(articleID: Int) -> Future<Article> {
        let jsonDecoder = JSONDecoder()
        jsonDecoder.dateDecodingStrategy = .formatted(.articleDateFormatter)
        return performRequest(route: APIRouter.article(id: articleID), decoder: jsonDecoder)
    }

so each model we have to create this typ of func but if you can create something like this with Generic

func get<T>{...}
func post<T>{...}
func put<T>{...}
func delete<T>{...}
func performRequest {...}

here some example code
https://gist.github.com/saroar/fc5fbd0c2ac4901904ab01ad3ac20048

Since this article is “part 2” and “part 1” already was using Alamofire, you should not cover how to integrate Alamofire in this article. Rather, you should put that in part one. Also, you say Carthage is the recommended way to install — according to whom? I think most likely Cocoapods is the more popular was, though it’s debatable, and also it can be installed via Swift Package Manager. Maybe it’s better to just refer to the install guide on the Alamofire github page…

I have this error in APIClient file

hi like to ask you how i can add
this is old NetworkLayer now i am trying to use ur code

        let headers: HTTPHeaders = [
            "Authorization": "Bearer \(sessionid)",
            "X-CSRF-Token": "\(csrf)"
        ]
        return headers
    }``` in to your this project would like to help me little bit which part code will be best option to add this header part 

return AF.request(route)
.responseDecodable (decoder: decoder){ (response: DataResponse) in
completion(response.result)

How to use different urls for different api's and different enviroments

Hey man, how are you?

I'm trying to make a simple post sending some headers, the servers hits an error 400 but the response shows as success, which is really odd.

This is the code I'm using in my APIClient:

 private static func performRequest<T: Codable>(route: APIConfiguration, decoder: JSONDecoder = JSONDecoder(), completion:@escaping (Result<T>)->Void) -> DataRequest {
    return AF.request(route).responseJSONDecodable(decoder: decoder) {
        (response: DataResponse<T>) in completion(response.result)
    }
}

static func postUser(completion:@escaping (Result<BaseResult>) -> Void) {
    let jsonDecoder: JSONDecoder = JSONDecoder()
    jsonDecoder.dateDecodingStrategy = .formatted(.complexesDateFormatter)
    performRequest(route: UserEndpoint.postUser(), decoder: jsonDecoder, completion: completion)
}

What I'm trying to do is not having to pass a "BaseResult":

      struct BaseResult: Codable {
         var code: Int?
      }

This is UserEndpoint:

func asURLRequest() throws -> URLRequest {
    let url: URL = try K.ProductionServer.baseURL.asURL()
    
    var urlRequest: URLRequest = URLRequest(url: url.appendingPathComponent(path))
    
    // HTTP Method
    urlRequest.httpMethod = method.rawValue
    
    let token: String = UserDefaults.standard.string(forKey: "Token") ?? ""
    let bearerToken: String = "Bearer " + token
    let bundleId: String = Bundle.footballNow.bundleIdentifier!
    
    // Common Headers
    urlRequest.setValue(ContentType.json.rawValue, forHTTPHeaderField: HTTPHeaderField.acceptType.rawValue)
    urlRequest.setValue(ContentType.json.rawValue, forHTTPHeaderField: HTTPHeaderField.contentType.rawValue)
    urlRequest.setValue(bearerToken, forHTTPHeaderField: HTTPHeaderField.authentication.rawValue)
    urlRequest.setValue(bundleId, forHTTPHeaderField: HTTPHeaderField.bundleIdentifier.rawValue)
    
    return urlRequest
} 

Any thoughts?
Thanks

work with some apis and the majority gives ( Response could not be decoded because of error: The data couldn’t be read because it isn’t in the correct format. ) and I am sure the model is okay and I implemented it manually and with JSON model websites (jsoncafe as a example)

fixed

For success case decoders work as aspected.

But in error cases we have different json response.

How can we handle error cases?

i have issue when i try Run your project (Use of unresolved identifier 'AF')
what AF stand for ?

return AF.request(route)
