I'm trying to make a Log In Call to the backend using Alamofire 5. The problem is when I make the call I need a value to return to the Controller to validate the credentials.
So, the problem is Alamofire only make asynchronous calls so I need to make it synchronous. I saw a solution using semaphore but I don't know how implement it.
This is the solution that I found:
func syncRequest(_ url: String, method: Method) -> (Data?, Error?) {
var data: Data?
var error: Error?
let url = URL(string: url)!
var request = URLRequest(url: url)
request.httpMethod = method.rawValue
let semaphore = DispatchSemaphore(value: 0)
let dataTask = URLSession.shared.dataTask(with: request) {
data = $0
error = $2
semaphore.signal()
}
dataTask.resume()
_ = semaphore.wait(timeout: .distantFuture)
return (data, error)
}
And, this is my request code:
AF.request(request)
.uploadProgress { progress in
}
.response(responseSerializer: serializer) { response in
if response.error == nil {
if response.data != nil {
do {
try decoder.decode(LogInSuccessful.self, from: response.data!)
} catch {
do {
try decoder.decode(LogInError.self, from: response.data!)
} catch {
}
}
}
statusCode = response.response!.statusCode
}
}
