how to set request timeout in alamofire?

Question

I tried it using NSURLSession but now I want to use Alamofire.

Answer 1

This approach worked for me on swift 3

 let manager : SessionManager = {
        let config = URLSessionConfiguration.default
            config.timeoutIntervalForRequest = 15
            config.timeoutIntervalForResource = 15
        let mgr = Alamofire.SessionManager(configuration: config)

        return mgr
    }()

Got it from https://github.com/Alamofire/Alamofire#session-manager

If you want a custom timeout, either set the value on your requests, or create a custom URLSession with a custom configuration: alamofire documentation

let configuration = URLSessionConfiguration.default
configuration.timeoutIntervalForRequest = 10 // seconds
configuration.timeoutIntervalForResource = 10
let sessionManager = Alamofire.SessionManager(configuration: configuration)

//OR

var request = URLRequest(url: URL(string: "myApi.com/Api/login")!, cachePolicy: .useProtocolCachePolicy, timeoutInterval: 20)
request.httpMethod = "GET"
request.setValue("application/json", forHTTPHeaderField: "Content-Type")

Alamofire.request("https://httpbin.org/get").responseJSON { response in
    print(response)
    if let json = response.result.value {
        print("JSON: \(json)")
    }
}

Call this function in application(_:didFinishLaunchingWithOptions:) method in your AppDelegate.

func configureAlamofire() {
    Alamofire.SessionManager.default.session.configuration.timeoutIntervalForRequest = 15 // in seconds
    Alamofire.SessionManager.default.session.configuration.timeoutIntervalForResource = 15 // in seconds
}
