Alamofire with a self-signed certificate / ServerTrustPolicy

Question

I want to use Alamofire to communicate with my server over a https connection with a self signed certificate. My environment runs on localhost. I've tried to connect, but the response all the time looks like this:

Success: false
Response String: nil

I've done it with the following code:

import Foundation
import UIKit
import Alamofire

class MessageView: UITableViewController {

    let defaultManager: Alamofire.Manager = {
        let serverTrustPolicies: [String: ServerTrustPolicy] = [
            "localhost": .DisableEvaluation
        ]

        let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
        configuration.HTTPAdditionalHeaders = Alamofire.Manager.defaultHTTPHeaders

        return Alamofire.Manager(
            configuration: configuration,
            serverTrustPolicyManager: ServerTrustPolicyManager(policies: serverTrustPolicies)
        )
    }()

    override func viewDidLoad() {
        super.viewDidLoad()

        defaultManager
            .request(.GET, "https://localhost:3443/message")
            .responseJSON { _, _, result in
                print("Success: \(result.isSuccess)")
                print("Response String: \(result.value)")
            }
    }

}

I've created the server side certificates with this line of bash:

openssl req -x509 -nodes -days 999 -newkey rsa:2048 -keyout server.key -out server.crt

I don't know what am I doing wrong. Help would be great.

### Update ###

Here is the cURL request. In my opinion, there is no problem, or am I wrong?

curl -X GET https://localhost:3443/message -k -v

*   Trying ::1...
* Connected to localhost (::1) port 3443 (#0)

### Update 2 ###

Sorry for the late answer. Here are the two debugPrints:

Request debugPrint:

$ curl -i \
  -H "Accept-Language: en-US;q=1.0" \
  -H "Accept-Encoding: gzip;q=1.0,compress;q=0.5" \
  -H "User-Agent: Message/com.teawithfruit.Message (1; OS Version 9.0 (Build 13A340))" \
  "https://localhost:3443/message"

Result debugPrint:

### Update 3 ###

Here is the complete error with maybe an ATS problem?

nil

Answer 1

You need to add the port domain when you create your ServerTrustPolicy dictionary.

let defaultManager: Alamofire.Manager = {
    let serverTrustPolicies: [String: ServerTrustPolicy] = [
        "localhost:3443": .DisableEvaluation
    ]

    let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    configuration.HTTPAdditionalHeaders = Alamofire.Manager.defaultHTTPHeaders

    return Alamofire.Manager(
        configuration: configuration,
        serverTrustPolicyManager: ServerTrustPolicyManager(policies: serverTrustPolicies)
    )
}()
