Alamofire HTTPS request failing

Question

I want to use Alamofire in my swift application, to get the data from server. But when I am sending request through Alamofire its always throwing an error. But if I'm using NSUrlSession with default configuration it's working.

I tried this solution but still its not working

Code which I am using

let headers = [
        "Authorization": validationHeader
    ]

    let completeUrl = kReserveBaseURL + strMyResURL
    Alamofire.request(.GET, completeUrl, headers: headers)
        .response { request, response, data, error in
            debugPrint(error)
            debugPrint(response)
    }

Below are the issues which I'm getting

    Some : Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “abc.xyz.com” which could put your confidential information at risk."

Answer 1

It looks like you are getting this error due to iOS security restricitons (Untruster server certificate on the SSL level). I would recommend to troubleshoot this by adding security exception into you app's info.plist:

<key>NSAppTransportSecurity</key>
<dict>
    <!--Include to allow all connections (DANGER)-->
    <key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

Source link: https://ste.vn/2015/06/10/configuring-app-transport-security-ios-9-osx-10-11/

After adding this you should not observe the error any more.

If it helps, you can figure out depper using this:

Especialy relevant section to you is: "Using the nscurl tool to diagnose ATS Connection Issues"

Answer 2

Its because of the security restrictions. In the info.plist add these two comments,
