Alamofire HTTPS request not working for this website

Question

I am new to ios/swift devel. I am using Alamofire to get data with following piece of code:

let user = "abc"
let password = "def"

Alamofire.request(.GET, "https://wis.fit.vutbr.cz/FIT/st/get-courses.php")
        .authenticate(user: user, password: password)
        .responseJSON { response in
            debugPrint(response)
    }

However, I keep getting this error:

NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813) FAILURE: Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “wis.fit.vutbr.cz” which could put your confidential information at risk." UserInfo={NSLocalizedDescription=The certificate for this server is invalid.

I've also turned off ATS in Info.plist since it seems to be a common problem on iOS 9.0.

I get this error even when I try to retrieve data from https://www.fit.vutbr.cz Any help? I am completely lost in this.

Answer 1

It is not connected to the NSAppTransportSecurity,

Looks like this website has either self-signed or shared certificate, iOS does rejects request because it can not verify the certificate, If you are admin of the website then - use proper certificate, If there is "http" version of this site , you could use that, otherwise you have to accept this certificate, which is not available via Alamofire at the moment, you can have a look at this topic - How to implement self signed certificates in Alamofire?
