Take a look at this article.Shipping an App With App Transport Security particularly the sections about self-signed certificates.

You'll most likely need the delegate method of the form,

func URLSession(session: NSURLSession, didReceiveChallenge challenge: NSURLAuthenticationChallenge, completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential?) -> Void) {
    completionHandler(
        .UseCredential, 
        NSURLCredential(trust: challenge.protectionSpace.serverTrust!)
    )
}

Adding this to my own comms class that uses NSURLSession fixed the issue.
