Swift 2 - Xcode 7.0 Cannot Access HTTPS site with unstrusted SSL Certificate

Question

Experts, I\'m a Beginner in IOS 9 / XCODE 7 / Swift 2 Development Kit

I\'m trying to create an ios app that simply route to Web Application in HTTPS protocol. Below is

Answer 1

Finally I fixed it

Xcode will reject un-trusted self signed certificates from servers by default.

we can override this Using NSURLConnection and can communicate with a self-signed server, since we have the ability to control the authentication through the additional delegate methods which are not available to a UIWebView. So using connection:didReceiveAuthenticationChallenge we can authenticate against the self signed server.

References NSURLAuthenticationChallenge Docs , @Lilo Lu's Question

I Resolved My Issue in below steps
Step 1 : Defined a NSURLConnection in viewDidLoad() method of my viewController.swift as follows

 override func viewDidLoad() {
    super.viewDidLoad()

    let siteAddress = "https://domain:8443/path/to/page"
    let url = NSURL (string: siteAddress)
    let urlRequest = NSURLRequest(URL: url!)
    let urlConnection:NSURLConnection = NSURLConnection(request: request, delegate: self)!
    myWebView.loadRequest(urlRequest)
 }

Step 2 : used NSURLConnection delegate methods

    func connection(connection: NSURLConnection, canAuthenticateAgainstProtectionSpace protectionSpace: NSURLProtectionSpace) -> Bool{
        print("canAuthenticateAgainstProtectionSpace method Returning True")
        return true
    }


    func connection(connection: NSURLConnection, didReceiveAuthenticationChallenge challenge: NSURLAuthenticationChallenge){

        print("did autherntcationchallenge = \(challenge.protectionSpace.authenticationMethod)")

        if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodServerTrust  {
            print("send credential Server Trust")
            let credential = NSURLCredential(forTrust: challenge.protectionSpace.serverTrust!)
            challenge.sender!.useCredential(credential, forAuthenticationChallenge: challenge)

        }else if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodHTTPBasic{
            print("send credential HTTP Basic")
            let defaultCredentials: NSURLCredential = NSURLCredential(user: "username", password: "password", persistence:NSURLCredentialPersistence.ForSession)
            challenge.sender!.useCredential(defaultCredentials, forAuthenticationChallenge: challenge)

        }else if challenge.protectionSpace.authenticationMethod == NSURLAuthenticationMethodNTLM{
            print("send credential NTLM")

        } else{
            challenge.sender!.performDefaultHandlingForAuthenticationChallenge!(challenge)
      }
}

and that worked !!
