NSURLRequest setAllowsAnyHTTPSCertificate to Swift

Question

What is the equivalent Swift code of the Objective-C code below?

[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[url host]];

Answer 1

SOLUTION:

Add this to file info.plist which will force ATS to accept self signed certificate:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>localhost</key>
        <dict>
            <!--Include to allow subdomains-->
            <key>NSIncludesSubdomains</key>
            <true/>
            <!--Include to allow HTTP requests-->
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <!--
            <key>NSExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/> -->
        </dict>
    </dict>
</dict>

However, as explain here this is not enough. In each class where you will use NSURLSession you have to declare the following delegate:

class LoginService: NSObject, NSURLSessionDelegate {

func URLSession(session: NSURLSession,
    task: NSURLSessionTask,
    didReceiveChallenge challenge: NSURLAuthenticationChallenge,
    completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential?)
    -> Void) {

    completionHandler(NSURLSessionAuthChallengeDisposition.UseCredential, NSURLCredential(forTrust: challenge.protectionSpace.serverTrust!))
}

...

}

And then perform something like the following:

let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()

    let urlRequest: NSURLRequest = NSURLRequest(URL: requestURL)

    let session = NSURLSession(configuration: configuration, delegate: self, delegateQueue:NSOperationQueue.mainQueue())

    /*
    dataTaskWithRequest: creates an HTTP request for the specified URL request object, and calls a handler upon completion.
    */
    let task = session.dataTaskWithRequest(urlRequest...)

This works for me. Remember that you must use Apache 2.4.x because it's the only version supporting TLS 1.2. Hope this will help.
