// 1. Implement URLSession:task:didReceiveChallenge:completionHandler:. (Be sure to call the completion handler with NSURLSessionAuthChallengeDisposition.PerformDefaultHandling and a nil NSURLCredential.)
// 2. Set a breakpoint in the callback + trigger an authentication challenge at runtime
// 3. In the debugger, inspect the callback's `challenge.protectionSpace` argument for the values to put in the following lines of code...
// 4. Put the following lines of code somewhere before your network requests (i.e. AppDelegate area, or other)

let basicAuthCredentials = NSURLCredential(user: "username", password: "password", persistence: .Permanent)
let foobarHttpsProtectionSpace = NSURLProtectionSpace(host: "foo.bar.com", port: 443, protocol: "https", realm: "This Probably Has A Value, Get It From The Delegate Callback", authenticationMethod: NSURLAuthenticationMethodHTTPBasic)
NSURLCredentialStorage.sharedCredentialStorage().setDefaultCredential(basicAuthCredentials, forProtectionSpace: apidevHttpsProtectionSpace)

// 5. Remove the delegate callback implementation. The credentials stored in the `sharedCredentialStorage` will be used, when required.

I feel like I've found a long-buried treasure!
