Tested in Swift 2.2

func loginButton(loginButton: FBSDKLoginButton!, didCompleteWithResult result: FBSDKLoginManagerLoginResult!, error: NSError!) {
        print("User Logged In")
if ((error) != nil)
        {
            // Process error
        }
        else if result.isCancelled {
            // Handle cancellations
        }
        else {
            // If you ask for multiple permissions at once, you
            // should check if specific permissions missing
            if result.grantedPermissions.contains("email")
            {
                // Do work
                getUserData()
            }
        }}

func getUserData()
{
    if ((FBSDKAccessToken.currentAccessToken()) != nil)
    {
        let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "email, name"])
        graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in

            if ((error) != nil)
            {
                // Process error
                print("Error: \(error)")
            }
            else
            {
                print("fetched user: \(result)")
                let userName : NSString = result.valueForKey("name") as! NSString
                print("User Name is: \(userName)")
                let userEmail : NSString = result.valueForKey("email") as! NSString
                print("User Email is: \(userEmail)")

            }
        })
