I found a solution here in Objective C, so I ported the code to Swift (though you'll need to test it):

class testHandler: NSObject, NSURLConnectionDelegate{

    func testURL(urlPath: String){
        let url: NSURL = NSURL(string: urlPath)!
        let request = NSMutableURLRequest(URL: url)
        request.HTTPMethod = "HEAD"
        let connection = NSURLConnection(request: request, delegate: self)
    }

    func connection(connection: NSURLConnection,
        didReceiveResponse response: NSURLResponse){
            if response is NSHTTPURLResponse{
                if (response as! NSHTTPURLResponse).statusCode==200{
                    //url exists
                }
            }
    }

}
