    Depreciation

    'sendAsynchronousRequest(_:queue:completionHandler:)' was deprecated in iOS 9.0: Use [NSURLSession dataTaskWithRequest:completionHandler:] (see NSURLSession.h

    Could you please update your code since this is deprecated for a while now? I have tried it my own, but couldn't get it running...

    Errors like that slow down the building process in big Xcode projects.
