Error: [MC] Reading from private effective user settings

This message is not an error, this is simply a (somewhat buggy) log message in the debug console stating that the app is reading from user settings. You can safely ignore it.

No Video Output and [MC] Reading from public effective user settings. Error in Swift/iOS 11

The issue is in a different function call in captureOutput. This is the new function call in iOS 11 for captureOutput in AVCaptureVideoDataOutputSampleBufferDelegate:

func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) {
    guard let uiImage = imageFromSampleBuffer(sampleBuffer: sampleBuffer) else { return }
    DispatchQueue.main.async { [unowned self] in
        self.delegate?.captured(image: uiImage)
    }
}

Notice the change between "didOutput sampleBuffer:" and "didOutputSampleBuffer sampleBuffer:"
