How to implement screen recording with audio in iOS programmatically?

Question

I have a requirement where I have screen recording with audio as well. I have done some Google and got to know about how can we implement screen recording but I am wondering how to save audio while screen recording.

Is there any possibility that we can merge the video and audio and then save the final data on disk?

But I am not sure that will it be feasible because there will be difference in syncing with audio and video frames.

For screen recording I got a link of ScreenCaptureView which actually lets you save the screen recording.

On iOS9 there is ReplayKit it's a framework that can be used to make screen recording on video games. It seems that you can use also for common screen capture.
For lower platforms it's a kind of big deal, video screen capturing exists but is a private framework ( I guess IOSurface). There are some work arounds as in this project , basically it starts to grab sigle screenshot and append them into a movie file, without audio
