Record iPhone's Screen and the audio with Quicktime? I know that I can record the phone's screen, but I want to record my phone audio too. I prefer for it not to hear the sounds around me (due to my house being loud).

I tried soundflower and loopback. I might do it wrong. And no, its not same as Screen recording, its Movie recording. I'm doing Walkthrough for the game which has voice characters.

iPhone 5C
Mac 10.11.4
You don't need any third-party service; This feature is built right into QuickTime. So just connect your iPhone to your Mac, open QuickTime, click on File > New Movie Recording (CommandOptionN), and it will show your iPhone screen. But in order to record it's audio too, click the little downward arrow next to the record button, and under "Microphone" choose "(your name)'s iPhone" (by the way if it doesn't show you your iPhone's screen make sure to select your iPhone under "Camera" too, though it should be selected by default). Then just hit record and it should do the trick.
