This video shows you what is, in my opinion, the best way to record your screen on an IOS device. It is called Airshou, and it is not in the AppStore. I show the website, which also has many other great “apps” In the video it says that it is for IOS 9, but it can be used for IOS 10 and up, as it is constantly updating. Also, it can be a little glitchy, so after recording a video with it I would recommend immediately saving them to your camera roll.
