Apple does not allow screen recording apps in the App Store, so you’ll have to find a program that can do this for you. Mac users will have the easiest time recording their iPhone or iPad screens because they can use Quicktime.
The easiest way to record your iOS device’s screen on a Mac is simply to plug it in, open Quicktime, and record from there.
Step 1: Plug in your iOS device to your Mac and open Quicktime.
Step 2: Go to File > New Movie Recording.
Step 3: Click the arrow next to the Record button.
Step 4: Choose the device that you want to record.
Step 5: Click the Record button to start recording your iOS device’s screen.
