No a need for a screen recorder compatible for iOS has been a long standing issue. I believe I have found an easy, free and reliable screen recorder.
Below is the link for the screen recorder and steps to install;
hit download and wait for the app to download
once the app is downloaded go to settings → general → profile and device management → West Air Co → Trust developer → verify app
return to your ne verified app and you’re ready to go
hit record (big button)
once you’re done just hit stop then it will be saved to your device’s camera roll
There are some problems;
Recording for over 1 minute requires a small premium fee but unless you are planning on filming long flights I don’t see a problem.
This app requires ZERO modifications or jailbreak but works flawlessly and is COMPLETELY SAFE from my experience
