You can mirror your iPhone screen to a Mac with QuickTime and a Lightning to USB cable.
You can even record whatever you're doing on your phone when you're screen mirroring from iPhone to Mac.
Quick tip: When screen mirroring from iPhone to Mac, videos can only be streamed, but you can transfer videos between an iPhone and a Mac with AirDrop, iCloud, and iTunes.
There are various ways to mirror your iPhone to your Mac, however, the easiest way is to either use the QuickTime app on your Mac or the Screen Mirroring feature on your iPhone, which uses AirPlay.
Your phone should now be fully mirrored on your computer, in the exact shape of your iPhone screen.
