Control and see iPhone from Mac with broken iPhone screen
Just use QuickTime Player on your Mac.


Connect the Lightning port from your iPhone to the USB to your computer.
In QuickTime select File → New Movie Recording but don't start the recording.
Next to the record button select the down arrow button, then select your iPhone. This will bring the iPhone's display screen to your Mac within QuickTime.


You don't have to record anything, you can use your non-working display and look inside QuickTime to see your screen.
