If you’re like most people, you probably have a screen on your iPhone that you can see and use. But if you want to mirror your screen on an iPhone 11, there are a few things you need to do. First, make sure that your phone is connected to the internet and that it’s running iOS 11.2 or later. Second, open the Settings app and select Mirroring from the left hand side of the screen. Third, choose how much space will your mirroring require on your phone. Finally, choose whether or not to include other apps in the mirroring process. If all goes well, your iPhone 11 will start mirroring its contents onto your computer’s screen automatically. If something goes wrong - for example if you don’t have enough space on your computer - then you’ll need to open up a Finder window and drag and drop files onto the iPhone 11’s screen so that they’re mirrored correctly.
