Mirror your iPhone screen to your Keynote presentation

This week I have learned a new trick with Keynote on macOS. Using the Live Video feature you can mirror the screen of an iPad or iPhone into your presentation slides.

To use the screen mirroring in Keynote, open an existing presentation or create a new one. From the menu bar select Insert-> Live Video. By default your Facetime camera will be added to the slide deck. To change view to your iPhone or iPad screen, make sure that your device is connected to your Mac using a USB C or Lightning cable. The cable that shipped with your device is sufficient for this to work. On the right side of the Keynote window, click on the plus sign next to Live Video Sources. Give the source a name, e.g., iPhone. Select the connected iPhone or iPad from the drop down list. Click on Add. Your iPhone or iPad screen should now be mirrored to your slide deck as shown below. To make the mirrored device look like the real device, you can overlay the screen mirror with the actual device frame. During your next presentation you can now show the live screen of your iPhone or iPad without the need to leave your presentation. I think this approach can be much more convenient than switching to QuickTime or a third-party app to show your device screen during a presentation.

Bonus tip: You can also use this to mirror your Apple Watch screen. On your iPhone navigate to Settings-> Accessibility-> Apple Watch Mirroring and turn on the mirroring feature.
