On Roku, go to Settings
Select Apple AirPlay and HomeKit
Turn AirPlay On
Make sure your iPhone, iPad, or Mac is connected to the same Wi-Fi network as your Roku
Open the content you want to AirPlay
Tap the AirPlay icon on your Apple device
Select your Roku device from the list
Enter the AirPlay code if prompted
To mirror your screen on iPhone or iPad, open Control Center
Tap Screen Mirroring
Select your Roku device
To AirPlay from a Mac, click the AirPlay icon in the menu bar or in the app
Select your Roku device
If Roku does not appear, restart both devices and try again
If AirPlay still does not work, confirm AirPlay is enabled on Roku and your Apple device is updated
