In this video Gemma explains how to set up switch access on an iPad with one switch, and demonstrates the main switch scanning options.  You might want to setup switch scanning on an IPad or IPhone if you are able to use a switch but struggle to use the touchscreen, mouse or have difficulty with other methods of controlling the device.

Switch scanning can be setup on other devices such as Android, Windows or Mac devices as well – this video only covers setting up switches on an IPad (IPadOS) or iPhone (iOS). Further information about switch scanning for IPadOS/iOS can be found on the apple support website.
