Set up Switch Control on iPhone
If you have physical difficulties, you can use Switch Control to operate iPhone using one or more switches. With switches, you can select, tap, drag, type, and even draw freehand. You use a switch to select an item or location on the screen, then use the same (or a different) switch to choose an action.
Add a switch
You can use any of the following sources as a switch:
An external adaptive switch: Choose a Bluetooth switch or Made For iPhone (MFi) switch that plugs into the Lightning connector on iPhone.
The iPhone screen: Tap the screen to trigger the switch.
The iPhone front-facing camera: Move your head left or right while facing the camera to trigger the switch.
Before you add an external switch, connect it to iPhone, following the instructions that came with the switch. If the switch connects using Bluetooth, pair it with iPhone—turn on the switch, go to Settings > Bluetooth, tap the switch, then follow the onscreen instructions. See Connect Bluetooth devices to iPhone.
Go to Settings > Accessibility > Switch Control > Switches.
Tap Add New Switch, then choose a source.
Assign an action to the switch.
To ensure Switch Control functions correctly, you must assign the Select Item action to at least one switch.
Choose a scanning style and customize Switch Control
You can adjust the behavior of Switch Control in a variety of ways, to suit your specific needs and style.
Go to Settings > Accessibility > Switch Control.
Tap Scanning Style, then choose one of the following:
Auto Scanning: The focus automatically moves to the next item after a specified duration.
Manual Scanning: You trigger a switch to move the focus to the next item (requires multiple switches).
Single Switch Step Scanning: You trigger a switch to move the focus to the next item; if no action is taken with a specified duration, the item with the focus is automatically activated.

Add switches and specify their function.
Create, edit, and choose recipes to temporarily assign special actions to switches.

Set whether a movement action is repeated when you press and hold a switch, and how long to wait before repeating.
Assign another action to a switch by pressing and holding the switch for a long duration.
Choose the actions shown in the Scanner Menu and the order in which they appear.
Set whether and how long you need to hold a switch down before it’s accepted as a switch action.
