Force Touch for Developers

Force click

Apps can have any button, control, or region on the screen respond to a press of stronger pressure. A Force click can provide a shortcut to additional functionality within the app.

Pressure sensitivity

Drawing and other creative apps can take advantage of the pressure-sensing capabilities of the trackpad to make lines thicker or give a brush a changing style.

Accelerators

Pressure sensitivity in the trackpad enables apps to give users greater control. For instance, fast-forward in media playback can speed up as pressure increases.

Drag and drop

Let users react to a Force click gesture while in the middle of performing a drag, for instance, to immediately open a new target for the drop.
