Device, Sensors & Hardware

22 frameworks

The Device, Sensors & Hardware frameworks give apps access to the physical capabilities of Apple devices and the external accessories they connect to. They read motion, environmental, and telephony sensors, communicate over Bluetooth, NFC, Ultra Wideband, and USB, drive haptic feedback, and discover, pair, and control accessories ranging from smart-home devices to digital car keys. Together they bridge software to the hardware around it, from on-device sensing to home and automotive automation.
