Developers can integrate it via Core Bluetooth for distance-only use cases, or combine it with the Nearby Interaction framework for both distance and direction. The session covers API usage, accessory hardware requirements (Bluetooth 6.3, inline PCT, mode-0/mode-2 support, T_FCS ≥ 100µs), and notes that the feature requires iPhones with the N1 chip and is available in iOS 27. ## Full article daily.dev links to this article rather than hosting it.
