Working with Accessories

Learn about the requirements for building accessories that work well with Apple devices. Discover technologies you can use in your apps to interact with accessories built for Apple devices.

HomeKit and Matter

Allow users to communicate with and control connected accessories in their home using your app. With the HomeKit or Matter framework, you can provide ways to configure accessories and create actions to control them. Users can even group actions together and trigger them using Siri.

HealthKit

Integrate HealthKit into your health and fitness apps for iOS and watchOS to create a more seamless user experience. When a customer provides permission for your app to read and write health and activity data to their Health app, your app can deliver deeply informed health and fitness solutions.

AirPlay

AirPlay allows users to wirelessly stream content from their Apple device. Using Media Player APIs that support AirPlay, you can enrich your apps by allowing users to extend content from their Apple device to Apple TV, HomePod, or AirPlay-compatible speakers.

AirPrint

It’s easy to deliver photo and document printing in your apps without the need to download or install drivers. AirPrint is built into most popular printer models and offers a complete set of features, including full-quality output, automatic media selection, and enterprise-class finishing options.

Find My network

Let users locate your products with the Find My network. With hundreds of millions of Apple devices around the world, advanced end-to-end encryption, and industry leading security, the Find My network lets users easily locate their belongings in the Find My app with the peace of mind that their privacy is protected.

Nearby Interactions with UWB

Build apps that interact with accessories simply by being in close proximity to an Apple device that includes Ultra Wideband (UWB) chipset. Taking advantage of UWB technology lets you create more precise, directionally aware app experiences.

iBeacon

From welcoming people as they arrive at a sporting event to providing information about a nearby museum exhibit, iBeacon opens a new world of possibilities for location awareness, and countless opportunities for interactivity between devices and iBeacon hardware.

Bluetooth

Create an engaging and connected user experience by integrating Bluetooth® wireless technology in your apps and hardware accessories. And with Core Bluetooth framework, it’s easy for your apps to interact with the growing number of Bluetooth Low Energy (BLE) devices.

Game Controllers

The Game Controller framework supports a wide variety of popular controllers, such as the Xbox Series X|S Wireless Controller or the Sony PS5 DualSense Wireless Controller. Adding controller support to your game is an easy way to provide a unified experience across iPhone, iPad, Mac, and Apple TV.

CarPlay

CarPlay is the smarter, safer way for people to use iPhone in the car. CarPlay apps can provide audio, communication, and route guidance features, and help the user locate nearby services. Vehicles can integrate support for CarPlay on their primary display and show route information in their instrument cluster.
