how can I use bluetooth

To use Bluetooth in your app, you can leverage the new AccessorySetupKit introduced in iOS 18. This kit simplifies the process of pairing and managing Bluetooth accessories. Here are the key steps and features:

1. Discovery and Pairing:

   • You can discover and pair accessories using a single tap through the accessory picker. This picker displays the friendly name and product image of the accessory, making it easy for users to identify and authenticate the device.
   • The accessory picker can handle both Bluetooth and WiFi interfaces, allowing you to obtain all necessary communication access in one setup flow. Meet AccessorySetupKit (03:36).

2. Bluetooth Permissions:

   • In iOS 18, the Bluetooth permission prompt has been updated to provide more transparency about the types of data shared and the potential privacy risks. This helps users make informed decisions about granting Bluetooth access to your app. What’s new in privacy (17:22).

3. Managing Paired Accessories:

   • Once paired, accessories can be managed through a newly designed accessory page found in Bluetooth settings. Users can modify the accessory name, toggle access for paired apps, or remove the accessory from the system. Meet AccessorySetupKit (01:51).

4. Core Bluetooth Integration:

   • For communication with the accessory, you will still use the Core Bluetooth APIs. The AccessorySetupKit handles the discovery and authorization, while Core Bluetooth manages the actual communication. Meet AccessorySetupKit (04:28).

5. Sample Project:

   • Apple provides a sample project that demonstrates how to set up digital dice and sync roll results over Bluetooth using the AccessorySetupKit. This can be a helpful resource to see the implementation in action. Meet AccessorySetupKit (03:36).
