what are the new bluetooth changes?

The new Bluetooth changes introduced at WWDC 2024 focus on enhancing transparency and user control over Bluetooth access. Here are the key updates:

1. Updated Bluetooth Authorization Prompt:

   • The new prompt in iOS 18 clearly visualizes the data that will be made available to the app when Bluetooth access is granted. This includes showing a map indicating the current location of the device and a sample of associated devices. This helps users make an informed choice about granting Bluetooth access (What’s new in privacy).

2. Accessory Setup Kit:

   • The Accessory Setup Kit simplifies the process of managing accessories with Bluetooth and Wi-Fi. It allows apps to pair accessories with just one tap, granting both Bluetooth and Wi-Fi access if supported. This reduces the friction for users and developers, making the experience smoother and more intuitive (Meet AccessorySetupKit).
   • The accessory picker displays high-fidelity artwork and friendly names for accessories, and users can manage paired accessories directly from the settings (Meet AccessorySetupKit).

3. Privacy Enhancements:

   • iOS 18 brings focus on transparency about the types of data shared with Bluetooth access and the potential privacy risks. This includes the ability to uniquely identify a device for tracking purposes (What’s new in privacy).
   • The updated Bluetooth permission helps users only grant full access when necessary, making it easier to manage paired accessories and their permissions (What’s new in privacy).

4. Accessory Management:

   • Users can rename paired accessories, toggle access for paired apps, or remove accessories from the system. This can be done through the newly designed accessory page found in Bluetooth and Wi-Fi settings (Meet AccessorySetupKit).

These changes aim to provide better user control and transparency, ensuring that Bluetooth access is granted only when necessary and with a clear understanding of the data being shared.
