Workflow

• Identify whether the accessory uses Bluetooth, Wi-Fi, or Wi-Fi Aware and set up matching discovery properties.

• Create and activate ASAccessorySession, then handle events on the provided queue.
• Present a picker with ASPickerDisplayItem items that match the accessories you support.
• Handle .accessoryAdded to connect to the selected device; handle .accessoryRemoved and .accessoryChanged as needed.

Picker guidance
