A one-time request for user permission to begin an interaction session with nearby devices.
Discussion
Before an app starts an interaction session, the system requests permission to share the user’s relative distance and direction with a nearby peer. The framework presents a prompt that displays the value of this key contained in your project’s Info.plist. Define text that explains your interaction session’s purpose to the user.
