# NSNearbyInteractionAllowOnceUsageDescription

A one-time request for user permission to begin an interaction session with nearby devices.

## Discussion

Discussion warning: Define this property in the Info.plist only for apps that deploy to iOS 14. NSNearbyInteractionUsageDescription replaces this property in iOS 15 and later. 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. For more information, see Initiating and maintaining a session.
