## Discussion

Discussion NI suspends an interaction session when the user backgrounds the app. NI ends the suspension when the user foregrounds the app again. An app may resume a suspended session only after NI invokes this callback. To resume a session after a suspension ends, call run(_:), passing in your session’s configuration. Session suspension is a local event. The framework suspends only the user’s session when the user or system event such as a phone call backgrounds the app. However, if the app stays backgrounded for too long during a suspension, NI invalidates the session with session(_:didInvalidateWith:) and the peer user’s session invokes session(_:didRemove:reason:) with reason NINearbyObject.RemovalReason.timeout.
