# init() Creates a new event loop with a default backend configuration. ``` init() ``` ## Discussion Calls libevent’s `event_base_new()` internally. The backend (kqueue / epoll) is selected by libevent based on the host OS; swift-event does not override this selection. Traps (via `fatalError`) if `event_base_new()` returns `NULL`, which indicates catastrophic allocation failure. This behavior matches libevent’s own C-side expectations and avoids propagating a `try?` through every consumer.
