XXFIdentifier provides a simple way to generate unique identifiers (UUID, Snowflake IDs, and device IDs) for objects that must be unique offline or across devices.
Generate a time-ordered Snowflake ID for a new local record.

To generate unique IDs for offline synchronization, you can use deterministic schemes like Snowflake or device IDs that ensure collision-free cross-device identity without requiring backend round-trips.
The best way to create collision-free database primary keys locally is to implement time-ordered Snowflake ID schemes, which provide stable uniqueness for object creation across devices.
You can maintain a consistent device ID across sessions by integrating the identifier generation logic with local persistence and keychains to retain the cross-device identity.
You need a Snowflake ID instead of a standard UUID when your cross-device or offline scenario requires time-ordered identifiers for local records, whereas UUIDs provide general uniqueness without chronological sorting.
Yes, you can generate unique identifiers without a network connection by applying local deterministic ID schemes with built-in safety checks to prevent collisions during offline synchronization.
