About this project

# Swift UUIDV7 An RFC 9562 compliant UUID v7 data type for Swift, providing cross-platform support and integrations with popular libraries. Unlike Foundation's `UUID` (typically v4), `UUIDV7` embeds a timestamp in its most significant 48 bits, enabling ordinality and better index locality for database primary keys. ## Key Features - **Timestamp-based ordering**: Sort collections by `UUIDV7` as a sort key. - **Sub-millisecond monotonicity**: Guarantees monotonically increasing generations 100% of the time, even if the system clock changes backwards. - **RawRepresentable**: Uses a Foundation `UUID` as its raw value, with dynamic member lookup for all typical `UUID` properties. - **Library integrations** via package traits: - `SwiftUUIDV7Tagged`: Convenience initializers for `Tagged`. - `SwiftUUIDV7GRDB`: `DatabaseValueConvertible` and `StatementColumnConvertible` conformances, plus database functions. - `SwiftUUIDV7StructuredQueries`: `QueryBindable` conformance and column representations. - `SwiftUUIDV7Dependencies`: A `UUIDV7Generator` dependency. - `SwiftUUIDV7SQLiteData`: CloudKit sync compatibility via `IdentifierStringConvertible`. - **AppIntents**: Conforms to `EntityIdentifierConvertible` on Apple platforms. ## Installation Add as a Swift Package Manager dependency: ```swift dependencies: [ .package( url: "https://github.com/mhayes853/swift-uuidv7", from: "0.6.1", traits: ["SwiftUUIDV7GRDB"] ) ] ``` Or copy `Sources/UUIDV7/UUIDV7.swift` directly into your project. ## License MIT License.
