Swift

Download roastedduck-1.5.6.post2-swift-apple.tar.gz from Releases. After verification and extraction, it contains a local Swift package named DuckDBRust, exporting the familiar DuckDB product and module.

Add the extracted package as a local package dependency in Xcode, or declare it in a Swift package:

.package(path: "../DuckDBRust")

Add .product(name: "DuckDB", package: "DuckDBRust") to your target's dependencies. Then:

import DuckDB

let database = try Database(store: .inMemory)
let connection = try database.connect()
let result = try connection.query("SELECT 42 AS answer")
print(result)

Platforms and verification

The Apple XCFramework contains macOS arm64, iOS arm64 device, and iOS arm64 simulator slices. Minimum deployment settings in package metadata are build targets, not proof of execution on every OS version.

The 1.5.6.post2 package retains verified Mac and simulator 133-case receipts, encrypted-storage checks, and Mac typed checkpoint/WAL handoffs. Its final Apple archive is also checked after extraction and a fresh consumer build. Execution and provisioning on a physical iPhone or iPad remain unverified. Treat iOS device integration as experimental until tested on your own hardware. Intel Mac and Intel simulator slices are outside this preview.

Linux Swift packages are distributed separately for arm64 and amd64. Use a matching Swift toolchain and retain the package's shared library alongside your application; consult its Package.swift for runtime search paths.

The upstream package emits existing Sendable/pointer warnings in its declared language mode. Strict Swift 6 language-mode conformance is not claimed.
