# Installation

> USearch for Swift

```swift
dependencies: [
    .package(url: "https://github.com/unum-cloud/USearch", .upToNextMajor(from: "3.0.0"))
]
```

The package compiles the Swift surface only, and depends on NumKong as a source package.
SwiftPM downloads the engine prebuilt, as the release's `USearchC` XCFramework on Apple platforms and as its artifact bundle on Linux, so no C++ toolchain is needed.
A checkout builds its own with CMake and points `USEARCH_SWIFT_ARTIFACT` at it, relative to the package root, as `NUMKONG_SWIFT_ARTIFACT` points the `numkong/` dependency at its own build:

```sh
cmake --preset swift
cmake --build --preset swift
USEARCH_SWIFT_ARTIFACT=build_swift/USearchC.xcframework swift build # USearchC.artifactbundle off Apple platforms
```
