The Swift Package Manager is a tool for managing the distribution of Swift code and is integrated into the swift compiler.

  1. Add the package to the dependencies in your Package.swift file.

    let package: Package = .init(
        dependencies: [
            .package(url: "https://github.com/alexandrehsaad/swift-motions.git", branch: "main")
  2. Add the package as a dependency on your target in your Package.swift file.

    let package: Package = .init(
        targets: [
            .target(name: "MyTarget", dependencies: [
                .product(name: "Motions", package: "swift-motions")
  3. Import the package in your source code.

    import Motions


  1. Initiate the manager once.

    let manager: MotionManager = .shared
  2. Subscribe to the accelerometers, gyrometers and the magnetometer, and do something with the asynchronous stream of values you receive. The return type is Point representing acceleration, rotation or magnetic field respectively, and conforming to a new protocol PlottableInThreeDimensions.

    do {
        let stream: AsyncStream<Point> = try manager.subscribeToAccelerometers()
        for await data in stream {
            // Do something with the data.
    } catch let error {
        // Do something with the error.
  3. Unsubscribe from the meters.


Troubleshooting common errors

Your app must include usage description keys in its Info.plist file for the types of data it needs. Failure to include these keys cause the app to crash. To access motion data specifically, it must include NSMotionUsageDescription.
