AutoAPI Swift SDK

The AutoAPI Swift SDK purpose is to help developers serialise AutoAPI data in Swift, so they wouldn't have to worry about parsing and generating the bytes themselves. The SDK is generated based on the AutoAPI spec.

Table of contents


Serialising: The library is designed to serialise AutoAPI data to and from Swift types.

Support for Updates: Updates to the AutoAPI spec (non-binary) will work with older versions of the library and the new types of data are accessible.


It's recommended to use the library through Swift Package Manager (SPM), which is now also built-in to Xcode and accessible in File > Swift Packages > ... or going to project settings and selecting Swift Packages in the top-center.
When targeting a Swift package, the Package.swift file must include .package(url: "https://github.com/highmobility/auto-api-swift", .upToNextMinor(from: "[__version__]")), under dependencies.

If SPM is not possible, the source can be downloaded directly from Github and built into an .xcframework using an accompaning script: XCFrameworkBuilder.sh. The created package includes both the simulator and device binaries, which must then be dropped (linked) to the target Xcode project.

Furthermore, when .xcframework is also not suitable, the library can be made into a fat binary (.framework) by running UniversalBuildScript.sh. This combines both simulator and device slices into one binary, but requires the simulator slice to be removed before being able to upload to App Store Connect – for this there is a AppStoreCompatible.sh script included inside the created .framework folder.


AutoAPI Swift SDK requires Xcode 11.0 or later and is compatible with apps targeting iOS 10.0 or above.

Getting started

Get started by reading the iOS AutoAPI guide in high-mobility.com.

Check out the spec for more details on the structure and logic, or some other libs generatated on that spec: Android, Elixir.


There are 3 sample apps available on Github.com to showcase usage of AutoAPI (and HMKit):

  • Scaffold
    • Demonstrates the most basic usage of AutoAPI.
  • Data Viewer
    • Tries to parse and show the AutoAPI data received from a vehicle. Limited functionality to send commands.
  • AutoAPI Explorer
    • Incorporates all the "abilities" of the previous sample apps along with more commands to send to the vehicle and takes a shot at a nice(r) UI.


We would love to accept your patches and contributions to this project. Before getting to work, please first discuss the changes that you wish to make with us via GitHub Issues, Spectrum or Slack.

The generator used to create this lib, based on the AutoAPI spec, will be open-sourced in the near future. Until then, changes to the Swift interface need to go through our private generator. If you'd like to make changes to the AutoAPI, please see here.

Releases are done by tagged commits (as required by SPM, please read more about it here and here).

Rewritten property-capability-command architecture.

  • Properties are wrapped in a new type AAProperty, with it's main accessors:
    • .value: ValueType?
    • .failure: AAPropertyFailure?
    • .timestamp: Date?
  • AACapability renamed to AACapabilityValue:
    • It's .command renamed to .capability
  • AACommand rewritten and renamed to AACapability:
    • Also conforms to AACapabilityClass
  • Outgoing commands' methods return a rewritten type AACommand (used to return [UInt8]):
    • Has .bytes accessor for getting the data to send
  • Percentage changed from UInt32 (0-100 value) to Double (0.0-1.0 value).
