SmartDeviceLink (SDL) is a standard set of protocols and messages that connect applications on a smartphone to a vehicle head unit. This messaging enables a consumer to interact with their application using common in-vehicle interfaces such as a touch screen display, embedded voice recognition, steering wheel controls and various vehicle knobs and buttons. There are three main components that make up the SDL ecosystem.
- The Core component is the software which Vehicle Manufacturers (OEMs) implement in their vehicle head units. Integrating this component into their head unit and HMI based on a set of guidelines and templates enables access to various smartphone applications.
- The optional SDL Server can be used by Vehicle OEMs to update application policies and gather usage information for connected applications.
- The iOS and Android libraries are implemented by app developers into their applications to enable command and control via the connected head unit.
- To suggest new features to SDL, including the iOS library, go to the SDL Evolution github project
The mobile library component of SDL is meant to run on the end user’s smart-device from within SDL enabled apps. The library allows the apps to connect to SDL enabled head-units and hardware through bluetooth, USB, and TCP. Once the library establishes a connection between the smart device and head-unit through the preferred method of transport, the two components are able to communicate using the SDL defined protocol. The app integrating this library project is then able to expose its functionality to the head-unit through text, media, and other interactive elements.
We're still working on creating documentation for each of these individual repositories, but in the meantime, you can find more information about SmartDeviceLink on the SDL Core README and on Genivi.
See the changelog for release notes. This project uses Semantic Versioning.
See the roadmap to see what we have planned for future versions.
You can install this library using Cocoapods. You can get started with Cocoapods by following their install guide, and learn how to use Cocoapods to install dependencies by following this guide.
In your podfile, you want to add pod 'SmartDeviceLink-iOS', '~> 4.5'
. Then run pod install
inside your terminal. With Cocoapods, we support iOS 6.0+.
SDL iOS supports Carthage! Install using Carthage by following this guide. Carthage supports iOS 8+.
Tagged to our releases is a dynamic framework file that can be drag-and-dropped into the application. Dynamic frameworks are supported on iOS 8+. WARNING: You cannot submit your app to the app store with the framework as is. You MUST strip the simulator part of the framework first. Use a script such as Carthage's to accomplish this.
You can find the latest reference documentation on Cocoadocs. Install this documentation to Dash or Xcode using Docs for Xcode. On the docs page, click the 'share' button in the upper right.
If you see a bug, feel free to post an issue on the appropriate repository. Please see the contribution guidelines before proceeding. If you need general assistance, or have other questions, you can sign up for the SDL Slack and chat with other developers and the maintainers of the project.
You may want to build the sdl_core project to be able to see your application connecting if you don't have an iAP enabled head unit to test.
iOS 5 introduced the capability for an iOS application to maintain a connection to an external accessory while the application is in the background. This capability must be explicitly enabled for your application.
To enable the feature for your application, select your application's build target, go to Capabilities, enable Background Modes, and select the External accessory communication mode.
Your application must support a set of smartdevicelink protocol strings in order to be connected to smartdevicelink enabled head units. Go to your application's .plist, look at the source, and add the following code under the top level dict
. Note: This is not required if you're only testing by connected to a wifi enabled head unit, but is required for USB and Bluetooth enabled head units.

If you used CocoaPods to install the SDL SDK, you must complete the following steps to add the default lock screen resources to your project:
- Select your application's build target, go to Build Phases, Copy Bundle Resources.
- Then in the Navigator window of Xcode, go to Target's Support Files, Pods-YourProjectName, and drag and drop the SmartDeviceLink.bundle file into Copy Bundle Resources.
- After the bundle is dropped into Copy Bundle Resources check "copy items if need" from the popup box and click "Finish."
Go through the guide documentation to get started setting up your app to work with SDL!
To run tests, you will need to bootstrap the Carthage testing libraries. To do so, first install Carthage.
Then, from the root project directory, run:
carthage bootstrap --platform ios
cd ../
At this point, you can run tests from Xcode, or, if you wish to run the tests exactly as they will be run on the CI server, run:
xcodebuild -project "SmartDeviceLink-iOS.xcodeproj" -scheme "SmartDeviceLink" -sdk "iphonesimulator10.0" -destination "OS=10.0,name=iPhone 7" -configuration Debug ONLY_ACTIVE_ARCH=NO RUN_CLANG_STATIC_ANALYZER=NO GCC_INSTRUMENT_PROGRAM_FLOW_ARCS=YES GCC_GENERATE_TEST_COVERAGE_FILES=YES ENABLE_TESTABILITY=YES test
You can optionally pipe the result to xcpretty.
