## API for Swift

Swift is the preferred programming language for macOS, iOS, watchOS, tvOS and beyond. Swift code co-exists along side your existing Objective-C files in the same project, with full access to your Objective-C API, making it easy to adopt.

See the [API Reference for Swift](https://docs.tealium.com/platforms/ios-swift/api/) for a reference of the Tealium SDK for iOS (Swift).

## API for Objective-C

For the previous iOS (Objective-C), see the [TealiumIOS API](https://tealium.github.io/tealium-ios/) for a complete reference of the Tealium SDK.
