 # PowerSync Swift
 
 The PowerSync Swift SDK is an extension of the [PowerSync Kotlin Multiplatform SDK](https://github.com/powersync-ja/powersync-kotlin), and uses the API tool [SKIE](https://skie.touchlab.co/) and KMMBridge to generate and publish a native Swift SDK. More details about this configuration can be found in our blog [here](https://www.powersync.com/blog/using-kotlin-multiplatform-with-kmmbridge-and-skie-to-publish-a-native-swift-sdk).
