# Sprig Device Mode Expands to Kotlin, Swift, and React Native


Sprig device mode now works with all of RudderStack's mobile SDKs — Android (Kotlin), iOS (Swift), React Native — along with the legacy Android (Java) and iOS (Obj-C) SDKs. Now, `identify`, `track`, and `reset` events forward to [Sprig]({{< ref "destinations/streaming-destinations/sprig/" >}}) with identical semantics across every SDK, so you can target and present in-app surveys from whichever RudderStack SDK you use today.

## What's new

- **New Sprig integrations**: Integrations for the Android (Kotlin), iOS (Swift), and React Native SDKs that mirror the same event and identity semantics as the legacy Android (Java) and iOS (Obj-C) integrations.
- **Legacy Android and iOS upgrades**: Legacy Android is upgraded to Sprig `2.23.x` (from `2.16.1`) and legacy iOS is upgraded to Sprig `4.29.x` (from `4.22.3`). There are no RudderStack API changes. See [Sprig's changelog](https://docs.sprig.com/changelog) for details on new Sprig capabilities available in the upgraded versions.
- **Safer survey presentation**: The new integrations handle host-UI edge cases more gracefully — they wait for the main thread, fall back to `track`-only when the host view isn't ready to present, and manage view lifecycles automatically, with fewer crashes and less boilerplate on the app side.

{{< info >}}
Survey presentation still requires the host app to pass a `FragmentActivity` (Android) or `UIViewController` (iOS), including for React Native — where this integration point lives on the native side of the app.
