October 24, 2025 — Apple Inc. has announced the release of the Swift SDK for Android, available in nightly preview versions and accessible from Windows, macOS, and Linux.
This new SDK allows developers to build Android applications using Swift natively, expanding the language’s reach beyond Apple’s ecosystem. The announcement was made by the Android Workgroup, an open group within the Swift community responsible for driving its adoption on the Android platform.
The package includes build tools and practical examples for running Swift code directly on Android devices. In addition, an official getting started guide has been published, outlining how to set up the environment and compile a first Android app written in Swift.
Currently, more than 25% of the packages in the Swift Package Index are already compatible with Android, and the Community Showcase highlights which libraries support the new platform.
Among the SDK’s components, the swift-java project stands out — a library and code generator enabling interoperability between Swift and Java, making it easier to integrate both languages within the same application.
This initiative is part of a broader effort to expand Swift’s multiplatform compatibility. The Android Workgroup has announced that it will soon publish a vision document and a public progress board to coordinate the next steps and centralize community contributions.
This new SDK opens the door to a key advantage: the swift-java bridge will allow Swift to be integrated into existing Android apps, potentially enabling developers to reuse Swift business logic (for example, from backend or shared modules) in the future without needing to rewrite it in Kotlin.
