It's worth pointing out that the example you linked with the cdecl is not showcasing the swift-java interoperability but using "raw" JNI patterns as if you would do it with C. This example does showcase the interoperability: https://github.com/swiftlang/swift-android-examples/tree/mai... you don't have to annotate or write any "weird" cdecls or really touch JNI details yourself when using the swift-java interop support https://github.com/swiftlang/swift-java

IMO the implementation (for me at least) is ... terrible. Why reach for this when it's, at the end of the day, just the exact same as NDK work in C++ but in Swift. You have to use Kotlin / Other UI setup anyways (or their fully-native example, use OpenGL to draw the screen[0]), and on top of that statically assign the package path and class name in the Swift code, while making it an external func in the kotlin code[1]. You then also get to deal with the annoyances that come up with native libs. kotlin side: /* * A native method that is implemented by the 'helloswift' native library, * which is packaged with this application. */ external fun stringFromSwift(): String swift side: @_cdecl("Java_org_example_helloswift_MainActivity_stringFromSwift") [0]: https://github.com/swiftlang/swift-android-
