Looking at WWDC .. how about that swift &lt;-&gt; cpp interop. Can we hijack that to get generic interfaces (like Flow) ?

the wwdc videos going into detail about swift aren't available yet

but presumably they're presenting <https://github.com/apple/swift-evolution/blob/main/visions/using-c%2B%2B-from-swift.md> and <https://github.com/apple/swift-evolution/blob/main/visions/using-swift-from-c%2B%2B.md>

yea I just saw the presentation, they're showing vector&lt;t&gt; ..okay now I'm thinking it might be a class so :smile:

in the forums (<https://forums.swift.org/t/report-swift-and-c-interoperability-project-progress-in-the-swift-5-8-time-frame/64941>) they say
&gt; • Disabled support for instantiating C++ class templates from Swift, as the existing implementation is incompatible with Swift's type system. Class templates specializations that are already instantiated in the imported C++ code can still be used in Swift. For example, you can use a type like `VecInt` in Swift, if you have a typealias like this one in the C++ header: `using VecInt = std::vector&lt;int&gt;;`.

regardless, I don't think that matters for Kotlin's generics since those aren't translated to C++ templates and aren't specialized

so no Flow&lt;T&gt; for me? :disappointed:

not unless Swift adds another way to do interop or Swift's own object protocol is documented well enough for Kotlin to implement and somebody does the work
