Hi @John_McCall, thanks a lot for your ideas so far. I implemented the suggestion I posted above today and it’s all building, taking some inspiration from @kateinoigakukun’s implementation in JavaScriptKit. Basically, the integration between the Android and Swift runtimes looks like it should work.
The issue is, the swift_task_enqueueMainExecutor_hook is not being called. I set that pointer to my override, add a task to the main actor (Task.detached { @MainActor in doSomething() } and the hook is never called (nor is the task of course). Does it only work if I specifically disable Dispatch while building Swift?
