You shouldn't need to include any of these headers from inside the engine in
this file.

I suspect there's a fancier way do this without mentioning MessagePipe directly.

+  auto request = mojo::MakeRequest<mojo::ServiceProvider>(pipe.handle1.Pass());
+  context->ios_task_runner->PostTask(
+      FROM_HERE,
+      base::Bind(CreatePlatformServiceProvider, base::Passed(request.Pass())));
+  return mojo::MakeProxy(
+      mojo::InterfacePtrInfo<mojo::ServiceProvider>(pipe.handle0.Pass(), 0u));
+}
