Summary: iOS will need to be implemented separately, but the shared C++ bits are in place. Explanation: there is currently no way for the View layer to /know/ if an UpdateState call has succeeded or failed. Generally we just assume it succeeds, but if it fails we have no way of knowing or retrying. This can cause some UI bugs. To mitigate this, I'm introducing a "failure" notification callback mechanism. The JNI bridging for this is a little complicated to avoid passing Runnable across the JNI, but it should be much simpler on iOS. In development this seems to make View components much more reliable.
