We added support for ES6 and later in the latest 7.1.0 changes, which is awesome! The only thing missing is the support for using async/await in Titanium code.
Here is an example (taken from my sample-project):
The full sample can be found here. It is throwing an "Cannot find regeneratorRuntime" error when calling the method, which looks like a Babel error that occurs when certain transform-plugins are missing.
We use the babel-preset-env, which should already support it by having a dependency on babel-plugin-transform-async-to-generator but for some reasons it does not work.
Important to say is also that I may be doing something wrong, so let me know if thats the case!
