Summary: At the moment the `ListView.js` `_childFrames` variable is only updated on scroll. As a consequence, `onChangeVisibleRows` won't get triggered for the initial render, nor any future render not trigered by scroll events. To fix this we need to make sure native and JS have the child frames in sync.
Summary:
@public
I've increased the warning levels in the OSS frameworks, which caught a bunch of minor issues. I also fixed some new errors in Xcode 7 relating to designated initializers and TLS security.
Test Plan:
* Test the sample apps and make sure they still work.
* Run tests.
