Summary:
Hi,
This PR Solves this issue #3083.
This PR solves the problem of default color on TabBar being always grey. Which looks great if the barTintColor is unchanged. However if we set the barTintColor to something else (like blue in example) text and icons become quite unreadable.

Commit (c206417) - Enable setting color of unselected tabs
Solves this issue with a prop (unselectedTintColor) on TabBarIOS to which you just pass a color like you can for barTintColor and tintColor.
This leaves us with a result that is on second picture. Notice the color of text on tabs.

Or change it to yellow for demonstrating purposes

Summary:
public
The +[RCTConvert UIImage:] function, while convenient, is inherently limited by being synchronous, which means that it cannot be used to load remote images, and may not be efficient for local images either. It's also unable to access the bridge, which means that it cannot take advantage of the modular image-loading pipeline.
This diff introduces a new RCTImageSource class which can be used to pass image source objects over the bridge and defer loading until later.
I've also added automatic application of the `resolveAssetSource()` function based on prop type, and fixed up the image logic in NavigatorIOS and TabBarIOS.

Summary:
TabBarItemIOS supports setting the scale for base64-encoded images using an optional scale parameter, however this was broken due to the JS code only passing the uri, not the whole source object, to the native side.
