Symbol() not a thing on Android/iOS < 9 in React Native

When using redux-saga in React Native on the Android platform, the Javascript environment doesn’t seem to support Symbols.

I fired up an older version (0.3.3) of redux-saga and replaced all the Symbol() calls with strings and everything worked great.

In the later codebases (0.5.0), Symbols are used much more for iterators and stuff.

Was wondering if you’d had any thoughts about perhaps supporting execution environments without Symbol() support.

I haven’t dug into why it isn’t available, but I can if you need more context.

Thanks! 😃

You include import babel-polyfill at the top of your entry point file. Like in the examples

https://github.com/yelouafi/redux-saga/blob/master/examples/counter/src/main.js#L2

[skellock]

npm install es6-symbol --save

index.android.js & index.ios.js

import 'es6-symbol/implement'

Just until either the React Native polyfill works or Symbols get removed from redux-saga.
