Added a new cacheEnabled prop to toggle Android & iOS webview caching behavior.
BREAKING CHANGE: This change makes caching enabled by default when previously there was no caching behavior which may cause unexpected behaviour changes in your existing implementations.
* fix(WKWebview): [iOS] Add shared process pool so cookies and localStorage are shared across webviews (#68)
* Add optional shared process pool
BREAKING CHANGE: useSharedProcessPool prop is set to true by default. If you want the old behavior, please use useSharedProcessPool={false}
