title: React native Invariant Violation: Callback with id 2 error
body: <p>I'm getting an error on my iOS simulator when I'm in Chrome debug mode, it says: Invariant Violation: Callback with id 2: RCTAppState.getCurrentAppState() not found. Any ideas what this might be related to? I've tried stripping down my pages to the bare minimum but it hasn't resolved the error.</p>
