React Native: Command `run-ios` unrecognized

-
I have two different ReactNative-Projects: a) a project from januar 2016 b) a complete new react-native project from now (march 20th 2016) Within the new project the cli tool of react-native contains the command "run-ios" next two "run-android", but not on the older project from januar 2016.

Storage in React Native

And when I look through AsyncStorage not sure it can be handle or not million records inside it. That's why I like to know which one should I use between SQLite & AsyncStorage or some cool library out there for React Native? For that case, I recommend using Realm. It is simply much faster than AsyncStorage and SQLite. Read this and this for more info. AsyncStorage has slow runtime and has no indexing capabilities. It accepts only strings as its value and you need to serialize data before inserting and deserialize when reading. So it's not good for large amount of data. It also has 6MB limitation for Android devices.
