[__NSConcreteURLComponents queryItems]: unrecognized selector

I'm getting this error trying to run a bare project from the react-native init command, on an iOS 7.1 device.

This works on the iOS simulator, so I wonder if its an iOS compatibility issue? The Movies example app works ok on this device.

```

Are you sure you aren't using NSURLComponents anywhere? – danielbeard

NSURLComponents queryItems is only available on iOS8+ That's why you are seeing the crash.

See the docs here for more info: https://developer.apple.com/library/ios/documentation/Foundation/Reference/NSURLComponents_class/index.html#//apple_ref/occ/instp/NSURLComponents/queryItems

Setting an exception breakpoint will show you which class/method is making that call. Otherwise, it sounds like react-native is calling queryItems when it shouldn't.
