Hangs with no error

[irfaan]

Running on both simulator and device (with update to RCTDeviceUUID.m), DeviceUUID just hangs and does not log the uuid to the console. Any ideas on how to begin debugging this?

Update
I needed to perform the following steps (adapted from react-native-keyboardevents):

In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name] Go to node_modules ➜ react-native-device-uuid and add the .xcodeproj file

In XCode, in the project navigator, select your project. Add the lib*.a from the react-native-device-uuid project to your project's Build Phases ➜ Link Binary With Libraries. Select the .a file. Go to the Build Settings tab. Make sure 'All' is toggled on (instead of 'Basic'). Look for Header Search Paths and make sure it contains both $(SRCROOT)/../react-native/React and $(SRCROOT)/../../React - mark both as recursive.

Good to know you resolve the problem! In fact, that's the how React Native suggest us to add a library to the app. Please refers to here: https://facebook.github.io/react-native/docs/linking-libraries.html#content
I'll add your steps to README as troubleshooting, Thanks @irfaan
