Manual linking IOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-spinkit and add RNSpinkit.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNSpinkit.a to your project's Build Phases ➜ Link Binary With Libraries
4. Click RNSpinkit.xcodeproj in the project navigator and go 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.
