build failed 

this is what I see, when I do 'react-native run-ios', idk what am doing wrong

I cloned the branch, did as it said in d readme

Error: Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/NativebaseKitchenSink.app/Info.plist
Print: Entry, ":CFBundleIdentifier", Does Not Exist
