React-Native iOS App Build Failure - Print: Entry, ":CFBundleIdentifier", Does Not Exist

Question

I am running a react-native app on my local Mac OS X El Capitan machine. I have installed the required dependencies, but the app is still not launching in iOS simulator.

Here is the output:

** BUILD FAILED **


The following build commands failed:
    Ld build/Build/Products/Debug-iphonesimulator/F8v2.app/F8v2 normal x86_64
(1 failure)

An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=22):

The bundle identifier of the application could not be determined.
Ensure that the application's Info.plist contains a value for CFBundleIdentifier.

Run react-native upgrade and overwrite all iOS files. That did it for me.
