I can't run my react-native app on ios Xcode

Question

I'm having a real issue with running my react-native ios app. I installed Xcode (version 8.3.3) and all the other basic dependencies needed, all I did was:

    react-native init AwesomeProject
    cd AwesomeProject
    react-native run-ios

And what happens is the AwesomeProject app opens for a second then closes. I also tried running it through xcode and get the same problem, although it is atleast reporting an error of:

And I then get brought to this page with the following Thread 8: signal SIGABRT error:

->  0x112538d42 <+10>: jae    0x112538d4c               ; <+20>

I have googled a lot with regards to the NSEXCEPTION yet I still cannot seem to even run my app. Any help would be much appreciated

Apparently there's an issue with react-native 0.48.0.

You can follow the thread below, it should be fixed with 0.48.1. https://github.com/facebook/react-native/issues/15768

Edit: I can confirm 0.48.1 works fine. Update using:

npm install -g react-native-git-upgrade

react-native-git-upgrade
