Launching on Xcode 10

Hey,

I am new to react-native and trying to get your project to work. I ran these commands and followed that [stackoverflow answer](https://stackoverflow.com/questions/37461703/print-entry-cfbundleidentifier-does-not-exist) for fixing the error I got at first: `Print: Entry, “:CFBundleIdentifier”, Does Not Exist`

This worked, to fix that issue. Overall I did the following:

```
npm install
react-native upgrade
react-native run-ios
```

That produced following result, which I was unfortunately unable to debug.

```
warning: the transform cache was reset.
Loading dependency graph, done.

```

Is there still a way to run your project? Should I downgrade my XCode? Any help would be greatly appreciated!
