To Reproduce

I was on branch master, everything was working fine. I created a new branch ‘android’ and ran the android simulator, fixing a few things related to android. Then I wanted to make sure things still looked good in iPhone, so I ran to iPhone simulator and that’s when I got the bug. The screen does not crash immediately. It crashes as soon as I login. The android simulator runs completely fine though. I figured I would ‘git checkout master’ branch to pinpoint what exactly caused that error, but the error persisted on the master branch. That doesn’t make much sense to me

Expected Behavior

The iPhone simulator should run fine.

It looks like you are using an older version of React Native. Please update to the latest release, v0.59 and verify if the issue still exists.

The "Resolution: Old Version" label will be removed automatically once you edit your original post with the results of running `react-native info` on a project using the latest release.

@Blutude @cristian1703 – upgrading to the latest patch 0.59.1 fixed this issue for me.
