`__fbBatchedBridge is undefined` when loading a project with HMR in iOS simulator

See original GitHub issue

Steps to reproduce:

Open Expo XDE
Create new tab-based project
Run on iOS Simulator (app now works)
Enable hot reload (hot reload now works)
Exit simulator
Run on iOS Simulator again

Expected result: Application will run

Actual result: App crashes with Unable to execute JS call: _fbBatchedBridge is undefined screen shot 2017-06-30 at 15 16 57

The only way to fix Expo client on simulator is to delete it from home screen and install again. Also, if you disable Hot Reload before quitting simulator, this problem will not appear. So to sum up, it really seems that exiting iOS Simulator with Hot Reload enabled is the sole trigger of this problem.

iOS Expo Client v1.18.2 is going out today (simulator and ExpoKit) and later this week (app store). It includes the aforementioned fix for this issue. Let me know if you’re still seeing any trouble here.

Tentative fix is here: https://github.com/expo/expo/commit/b383dc4add1f7112de8b67bbaaa3e96c523507cb

I’m double checking with the original author to make sure I’m not breaking something else. Assuming this is ok, I’ll ship this asap.
