React-native-fbsdk: Error code 308 after xcode update

[justin808]

After the recent xcode update, we can no longer use the simulator to login:

error   NSError *   domain: @"com.facebook.sdk.login" - code: 308   0x000060800024f330

Direct device installs seem OK.

I'm using 0.3.0.

We tried:

1. simulator reset
2. remove FB permissions on user
3. debugging in xcode (is there some way to get symbols or source code? we quickly end up in assembly code)

@justin808 http://stackoverflow.com/a/38877600/5526221 - That answer worked for me. I needed to enable keychain access.

OMG! Turning on "Keychain Sharing" under "Capabilities" seems to have magically fixed this issue. Any downside to doing this?
