why is use_frameworks! required for pods?

[robsoden]

I'm curious why use_frameworks! is required in our podfile for iOS integration.

Adding this parameter disables Flipper in the latest react-native (which is pretty important) and also breaks several other cocoapods dependencies in our project, to the point where our app does not build if rollbar is installed.

This is required because of the RollbarCrash dependency in the rollbar-apple SDK. I have just tested a number of variations, including configurations for modular headers, and none would build correctly without also setting use_frameworks!.

I'll follow up with the rollbar-apple SDK maintainer to see if it's possible to solve this there.
