XCode build error: -fobjc-weak is not supported on the current deployment target

React Native 0.50.4

I try to build and run simple-fcm-client but fail. After ‘pod install’ success:

Then press build and run button in XCode, I got this error:

It works great on Android btw.

Hey,

i just ran into the same problem. i fixed it for me by increasing the ios deployment target of the nanopb target to iOS 8.0 (its 4.3 per default).

Pods Project -> target: nanopb -> iOS Deployment Target: iOS 8.0

Hope this helps
