Build error on iOS after installing react-native-safe-area-context

Getting this error after installing the library for the first time and trying to build the project on xcode. it worked perfectly on android. I’m using RN 0.59.9

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_RNCSafeAreaProvider", referenced from:
      objc-class-ref in libRNCSafeAreaContext.a(RNCSafeAreaView.o)

I also ran into this issue. I am on RN 0.59 (still).

I was able to fix it my manually linking off of the files in the SafeAreaView.xcodeproj in my main Xcode project. I simply selected every Objective-C file inside the node_modules/react-native-safe-area-context/ios/SafeAreaView folder. For some reason it only had two of the files included, when there are many more.

I’m happy to create a pull request if this is a solution desired in the library 😄

bah. it turns out it things have been a bit unstable with other libraries breaking ‘randomly’ too. i ended adding a step in my pipeline to find and replace any dependency React by React-Core and it seems to have improved matters. the command is
$ find ./node_modules -name \*.podspec -exec sed -i '' "s/s.dependency.*['\"]React[\"']/s.dependency 'React-Core'/g" {} \; HTH
