Linker error when using ActionExtension #2

Closed shaneosullivan closed 7 years ago

I've been following the instructions for building an Action Extension with React Native at https://www.promptworks.com/blog/building-ios-app-extensions-with-react-native, and everything went fine until the ActionExtension part.

When I create ActionExtension.h and ActionExtension.m, the compilation breaks with the error:

Undefined symbols for architecture x86_64:
  "_actionViewController", referenced from:
      -[ActionExtension done] in ActionExtension.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Details: React Native version 0.48.1 XCode Version 8.3.3 I have ensured that ActionExtension.m is built for both targets, as in the instructions. The problem seems to stem from the fact that ActionExtension.m cannot see the actionViewController property that we have attempted to expose publicly.

My code, in it's current failing-to-build state is on Github at https://github.com/shaneosullivan/ReactNativeExampleBrowserExtension . The problem can be seen by checking out the code, running npm install then trying to build it.

I figured it out. It turns out that I needed to add ActionViewController.m to the compile sources of both targets for it to compile separately. Perhaps it's worth updating the instructions to say so?
