Building React Native for iOS fails: code signature not vaild for AppAuth

I am trying to integrate react-native-app-auth into my React Native app. It works on Android, but when trying to build the project on iOS I get the following:

dyld: Library not loaded: @rpath/AppAuth.framework/AppAuth
  Referenced from: /private/var/containers/Bundle/Application/38019FA7-8A4E-43F9-93BE-51A59E42308B/MapMobileWorkbench.app/MapMobileWorkbench

(lldb) 

After that pops up, continuing the run the app causes it to crash.

Both the .a library and the .framework for AppAuth are in the link list for the target I am building, but the color of the icon for the .framework file is more of a pale yellow versus the regular yellow of the rest of the .framework files linked. That is the only thing I have noticed that might mean something. I have tried deleting and reinstalling my pods a number of times without any luck there, either. And I have tried both the new and the legacy build systems. I am not sure what else to try.
