PaperProvider theme doesn't work for release build on IOS

For debug build it show my custom theme but for release it shows purple color instead of mine.

Version:

    "react": "16.8.1",
    "react-native": "0.61.3",
    "react-native-paper": "3.1.1",

Code:

import {DefaultTheme, Provider as PaperProvider} from 'react-native-paper';

const theme = {
  ...DefaultTheme,
  roundness: 7,
  dark: true,
  mode: 'adaptive',
  colors: {
    ...DefaultTheme.colors,
    primary: Colors.mantis,
    accent: Colors.nero,
  },
};

const logger = createLogger();
const persistedReducer = persistReducer(persistConfig, reducers);
const store = createStore(persistedReducer, {}, applyMiddleware(ReduxThunk, logger));
const persistor = persistStore(store);


const App = () => (
  <StoreProvider store={store}>
    <PersistGate persistor={persistor}>
      <PaperProvider theme={theme}>
        <App />
      </PaperProvider>
    </PersistGate>
  </StoreProvider>
);

@kevinsoellner try resetting metro cache: react-native start --reset-cache or expo start -c if using expo

Has this been fixed? I’m getting the same error when I build for release via Xcode:

Invariant Violation: Native module cannot be null.

This error is located at:
    in l
    in c
    in RCTView
    in Portal.Host
    in n
    in RCTView
    in n
    in RCTView
    in RCTView
    in h

I just updated to the latest npm version and tried pod install again. Still getting the same error message even after resetting cache.

EDIT

I figured out my problem. I just assumed since it was talking about Portal.Host, it was related to react-native-paper, especially since someone else had a similar problem. Turns out that I forgot to add a native module manually to my project since I switched computers (library was an ad library, so I just need to download that from their repo and add it to Xcode). Once I commented out my NativeModules code, release started working again. It’s because I added a flag to my code if (__DEV__) { return }.
