React-native-navigation: _reactNative.Navigation.startSingleScreenApp

[khenry10]

Issue Description

Xcode settings got wiped and some iOS files possibly lost through a git issue. Now the app won't start up (errors below). I re-done the whole library linking process and re-traced the steps but the app won't start.

Errors:

• red error simulator screen that says: _reactNative.Navigation.startSingleScreenApp is not a function
• the terminal window I ran "run-ios" fails and has this error:
  Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_RNNCustomViewController", referenced from: objc-class-ref in AppDelegate.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

https://wix.github.io/react-native-navigation/#/docs/Installing?id=requirements say to edit .h and .m, is there a specific example of what AppDelegate.h should look like?

Steps to Reproduce / Code Snippets / Screenshots

• npm run start
• run-ios --simulator="iPhoneX"

App.js:
import { Navigation } from 'react-native-navigation';

import AuthScreen from './src/screens/Auth/Auth';
import SequencesList from './src/screens/SequencesList/SequencesList';

Navigation.registerComponent("my-app.AuthScreen", () => AuthScreen);
Navigation.registerComponent("my-app.App", () => App);
Navigation.registerComponent("my-app.SequencesList", () => SequencesList);

Navigation.startSingleScreenApp({
screen: {
screen: "my-app.SequencesList",
title: "Sequences"
}
});
