Library not linking with 0.41 versions of react-native - ios

Question

I'm having issues linking libraries to a react-native project even after attempting to link manually multiple different times. I've gone through a ton of "praised" tutorials with no success.
I'm not an expert in Objective-C/iOS-native, so to isolate the issue I decided to create a HelloWorld Library and a HelloWorld react-native project.
Using:
react-native v0.41.2
react-native-cli v2.0.1
react-native-create-library v1.0.4
xcode v8.2.1
I did the following:
react-native-create-library Lib.
react-native init RNLibTest.
"Successfully linking" (Tried both manually and react-native link ...)
Here is the code:
RNLib
// ./ios/RNLib.h
#import <React/RCTBridgeModule.h>
#interface RNLib : NSObject <RCTBridgeModule>
#end
// ./ios/RNLib.m
#import "RNLib.h"
#implementation RNLib
RCT_EXPORT_MODULE();
RCT_EXPORT_METHOD(helloWorld:(NSString *)world)
{
return [NSString stringWithFormat:#"hello %#", world];
}
#end
// ./index.js
import { NativeModules } from 'react-native';
const { RNLib } = NativeModules;
console.log(RNLib); // undefined
console.log(NativeModules); // Object: RNLib NOT included
export default RNLib;
HelloWorld / RNLibTest
// index.ios.js
import React, { Component } from 'react';
import { AppRegistry, Text, View } from 'react-native';
import RNLib from 'react-native-lib'; // I installed RNLib with npm and then "linked".
export default class RNLibTest extends Component {
componentDidMount() {
console.log(RNLib); // undefined
}
render() {
return (
<View>
<Text>Hello World</Text>
<Text>{
RNLib.helloWorld("world")
/* throws error "can't read property helloWorld of undefined" */
}</Text>
</View>
);
}
}
AppRegistry.registerComponent('RNLibTest', () => RNLibTest);
My questions:
If the code is not wrong, could it be the xcode project created by react-create-native-library somehow not working with newer versions of react-native?
Is anyone else having these issues? If so, what did you do to fix it?
If you haven't encountered this issue, are you using the latest version of react-native?
What version are you using of xcode, react-native-cli, etc...?
Did anyone have to downgrade to fix this issue?
UPDATE Feb/22/2017
There is a new release of react-native-create-library (v1.1.0) that supports v0.40+. I tried again and updated the code above, but I'm still seeing the same issue.
Here is a link to the GitHub issue. I also uploaded react-native-lib library and LibTest app to GitHub.

Answer 1

Not Sure Whether react-native-create-library support 0.41 RN But from the code i could say you need to import RCT*h files like <React/RCTBridgeModule.h>
Since this is single fine you can create a RNLib.h File in Xcode and check you would get compile time error
Thanks

I don't know what caused the issue but with react-native 0.42 out, I decided to try again.
Same code, same libraries, same everything BUT react-native 0.42, these were my results:
using react-native link => WORKED.
using manual installation => WORKED.
I'm not sure what happened in 0.41 but it is not happening in 0.42!
