I'm a newbie in react-native. I'm adding one feature in react-native to an existing swift application. I presented the RCTRootview from my native view controller. From there when user clicks on back button I have to go to Homepage which is written in swift. How do I communicate from react-native to native application code. Can someone please help me with this scenerio. I stuck at this point from last 2 days. Thanks in advance.

    Hey @darkheartfelt Did you see that date when he answered from the link you shared? I answered this first. Then how come this became duplicate? The link you shared should be the duplicate of this? – Sivajee Battina Aug 18 '18 at 06:14

Yes. I found out the answer for this. It is all possible with RCTBridgeModule. This piece of code illustrate how to do that.

#import "CalendarManager.h"
#import <React/RCTLog.h>

@implementation CalendarManager

RCT_EXPORT_MODULE();

RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location)
{
  RCTLogInfo(@"Pretending to create an event %@ at %@", name, location);
}

Now, from your JavaScript file you can call the method like this:

import {NativeModules} from 'react-native';
var CalendarManager = NativeModules.CalendarManager;
CalendarManager.addEvent('Birthday Party', '4 Privet Drive, Surrey');

Please follow the below official link about the concept and how to do it.
