Go to Xcode > Your App, create new file name VideosdkRPK.swift

IOS Screen Share IOS Screen Share

After click on Create button, it will prompt you to create bridging header.

IOS Screen Share

After creating bridging header file, create Objective-c file name VideosdkRPK

IOS Screen Share IOS Screen Share

  • For VideosdkRPK.swift file, copy the content from VideosdkRPK.swift.

  • For Appname-Bridging-Header file, just add #import "React/RCTEventEmitter.h" line.

  • For VideosdkRPK.m file, copy the content from VideosdkRPK.m.

Step 2 : Integrate Native Module on React native side

  • Create file with name VideosdkRPK.js and copy the code from VideosdkRPK.js.

  • Add below lines for handling enable and disable screen share event.

import React, { useEffect } from "react";
import VideosdkRPK from "../VideosdkRPK";
import { TouchableOpacity, Text } from "react-native";

const { enableScreenShare, disableScreenShare } = useMeeting({});

useEffect(() => {
VideosdkRPK.addListener("onScreenShare", (event) => {
if (event === "START_BROADCAST") {
} else if (event === "STOP_BROADCAST") {

return () => {
}, []);

return (
onPress={() => {
// Calling startBroadcast from iOS Native Module
