Problem Statement:-

How to start a Zoom meeting within any iOS native application using Zoom SDK in Swift.

Zoom is a HaaS (Hardware as a Service) product that offers world-class communication experience with video telephony and online chat services. Zoom is widely popular for teleconferencing, telecommuting, distance education, and social relations. Moreover, Zoom achieved exponential growth during this unprecedented coronavirus pandemic, making the whole world shut down for a few months.

Description of the Issue:-

I was working on an iOS application that allows patients to fix online appointments with doctors. The application was embedded entirely in WKWebView. The client requirement was to integrate Zoom into the application. However, on clicking the Zoom start meeting button, the button’s action would trigger in JavaScript, which had no effect on starting a zoom meeting in Safari.

The Solution Offered:-

I integrated Zoom SDK into our project successfully by following a few steps that are listed below. 

1. Register Your App:

To register your app, visit the Zoom App Marketplace and click on the Develop option in the dropdown on the top-right corner and select Build App. A page with various app types will be displayed. Select SDK as the app type and click on Create.

2. Generate App Credentials:

To allow your app to integrate, the Zoom platform generates a set of unique credentials used to generate the tokens needed to authorize each request. The unique set of app credentials generated for you by the Zoom marketplace includes an SDK Key and SDK Secret. Having retrieved your SDK Key and SDK Secret, your app is all set to utilize any Zoom SDKs.

3. Development environment for Zoom SDK in iOS platform :

iOS IDE: Xcode

iOS system version: min support = iOS 8, max support = iOS 13

iOS device and simulator: Zoom SDK & SDK demo will work only in the following environment.

Real iOS Device:

Type: iPhone, iPad, iPod 

OS: iOS 8 to iOS 13


Type: iPhone, iPad

OS: iOS 8 to iOS 13

4. Download the Zoom SDK :

There are two versions of SDK – one will work on both device and emulator, and the other one will only work on the real device. Please visit Zoom Github repo for further information:

Please visit to get the Zoom SDK versions.

Let us install the latest zoom version v5.0.24433.0616.

The code in the “Source Code (zip)” is the device-only version. It only works on a real device. Please use this version if you would like to upload it to the Apple App Store.

5. Integrate Zoom SDK to the project :

Zoom iOS SDK requires the following frameworks:



Drag and drop the above two frameworks into the project:

In your project setting, navigate to the General section: Zoom iOS SDK is a dynamic library, which requires importing into the following – Frameworks, Libraries, and Embedded Content.


Then navigate to Build Phases > Copy Bundle Resources, and add MobileRTCResources.bundle:


After importing the framework and bundle, now you can start using Zoom services inside your own applications.

6. Required permissions:-

Zoom video conferencing requires the following permissions:

  • Microphone
  • Camera
  • Bluetooth
  • Photo Library

You need to specify these permissions in your project settings Info.plist.

  • Open your Info.plist, right-click at the empty space, and select Add Row.
  • A new row will be added, for the key, select “Privacy – Camera Usage Description,” input any descriptions for your permission request in the value column.
  • Add other rows for “Microphone, Bluetooth, and Photo Library.”



<string>We will use your Bluetooth to access your Bluetooth headphones.</string>


<string>For people to see you during meetings, we need access to your camera.</string>


<string>For people to hear you during meetings, we need access to your microphone.</string>


<string>For people to share, we need access to your photos</string>


Go to Appdelegate.swift file and use the below-mentioned code:

import UIKit

import MobileRTC

import MobileCoreServices


class AppDelegate: UIResponder, UIApplicationDelegate, MobileRTCAuthDelegate {

var window: UIWindow?

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {


        return true



func onMobileRTCAuthReturn(_ returnValue: MobileRTCAuthError) {


        if (returnValue != MobileRTCAuthError_Success) {

            let msg = “SDK authentication failed, error code: \(returnValue)”





 func authenticateZoomSDK() {

        let mainSDK = MobileRTCSDKInitContext.init()

        mainSDK.domain = “”

        mainSDK.enableLog = true


        let authService = MobileRTC.shared().getAuthService()

        let clientKey = CLIENT_KEY

        let clientSecret = CLIENT_SECRET   

        if let authService = authService {

            authService.delegate = self

            authService.clientKey = clientKey

            authService.clientSecret = clientSecret






Now move to your ViewController, where you wanted to implement Zoom video calling and use the below-mentioned code.

import UIKit

import MobileRTC

class ViewController: UIViewController  {    

    //Zoom related variables

    let kSDKUserName: String = ZOOM_USER_NAME

    let kSDKUserID: String = ZOOM_ID

    var zak: String?

    var kSDKMeetNumber: String?

    let appShare: Bool = false


    //MARK:– Override methods

    override func viewDidLoad() {




    //MARK:– Start Zoom meeting

    func startZoomMeeting() {

        if(self.kSDKMeetNumber == “”) {

            print(“Please enter a meeting number”)


        } else {

            //let auth = MobileRTC.shared().isRTCAuthorized()

            let getservice = MobileRTC.shared().getMeetingService()

            if let service = getservice {

                service.delegate = self

                //service.customizeMeetingTitle(“Sample meeting title”)

                let user = MobileRTCMeetingStartParam4WithoutLoginUser.init()

                user.userType = MobileRTCUserType_APIUser

                user.meetingNumber = kSDKMeetNumber

                user.userName = kSDKUserName

                user.userID = kSDKUserID

                user.isAppShare = appShare

                user.zak = zak 

                let param = user

                let ret: MobileRTCMeetError = service.startMeeting(with: param)

                print(“onStartMeeting: \(ret))





extension WebViewControl: MobileRTCMeetingServiceDelegate {

    func onMeetingStateChange(_ state: MobileRTCMeetingState) {

        print(” Meeting state: \(state))




If you follow all the steps mentioned above correctly, you will see the zoom meeting screen in your Zoom SDK implemented ViewController.
