They can communicate directly within your app, improving both user experience and convenience. This feature allows for real-time discussions and swift decision-making, potentially saving valuable time and resources.

This level of accessibility is particularly important for services like telehealth, online tutoring, or remote customer support, providing users with valuable services at their fingertips

What are the options to add Video Conferencing SDK and API in your iOS app?

Building Natively with WebRTC:

For developers seeking greater control and customization, building the video conferencing experience natively with WebRTC is an option. This approach offers full customization to seamlessly integrate features and user interface with your app, complete control over security and privacy measures, and freedom from vendor lock-in. However, it comes with increased development complexity due to the intricacies of WebRTC protocols, longer development time for building and maintaining the infrastructure, and ongoing maintenance for updates and security.

Third-Party SDKs:

This method offers a faster and more cost-effective solution by leveraging pre-built libraries and functionalities provided by dedicated video conferencing platforms. Key advantages include faster development due to existing APIs and features, reduced complexity by avoiding intricate infrastructure development, and ongoing scalability through the provider's maintenance. However, potential drawbacks include vendor lock-in limiting customization, potential subscription or usage-based costs, and limited control over security and privacy.

That’s where Dyte stands out, you enjoy the customization and control of a WebRTC with the speed and reliability of a managed SDK. You can embed enterprise-class scalability, HD call quality, customization, and secure video interactions all in under five minutes with Dyte.

Before Getting Started​

Make sure you've read the Getting Started with Dyte topic and completed the steps in the Integrate Dyte section. You must complete the following steps:

• Create a Dyte Developer Account
• Create a Dyte Meeting
• Add Participants to the meeting. This API returns the authentication token that is required to initialize your frontend SDKs.

Step 1: Install the SDK​

CocoaPods​

1. Add the following line to your Podfile.

pod 'DyteUiKit' , '0.6.0'

2. Install the client SDK as a CocoaPods dependency.

pod install

Swift Package Manager​

Add DyteUiKit SDK through Swift Package Manager in Xcode. Use https://github.com/dyte-in/ios-uikit-framework.git as the package source.

3. Add the necessary fonts and permission entries in the info.plist file. You can customize the strings shown in the permission pop-ups to match your audience preferences.

<key>NSBluetoothPeripheralUsageDescription</key>
<string>We will use your Bluetooth to access your Bluetooth headphones.</string>
<key>NSBluetoothAlwaysUsageDescription</key>
<string>We will use your Bluetooth to access your Bluetooth headphones.</string>
<key>NSCameraUsageDescription</key>
<string>For people to see you during meetings, we need access to your camera.</string>
<key>NSMicrophoneUsageDescription</key>
<string>For people to hear you during meetings, we need access to your microphone.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>For people to share, we need access to your photos.</string>
<key>UIBackgroundModes</key>
    <array>
        <string>audio</string>
        <string>voip</string>
        <string>fetch</string>
        <string>remote-notification</string>
    </array>

The UIBackgroundModes key in the Info.plist file declares the types of background tasks an iOS app can perform, allowing it to run and complete specific tasks in the background. Use of background modes must be justified and adhere to Apple's App Store Review Guidelines to avoid app rejection for misuse or unnecessary background running.

Step 2: Configure a Dyte meeting and Launch UI​

To set the initialization properties in the DyteUiKit class, simply initialize DyteMeetingInfoV2 and provide the participant's authToken. You can get the authToken via the Add Participant API.

Try this in viewDidAppear()

import DyteUiKit
import DyteiOSCore

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
    }
    var dyteUikit: DyteUiKit!

   override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        dyteUikit = DyteUiKit(meetingInfoV2: DyteMeetingInfoV2(authToken: authToken, enableAudio: true, enableVideo: true, baseUrl: Constants.BASE_URL))
        let controller = dyteUikit.startMeeting {
            [weak self] in
            guard let self = self else {return}
            self.dismiss(animated: true)
        }
        controller.modalPresentationStyle = .fullScreen
        self.present(controller, animated: true)
    }
}

Here's a visual representation of all the configuration options described.
