iOS

This document provides instructions to create a WebView into an iOS project.

iOS Info.plist

Add these lines to the Info.plist file in you iOS module:

<key>NSCameraUsageDescription</key>
<string>Camera Permission</string>
<key>NSMotionUsageDescription</key>
<string>Motion Permission</string>

iOS WebView (Swift)

In order for web Onboarding integrations that use WKWebView for iOS to function properly, it is necessary to customize the configuration to allow media playback without request user's action and to reproduce the media inline.

For iOS, WKWebView is the preferred WebView. The example below is a basic illustration.

AppDelegate

@main
class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        window = UIWindow(frame: UIScreen.main.bounds)
        window?.rootViewController = WebViewController()
        window?.makeKeyAndVisible()
        return true
    }
}

SceneDelegate

import UIKit

class SceneDelegate: UIResponder, UIWindowSceneDelegate {
    var window: UIWindow?

    func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        guard let windowScene = scene as? UIWindowScene else { return }

        window = UIWindow(windowScene: windowScene)
        window?.rootViewController = WebViewController()
        window?.makeKeyAndVisible()
    }
}

WebViewController

@preconcurrency import WebKit
import AVFoundation

class WebViewController: UIViewController, WKNavigationDelegate, WKUIDelegate {
    var webView: WKWebView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        setupViews()
        setupConstraints()
    }

    func setupViews() {
        let webConfiguration = WKWebViewConfiguration()
        webConfiguration.allowsInlineMediaPlayback = true
        webConfiguration.defaultWebpagePreferences.allowsContentJavaScript = true
        webConfiguration.mediaTypesRequiringUserActionForPlayback = []

        webView = WKWebView(frame: .zero, configuration: webConfiguration)
        webView.navigationDelegate = self
        webView.uiDelegate = self
        view.addSubview(webView)

        let request = URLRequest(url: URL(string: "https://cadastro.io/:token")!)
        webView.load(request)
        
        AVCaptureDevice.requestAccess(for: .video) { granted in
            if granted {
                // Access granted
            } else {
                // Access denied
            }
        }
    }

    func setupConstraints() {
        webView.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            webView.topAnchor.constraint(equalTo: view.topAnchor),
            webView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
            webView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
            webView.bottomAnchor.constraint(equalTo: view.bottomAnchor)
        ])
    }
}
