WKWebView

For iOS usage scenario, using the WKWebView is one of the recommended ways.

After creating the transaction and getting the transaction link, the following implementation is recommended:

• In your common flow (which IDPay is inserted) you will open the WKWebView with the link generated through the API;
• Customize this opening in any way that is ideal for your application;
• Monitor if the URL has changed (to redirectUrl) and then close the WKWebView;

The following code shows how to open a WKWebView:

import UIKit
import WebKit
import SafariServices

var webView: WKWebView!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
    self.view.backgroundColor = .white
}

@IBAction func open(_ sender: Any) {
    createWKWebViewFull()
}

func createWKWebViewFull() {
    webView = WKWebView(frame: self.view.bounds, configuration: getWKWebViewConfiguration())
    webView.navigationDelegate = self
    view.addSubview(webView)
    self.loadUrl()
}

func loadUrl() {
    if let url = URL(string:"<URL_TO_LOAD>") {
        webView.load(URLRequest(url: url))
        webView.allowsBackForwardNavigationGestures = true
    }
}

private func getWKWebViewConfiguration() -> WKWebViewConfiguration {
    let config = WKWebViewConfiguration()
    config.allowsInlineMediaPlayback = true
    config.mediaTypesRequiringUserActionForPlayback = []

    return config
}

The following code shows how to control when to close the WKWebView:

func webView(_ webView: WKWebView, didCommit navigation: WKNavigation!) {
    if let currentURL = webView.url {
        print("URL changed to: \(currentURL.absoluteString)")
        if currentURL.absoluteString == "<URL_TO_OBSERVER>" {
            closeWebView()
        }
    }
}

@objc func closeWebView() {
    DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
        self.webView.removeFromSuperview()
    }
}

Follows an example of how it should look in the APP:
