How can i add Authorization header to a wkwebview. I checked https://developer.apple.com/documentation/foundation/nsurlrequest#1776617 which says Authorization header is a reserved http header and shouldn’t be set. I want to set it when requesting a url in wkwebview for authentication purpose?

In the Safari browser on mobile devices, the tags in an HTML element are styled with the system's default styles. I want the text inside the tags to be displayed without line breaks. However, in reality, the text wraps according to its length. May I ask if there are any methods to achieve this? (ps: CSS-related properties such as white-space: nowrap do not work.)

Hi, I would like to share a finding and ask for a solution, if possible. This may be a potential bug with PointerMoveEvent on Safari on an iPad with Pencil Pro. I tested onPointerMove and onTouchMove in a <canvas> element in a React web app for freehand drawing using Mouse on a PC. Finger touch on iPad Apple pencil pro on iPad Finger touch on iPhone I was able to draw smooth curves in all cases except when using onPointerMove with Apple pencil pro on iPad. The curve drawn in this case looked like it was created using several straight-line segments. It seems like the sampling rate for PointerMoveEvent is lower than that of TouchMoveEvent on Safari I am not sure how to solve this problem or if it is an issue with Safari's interpretation of PointerEvents. Any input is greatly appreciated. Edit: It seems like https://developer.apple.com/forums/thread/689375 is related.

We are currently implementing the payment flow, and for handling payment details — including card entry and validation — we are utilizing a WKWebView. The webview securely loads the payment provider’s page, ensuring sensitive information such as card numbers are entered and validated directly within the web context. I’d like to clarify that this change has not yet been released to Production. As part of a feature enhancement to our existing payment flow, we are transitioning to a new payment vendor, SnapPay. While trying to load the SnapPay URL embedded within an iFrame in our iOS app, I observed the following error in the Xcode console. While this error may be generic, I wanted to highlight it: 825a18 - [pageProxyID=7, webPageID=8, PID=67346] WebPageProxy::didFailLoadForFrame: frameID=24, isMainFrame=0, domain=NSURLErrorDomain, code=-999 Upon investigating, we compared the headers from our existing payment URL and SnapPay's URL, and found that SnapPay includes the following Content-Security-Policy (CSP) header: Content-Security-Policy: frame-ancestors ... "Content-Security-Policy" value="default-src 'self'; script-src 'self' https://hcaptcha.com https://.hcaptcha.com https://code.jquery.com https://www.gstatic.com https://code.jquery.com/jquery-3.3.1.min.js https://test.lightbox.cardx.com/v1/lightbox.min.js https://www.ssa.gov/accessibility/andi/ https://c.evidon.com 'unsafe-inline' 'unsafe-eval'; style-src 'self' https://hcaptcha.com https://.hcaptcha.com https://fonts.googleapis.com/css https://stage.snappayglobal.com/Resource/ https://www.ssa.gov/accessibility/andi/andi.css 'unsafe-inline'; img-src 'self' data: https:; font-src 'self' *.googleapis.com *.gstatic.com ; connect-src 'self' https://demo1.cditechnology.com https:; form-action https://hcaptcha.com https: 'self' *.ipg-online.com secure.bluepay.com https://test.api.lightbox.cardx.com https://3ds-acs.test.modirum.com/ https://demo1.cditechnology.com/; frame-ancestors https://snappaydirect-perf.fiserv.com 'self' file: https: http; frame-src .snappayglobal.com 'self' https://hcaptcha.com https://.hcaptcha.com https: https://www.google.com .ipg-online.com secure.bluepay.com https://.cardconnect.com https://test.api.lightbox.cardx.com/ https://test.lightbox.cardx.com https://paywithcardx.com/payment/auth.cgi securepayments.cardpointe.com *.cardpointe.com https://3ds-acs.test.modirum.com/ https://www.yokohamatire.com http://uat1-txt.ad.portal.texas.gov https://uat1-txt.ad.portal.texas.gov " After multiple working sessions with the SnapPay team, we were able to confirm that when they disable CSP or remove the frame-ancestors directive, the iFrame loads successfully within our app. However, SnapPay cannot change on their CSP. To enable the iFrame to load in the iOS app, we added the following line of code: webView.configuration.preferences.setValue(true, forKey: "allowFileAccessFromFileURLs"). This resolved the issue with loading the iFrame. Note: the file being loaded is a local .html file,. Before submitting this update to the App Store, I’d like to confirm whether this usage of allowFileAccessFromFileURLs is acceptable for App Store review. I wanted to confirm that with this change is there a security concern for WKWebview?

Hi everyone! We encountered an issue with universal links where the link failed to open the iOS application from Safari when triggered by an event listener. However, when we modified the code to open the link directly via a user click, the application launched as expected. Based on our testing, this issue seems to occur only when there is information for the application cached in Safari. Our previous flow that resulted in the broken universal link included: Data is loaded and a screen with a button to open the universal link is available for the user When the data is loaded it sets a state variable to true for DataLoaded The user clicks on the button to open the universal link When the user clicks the button to open the link it sets a variable to true for ButtonClicked When DataLoaded and ButtonClicked are true then the universal link is opened Our new flow that results in the successful universal link includes: Data is loaded and the user is hit with a loading screen until it is finished The user clicks on the button to open the universal link and the universal link is opened directly Does anyone have insights into why universal links must be triggered by direct user action, and in what scenarios this behavior is enforced?

Hi everyone, I'm facing an issue with accessing device orientation and motion events in Safari on my iPhone (iOS 18). Despite trying several guides and solutions, I cannot find the option to allow access to motion and orientation for websites in the browser settings. I’ve checked privacy settings, and the device is up to date. Can anyone guide me on how to enable this feature in Safari or share any workarounds? Thanks in advance!

Hi, I am developing the Click & Read web add-on for Chromium, Firefox and Safari. We use xcrun safari-web-extension-converter tool to generate the Safari add-on, with up-to-date MacBook MacOS, Xcode et Safari : Sequoia 15.3.2, Safari Version 18.3.1 (20620.2.4.11.6), XCode Version 16.0 (16A242d). We have updated our addon to Manifest v3, having the Background script as Server Worker "background": { "service_worker": "background.js", "type": "module" } self.addEventListener("activate", (event) => { console.info("Service Worker activated", event); event.waitUntil( self.registration.pushManager .subscribe({ userVisibleOnly: true, applicationServerKey: urlBase64ToUint8Array( process.env.VAPID_PUBLIC_KEY ), }) .then(async (subscription) => { console.info("[Service Worker] Extension is subscribed to push"); const { subscription: savedSubscription } = await getLocalStorageKeyData("subscription"); if (savedSubscription) fetchApi({ url: `${API_SERVER_URL}/subscription/remove/${savedSubscription.keys.auth}`, }); // Remove previous subscription from server on addon activate currentBrowser.storage.local.set({ subscription: subscription.toJSON(), }); // Save subscription in local storage currentBrowser.runtime.setUninstallURL( `${API_SERVER_URL}/subscription/remove/${ subscription.toJSON().keys.auth }` ); // Set uninstall URL to remove notification subscription on addon uninstall fetchApi({ url: `${API_SERVER_URL}/subscription`, reqInit: { body: JSON.stringify(subscription.toJSON()), method: "POST", headers: { "Content-Type": "application/json", }, }, }); }) .catch((error) => { console.error("Push subscribe error: ", error); }) // Subscribe to push notifications ); }); When trying to subscribe the addon instance to our Push server, we get this error : Push subscribe error: NotAllowedError: User denied push permission Our NodeJS backend is using the web-push librabry : https://github.com/web-push-libs/web-push) to save subscriptions and make notifications push. By looking for same errors on forums, the best hint I found is that it could be related to the testing is done on localhost (addon is built from XCode onto Safari, and Push server is running on localhost). Thanks for your help !

Hi everyone, My web application has two services: myapp.com and account.myapp.com. The first manages all app content, while the latter handles the authentication, with Sign In with Apple included. The tech stack is mainly composed of React, JS, and Express. We'd like to allow users to authenticate inside a dialog on some pages of myapp.com. To avoid replicating stuff from one service to another, we put an iframe inside the dialog to show the authentication standard page from account.myapp.com. Email and Facebook processes work fine, but we have the following issues with Sign in with Apple: On desktop, not Safari, a pop-up window opens when you click on the Apple button, and it works as expected. On desktop Safari, the pop-up window is blocked. We want the native Apple pop-up to show instead of a generic browser new window. On mobile, nothing happens on click Obviously, outside the iframe, everything works as expected. I can't seem to find anything related to an iframe constraint in the Sign in with Apple docs. Is this feasible?

Hello, I was going through the Apple Pay API documentation and noticed ambiguity on the exact process to complete merchant validation. One of the documentation mentions that the validation url will be Your server posts a request using mutual TLS (mTLS) by calling the Apple Pay server’s Payment Session endpoint. Endpoint (Global) POST https://apple-pay-gateway.apple.com/paymentservices/paymentSession Endpoint (China region) POST https://cn-apple-pay-gateway.apple.com/paymentservices/paymentSession Referencing the url: https://developer.apple.com/documentation/apple_pay_on_the_web/apple_pay_js_api/requesting_an_apple_pay_payment_session whereas the other references that the value should be used as provided by the onvalidatemerchant event object with the property validationURL. Refer: https://developer.apple.com/documentation/apple_pay_on_the_web/apple_pay_js_api/providing_merchant_validation Can someone confirm which is the correct approach to follow ?

We have a Safari extension that's been up on the App Store for about 18 months with no apparent issues. This week, however, while working on an update, we uninstalled the production version on our test machines and installed a developer version. When we had some issues, we tried to go back to the production version downloaded from the App Store, but we get an pop saying "Unable to download App." In the log, the most obviously relevant error is 'Operation not permitted'. This occurs on several machines and different logins on those machines in both norma and safe modes. However, on another machine that never had one installed, we could still install the app from the app store, so I suspect there is something left behind that needs to be removed, but I don't know what. FWIW, I see the download directory getting created under /Applications, but it is promptly removed when the failure popup appears. Any suggestions?

Anybody succeeded sending a Web Push Message using the new Declarative approach introduced with Safari Version 18.4 (20621.1.14.11.3)? I will help as well if someone can point me to a solution debugging the entire system using Xcode and Minibrowser? Currently I can't get the MiniBrowser connected to the WebPush Daemon.

When our Safari Web Extension makes a api request from its background script (registered via "scripts" in manifest.json, e.g., "background": { "scripts": ["js/background.bundle.js"] }) to our authenticated API endpoint (https://api-domain/user), the Cookie header is not included in the request. This occurs only when the extension is running within a non-default Safari User Profile. This causes our API to treat the user as unauthenticated. The exact same extension code, manifest, and API call work correctly (Cookie header is present and user is authenticated) when the extension is running in the Default Safari User Profile.

The order nor -webkit-order properties of a child element of a flex parent dosen't work in Safari 18.3. Works correctly in FireFox and Chrome.

I have a Safari extension that plays audio via the javascript AudioContext API. It was working fine under iOS 17 and is now broken under iOS 18. It does not play audio at all. I've tried in both the iOS 18 public beta and the iOS 18.1 developer beta. It is broken in both of them. I've also created Feedback item FB15170620 which has a url attached to a page I created which demonstrates the issue.

I have a business scenario where I want to guide users to Safari and open a Safari extension. How can I open Safari from my app and navigate to a specific webpage?

Hi Apple developers, I am very new to XCode and Swift, I am planning to build an app for iOS from a web. I tried to use WKWebView to handle the web , I managed to redirect some of the links to Safari, however some button/links didn't trigger .linkActivated function and encounter the error as "Your browser preventing this app to open “URL”. If I copy the URL to Safari is able to open, I trying to research on web but can't find any related solution for my case. Here is the code in my app: import UIKit import WebKit import SafariServices class ViewController: UIViewController, WKNavigationDelegate { var webView: WKWebView! override func viewDidLoad() { super.viewDidLoad() // Initialize WKWebView let webConfiguration = WKWebViewConfiguration() //enable javascript webConfiguration.preferences.javaScriptEnabled = true webView = WKWebView(frame: self.view.frame, configuration: webConfiguration) webView.navigationDelegate = self self.view.addSubview(webView) // Load a web page as webview if let url = URL(string: "https://myurl") { let request = URLRequest(url: url) webView.load(request) } //console log webView.evaluateJavaScript("console.log('Button clicked!')") { result, error in if let error = error { print("Error executing JavaScript: \(error.localizedDescription)") } else { print("JavaScript result: \(String(describing: result))") } } } func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) { if let url = navigationAction.request.url, navigationAction.navigationType == .linkActivated { // Check if URL is external and open it in Safari if UIApplication.shared.canOpenURL(url) { UIApplication.shared.open(url, options: [:], completionHandler: nil) decisionHandler(.cancel) // Prevent loading the link in the WebView } else { decisionHandler(.allow) // Allow loading if URL cannot be opened in Safari } } else { decisionHandler(.allow) // Allow the WebView to load the URL normally } } }

Hey team, I've integrated custom WkWebsiteDatastore to manage profiling for different sessions. upon testing the WkWebsiteDataStore as its mentioned to be persistent But The storage can be accessed via identifier, But the session data in storage is absent, such as cookies caches all are cleared when app is relaunched is it the default behavior to be expected or there is some property missing causing the session data to be removed from storage.

I build websites and my current build has seven videos on the first page built with the html 'video' tag. The page renders on all browsers and Android and on Safari on my mac but on my iPhone safari they appear black and then play correctly when clicked. This has changed since the last update.
