Since iPadOS 18.x WKWebView seems to have a bug within its Fullscreen API (which can be enabled via WKPreferences.isElementFullscreenEnabled). This bug has the effect that websites trying to make an element (for example a video player) fullscreen fail to do so. This does not always happen, most of the time the fullscreen mode does work fine, but sometimes (far too often to be ignored) it does not. If an instance of WKWebView shows this issue, it can not be "fixed" by reloading the page or loading other pages, this issue exists in this instance forever. My App is a web browser App so I can create and remove WKWebView instance easily (by opening or closing Tabs). And there are times where I never see this bug, and times where ever other tab shows this bug. It's totally unreliable. The App does not show any issues at all when running under iPadOS 17 or older. The issue is only present under iPadOS 18.x. After some testing I've found out that when the bug has affected an instance of WKWebView, the JavaScript call element.requestFullscreen() will work if the element is a video element, but does no longer work if it is another element (like a DIV). If an instance of WKWebView is not affected by this bug, element.requestFullscreen() will work for all HTML elements. Does anyone has experienced this bug as well? And maybe found a workaround? Or maybe found a pattern which helps to find out what exactly is triggering this bug?

I'm building a share extension for my app when I noticed something weird. When I open a mobile URL (URLs with "m." like m.randomsite.org) on iOS using a browser (I'm using Safari & Chrome) and then try to share it, what will be share is the URL without the "m." (i.e. randomsite.org) This messes up with my app since I'm not getting the real URL that I'm viewing using the browser. I don't think it has something to do with my app since even selecting "Copy" when sharing will result in the altered URL too. So far this is happening on both iOS 17 and 18. Does someone know whether this is a bug from iOS or not? I don't think this is a Safari bug since I noticed the same thing on Chrome as well

After upgrading to Safari version 18, we encountered an issue with my extension’s background script not being able to access cookies. Previously, in Safari versions 17 and below, the extension worked as expected. Now, when the extension tries to retrieve cookies using browser.cookies.getAll(), it returns an empty list. However, if we open the extension’s developer tools, the cookies are visible and accessible. It seems that Safari only provides cookie data after the developer tools have been opened. However, after relaunching Safari and launching the extension without opening the developer tools, browser.cookies.getAll() still returns an empty list. Has anyone else experienced this? STEPS TO REPRODUCE Download this minimal app : https://www.icloud.com/iclouddrive/0bajlhnuQaG6T5NsFKXEB0U9Q#test%5Fcookies Compile test_mv2 extension (in test_cookies.getAll.zip). Launch test_mv2.app and activate extension. Click on the extension's button (browserAction). Open the developer tools. Observe an empty list of cookies. Click on the extension's button (browserAction). Cookies are retrieved as expected.

We have an iOS app (which runs on macOS via "Designed for iPad") which renders web content on WKWebView. Our users can select text (standard OS way of click & drag cursor across text) and then perform actions on those discrete pieces of text. On macOS 15.1, our users can only expand a text selection, they cannot contract the text selection by dragging the cursor to the left. This reduces the usability of our app on macOS 15.1. This is not an issue on macOS 14. Environment: MacBook Pro (2021 16” M1 Max), macOS 15.1 Submitted Feedback FB15726254.

This is my first time to post on this forum. If there are something we didn't notice, please tell me. Thanks. Background We're using canvas to provide a web component to marketing. https://demo.mescius.jp/spreadjs/BenchmarkSample/ Problem Recently we have met an issue from customer. He is using iPad 10th to access the web component but when he tries to scroll it and it's very slow on iPad 10th. His iPad OS version is 17.7 and this issue also can be reproduced on our iPad 10th with iPad OS 18.0.1. But if we use iPad 9th with iPad OS 17.7 and 18.0.1, things are fine and there isn't any performance issue. We developer took some time investigating and found it's because of iPad 10th's safari takes longer time to paint each frame. On iPad 9th, it needs nearly 10ms to paint each frame. But on iPad 10, it needs nearly 70ms to paint each frame. Also we can provide simple code for you to check the different. We tried to simulate the repaint when user is scrolling. You can see on iPad 9th, it will be 2~3ms but on iPad 10th, it will be more than 10ms for each frame. test-ipad10.html It has been happening on iPad 10th only with iPad OS 17.6/17.7/18.0. This will be a big problem for us because it means on the iPad 10th (the latest iPad, non Pro or Air), it can't be used. Question Is there anyone knowing similar issue with this one? And do you know how to solve it on iPad 10?

I have a Safari extension which allows the user to load their own homepage upon opening a new tab. The extension works by retrieving the homepage URL from UserDefaults and then redirecting to it using window.location.replace. In iOS 18, if the homepage is unable to be loaded due to, for example the user having no internet connection, Safari will go into an rapid loading loop, which eventually stops after a while. This is unlike iOS 17, where trying to reproduce the same scenario will end up with a Safari error page, which should be the expected behaviour. In short, instead of Safari going into an infinite loading loop, it should display a Safari error page like iOS 17 does. As this issue is only happening on iOS 18, I am almost certain it's an iOS bug and would appreciate if this can be fixed as soon as possible. I have created a Feedback Assistant report with ID FB15853821, which contains a sysdiagnose file from my iPhone 16 Pro, as well as two videos, one from my iPhone 16 Pro with iOS 18.2 beta 3 and the other video showing a comparison between iOS 18 and 17. Both videos first show the extension functioning correctly with an active internet connection, but when I disable my internet, the iOS 18 Safari goes into an infinite loop. Here are the steps to reproduce the issue: Download the Homepage for Safari app from the App Store: https://apps.apple.com/gb/app/homepage-for-safari/id6481118559 Enter any valid homepage URL, such as https://apple.com and tap Save Go to Settings -> Apps -> Safari -> Extensions -> Homepage and enable the extension Make sure Open New Tabs is set to “Homepage” Turn off both WiFi and cellular data and attempt to open a new tab in Safari Please note that this also happens with iOS 18.2 beta 4.

I wanted to create a public contact card so when my clients click a button on my website it traverses them through the iMessage API and instantly adds a contact card with photo and name as a background task. If there is implications my next question was going to be if there is a possible way to create a public contact card where for example I could redirect a client to iMessage and when starting a new conversation if they type in a name it pops up instead of needing to utilize a phone number? I am trying to explain my thought process as much as possible but I have been typing for hours. In simple terms is there a possibility to create a public contact card that can be accessed or texted by anyone who types in a name into new conversation bar?

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 } } }

After the iOS 18.2 update, I can no longer see the some website as I could see it on the desktop. ( for example Jeostok . Com)I have tried this in many browsers. For example, I get the same result in browsers such as Safari Chrome Firefox opera and edge. The home page is not displayed properly. It was displaying properly before the update and now it is not displaying properly. This website is my website. I frankly do not know how to solve this problem, if anyone knows, I am waiting for your help.

Hello everyone, I'm working on an app that uses WKWebView. My app uses a custom menu and we disable the default menu by overriding with: WKWebAction.canPerformAction() However, with the new iOS 18.2 release, I am no longer able to override the "Copy Link with Highlight" option that pops up when highlighting a selection as can be seen from the screenshot: Has anyone found a work around/bypass for this? Environment iOS Version: iOS 18.2 Device: iPhone 13 Pro App platform: iOS Xcode version: 16.1 MacOS: 14.5

Hi everyone, I’m working on a Safari browser extension and recently encountered a major issue after transferring the extension from one Apple Developer account to another, then releasing an update under the new account. Following this update, user engagement has dropped off dramatically. My understanding—based on my own investigations, which may be limited—is that this problem arises because Safari is treating the extension as entirely new due to the change in the developer account. Here’s what I’ve pieced together so far: • Safari appears to rely on an Extensions.plist file, which uniquely identifies each installed extension by a combination of its bundle identifier and the associated developer account ID. • The Extensions.plist file also stores the state of granted permissions for each extension. Because our extension now has a new developer account ID, Safari no longer seems to recognize it as the same extension that users had previously approved. • As a result, previously granted permissions appear to have been lost, and users must manually re-enable the extension—leading to a significant drop in engagement and revenue. I’m hoping someone can clarify the following: Is there a known migration path to transfer an extension between developer accounts without causing users to lose their previously granted permissions? Are there best practices, or workarounds, for maintaining continuity when the bundle identifier and/or developer account ID changes? Are there any tools for re-linking permissions after a bundle identifier or developer account ID change? Has anyone worked through a similar scenario and found a solution or guidance from Apple Developer Support or the Safari team? I’ll also be reaching out to Apple Developer Support directly, but any insights from those who’ve dealt with this scenario would be greatly appreciated. Thank you!

Hello there I have a nested USDZ file I had created a long time ago with some make-up products. Its behaviour was always the same in the past: nested usdz files allow you to control each object "nested" separately. So I used this as a way to allow people to play around with a "set of objects". Today I went to try it and since I'm on ios 18 it shows an "assets tab" on the bottom that allows me to see all the assets inside the tab but doesn't allow me to see or anchor them at all! What changes do I need to do in order for this to work and where can I check documentation on these new behaviours for USDZ files? And what will this allow for in the future? Thank you in advance

Hi, I have implement a WebRtc cameras server: IP camera -> ffmpeg -> WebRtc -> browser The video codec used is H264. I test it on a MAC mini using safari browser (latest version) The Rtc peer connection is correctly connect but the video is not display. looking for the event on the video control, I got this: loadstart progress suspend On the MAC, I have also a chrome browser installed and trying the same, it works fine, I got this: loadstart progress loadmetadata loadeddata canplay canplaythrough playing the video control on the html page is declared like this: Does anyone have an idea why the video stay suspend or have a clue or tips to make it work? Thanks in advance

I'm making a Safari extension for learning languages. I need speech synthesis for any language the user chooses to learn. I initially tried to make this work within JavaScript, but Safari 18 doesn't reliably list voices for all languages on the web SpeechSynthesis API as described here: https://stackoverflow.com/questions/79179072/how-do-you-use-a-japanese-voice-with-speechsynthesis-in-safari-ios-18 As a workaround, I've had to use AVSpeechSynthesizer in SafariWebExtensionHandler (NSExtensionRequestHandling implementation for the extension). This works in the simulator but not on a real device. I've found this note from Apple in a StackOverflow reply: "Safari extensions are very short-lived, hence not fit for audio playback or speech synthesis. Not being able to validate an app extension in Xcode with a manually-added plist entry for background audio is the designed behavior. The general recommendation is to synthesize speech using JavaScript in conjunction with the Web Speech API." Unfortunately, the suggestion to use the Web Speech API is unsuitable as I just explained. Is there a way to set up a background process in the host app that can do speech synthesis? The app extension would need a way to communicate with this process, and start it if it's not running. Is that possible?

We have a web application that uses high resolution images to validate the authenticity of products. For this purpose we want to use the best camera to make the high resolution camera, on iPhone Pro devices this camera is the ultra-wide angle camera. The issue we have is how to confidently select that camera from the list returned by navigator.mediaDevices.enumerateDevices. We can't use the device ID as it change every time (and for every user), we could use the camera name but the string is translate to the device language which is very problematic. We could also just select a specific item in the list but we are not sure that the order is preserved and it makes it hard to deal with other iPhone models that don't have that ultra wide angle camera. Selecting a specific camera looks like an essential feature not only for us. What is the best option, we are looking for something that is future proof and easily scalable.

It's being a very long time that I discovery that in some web pages, that use function requestAnimationFrame will cause a lot of cpu, but very little in Chrome. I have already submitted this bug nearly two years ago without printout requestAnimationFrame, no one replied. I submitted again and mention requestAnimationFrame recently, hope there will be some response. If anyone interested in this issue and know some tech in javascript please help. You can enter https://www.baidu.com/ and click one of the topic in all the 百度热搜 which have 弹幕滚动(using requestAnimationFrame, and cause a lot of cpu usage) on right.

When I download specific files (not limited to a single website), even if I find that the downloaded file size matches the original file size and the downloaded file size no longer changes, Safari still does not stop the download thread, but continues to wait indefinitely. This results in the Safari not terminating the download thread even after the file download is completed, making it impossible to complete the download; The file has not been landed and cannot be obtained. This prevents me from downloading some files. Please fix this problem. In addition, I found that in iOS 18.2, during the process of downloading files on Safari, the synchronization and backup flags appear in the upper right corner of the notification bar. I am not sure if this is an unexpected behavior, but the flag still lingers for a long time after manually canceling the download thread. (the download thread is waiting indefinitely) Feedback Number: [FB16124044]

Hello, I’m encountering a problem with WebSocket connections in Safari on iOS 18.1 and later when initiated from an iframe. The same implementation works perfectly in other browsers like Chrome but fails in Safari. In Safari, the WebSocket connection fails with error message "WebSocket connection to 'wss://MY_CONNECTION_URL' failed: The internet connection appears to be offline." Has anyone else faced this? Is this a known limitation or bug in Safari? Any workarounds or solutions would be greatly appreciated. Thank you!

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!
