Video on Safari iOS - UI/UX of Shadow Content User Agent
Hi, when I display an HTML page with a on Safari iOS, I get a nice UI. Great! At the first look I see a video frame with an arrow-in-a-circle button in the middle. Very nice. I click on the arrow and I get a fullscreen view while the video begins to play. I watch the video then I pause it then I click on the top-left x button. So I go back to my html page and the video is perfectly there as it was before. But, there is an annoying new detail. The video frame is really dark, it still presents all the controls and a "different" arrow button to play it again. In other words that nice video-frame, that nice picture, is not longer visible on the page. That nice page with nice pictures has now an almost-black rectangle. Too bad. Sure I can click on the video (outside the controls) then the controls and the black overlaying frame disappear. I can see that nice picture again. Finally. Well, but the arrow-in-a-circle button to play the video disappeared. Now the user cannot longer understand that's a video to play. It looks just like any other pictures to admire statically. Is any way to get the previous first look of the video? The one clear, with the current frame and the arrow-in-a-circle look?

Smart App Banner has changed background color
We have a Smart App Banner (including App Clip) on our website and have noticed today that the banner's background color has changed. It no longer has the default white background and blue button color, instead it has a background color that matches our page's background, and even the color of the button has changed. What's interesting is that we have not triggered this change at all. The colors seemingly changed by themselves. Looking at the Apple Documentation, no customization options are mentioned. Searching the web, the theme-color meta tag is mentioned in relation to this, however we haven't even included that tag on our page. What is triggering this color change then and how can we influence it?

Simulator 18.4 Webview CORS issues
I have a very specific issue that happens only on iOS Simulator version 18.4. It does NOT happen when I run my app on a real iOS 18.4 device through Testflight. My app displays a WebView (courtesy of Capacitor, url scheme capacitor://). Inside that Webview I'm using Firebase JS API (11.2.0) and calling signInWithEmailAndPassword, which works well in all other contexts, i.e. browser, Android webview, iOS webview in all other Simulator versions, and on real devices. Only when running in Simulator 18.4, I get a failed network request: cannot parse response Fetch API cannot load https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?... due to access control checks. Failed to load resource: cannot parse reponse error: FirebaseError: (auth/network-request-failed) Everything is working correctly for both: Capacitor app webview installed on a real 18.4 device with Testflight Safari (non-webview) in the 18.4 Simulator The issue is severe for us, because we are unable to develop our app and test it in the simulator on 18.4 Simulator before pushing it through Testflight internal release. Request headers on the failed request (no response status or headers available). Request Accept: / Content-Type: application/json Origin: capacitor://localhost Sec-Fetch-Dest: empty Sec-Fetch-Mode: cors Sec-Fetch-Site: cross-site User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 18_4 like Mac OS X) - AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148 X-Client-Version: Mobile/JsCore/11.2.0/FirebaseCore-web X-Firebase-Client: (...)

HELP!Apple Pay Web application cannot pay due to the bottom rotation issue
I built a web application using the Apple Pay on the Web Interactive Demo with the Payment Request API, but encountered a few issues: The initiated web Apple Pay interface shows a spinning circle at the bottom and cannot proceed with payment(Bottom display:正在处理). What could be causing this? How to set up sandbox testing for payments? How to asynchronously and synchronously retrieve payment results (backend code to fetch payment results)? The demo only shows frontend code using await response.complete("success"); for retrieving payment results my demo URL: https://shop.wowseer.com/rsolomakhin/pr/applepay/

WebKit's `decidePolicy` breaking change in iOS 18.5 + Xcode 16.4
It seems that in iOS 18.5+ built with Xcode 16.4+, there has been a breaking change since 18.4 with 16.3 within WebKit and how the navigationAction.sourceFrame property is initialized when implementing the decidePolicy delegate method. The flow goes: Implement a WKNavigationActionDelegate with decidePolicy Call WKWebView.loadHTMLString("some-string", baseURL: nil) Upon loading the HTML content, read the value of navigationAction.sourceFrame within the decidePolicy method of the WKNavigationActionDelegate On iOS 18.4 (and below) with Xcode 16.3 (and below); navigationAction.sourceFrame is <uninitialized> On iOS 18.5+ with Xcode 16.4+: navigationAction.sourceFrame is already initialized and is equal to navigationAction.targetFrame It appears that this change was made between minor versions of Xcode and is unexpected behavior of a minor version. Not only was this not called out in the release notes for Xcode 16.4 and iOS 18.5, but it's technically also a breaking change to the WebKit API. Can we get insight on why this change was made and what Apple's policy is on breaking changes between minor versions of Xcode/iOS?

[iOS 26 Beta] event.target.value is always empty — only from specific script domains
Hey everyone, After installing iOS 26 beta, I started noticing unexpected behavior in our input event handlers. Specifically, when users type into an field, event.target.value is always an empty string — but only when the JS file is loaded from a specific domain (e.g., t1.daumcdn.net). The exact same code works perfectly when hosted on other domains like t2.daumcdn.net or search1.daumcdn.net. 👉 I created a demo here: 🔗 https://codepen.io/bzasklcu-the-sans/pen/rNXogxL The scripts loaded from each domain are 100% identical (apart from the top-level selector). Before iOS 26 beta, this worked fine. I suspect this is related to ITP or some new cross-origin behavior in Safari, but I’d love to know if anyone else is running into this — or if someone knows a workaround. Thanks!

Issue with External Browser on Sign In (Privy SDK limitation)
Hello Apple App Review Team, We are using Privy to enable sign in with Farcaster in our app. Privy is a 3rd party authentication SDK, and it currently opens the authentication URL using the system browser. Unfortunately, this behavior is handled internally by Privy and we do not have access or control to override it in order to present the sign-in flow in-app using SFSafariViewController. We understand the importance of maintaining a seamless and secure user experience, and we fully support the use of SFSafariViewController or ASWebAuthenticationSession. However, since Privy does not expose an option to change this behavior at the moment, we are limited by their current implementation. We have reached out to the Privy team requesting a change or improvement that would allow us to use SFSafariViewController instead of the external browser. In the meantime, we would appreciate your guidance on how to proceed, or whether an exception could be granted due to this 3rd party SDK limitation. Thank you for your understanding and support.

iOS Safari - Input element is unresponsive when modifying DOM via a touch event (touchstart, touchmove, touchend, etc)
This is a really strange issue on iOS Safari. Under certain conditions a basic input element will not be focusable or show the on screen keyboard. I can reproduce the issue with a very simple HTML file by dynamically adding an anchor element with an href during a touch event. If you add a different element or an anchor without an href, there is no issue. Similarly, if you apply the same listener to a click event there is no issue. Reproducible in iOS Simulator 17.2 and 18.1 This HTML/JS showcases the problem: <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <title>InputIssue</title> <meta name="viewport" content="width=device-width, initial-scale=1" /> </head> <body> <div id="parent"> <input type="text" name="test" /> <div id="child"></div> </div> <script> document.addEventListener("touchstart", () => { const child = document.getElementById("child"); if (!child) return; while (child.firstChild) { child.removeChild(child.firstChild); } const link = document.createElement("a"); link.href = "https://test.com"; link.textContent = "test"; child.appendChild(link); }); </script> </body> </html>

Why does NSURLSession with Multipath entitlement seamlessly switch to cellular when on a hardware Wi-Fi with no internet, but WKWebView does not?
正文:大家好, 当设备连接到没有互联网的 Wi-Fi SSID(例如,硬件设备的 AP)时,我看到 NSURLSession(multipathServiceType = NSURLSessionMultipathServiceTypeInteractive)和 WKWebView 之间的行为存在令人费解的差异。我正确启用了多路径授权,在这种情况下: NSURLSession 请求会自动回退到蜂窝网络并成功(无需用户干预,快速切换)。 WKWebView 加载失败或停滞:Web 内容未出现,即使系统网络路径得到满足并确认了真正的 Internet 可访问性,Web 视图似乎也没有使用蜂窝路径。 环境: iOS 版本:(例如 iOS 18.4) 设备:(例如 iPhone 15 Pro) 多路径权利:在应用程序中启用,使用 NSURLSessionMultipathServiceTypeInteractive 连接的 SSID:硬件设备 Wi-Fi,无需外部互联网 预期回退:一旦 Wi-Fi 没有互联网,就会自动到蜂窝网络,如 NSURLSession 所观察到的那样 我做了什么/观察到什么: 使用多路径的 NSURLSession 按预期工作:NSURLSessionConfiguration *cfg = [NSURLSessionConfiguration defaultSessionConfiguration];cfg.multipathServiceType = NSURLSessionMultipathServiceTypeInteractive;NSURLSession *session = [NSURLSession sessionWithConfiguration:cfg];NSURLRequest *req = [NSURLRequest requestWithURL:[NSURL URLWithString:@“https://www.apple.com/library/test/success.html”]];NSURLSessionDataTask *task = [session dataTaskWithRequest:req completionHandler:^(NSData *data, NSURLResponse *resp, NSError *err) { NSLog(@“NSURLSession result: %@, error: %@”, resp, err); }];[任务简历];连接到设备 Wi-Fi(无外部 Internet)时,会话会悄悄地切换到手机网络并成功完成。 相同情况下WKWebView加载失败:[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@“https://www.apple.com/library/test/success.html”]]];Web 视图要么显示负载失败,要么只是挂起,即使较低级别的监视报告网络路径已满足并且真正的 Internet 连接可用。 网络路径监控逻辑: 我使用 C API nw_path_monitor来监视nw_path_status_satisfied。 一旦观察到满意,我就会使用nw_connection(例如,连接 tohttps://www.apple.com/library/test/success.html)执行真正的连接检查,以验证真实的互联网流量是否可以通过蜂窝网络流动。 该检查通过,确认回退到手机网络,但 WKWebView 仍不会加载内容。同时,相同条件下的 NSURLSession 请求会立即成功。 示例日志记录跟踪:[+] nw_path_status_satisfied=1, hasWiFi=1, hasCellular=1 [+] Internet 连接测试:准备就绪(通过 nw_connection) [-] WKWebView 加载失败/停滞 [+] NSURLSession 请求成功完成 问题: 为什么当 Wi-Fi 没有 Internet 时,具有多路径服务类型的 NSURLSession 无缝使用蜂窝网络,但 WKWebView 不表现出相同的回退行为?WKWebView 是否不以相同的方式接受系统的多路径回退?在这种情况下,它是否使用不同的网络堆栈或忽略多路径授权? 是否有一种受支持的方法可以强制 WKWebView 像 NSURLSession 一样运行? 例如,我是否可以通过启用多路径的 NSURLSession 桥接内容,并通过自定义方案将其注入 WKWebView? 是否有任何 WKWebView 配置标志、首选项或策略启用相同的自动接口切换? 与原始 NSURLSession 相比,WKWebView 处理网络接换、路径满意度或多路径的方式是否存在已知限制或记录在案的差异? 我排除/尝试过的: 已验证多路径授权是否包含且处于活动状态。 确认的网络路径“满足”,并且在调用 [webView loadRequest:] 之前,真正的 Internet 可访问性成功。 将 WKWebView 加载延迟到连接验证之后。 观察到 NSURLSession 请求在相同的连接条件下成功。 任何对内部差异、推荐的解决方法或 Apple 推荐的模式的见解,以使 Web 内容在“没有互联网的 Wi-Fi”+ 自动回退到蜂窝场景中变得健壮,我们将不胜感激。 谢谢!

Can't publish my app due to Mini apps
Hello Community, My application was rejected by Apple App Review, citing Guideline 4.7 and "non-embedded," which I believe is incorrect. All transactions are signed and sent directly through the app with explicit user permission. Additionally, there's an issue with min apps where users can access the functionality via a browser to interact with the service. This feature has been part of my old application and hasn't changed in the new update. It’s the same functionality as used by popular wallets like Metamask Uniswap Coinbase Which also employ web3 technology. Over the past two weeks, I've tried to communicate with Apple's support team but have been ignored or received only generic rejection emails. This has left me frustrated and concerned about the time and resources I’ve invested in developing and supporting this app. Could you please help me find a solution? Your assistance would be greatly appreciated!

Inquiry Regarding Unsubscribe Flow for Recurring Payment Processing
We would like to confirm the unsubscribe flow related to recurring payment processing. When a user unsubscribes, does your system send any notification to us? If no notification is provided, we will not be able to detect the unsubscribe event and will continue to send recurring payment requests to the gateway periodically. Would this cause any issues? We would appreciate it if you could share the specific unsubscribe flow with us. Thank you in advance for your support.

Is Picture in Picture supported for WebRTC / WebView video on iOS (outside app)?
Hello, I am implementing video calling on iOS and need to support Picture in Picture (PiP) behavior similar to FaceTime or WhatsApp. What works Audio continues correctly in background CallKit UI works as expected Video works correctly while the app is in the foreground What I’m trying to achieve When the user presses the Home button or switches apps, I want to show a system Picture in Picture window (floating video outside the app). Current setup Video is rendered via WebRTC The video is displayed inside a WKWebView (HTML / JavaScript) PiP works only while the app is foregrounded When the app backgrounds, the video disappears (only audio remains) Questions Does iOS support system Picture in Picture for: WebRTC video WKWebView / HTML video 2 Is AVPictureInPictureController limited only to: AVPlayerLayer AVSampleBufferDisplayLayer 3 If PiP requires native rendering: Is it mandatory to render WebRTC frames natively using AVSampleBufferDisplayLayer? Is PiP explicitly unsupported for WebView / HTML video? 📌 Clarification Apps like FaceTime and WhatsApp are able to show PiP outside the app. I want to understand whether this behavior is achievable only with native video pipelines, or if WebView-based video is fundamentally restricted by iOS. Any official clarification or documentation reference would be appreciated. Thank you.

iOS Safari Rendering Issue: Sticky Header Sometimes Fails to Update After DOM Changes
I’m encountering an issue on iOS when rendering a list using React. Each list item uses the array index as the React key and consists of two parts: a header section that uses position: sticky for dynamic sticking behavior, and a body section whose height is automatically adjusted based on its content. When the list data is updated, I sometimes observe that the sticky header content does not update visually in time, even though the underlying data and DOM have changed. // demo.jsx import React, { useState } from 'react'; import { Button } from '@iftide/mobile'; import './style2.less'; // import data1 from './data1.json'; // import data2 from './data2.json'; const prefixCls = 'im-detaillist'; const data1 = [ { sectionTitle: '2025年05月' }, { sectionTitle: '2025年04月' }, { sectionTitle: '2025年03月' } ]; const data2 = [ { sectionTitle: '2023年08月' }, { sectionTitle: '2023年07月' }, { sectionTitle: '2023年06月' }, { sectionTitle: '2023年05月' } ]; export default function App() { const [list, setList] = useState(data1); const [toggle, setToggle] = useState(true); return ( <div> <Button title="更新2" onClick={() => { setToggle(!toggle); setList(data2); }} /> <div className={`${prefixCls}-container2`} style={{ height: `700px` }}> {list.map((section: any, sectionIdx: number) => { return ( <div className={`${prefixCls}`} key={String(sectionIdx)} // id={section.sectionTitle} > <div className={`${prefixCls}-section-title`} role="text"> {section.sectionTitle} </div> <div style={{ background: 'green', height: `${Math.ceil(400 * Math.random()) + 50}px` }} > 省略 </div> </div> ); })} </div> </div> ); } .@{prefixCls}-section-title { position: sticky; position: -webkit-sticky; will-change: transform; top: 0; z-index: 1; padding-left: 11px; width: 100%; height: 30px; font-size: var(--font-size-s); font-weight: 400; line-height: 30px; color: #000000; background-color: #F4F5F7; letter-spacing: 0; }

In Safari's JavaScript geolocation, is altitude based on MSL or WGS84 ellipsoid?
Hello all, I'm trying to retrieve geolocation data on the web, but I'm having trouble with the altitude value, which seems to differ from what I get on Android. When using navigator.geolocation.getCurrentPosition in Safari, is the altitude value based on mean sea level, or is it ellipsoidal altitude based on the WGS84 ellipsoid? altitude (WebKit JS): https://developer.apple.com/documentation/webkitjs/coordinates/1631861-altitude altitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/altitude ellipsoidalAltitude (Core Location): https://developer.apple.com/documentation/corelocation/cllocation/ellipsoidalaltitude If anyone has any insight into this topic I would greatly appreciate it!

Apple Pay on Web scan-to-pay, the service is unavailable
I integrated Apple Pay on the web following the documentation, and verified that the payment works successfully in the sandbox environment using Safari on iOS and Mac. Later, I launched the Apple Pay payment code on a third-party web page that supports Apple Pay, and scanned the code with the camera of an eligible iOS device. The camera then displayed the Apple Pay button; after tapping it, a brief pop-up message saying ‘Service Unavailable’ appeared, and then it closed automatically. How can I troubleshoot and resolve this issue?

Videos keep refetched with loop
Hello there, For a video like this <video src="blob:safari-web-extension://***" autoplay="" loop="" style="position: absolute; top: 0px; left: 0px; width: 100%; height: 100%; object-fit: cover; z-index: -1;"></video>, no matter if its local or remote, blob or mp4 files, is constantly being reloaded (refetched? revalidated?) if the loop tag is added. I can confirm there is actual constant traffic from the server based on my server logs. I am running iOS/macOS 26.
