I am following up on Thread (https://developer.apple.com/forums/thread/733233). Currently, SFSafariExtensionManager.getStateOfSafariExtension only returns if an extension is enabled, but not if "Allow in Private Browsing" is toggled on. Is there an API in macOS 26 and Safari 19 that allows a native Safari App Extension to detect this specific permission?

Cross posting from Spatial Computing, apologies if this is not the appropriate forum. The purpose is to create a simple web-based gallery of spatial photos and videos using static html files. I have successfully displayed spatial photos using the img tag and IMG.heic files. I can tap and hold the image to bring up the contextual menu and from there select View Spatial Photo. Is there any way to add a control to the image, like a link or overlay on the image itself, that a user can simply tap to show the image in 3D? And how to host a (small!) video file on a web page without going through a CDN/streaming service? Sample html would be much appreciated.

Hello, After upgrading to macOS 26.2, I’ve noticed a significant performance regression when calling evaluateJavaScript in an iOS App running on Mac (WKWebView, Swift project). Observed behavior On macOS 26.2, the callback of evaluateJavaScript takes around 3 seconds to return. This happens not only for: evaluateJavaScript("navigator.userAgent") but also for simple or even empty scripts, for example: evaluateJavaScript("") On previous macOS versions, the same calls typically returned in ~200 ms. Additional testing I created a new, empty Objective-C project with a WKWebView and tested the same evaluateJavaScript calls. In the Objective-C project, the callback still returns in ~200 ms, even on macOS 26.2. Question Is this a known issue or regression related to: iOS Apps on Mac, Swift + WKWebView, or behavioral changes in evaluateJavaScript on macOS 26.2? Any information about known issues, internal changes, or recommended workarounds would be greatly appreciated. Thank you. Test Code Swift class ViewController: UIViewController { private var tmpWebView: WKWebView? override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. setupUserAgent() } func setupUserAgent() { let t1 = CACurrentMediaTime() tmpWebView = WKWebView(frame: .zero) tmpWebView?.isInspectable = true tmpWebView?.evaluateJavaScript("navigator.userAgent") { [weak self] result, error in let t2 = CACurrentMediaTime() print("[getUserAgent] \(t2 - t1)s") self?.tmpWebView = nil } } } Test Code Objective-C - (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions { NSTimeInterval startTime = [[NSDate date] timeIntervalSince1970]; WKWebView *webView = [[WKWebView alloc] init]; dispatch_async(dispatch_get_main_queue(), ^{ [webView evaluateJavaScript:@"navigator.userAgent" completionHandler:^(id result, NSError *error) { NSTimeInterval endTime = [[NSDate date] timeIntervalSince1970]; NSLog(@"[getUserAgent]: %.2f s", (endTime - startTime)); }]; }); }

Description: In our app, we have login page which displayed in WKWebView. In that page, there is an Remember my Device cookie option which user can select, so next time it OTP page will not be displayed. Problem Statement: Recently we found that some issue happened with this cookie. Especially, when users upgraded their OS versions to 18.6 or 26.1 or 26.2. Need to understand, any changes related to Cookie part in latest OS Versions?

When trying to login using apple account it shows me this error "Your request could not be completed because of an error. Please try again later." although in the inspector everything looks fine (200)

I coded two demo websites as follows (both written in NextJS): Website 1: I coded an interval counter that increments every 1 second. Website 2: I used the MediaRecorder API (described in the WebKit documentation: https://webkit.org/blog/11353/mediarecorder-api/). In the ondataavailable function, I periodically send a blob (once every 1 second) to my server. In the backend, I coded a POST API to upload this blob. I noticed that with website 1, the interval doesn't work when I run Safari in the background, even on iOS and iPadOS. However, website 2 works, meaning it still calls my API normally (I tried running Safari in the background for about 1-2 hours and it worked). So, does this mean Apple allows native APIs like MediaRecorder and its callbacks to run in the background?

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; }

Please kindly improve the Safari browser side bar implementation further along with what The Browser Company has done with their Arc browser. Arc is about to retire soon too and they're willing to sell their SwiftUI code perhaps too for a decent pile of dollars, not the Jony Ive piles at least it should not. The toggle for side bar is nice and works perfect though!

Bit of an odd one here, just keen to understand if it’s just me or a more generic issue. For all other apps, I can drag the icon from the dock to place into stage manager left, centre or right. However when I try to do the same with Safari (and only Safari), it just doesn’t work at all. I can repeat this 100%, has been an issue with 26.0, 26.1 and now 26.2. Can confirm this isn’t a problem on my 11” M4 iPad pro running same O/S. Here is a video showing the issue (YouTube) https://youtu.be/0WBGBZVHsfs

I'm in the process of supporting Apple Pay through a 2nd payment gateway for some users, so I need to support two separate Apple Pay relationships. Both require their own apple-developer-merchantid-domain-association. I don't see how I can have both files for the one domain. Is this possible? Is there a workaround other than just replacing the old file with the new one and hoping that doesn't disrupt anything. That seems to be the approach taken by others (https://developer.apple.com/forums/thread/695538) but it is too high risk for me without any confirmation from Apple that this is ok. I'd also like to avoid having to setup a 2nd domain for these customers, since the current domain is already quite embedded in their operations.

Hello, We are experiencing a behavior change with WKWebView related to upgradeKnownHostsToHTTPS. Current application, we explicitly disable automatic HTTPS upgrades: let config = WKWebViewConfiguration() config.upgradeKnownHostsToHTTPS = false Observed behavior iOS 17.5 (built with Xcode 15.3) http:// image URLs are not automatically upgraded to https://, and the behavior works as expected. iOS 18.5 / 18.6.x (built with Xcode 16.4) http:// image URLs appear to be automatically upgraded to https:// by WebKit, even when upgradeKnownHostsToHTTPS is explicitly set to false. This behavior occurs for subresource requests such as <img src="http://..."> inside a WKWebView. Question Has the behavior of upgradeKnownHostsToHTTPS changed in iOS 18 / Xcode 16? Is this property now ignored for certain types of subresource requests (e.g. images), or overridden by new WebKit security policies such as mixed-content HTTPS upgrades? Any clarification or official guidance would be greatly appreciated!.

Problem Safari requires tabindex="0" for keyboard access to scrollable containers. Chrome (v130+) and Firefox (v4+) handle this automatically. Current Behavior Chrome/Firefox: Scrollable div with overflow: auto → automatically keyboard-accessible (Tab to focus, Arrow keys to scroll) Safari: Same element → NOT keyboard-accessible unless: Add tabindex="0", OR Container has focusable children Workaround <div style="overflow-y: auto; height: 300px;" tabindex="0"> <!-- content --> </div> Issue: Adds unnecessary tab stops on Chrome/Firefox where not needed. Request Will Safari support auto-focus for scrollable containers? (matching Chrome/Firefox) If not planned: Any official Apple guide for cross-browser scrollable accessibility? Timeline? If on roadmap, estimated Safari version? Can I subscribe for updates?

WKWebView has a new property "isBlockedByScreenTime" since iOS 26. But I do not yet understand when exactly this property could be used. When I setup content-based restrictions in the ScreenTime settings then WKWebView reports an error 105 via "webView:didFailProvisionalNavigation:" delegate. The isBlockedByScreenTime property still returns false in this case. If ScreenTime has a time-based limit, the App would not run at all. Under which circumstances would the property "isBlockedByScreenTime" return the value true? When exactly and for what can this property be actually used? The "problem" is that I want to find if a web page is blocked and can not be loaded, why this is the case. By simply trial and error I found out that WKWebView returns error codes 104 and 105 for blocked web sites because of content filters and Screen Time restrictions, however these error codes are not documented at all (at least I've not found any documentation or documentation for these error codes and also some other codes like 100, 102, 204 etc), so I'm not really sure if I handle all cases correctly. I hoped that isBlockedByScreenTime would at least tell me one reason for blocked pages. If there are documents which explain these error codes (100 and above), where I can find these?

Also, it doesn’t seem to have any negative consequences other than the console spam? But then, the navigation is being cancelled anyway, so maybe it’s trapping and just happens to have the effect of not loading the request? Anyway, I guess I can’t upload zips. But it’s pretty easy to reproduce. Just assign a WKWebView a navigationDelegate with an implementation like: func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping @MainActor (WKNavigationActionPolicy) -> Void) { decisionHandler(.cancel) } and then have it .load() anything. Have I been doing this wrong and 26 exposes it? Or is this a bug in 26? If the latter, any downstream consequences I should be looking out for? macOS 15.7.1 (24G231) Xcode 26.1.1 (17B100) iOS 26.1 (23B86)

My iOS app uses a WKWebView with a WKUIDelegate method (webView:createWebViewWithConfiguration:forNavigationAction:windowFeatures:) to handle popup windows. This works for most cases, but during OAuth flows on certain sites (e.g., canva.com), the popup WKWebView attempts to send results back to the main WKWebView using JavaScript like window.opener.postMessage(...). However, window.opener is always null in the popup, preventing the message from being posted and blocking login completion.I've researched this and found suggestions that it's by design, as WKWebView instances are isolated for security reasons. Has anyone encountered this and found a reliable workaround (e.g., bridging communication between the main and popup WKWebViews without relying on window.opener)?

Hello WebKit Team, I’m writing to ask if iOS provides a native way to intercept AJAX (XMLHttpRequest or fetch) calls inside WKWebView. On Android, this is handled via: shouldInterceptRequest(WebView view, WebResourceRequest request) but iOS currently seems to have no equivalent. We’ve tried: WKURLSchemeHandler → works only for custom schemes URLProtocol with WKProcessPool → unreliable for AJAX in WebView JavaScript injection → partial and unofficial Could you please clarify: Is there a recommended native approach to intercept AJAX requests? If not supported, is it planned for future releases? Any official workaround or guidance? This is critical for debugging, analytics, and compliance in hybrid apps.

webkitEnterFullScreen API is supported on iOS for video element, but not for a div element. Also as a fullscreen demo website shown, Safari on macOS supports div element but not on iOS. Is there any plan to add the support in iOS? If not is there any way to fullscreen a div element or make it run as fullscreen on Safari iOS?

在 iOS 平台使用 WKWebView 通过file://协议加载本地 HTML 文件时，存储在localStorage中的数据会在 App 后台切换、进程重启后偶尔丢失；但相同代码在安卓 / 鸿蒙平台无此问题。 现在的文档 仅明确了「默认数据存储（defaultDataStore）可将网站数据持久化到磁盘，非持久化存储（nonPersistent）仅存内存」的基础规则； 未提及「file://协议内容即使使用默认持久化存储，也会被归为临时内存存储」这一关键场景限制； 仅在WKURLSchemeHandler关联说明中隐含「自定义 URL 协议可处理 WebKit 原生不支持的 URL 方案」，但未直接关联file://的存储问题。 我找不到如何处理这个问题的官方文档，仅仅有其他的博客说需要增加http/https加载就没有这个问题。 请提供给我官方文档或者官方回复 关于出现这种file:/加载html出现问题的处理办法

Hello, can't find a better Forum and after all this is Apple Support here? Seems starting with iOS 26.2 RC2 our Newsletter is no longer rendered 'responsive' so with unuseable small font. Anybody any suggestion? Or maybe @apple fix the bug? Where would I even start to debug this? I don't have any iphone at hand so i only got screenshots from users. Our where can i contact the actual apple support? correct: invalid:
