When CHIPS was introduced in 18.4 it worked well, however on 18.5 it does not appear to work. There do not appear to be release notes about this in 18.5, so can someone provide definitive if this is a defect that will be fixed, or have they already been deprecated?

Hello, In iOS 26 beta, we are seeing an unexpected behavior when using SwiftUI WebView (or a custom WKWebView via UIViewRepresentable). When an alert is presented above the WebView, the WebView immediately reloads to its initial page. The alert itself also disappears instantly, making it impossible for the user to interact with it. This issue occurs both with the new SwiftUI WebView / WebPage API and with a wrapped WKWebView. The problem was not present in previous iOS versions (iOS 17/18). Steps to reproduce: Create a SwiftUI view with a WebView (pointing to any URL). Add a toolbar button that toggles a SwiftUI alert. Run the app on iOS 26 beta. Tap the button to trigger the alert. Expected behavior: The WebView should remain as-is, and the alert should stay visible until the user dismisses it. Actual behavior: As soon as the alert appears, the WebView reloads and resets to the initial page. The alert disappears immediately. Minimal Example: struct ContentView: View { @State private var showAlert = false var body: some View { NavigationStack { WebView(URL(string: "https://apple.com")!) .toolbar { ToolbarItem(placement: .topBarTrailing) { Button("Close") { showAlert = true } } } .alert("Confirm close?", isPresented: $showAlert) { Button("Cancel", role: .cancel) {} Button("Close", role: .destructive) {} } } } } I'm using Xcode Version 26.0 beta 7 Thanks for your help.

I recently noticed that putting the app on background for some time, then switching back to it again causes the WKWebView to reload the current page, same with just hitting f5 on it. How do we disable this behavior?

The title says it all, and I've filed FB FB22353950 that includes an Xcode 26.4 Screen Saver test project, QT movie demonstrating the error, and a PDF with complete steps to build and test. I'm asking here just to learn if this sounds familiar. The SS built on 26.4 fails in 26.4, works fine on 26.3.1. I'll supply the test files if there's interest. Thanks.

Problem As the title says, Safari lost all my tabs once I updated to macOS 15.4. I do of course have "Safari opens with: All windows from last session" set. This has been my default for many years. Past Mitigation In the past I had a script that I could use to backup ~/Library/Safari that would save all my bookmarks and tabs. Unfortunately they made this method of backup non-function sometime around when tab groups were introduced. Suggestion Fortunately my tab groups are still intact. But this sort of problem doesn't give me a lot of confidence. I haven't had something like this happen in a while, but when it does happen, it's quite frustrating. Apple really needs to recognize that this sort of thing can and will happen and they should make it easier for users to manually save/restore their tabs. Problem with forums To add insult to injury, as I was typing this message in the forum, I decided to select "Edit Bookmarks"... which proceeded to replace the current window with my bookmarks, thereby losing my post! It did this without warning of page content changes (which I get from most other websites). I felt somewhat relieved that the forum had recognized a previous draft and offered for me to continue. However, when I selected it, it brought me back to an old post... that was actually posted! smh

When using iOS 26.2 (23C55) Safari, the following can occur. The current tab (A) opens a new tab (B) via window.open(url, target, windowFeatures). The user clicks the "back" button to close tab B, and returns to tab A. Tab A attempts to open tab B again at a later point, using the same "target" as before, and fails (no window object is returned by window.open). This bug only occurs when the target is the same as the previously closed tab (which was closed via the back button). If a new target is specified, the new tab opens as expected. This bug is also limited to the back button. If the user manually closes tab B, then it can be re-opened by tab A using window.open using the same target as before.

"The Referer header allows a server to identify referring pages that people are visiting from or where requested resources are being used. " This header is never forwarded to server when the user is browsing the website in a WebView. This is properly maintained by other browsers but not in-app. How do I include it?

I am new to PHP. I have developed my own web site with a lot of javascript in simple HTML files. I want to do some extensions with PHP but I can't make a simple web page function. I am sure something simple is wrong. Help! Here is the test web page I made: hello.html <html>  <head>   <title>Hello World</title>  </head>  <body>   <?php echo 'Hello World!'; ?>  </body> </html> Pointing Safari at hello.html gives me a new tab with the correct title, but no "Hello World" in the page itself. Here is the output of php --version: WARNING: PHP is not recommended PHP is included in macOS for compatibility with legacy software. Future versions of macOS will not include PHP.

Hello all, As you may know, the company ProofPoint is an Apple partner, and is engaged (I think) to reduce misuse of icloud emails. We have two servers solely set up for our web-app, which is a specialised forum for apartment owners. The new servers were established about the same time, with the same provider, with clean new IP addresses - and as mentioned above, are only used for this web-app. During a testing phase a YEAR ago, we became aware that our in-house icloud emails weren't receiving notifications via the app, and further investigations revealed that the cause was that ProofPoint had placed a block on that server's IP. We immediately, via their website form initiated a Support Ticket, which, the site indicated was lodged, BUT we have never received any response to that Ticket, nor have we received any response to four subsequent Tickets we initiated - nothing. In over a year!! Yesterday, we contacted Apple support, but the devices area of support is the main section and they said it wasn't an issue they could assist with. Some relevant matters: SPF: DKIM: DMARC: are, I believe all configured correctly (and Gmail gives a PASS to all of them). The IP is not blacklisted by any list we are aware of. Our other server's IP isn't blocked by ProofPoint. So, literally at wits end, I'm reaching out to the developer subscribers here to see if they have any suggestions for us. We currently are unable to accept any new subscriber that is using an icloud email address, and that's an absurd situation to be in. Surely we don't have to go to the trouble and inconvenience of obtaining a new IP because of this!!! But when we can't get ANY response to the Support Tickets, it's really hard. Thanks

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.

We are currently supporting an Apple Pay-enabled card program as an issuer/issuer processor and have successfully completed In-App Push Provisioning integration within our iOS application. The in-app flow is fully operational, including issuer-side cryptographic exchange and Mastercard MDES network tokenization. We are now looking to extend this integration to support Apple Pay Web Push Provisioning, allowing cardholders to add eligible cards to Apple Wallet directly from our web application. We would appreciate guidance on: -The process for enrolling in Apple Business Register (if required) -Enabling Web Push Provisioning for an issuer profile Required entitlements or provisioning certificates Any additional onboarding steps specific to issuer-level Web provisioning We understand that Web Push Provisioning requires issuer-level enablement beyond standard Apple Pay on the Web, and we would like clarification on the correct path to activate this capability. Thank you in advance for your guidance.

When using passkeys stored in iCloud Keychain (Passwords app) via Passkey Autofill in browsers other than Safari, the userVerification parameter is ignored and user verification (UV) is not performed. As a result, relying party servers that require userVerification = required fail validation because the UV flag is not set, causing passkey authentication to fail. This issue occurs when the following setting is disabled: Settings → Face ID & Passcode → Use Face ID For → Password AutoFill The issue is reproducible only with the following combination: Non-Safari browsers (e.g. Chrome) Passkeys stored in iCloud Keychain (Passwords app) Passkey Autofill The issue does not occur in the following cases: Safari with passkeys stored in any credential manager Non-Safari browsers using credential managers other than iCloud Keychain Steps to Reproduce: Go to Settings → General → Autofill & Passwords, and enable the Passwords app under “Autofill From”. Go to Settings → Face ID & Passcode → Use Face ID For, and disable “Password AutoFill”. Open Chrome and navigate to https://webauthn.io Enter a username and tap “Register” to create a passkey using the Passwords app (iCloud Keychain). On webauthn.io, go to Advanced Settings → Authentication Settings, and set “User Verification” to “Required”. Reload the page, tap the input field, and perform Passkey Autofill. User Verification is not triggered, and “Authentication failed” is displayed on webauthn.io. === This issue has already been reported via Feedback Assistant as FB21756948. I am posting here to confirm whether this behavior is working as intended or represents a bug, and to make other developers aware of the current behavior.

Our iOS app uses React Native Webview (based on top of WKWebView) to display content. This webview stays in memory throughtout the app's lifecycle. We are observing a high number of webview content process terminations - around 15% of our sessions. (https://developer.apple.com/documentation/webkit/wknavigationdelegate/webviewwebcontentprocessdidterminate(_:)) What could be the reasons for it? Is there a way to know for sure? Is the 15% of sessions number something that other apps also experience, or should this be lower? Thanks!

In iOS 26.4 beta, I noticed that when loading pages using WKWebView and using WebSocket to establish IP type addresses, the connection duration was several seconds and sometimes even failed to connect (normally, the connection duration should be in milliseconds). However, when establishing WebSocket connections using domain names, the connections were normal. Additionally, I discovered a special scenario: When directly establishing WebSocket connections using IP type addresses, it remained in the "connect" state. At the same time, based on Wireshark packet capture, it was found that no TCP connection was sent at this time. However, if two connections with the same address were established simultaneously, those two connections could successfully connect. This bug has seriously affected the use of my application service. Is there a chance that this version will solve the problem?

Whenever I make a safari view controller on XCode26 Beta 5, there appears to be a blurry white overlay overtop the controller. This worked fine in XCode26 Beta 2, with no code differences. Anyone have any suggestions?

I recently updated my iPhone 12 to iOS 26. It seems there is a bug rendering Safari unable to "add to home screen" any website. Clicking the button displays a blank modal with Add button greyed out.

On iOS Devices with ProMotion (120HZ) if you animate Elements on your Page with animation-timeline you get Ghosting Effects. You can not see the Ghosting with a Simulator or on Screenshots, only on real Devices. To Reproduce I made a Minimal Example: https://codesandbox.io/p/sandbox/120hztest-xrwgtc When you scroll quickly on the Page with an iOS 120HZ Device (https://en.wikipedia.org/wiki/List_of_smartphones_with_a_high_refresh_rate_display) you will see ghosting on the Top of the right Element (animation-timeline) and no ghosting on the other animated Element. (I edited the Screenshot, to Illustrate how the Effect looks like, since it is only visible on the real Display)

After App uses Network.framework PrivacyContext Api, dns has been encrypted, that is good. But when using wkwebview to load web page, wireshark captures normal dns request sent by wkwebview. Does wkwebview use DoH to resolve domain? if can, how to config params? If can not, is there anyway to stop wkwebview sending normal dns, such as local proxy.

Hi, I'm having difficulties fetching many 2 many relationships. I have an Actor entity (which I can query in CloudKit JS) that has 2 relationships: inputComponents and outputComponents, both pointing towards a Component entity. How to query these relationships? Thanks Tom
