It seems fetch() does not include credentials (cookie) even when credentials: include is used and Safari extension has host_permissions for that domain when using from a non-default Safari profile. It includes credentials (cookie) when using from the default profile (which has the default name Personal). Is there anyone who has this problem? I try to request in popup.js like this: const response = await fetch( url, { method: 'GET', mode: 'cors', credentials: 'include', referrerPolicy: 'no-referrer', } ); and it does not include the credentials (cookie) from host_permissions. I already posted https://developer.apple.com/forums/thread/764279, and opened feedback assistant (FB15307169). But it is still not fixed yet. (macOS 15.4 beta 3) I hope this is fixed soon.

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.

We are seeing network errors in Outlook mail on iOS and MacOS safari browsers. As per current investigation, we notice these network error when the user tries to use outlook after leaving it open on Safari for a while. Observations: Issue present in both MacOS and iOS safari. Issue is not present in other webkit browsers like brave and edge on iOS. Issue is reproable on both mini and big owa on safari browser. Issue is not related to post requests being sent in different packets on safari browser. Requests are only blocked for outlook.office/outlook.live domains What does not fix this issue? Reloading the application Clearing cookie, local storage or session storage Unregistering service workers Redirecting to a different page and coming back to outlook domain Re authenticating the users What fixes this issue? Reconnecting to wifi or mobile network Reconnecting vpn Removing safari from background and reopening Flushing the dns in setting

In my application, I use HTML pages to display the interface. Since it’s a cross-platform app, the pages and interactions work properly on other platforms. However, in WebKit, because HTTPS protocol is used, JS requests from the page cannot use the ws protocol but must use the wss protocol under HTTPS. Is there any way to allow a webpage under HTTPS to use ws requests normally? Google Chrome can do this.

Having the app localised and configured to Dutch from Belgium (nl_BE), I open a url with WKWebView. The website locale detects Dutch from Netherlands (nl_NL)

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?

Recently, our some customers feedback that their phones can not connect to our site by safari or App, show the error of “Cannot Connect to Host -1004”，all of these problem customers has installed iOS 18.3 beta. Is there anybody meet the same problem?

Hi Team, Our team member trying to enroll through the invite in Apple Developer portal Note: Phone number is valid but still we are getting this error. It happens in all the browser

I've a apple pay integration on my website. The new sdk, that allows third party browsers. My integration works well everywhere, except on third party when I read the QR code it results in a "payment incomplete". I have gone through several threads in apple dev forums, and several guides on implementation steps and troubleshooting. But I'm still without solution. When Debugging in iOS device I get: "Application failed to provide a valid merchant session. We can't proceed to authorize the transaction." I've doublechecked, the values I send to create the payment Session are correct, the domain and merchantIds. (It works well with the same implementation on safari, what's the difference here?) I've also doublechecked the values i'm sending to the completeMerchantValidation, and they are all in the right format and types. What else can iIcheck?

We're embedding the Power BI reports into our portal by using JS library. While testing them, we found that mobile layout of the reports don't work as we expect on iOS devices (tested in Chrome and Safari). There are two principals issues: 1) the site is automatically refreshed when the users filter the data (we reduced them to lower expression) and 2) the site also crashes after a while using the dashboard by applying different filters.

I'm using navigator.geolocation.getCurrentPosition to retrieve the users coordinates in a PWA built with Nextjs. getCurrentPosition is called by clicking on a button. If getCurrentPosition is called afterwards, the cached value is returned. On Safari, If I refresh the page, or logout, login and call getCurrentPosition again, the getCurrentPosition error callback is called with an error code 2 - POSITION_UNAVAILABLE. After around five minutes, getCurrentPosition can be called again. Is there some kind of throttling restriction on Safari navigator.geolocation.getCurrentPosition?

We confirmed a problem at Safari on iPadOS 18.2 or after version. For confirmation, we made a HTML document (see below HTML1) what include ‘method="POST" target="_blank"’ and tested the form however server received GET method and there is no parameter, server did not receive “id” parameter. We confirmed that fact in captured packet and log file that on the server. HTML1: We also made another HTML document (see below HTML2) what include submit button, but the server received GET method as above. HTML2: And we also confirmed that it behaves differently depending on the network environment. If the form targets a name that does not exist (ex. target=” A12345”), behaves differently http or https. http: Safari opened new tag, but the server received GET method. Normally, Safari open new tag and the server receive POST method. https: Safari opened new tag, and the server received POST method. It is normally. If the form targets ‘_blank’, the server received GET method on http or https both. We think Safari change the method POST to GET and delete parameters. It is not conformed to the HTML specification if is that true. We confirmed it was not happened at Safari on iPadOS 17.4, and Windows PC (Edge, Chrome). The method what the server received is POST. We find same problem in Apple Support Community (see below URL). https://discussionsjapan.apple.com/thread/255987615 (Described in Japanese) Is it a bug in Safari on iPadOS 18.2 or after version? Do you have plan to fix? Or if fixed the bug, when do you release fixed version.

PWA works perfectly fine in safari browsers in mac but in mobile devices it is not working it just shows, There is no internet connection. found a fix from ios release - https://developer.apple.com/documentation/safari-release-notes/safari-17_2-release-notes but actually it is not solving the issue. in my case even it is not throwing the issue - fix is - Fixed a cache miss bug in DOMCache that triggered service worker fetch errors.

We are encountering a download issue in Safari 18.2 on macOS Sequoia 15.2 where file downloads initiated by our AngularJS application (such as Excel exports) are silently blocked. There are no errors in the browser console, and the download does not occur. Interestingly, after testing on Safari 18.3 with Sequoia 15.3, the downloads worked as expected. However, the problem reappeared on Safari 18.4 with Sequoia 15.4. We suspect that recent changes in Safari’s security or download handling may be preventing downloads triggered via asynchronous JavaScript (e.g., AJAX calls) that are not initiated directly by user interaction. We would appreciate any insights, suggestions, or possible workarounds from the community. Looking forward to your guidance on this matter.

Hi all, Chrome has it already - animation-timeline aka scroll-animations. I can nowhere find any informations on what's the status in Safari/Webkit. Seems like they do not have it on the agenda at all? Does anyone know anything - I wanted to push a feature request for that - but also seem there is no feature request list anymore for webkit. See: https://www.w3.org/TR/scroll-animations/ Cheers and kind regards!

The app analytics tab for my account is empty. It doesn't show any bundle IDs or apps that have been launched. Is this normal for WatchOS apps? Here's a screenshot of the tab: https://cloud.goodsmile.studio/hT5fL2HY

MacOS: 12 ( Monterrey ) Safari: 17.6 Demo Site: https://applepaydemo.apple.com/ At the bottom where the Apple Pay button should appear, I see a warning something like "This browser doesn't support Apple Pay, please use safari" along with a link to requirements for apple pay. All the requirements are fulfilled, OS and Safari's version are above the minimum required. Link was opened in Safari. And the other thing is if I open the same site in Chrome, I can see the apple pay button and when I click on it a QR appears which is the expected behaviour. How to resolve this?

I'm referring to the following: https://developer.apple.com/documentation/automaticassessmentconfiguration I can't find this information anywhere. I'm wondering if I can enable and disable this function in Safari or other browsers on my website.
