After updating my phone to iOS 18.2 2 days ago, I noticed that a website I'm working on that uses Rafael JS(https://dmitrybaranovskiy.github.io/raphael) to do some svg rendering which used to work before I updated just stopped working. I notice that Safari tries to load website tries to load 2 or 3 times before showing the error: A problem repeatedly occurred on <website> which I find really odd since this used to work before and I haven't made any changes to the code. This also happens in Chrome on iOS 18.2.

we are using angular and Html5 to develop our application, in our application we play videos that are placed on s3. Video when played on desktop borwser are adequatley audible but when played on iPad their volume is too low to be audible. I have tried video.volume =1 but it does not work for iPad because this property is only readable for ios devices. I have tried using javascript audioContext. It worked for my local machine. But when code is deployed on some hosted environments, it just does not work. Did anyone face the same issue? Any help regarding it will be appreciated.

There is a display issue when viewing HTML containing ruby tags on Safari for iPad. The layout appears distorted. Steps to reproduce: Preparation: Device: iPad mini (MUQY2J/A) / iPad Air (MM9F3J/A) Open Safari. Access the following URL: https://67440d05c7b448995b6e5619--admirable-muffin-193494.netlify.app/ The text in the left cell overlaps with the text in the right cell. Please refer to the attached file: Notes: This issue does not occur when ruby tags are absent. The same issue occurs in Chrome as well (possibly a WebKit-related problem?).

Description: When using a multilingual keyboard that includes Korean in iOS 18, the input element's onChange event is triggered multiple times instead of just once. This issue occurs not only when entering numbers with input type="tel" or inputMode="numeric", but also when entering text with input type="text". This causes unexpected behavior in forms and other input-related functionalities. Affected Devices and OS Version: Device: iPhone 16 Pro OS Version: iOS 18.0 You can reproduce the issue with this CodeSandbox example: https://codesandbox.io/p/sandbox/elegant-dream-jnqh39 Steps to reproduce: Use a multilingual keyboard (e.g., Korean and English) on iOS 18. Type some text into the input field (input type="text"). Also try entering numbers using input type="tel" or inputMode="numeric". Observe that the onChange event is fired multiple times for both text and numeric input. Expected behavior: The onChange event should only be triggered once when text or numeric input changes. Additional Information: This issue has been reported under feedback ID FB15377631. Currently waiting for a response from Apple regarding this feedback.

Hello everyone, in my website I need to give users the ability to choose a color via input type=“color”. I don't understand why it works fine on desktop (even on Safari for Mac) but doesn't open the color picker on iPhone. How can I solve this? Thank you, Andrea

I need to play a Video with transparent background on our website. It works perfectly on Windows, Mac & Android (in all browsers). On iPhone however, no matter what Browser, The transparent parts of the video act almost like an "overlay", making everything behind it a lot brighter. This effect gets worse, the higher I set the iPhone screen brightness. This is of course not the behavior I'm looking for. The Video Element has two listed sources. One .WEBM (VP8 with alpha channel) and one .MP4 (HEVC with alpha channel). I am sure, that something is wrong with the MP4 file, but I don't understand why it works in Safari on Mac, but doesn't on iPhone. Shouldn't they both play the same File? Here is my workflow: masking the subject in DaVinci Resolve exporting as QuickTime - Apple ProRes 444 - "Export Alpha" using Shutter Encoder (v15.7) to convert the file to H.265 (.mp4) under "Advanced Features": Hardware acceleration to "OSX VideoToolbox" & check "Enable alpha channel" also converting the first file to VP8 (.webm) with "Enable alpha channel" then adding the Videos to the website like this: <video height="450px" autoplay loop muted playsinline disablepictureinpicture> <source src="(url of the mp4)" type='video/mp4; codecs="hvc1"'> <source src="(url of the webm)" type="video/webm"> </video> Here is how it looks on Safari (Mac) This is what it looks like in any browser on iPhone I have re-exported, re-converted and re-implemented it multiple times and I just can't get it to work on iPhone. Does anyone have an idea, what the cause could be, or what I can do differently?

iOS 18 WKWebView images are not loading, no errors in older versions. The example while loading HTML is as follows. A problem occurs when you pull an image from a url. To get a URL image you need a cookie or something. I add them too, but it doesn't work on iOS 18. I get the error "An error occurred trying to load the resource." and a blue question mark on the screen. webView.configuration.websiteDataStore.httpCookieStore.setCookie(cookie) <html> <head> <style> body { font-family: -apple-system; margin: 0; padding: 0; text-align: center; } img { width: 100%; height: auto; } </style> </head> <body> <h1>Resim Görüntüleme</h1> <img src="https://xx.***.xx/example.png"> </body> </html> """

Hello everyone, is it possible to embed a USDZ file (Roomplan) in an HTML5 website and view it in 3D? Or do I need to convert the USDZ file into a GLTF file?

We as a team of engineers work on an app intended to visualize medical images. The type of situations where the app is used involves time critical decision making for acute clinical conditions. Stability of the app and performance are of almost importance and can directly help timely treatment action. The app we are developing uses Javascript. It has been observed the footprint of the app is lagging by 2 to 3 seconds in releasing memory while javascript is expecting the memory to be cleared. This is affecting the stability of our application and preventing us in delivering the right quality of application. The problem specifically can be described as follows, using javascript create an array and then remove it and after removal of the array, create a new array of the same size immediately and again remove it. Because the memory is not released in time, if you repeat these steps a few times the app memory footprint will increase and that crashes the app. To reproduce this scenario, we have created a simple app which creates an array with size of 100MB and checks the memory footprint using the Xcode instrument tool. When we create an array of 100MB size, sometimes it shows the memory footprint peak of around 700MB-800MB and when we clear the array by assigning it with an empty array it releases the memory after 2-3 seconds. Considering the critical nature of the app, I urge you to look into this and provide necessary support and resolution. Please refer below sample code that will help to reproduce the mentioned scenario. import UIKit import WebKit class ViewController: UIViewController, WKUIDelegate { @IBOutlet var webView: WKWebView! let myHTML = """ <!DOCTYPE html> <html> <head> <style> .button-style { width: 400px; height: 200px; margin: 15px; font-size: 50px; } </style> </head> <body> <button type="button" class="button-style" onclick="loadDataInCache()">Load Data In Cache</button> <button type="button" class="button-style" onclick="removeDataFromCache()">Clear Cache</button> <script> const size = 1024 * 1024 * 100; let numberArray = []; function loadDataInCache() { numberArray = Array(size).fill(0); } function removeDataFromCache() { numberArray = []; } </script> </body> </html> """ override func viewDidLoad() { super.viewDidLoad() // self.view.addSubview(webView) webView.loadHTMLString(myHTML, baseURL: nil) } override func loadView() { let webConfiguration = WKWebViewConfiguration() webView = WKWebView(frame: .zero, configuration: webConfiguration) webView.uiDelegate = self view = webView } }

Flutter web view- I am downloading assets from server and using that assets to create html file to load on web view. I downloaded them to the local document directory on the device. From there I can load the HTML files in a webview using the file:// schema, with the benefit that images, css etc. that are referenced in the HTML are loaded as well. This works fine in Android (simulator and real device) as well as in an iOS simulator. But on an iOS device the flutter webview fails to load assets , images & css files with a relative URL from local directory. This is strange as the iOS simulator should behave the same in that case (as it is not really a hardware related issue). Help me out from this issue.

I have a few pdfs that contains images/grayscale images that opened properly on my app with IOS 16.5 but since upgrading to 17.5, the app crashes with “A problem has repeatedly occured on...” this means the IOS itself is not able to handle the pdf otherwise we would get an error from our app. Previously, while we got a warning in the console saying that the max canvas has been exceeded. The app did not crash. Would it be possible to know what was the changes coming in version 17.0+ that could have caused this? And if so, should this be a bug that gets fixed? I’ve looked at the release note and can’t pinpoint which changes could have caused this new behaviour. This occurs on safari and chrome.

We are trying to retrieve merchant tokens from ApplePay. We used the javascript codes from Apple Pay demo site to request for a recurring payment from the frontend. "recurringPaymentRequest": { "paymentDescription": "A description of the recurring payment to display to the user in the payment sheet.", "regularBilling": { "label": "Recurring", "amount": "4.99", "paymentTiming": "recurring", "recurringPaymentStartDate": "2023-08-11T11:20:32.369Z" }, "trialBilling": { "label": "7 Day Trial", "amount": "0.00", "paymentTiming": "recurring", "recurringPaymentEndDate": "2023-08-11T11:20:32.369Z" }, "billingAgreement": "A localized billing agreement displayed to the user in the payment sheet prior to the payment authorization.", "managementURL": "https://applepaydemo.apple.com", "tokenNotificationURL": "https://applepaydemo.apple.com" } Payment was successful, but merchantTokenIdentifier is not shown in the in decrypted ApplePay token, regardless of test card used. We tried Visa and MasterCard.

以下是包含完整日誌的回報範本： Title: WKWebView File Upload Causes App Crash When Selecting Camera or Recording Options Body: Hello, I am experiencing a critical issue with WKWebView in our iOS app when handling file uploads. We are using the following HTML element to allow users to capture images or videos, select from their photo library, or choose a file from the file system: <input type="file" accept="image/*;capture=camera" id="cameraInput"> Issue Description: When a user selects the camera or recording option, the app immediately crashes and returns to the WKWebView screen. This issue does not occur when selecting a file from the photo library or file system.

Notably, we have a similar issue in our Android app using WebView. In that case, the file upload options for camera, recording, and file selection do not appear at all, restricting users to only upload files from the phone's storage. We would like to inquire whether there have been recent changes to the APIs related to WKWebView and WebView or any known issues that could be causing this behavior. We are also concerned this might be a side effect of recent bug fixes or updates to WKWebView. Additional Context: This issue appears to be specific to iOS 17. We have tested the same functionality on devices running iOS versions below 17, and the camera and recording options work as expected without any crashes. This suggests that the issue may be introduced in iOS 17. You can view a video demonstrating the issue at this link: https://share.icloud.com/photos/001voevXriVXsEUmhzGsFBtSA Environment: iOS version: 17.6.1&17.5.1 Device: iPhone 15 Pro Max& iPhone 12 WKWebView version: [Your WKWebView version, if known] App platform: iOS Xcode version: 15.1 We appreciate any insights or guidance you can provide on this matter. Thank you.

I wonder why that happens. When opened on Mac. Acceptance of files with the '.hwp' extension is applied. But not on ipad I'd like to know why, where can I get information? here is the code <!DOCTYPE html> <html> <body> <h1>The input accept attribute</h1> <form action="/action_page.php"> <label for="img">Select file:</label> <input type="file" accept=".pdf, .hwp"> </form> </body> </html>

I had to close all application vs code xcode simulator and reboot everything and it started working. Thanks!

【現象】 Safariブラウザでcanvasに対して任意の描画をした後、clearRect()を実行します。 その後、canvasの親divに対して visibility: hidden を設定すると、消したはずの描画が復活します。 但し、親divは正常に visibility: hidden が働いているので描画されなくなります。 また、この現象はブラウザの拡大率が影響をしているようです。 少なくとも後述のリスト内のMacbookAirでは、拡大率が100%の場合にのみ発生しています。 この現象は過去のバージョンでは起きてないようです。 このバグを修正する予定はありますか？ 【機種】 機種は以下のリストを確認してください。 Model OS&Version Y/N version MacbookAir M2 2022 macOS Sonoma 14.4.1 y 17.4.1 Mac Studio 2022 Apple M1 Max macOS Monterey 12.5 n 16.0 MacBook Air M1 2020 macOS Sonoma 14.3.1 n 17.3.1 iPadPro gen6 iPadOS 17.4.1 y - iPad gen10 iPadOS 17.4.1 n - 【デモ】 現象を確認するためのデモは以下のHTMLファイルを保存してブラウザで開いてください。 再現手順はボタンを draw -> clear -> hide の順番に押してください。 黄色の親divが非表示になるのに対し、canvasからclearしたはずの黒い四角が表示されます。 <html> <body onload="onLoad()"> <div id="parent" style="background-color: yellow;"> <canvas id="canvas"></canvas> </div> <button onclick="drawCanvas()">draw</button> <button onclick="clearCanvas()">clear</button> <button onclick="showCanvas()">show</button> <button onclick="hideCanvas()">hide</button> <script> let parent let canvas let context2d function onLoad() { parent = document.getElementById("parent") canvas = document.getElementById("canvas") context2d = canvas.getContext('2d') } function drawCanvas() { context2d.fillRect(0, 0, 100, 100) } function clearCanvas() { context2d.clearRect(0, 0, canvas.width, canvas.height) } function showCanvas() { parent.style.visibility = "visible" } function hideCanvas() { parent.style.visibility = "hidden" } </script> </body> </html>
