My iOS app is crashing on the initial load. It's happening both in my Testflight build and also in the production version of the app on the App Store. It was working fine a few days ago; this just started happening all of a sudden.
What's strange is that after doing a fresh install, it doesn't happen the first time I open the app. It only happens after I force close the app and open it again (and every time afterward).
I'm using Expo and React Native to build the app. I've attached a crash log.

The following way of setting the background color of an anchor tag in Safari on iOS 15 isn't working:
<html>
<head></head>
<body><p><a class="content" href="#"><strong><span>Some content with background</span></strong></a> </p>
<br />
<button onclick="javascript:onClick();">Click me to change content's background color</button>
<script>
function onClick(){
var element = document.getElementsByClassName('content')[0];
element.style.backgroundColor = "#888888";
}
</script>
</body>
</html>
I had to run the following hack after setting the backgroundColor in order for it to work:
// Temporary workaround to redraw the element:
var disp = element.style.display;
element.style.display = 'none';
var trick = element.offsetHeight;
element.style.display = disp;

Surely this is a bug in Safari unless I might've missed something?

Hello,
I am trying to copy files using AppleScript(javascript) and for the life of me cannot figure out the correct syntax. I have tried all the possible variations i can think of the following but nothing seems to work. Any suggestions would be greatly appreciated!.
var app = Application.currentApplication()
app.includeStandardAdditions = true
// Tried this
app.duplicate("/tmp/file1.txt"), {
to: "/tmp/file2.txt"
})
// And all sorts of variations such as
app.duplicate(Path("/tmp/file1.txt"), {
to: Path("/tmp/file2.txt")
})
// And not including file names
app.duplicate("/tmp/file1.txt"), {
to: "/tmp/"
})

Target is view html subtitles in vtt format in TV when AirPlay is running from:
<video preload="metadata" x-webkit-airplay="allow" src="a.mp4">
<track kind="subtitles" default="" src="en.vtt" srclang="en">
<track kind="subtitles" src="de.vtt" srclang="de">
<track kind="subtitles" src="es.vtt" srclang="es">
<track kind="subtitles" src="fr.vtt" srclang="fr">
</video>
The problem is when AirPlay is enabled video and audio plays on TV, but no subtitles showed.
I tryied to include vtt/srt subtitles into the mp4 metadata with ffmpeg and subtitles working with VLC but not working when AirPlay this files.
ffmpeg -i 8499.mp4 -i 8499.en.vtt -map 0:v -map 0:a -c copy -map 1 -c:s:0 mov_text -metadata:s:s:0 language=en 8499.en.mp4
ffmpeg -i 8499.mp4 -i 8499.en.srt -map 0:v -map 0:a -c copy -map 1 -c:s:0 srt -metadata:s:s:0 language=en 8499.en.mp4
Also tried to send a .m3u8 with no luck. Any of you know how is the basic format for a simple .m3u8 with a .mp4 and .vtt working when AirPlay?
Wich is the standard subtitles solution for AirPlay?

My website shows a video using video tag which worked perfectly until not long ago.
The video is working but when pressing on full screen, the video is playing but the screen is black while the sound is still playing.
The issue occurs only on iPhones with iOS 15 (using Safari and Chrome also).
Things I've tried:
I've tried playing the video directly with a URL to the actual file(to check its not codec issue) and it worked properly.
My video tag has 'position: absolute;' on it and I tried removing it(even though it breaks my layout) and that didn't work either.
Tried pausing the video immediately and playing it after the video loads.
Tried applying a background: white; or any non-transparent color to the video tag.
Tried removing auto play.
Tried to disable 'GPU process: Media' on safari settings just to check if that affects anything and it didnt.
This is the html:
<video data-test-id="long-video" #longVideo muted controls playsinline [class.d-none]="!isShortVideoHidden"
*ngIf="isPageLoaded" src="https://cdn1.someurl.com/videos/commercial_1.mp4"
type="video/mp4">
</video>
and the css(with the parent):
@media only screen and(min-width:992px) {
.fixed-video {
position: fixed;
z-index: 10000;
margin: auto;
width: 100vw;
height: 100vh;
left: 0;
top: 0;
bottom: 0;
right: 0;
background: rgba(0, 0, 0, 0.5);
transition: 0.4s;
video {
width: 80%;
left: 0;
right: 0;
top: 0;
bottom: 0;
margin: auto;
}
}
}
Please tell me if you have struggled with this and know how to solve it. Thank you :)

Hi
I'm developing a captive portal with cookies, it works fine in devices like Macs, laptops and android devices but cookies don't work on iPhone.
I'm creating cookies in js with document.cookie but the problem is when I connect my iPhone and close CNA, it destroy them and next time I try to connect, cookies don't exist anymore.
Someone can help me to figure out how can I avoid CNA destroy my cookies?
I am trying to run JavaScript only after the page has loaded, and according to here - https://developer.apple.com/documentation/safariservices/safari_app_extensions/injecting_a_script_into_a_webpage, I should use DOMContentLoaded. However, it does not seem to work.
This is my content.js file:
function runOnStart() {
document.addEventListener('DOMContentLoaded', function(e) {
document.body.style.background = "rgb(20, 20, 20)";
document.html.style.background = "rgb(20, 20, 20)";
var divElements = document.body.getElementsByTagName('div');
for(var i = 0; i < divElements.length; i++) {
let elem = divElements[i];
elem.style.background = "rgba(255, 255, 255, 0.05)";
}
});
}
runOnStart();
If I take the code outside of the event listener, it runs fine, but a lot of the elements haven't loaded in yet so it doesn't work as it should.
The function is definitely running, but the event listener simply doesn't work. I appreciate any help you can give!

Hi ! I have a problem on Safari browser that I'm not able to solve.
On my site I have a form submission with an action. This action takes about 10-15 seconds to finish (because of a big image retouching) so what we want is that when the user makes click on the submit button, a "Loading screen" shows. I've created a div( id=loader ) with a hidden spinner and what we do is that when the user makes clic on the submit button, visibility and opacity of the div is set to 1 and then the form gets submitted.
The problem is that the spinner gets frozen and does not animate (on chrome and firefox it works ok).
document.getElementById('load').style.visibility='visible';document.getElementById('load').style.display='block';document.getElementById('load').style.opacity='0.98';document.formulario_colores.submit();
¿Any solution?

I'm creating a framework that allows you to easily create html and css web pages in ios style.
As long as it's static components that don't have events (e.g. a webpage with a paragraph), that's okay. The problem arises when I have to create a button, recognize and capture the click event. In the same way, however, I have the problem of recognizing and capturing all the other browser events (e.g. the page is loaded into memory). In web development this is handled by javascript. But I would like to replace javascript with my framework and with swift.
So how do I interact with browser events? do i have to install swift in the browser? how can I do?
thank you

I have this js code:
document.addEventListener('AppleIDSignInOnSuccess', (data) = {
//handle successful response
console.log(data["detail"].authorization.id_token)
response = parseJwt(data["detail"].authorization.id_token)
email = response["email"]
console.log(email)
loginWithEmail(email)
// console.log("APPLE SIGN IN SUCCESSFFUL");
});
//Listen for AppleId authorization failures
document.addEventListener('AppleIDSignInOnFailure', (error) = {
//handle error.
alert(JSON.stringify(error))
console.log("APPLE SIGN IN UNSUCCESSFFUL");
});
And it just stopped working. Now every time I sign in I get "APPLE SIGN IN UNSUCCESSFFUL" and the error is {"isTrusted":false}. What are ways around this?

I am currently using the WKWebView to evaluate Javascript in my Swift code. This code uses the callAsyncJavaScript to evaluate Javascript. My code takes parameters from the user and then injects those parameters into the Javascript string that is evaluated by callAsyncJavaScript.
This of course is an opportunity for js injection attacks that could cause unwanted js to run. I know Apple uses WebViews in their own native apps like Music. But there is nowhere I can find best practices on how to prevent js injection attacks.
Anyone have experience with this? Here's a sample function I use.
func createMessage(message: ARMessageDto) async -> ArweaveResult {
do {
guard self.walletStr != nil && !self.walletStr!.isEmpty else {
return Result.failure(TransactionError.General("No wallet exists for this user"))
}
let balance = try await self.arweaveQuerySvc.getBalance()
if balance < 1_000_000_000_000 {
return Result.failure(TransactionError.General("Error wallet balance is less than 1,000,000,000,000 Winston"))
}
guard case .none = message.validate() else {
return Result.failure(TransactionError.ParametersInvalid(message.validate()))
}
let respondingToTransId = message.respondingToTransId ?? ""
let result = try await self.webView!.callAsyncJavaScript("""
\(baseScript!)
const arweaveSvc = main('\(walletStr!)');
const result = await arweaveSvc.createMessage(
'\(message.msg)',
\"\(message.userName)\",
\"\(respondingToTransId)\"
);
return result;
""", contentWorld: WKContentWorld.defaultClient)
_ = await self.arweaveQuerySvc.mine()
return try getTransactionResult(result: result)
} catch {
return Result.failure(TransactionError.General("Failed to create profile"))
}
}

Hi!
Does anyone have a good solution for the following:
I want to use JavaScripts HTMLMediaElement.play() method to play a sound when a button is clicked. Everything working fine in Chrome and Firefox, but Safari 15... Every time I click the button there is some kind of delay or it is not even played. I used the code as described below:
const mainButton = document.getElementById('main-button');
const buttonSound = new Audio (button-sound.mp3);
mainButton.addEventListener('click', e => {
buttonSound.play();
});
It would be great if someone could help!

Hello everyone. I am working on a project (website). And when people visit our website from IOS phones under version 14, clients get an error with localStorage. That is, the system literally does not find localStorage. How to fix this, maybe someone faced a similar problem?
I want to put on 3D object on websites, but I don’t know how to do.
It doesn’t explain AR such as Apple’s product page.
It explain like top page’s earth of github.com.
In short, I want to put 3D object without page-jumping.
This question is maybe not adopted here -apple developer forum-, however I want someone to answer this.

I'm currently trying to build my react native app on TestFlight with Fastlane using this tutorial:
boorje.com/deploy-react-native-app/
I reached the last step and ran the command bundle exec fastlane beta. This should've built the app on TestFlight, but it didn't.
Instead, I received this error: File/Users/myname/Library/Developer/Xcode/DerivedData/GAbeta-etzidujiozhpelfdovtuwdoldqcl/Build/Intermediates.noindex/ArchiveIntermediates/GAbeta/BuildProductsPath/Release-iphoneos/GAbeta.app/main.jsbundle does not exist.
Additionally, I was informed that the following build commands failed:
PhaseScriptExecution Bundle\ React\ Native\ code\ and\ images /Users/myname/Library/Developer/Xcode/DerivedData/GAbeta-etzidujiozhpelfdovtuwdoldqcl/Build/Intermediates.noindex/ArchiveIntermediates/GAbeta/IntermediateBuildFilesPath/GAbeta.build/Release-iphoneos/GAbeta.build/Script-00DD1BFF1BD5951E006B06BC.sh
I've done some research on potential solutions including https://github.com/facebook/react-native/issues/25522#issuecomment-509036251, but none worked.
Does anyone have any suggestions in order to solve this issue or could anyone potentially assist in my search?

Hello!
I would like to a deploy a program (more on which later) to the Apple Store, and I have a couple of questions regarding Apple Pay API usage.
My product will be a paid program, and I have some problems with the Apple Pay API due to technical reasons.
My program is an "Electron-like" application, it consists of two parts, backend, and UI.
The "Backend" runs directly in the user's computer, it's written in Python and Flask.
The "UI" is actually a browser that opens a webpage from the "Backend", and interacts with it using AJAX.
The issue here is that I don't understand how in-app payments can be implemented.
As far as I understand, the only option to deploy a paid application and the Apple Store is to use Apple Pay API, which is only available from Swift or Objective-C.
I don't understand how can I use Apple Pay API, how I can check for a valid payment, etc.
Can you please send me some kind of guide, tutorial, or instruction that can help me to use Apple Pay in my program?
Thank you very much,
Alex.
