In-app purchase: Commission and taxes
I’m writing to understand how taxes are applied to our subscription revenue and to clarify a potential issue we’re facing. For a ₹299 subscription: Apple deducts a 30% commission, leaving us with ₹209.30. After that, an additional tax of approximately 18% (₹36.11) is deducted by Apple, which reduces the amount further. When we receive this ₹173.19 in our bank, we are required to pay 18% GST again on this amount in India. This appears to result in us paying tax twice. Could you clarify why 18% tax is deducted by Apple, and if we are not required to pay it again, where can we see this adjustment on the GST portal?

iOS 18.1 Beta 5 bugs
I've just updated to iOS 18.1 Beta 5 update and I'm not able to see FaceTime audio/ video calls in the phone call log at all as it's like no where. And even in FaceTime there is no summary like call duration or recent calls log, just last call listed. Please resolve this issue and have FaceTime calls logs to be shown in the phone call logs as that was perfect and categorised.

Screen Capture on Mac 15 not working through SSH
Steps: Connect to Mac through ssh and execute “screencapture abc.jpg” It shows the attached popup, though we have added “ssh-keygen-wrapper” to control the computer in Privacy and Security->Accessibility and in Privacy and Security->Screen and System Audio recording in System Settings Ideally, we wouldn’t like to see this popup as we have given enough permissions to take the screenshot as mentioned above, same works fine in Mac14 and below versions Even upon clicking “Allow for one week”, new session of SSH will have this popup again.

Personal Voice authorization requires app restart
I'm trying to include Apple's Personal Voice feature in an app I'm working on, but I want to use a button or toggle to request access, rather than firing the request on first launch. The problem is that, if AVSpeechSynthesizer is used during the same session, before Personal Voice is authorized, the app has to be restarted to use the feature. Here is a basic example that demonstrates the issue on my iPhone (running 18.1 beta, but the issue was present at least in 18.0, maybe before): import AVFoundation import SwiftUI struct TestView: View { let synthesizer = AVSpeechSynthesizer() @State private var personalVoices: [AVSpeechSynthesisVoice] = [] var body: some View { VStack(spacing: 100) { Text("Personal Voices Available: \(personalVoices.count)") Button { speakUtterance(string: "Hello, world!") } label: { Image(systemName: "hand.wave.fill") .font(.system(size: 100)) } Button("Fetch Personal Voices") { Task { await fetchPersonalVoices() } } } } func fetchPersonalVoices() async { AVSpeechSynthesizer.requestPersonalVoiceAuthorization() { status in if status == .authorized { personalVoices = AVSpeechSynthesisVoice.speechVoices().filter { $0.voiceTraits.contains(.isPersonalVoice) } } } } func speakUtterance(string: String) { let utterance = AVSpeechUtterance(string: string) if let voice = personalVoices.first { utterance.voice = voice } else { utterance.voice = AVSpeechSynthesisVoice(language: Locale.preferredLanguages[0]) } synthesizer.speak(utterance) } } If you tap the hand symbol first (before authorizing Personal Voice), you'll probably notice that the Personal Voices Available number never increases. If you authorize Personal Voice before tapping the hand symbol, it should speak using your Personal Voice as expected. The example code is mostly taken directly from this WWDC23 video (Personal Voice info begins around the 10-minute mark). Does anyone have any idea what could be causing this? Note: Personal Voice can't be tested in Simulator. The code will need to be run on a physical device that has Personal Voice set up, to test.

guidedAccessStatusDidChangeNotification does not get called on visionOS
I am trying to get a Notification if Guided access is enabled or disabled on the VisionPro. For doing so you would normally just call: NotificationCenter.default.addObserver(forName: UIAccessibility.guidedAccessStatusDidChangeNotification, object: nil, queue: .main){ noti in print("guided access did change") } and this works fine on iOS devices. But running the exact same code in Vision os Results in not getting a notification at all, even though Guided Access gets enabled or Disabled. For testing i ran a simple default app, that works perfectly on both os types. import SwiftUI struct ContentView: View { var body: some View { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") } .onAppear{ print("is appeairng") NotificationCenter.default.addObserver(forName: UIAccessibility.guidedAccessStatusDidChangeNotification, object: nil, queue: .main){_ in print("guided access did change") } } .padding() } } But as said it prints "guided access did change on iOS" but not on the Vision Pro.

Default localization fallback not used for untranslated string in catalog
For an iOS app, I'm using a String Catalog for localization. In the Localizable.xcstrings, I have all the Keys set with IDs, and default to English set, and other languages added. All of the English strings has some English text value assigned. The Key and the values are different. The Swift code only makes references to the Keys. As for the non-English languages, not all of the strings have been translated. Many of the fields are not set, i.e. it's in grey and showing the English text, and I can see the "new" tags for those untranslated strings in the String Catalog. All of that is good and expected. However, when I run the app in a non-English language, for the untranslated strings, I'm seeing the string Key instead of the English value. The screens in the app are shows Key IDs all over the place, along with some translated text, but nothing in default English. Is that how it's suppose to work? It seems like the "Default Localization (en)" should be shown. That's the whole point of having a fallback default language is it not? I understand pre-string catalogs, the fall back default is the key, but now I'd expect it to use the default language as backup since that's what's shown in the catalog.

Accessibility VoiceOver issue for UIDatePicker
The react-native-date-picker is based on UIDatePicker on iOS. The UIDatePicker element is a wrapper containing other elements that the VoiceOver user can interact with (year, month, day and so on). I'm using react-native-date-picker with the UK date format(day month year). If I change day, such as 1 July 2024 to 2 July 2024, the VoiceOver says 2 of 12, but 12 is the month total. If I change month, such as 1 July 2024 to 1 August 2024, the VoiceOver says 8 of 31, but 31 is day total. It's weird. Please help me out on how to solve this issue or let me know if I am missing anything. iOS 16.3.1 react-native-date-picker 4.4.2

When to use Numbered Lists in VoiceOver Accessibility
When would it be a good idea to utilize numbered lists with VoiceOver accessibility. As an example, for tab bars it will read about "2 of 5". In speaking with an Accessibility engineer at WWDC this year, the said that its good practice, but we ran out of time in the call to dig further deeper. When or how do you know when you should read out the item count "2 of 5". It makes sense to me in say a tab group or a chip group, but I don't see it being good in say potentially a UITableView with potentially a various number of sections of which each section itself can include multiple cells. I've had trouble finding additional guidance on this topic, if anyone can provide recommendations or their thoughts, that would be great.

question about App Store Server Notifications
I have 2 subscriptions, monthly and year first:DID_CHANGE_RENEWAL_PREF + DOWNGRADE: Customer downgrades a subscription within the same subscription group; The current subscribe is year;if i change to month;when the subscribe year was expire,Automatic renewal will change to month second:DID_CHANGE_RENEWAL_PREF+UPGRADE: Customer upgrades a subscription within the same subscription group. The current subscribe is month;if i change to year;I need to pay for the annual subscription immediately;and The subscription immediately switches to the annual third:DID_CHANGE_RENEWAL_PREF subtype is None Customer reverts to the previous subscription, effectively canceling their downgrade. what this mean? This is Test Env,month is five minutes;year is one hour ①My current subscription is an annual, startTime:2024-10-02 15:04:58 ,expireTime:2024-10-02 16:04:58 ②first DOWNGRADE to month,at 2024-10-02 15:14:16 ②after 38 minutes,I change to the annual subscribe;at 2024-10-02 15:52:00 in the end,the Notification purchaseDate 2024-10-02 15:52:00;expiresDate 2024-10-02 16:52:00; So When I get NotificationType=DID_CHANGE_RENEWAL_PREF,NotificationSubType=None,Do I need to create a new subscription for the users?

Text Replacement preferences are not exportabe, is there a PLIST file or similar that stores these values?
macOS > Settings > Keyboard > Text Replacement is a macOS/iOS feature I use extensively but it is unavailable in quite a few macOS applications — including some Apple apps like Xcode. Other apps I want Text Replacement to work in but it doesn't are the Adobe CC suite, all my code text editors like VC Studio, Sublime Text, BBEdit, emacs etc and Firefox. Does anybody know what the file path is for the file that stores the Text Replacement key/string pair data? If i can access the .plist file or similar where the Text Replacement key/string pairs are stored I will be able to convert to JSON using REGEX and import to the Firefox plugin that will replicate Text Replacement functionality in Firefox for me. Ditto other code editor applications with their own particular text substitution functionality. Background Some of these apps have plugins or functional equivalents of Text Replacement but i need a way to do the import/export dance to keep them in sync with my Text Replacement text pairs. Sadly, even though we can select the Text Replacement table (in macOS but not in iOS versions), we can't copy that information. This seems to me a violation of good GUI design principles. Why allow selection of the entire table if we cannot copy it to the clipboard? Nor can we import or export the table of text tuples. The Text Replacement GUI has no buttons to do this (consider this post also a FR for that). Screen-capturing and running text recognition software over the PNG it is not an option given: a) all the UTF-16 unusual glyphs and combination glyphs i use; b) that I'd like to script this as a multi-directional syncing application I can run periodically. Typically macOS and app preferences are stored in plist files. I want to find such a file and convert it to JSON for importing into a Firefox plugin that replicates Text Replacement within Firefox. I tried modifying Text Replacements by adding a new item to the list and clicking "Done" and then filtering ~/Library for .plist files and sorting by "Date Modified" but nothing is showing up with these values in it.
