AVSpeechSynthesizer delay issue, [AXTTSCommon] Invalid rule: Play text using AVSpeechSynthesizer. Sound comes out normally. If you call speak(_ utterance: AVSpeechUtterance) to play text as speech [AXTTSCommon] Invalid rule: The log is displayed and it is called two or three times and the sound comes out late. It is judged that there are cases where delays of more than 1 second occur depending on the user, device, or situation, usually ranging from 0.6 seconds. [AXTTSCommon] Invalid rule: There is no additional reasoning behind the log. [AXTTSCommon] Invalid rule: [AXTTSCommon] Invalid rule: In this way, it is called a second time. This issue occurs after iOS 16.0. Is there any way to fix that issue? or not I would like to know if there is a way to reduce the delay at startup even if that log is displayed after the speak(_ utterance: AVSpeechUtterance) call.

macOS 14 Sonoma cifilter issue (Designed for iPad) I just updated my M1 Mac to MacOS 14 Sonoma. I ran the iOS/iPadOS app built in Xcode 15.0 on a Mac whose OS was updated using Testflight. (My app is Designed for iPad and is set to run on macOS.) When UIImage is processed using cifilter, the generated image may be grayed out. The same code does not occur on iOS and iPadOS. In other words, it does not occur on iPhone and iPad iOS/iPadOS 17. Has anyone experienced a similar issue? And I would like to know the solution ASAP. I am distributing the app as Designed for iPad. Every year, when Mac OS is updated, an issue arises. So, I am considering not allowing Vision Pro to run the current iOS/iPadOS app.

How do I prevent my app's folders or files from being displayed or searched in the Files app? Currently, the app is set to display internal files and folders in the "Files" app, Apple's default app. Is there a way to turn this on and off within the app code so that our app's files or folders are not searched within the Files app? All files and folders in the Documents path and their subfolders and files are eligible.

We are working on a screen that registers fonts using UIFontPickerViewController. Sometimes when I run UIFontPickerViewController I just get a black screen. Or, the font of the UI inside UIFontPickerViewController is broken and displayed as strange special characters. When displayed as a special character, screen scrolling becomes slow and the font is not displayed in the list when scrolling down. When this happens, the Xcode debug window shows “error received: connection invalidated.” This error message is displayed. This happened to me often while developing UIFontPickerViewController . Could you please advise how to resolve this issue? Or, I hope Apple resolves the issue quickly and updates. The development device where the issue occurs is iPhone SE3 iOS 17.4.

When PKCanvasView is first drawn, existing drawing objects disappear. PKDrawing, which previously had drawings saved with PKCanvasView, was saved as separate data or file. After that, while creating a new PKCanvasView, I loaded the saved PKDrawing and reflected it in the new PKCanvasView. Below is the code. canvasView!.drawing = draw! Previously saved text or lines will be displayed normally. However, when I draw with the pen for the first time (when I touch the screen with the pen), the old writing or lines disappear. And after I leave a line or text, if I pan across the screen, the old text or line appears again. If this phenomenon occurs and you touch the screen again with the fan, this phenomenon will no longer occur. This phenomenon occurs the first time when a new PKCanvasView is declared and the previously saved PKDrawing is reflected. Could you please help me with why this phenomenon occurs and how to improve it?

Is there a way for the app currently playing music or voice in the background to know when a Critical Alert or push comes? Currently, my app contains code that stops playback when a call comes in while music or voice is playing in the background. So, if a call comes in during playback, it stops normally. However, there is a phenomenon in which playback cannot be stopped when a Critical Alert or push comes. When a Critical Alert or push comes to the device, is there a way in the code for the app currently playing music or voice in the background or foreground to know at that moment? We are not sending out Critical Alerts or pushes. I would like to know how to resolve the situation when receiving a Critical Alert or push sent to all users in one country.

Questions about isExcludedFromBackup option and device migration I posted a similar question a year ago, but I still haven't found a solution that I like, so I'm leaving this question. If anyone knows how, please let me know. In our app, we set the isExcludedFromBackup option to true so that files currently in the Documents path are not backed up to iCloud. In the current situation, I am just curious as to whether the files of our app can be backed up in the two situations below. (with isExcludedFromBackup option set to true ) Migrate iPhone to new iPhone Backup and restore the entire device to iTunes If you set the isExcludedFromBackup option to true in the file, iCloud backup will not be possible, and the app's internal files will not be copied even in the two situations mentioned above. Is there an option or method in the app's internal code to prevent automatic backup only to iCloud and allow files to be copied or synchronized in the above two situations?

Music app stops playing when switching to the background In apps that play music or music files, if you move to the home screen or run another app while the app is running, the music playback stops. Our app does not have the code to stop playing when switching to the background. We are guessing that some people experience this and others do not. We usually guide users to reboot their devices and try again. How can this phenomenon be improved in the code? Or is this a bug or error in the OS?

Are there any cases where when connected to a specific Bluetooth device on an iPhone or iPad, the Bluetooth device connected at the same time is frequently disconnected or the app connected via CoreBluetooth is disconnected? Our app connects to an iPhone or iPad and connects to CoreBluetooth API to perform specific functions or operations. When a JBL Bluetooth speaker is connected, the connection is automatically disconnected during operation. When the JBL Bluetooth speaker is disconnected, the Bluetooth connection between our apps is not disconnected. It does not happen on all iPhones or iPads, but it seems to happen on some devices. Our app users are experiencing this issue with JBL Bluetooth speakers. So we are trying to replicate this phenomenon with our Bluetooth speaker, but it doesn't work. Has anyone else experienced something similar? I am wondering if this phenomenon can occur.

Build issue when creating an Apple Watch standalone app archive This is an Apple Watch standalone app. (Without an iPhone app) Even if you create an Apple Watch standalone app as a new project in Xcode, two targets are created: "iPhone target + Apple Watch target". The iPhone target cannot be built or modified. Usually, builds or archives are created with the Apple Watch target. It's been a while since I updated the app, so I tried to fix it, add new features, and update it. When I created an archive, the version kept being created as 1.0 - 1. I entered 1.1 - 8 for the Apple Watch target. In the previous Xcode version, when I clearly modified the version and build version of the Apple Watch target, it was reflected in the archive file. However, in the current Xcode, it is not reflected. Does anyone know how we can fix this issue?

iPhone mirroring function has been added to this macOS. I am also currently using the iPhone mirroring function. However, when isSelectable is set to true in UITextView and isEditable is set to false (isScrollEnabled is also set to false.) Editing is not possible, but selection is possible. (In non-mirroring mode) But in iPhone mirroring mode, selection is not possible Is there an option for UITextView that allows text selection or a separate setting in macOS? Or can this be fixed in the iPhone mirroring app when macOS is updated in the future? (If it is a bug or error?) It seems to work normally in cases where UITextView is used but Edit is possible, such as in the memo app.

iPhone mirroring is available from macOS 15. When running an app with iPhone mirroring Can I know whether the app currently being mirrored is running at the top of the Mac app or screen? Or is there a way to know whether it is hidden by another app on the Mac or re-displayed? If not, I hope it will be added in a future update. And I hope there is an API that can tell whether the current app is connected to iPhone mirroring or not.

I have an app that I've been using for over 10 years now. When I searched for that app on the App Store, it didn't show up. (both in the US, Japan, and Korean stores) There's a phenomenon where the app crashes and dies when performing a specific function. So I'm trying to develop an app that's very similar to that app. When I migrate or restore after changing or initializing my device, the previously installed app is installed on the home screen. There are several apps that don't show up on the App Store and seem to have been removed by the developer. Some apps have a blank icon image on the home screen, and when you click on them, a pop-up appears saying that they can't be installed and asks if you want to delete the icon. Some apps are still installed. Some functions are broken because the developer stopped maintaining them for a long time. They can't be searched on the store either. What are the differences and similarities between these two apps?

We are trying to connect to Webdav. The file server is in the same network. So when we try to connect, the local network permission pop-up is displayed. If the input information is incorrect in the first login attempt when this permission pop-up is displayed, After that, even after fixing the normal connection, we cannot connect or log in with the message "NSURLErrorDomain Code=-1009", "Internet connection is offline." This symptom seems to persist even after rebooting or deleting and deleting the app in the actual distributed app. If you re-debug while debugging Xcode, you can connect normally. (If you do not re-debug, it fails even if you enter the connection information normally.) And it affects local connection, so you cannot connect to any local network server such as SMB or FTP. Also, you cannot browse the server list within the local network. (SMB) Is there a way to initialize the local network status within the app to improve this phenomenon? I tried turning Airplane mode ON/OFF, turning Wi-Fi ON/OFF, and turning local network permissions ON/OFF, but it did not work. Also, this phenomenon seems to be a Sandbox for each app. When connecting to the same local server from an app installed on the same iPhone/iPad device, the above phenomenon does not occur if the first connection is successful. ** Summary ** If you fail to connect to a server on your local network, then you will continue to fail to connect to the local server. This happens even when local network permissions are allowed. The error message is NSURLErrorDomain Code=-1009 The current device is an iPhone device running iOS 18.1.1.

Apple provides a function to create TTS voice as a file in TTS. (AVSpeechUtterance/AVSpeechSynthesizer) Or, if the user records the video of TTS playback and uses that video I wonder what the scope of use is if I use this TTS voice to make YouTube, TikTok, or commercial videos. Is it impossible to use it commercially at all? Can I use it commercially with the source indicated? Can I use it commercially without a separate source indication? Is there a difference in commercial use license between Siri voices and regular TTS voices?
