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.

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.

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.

Crash in Xcode code review When you enable Enable Code Review in the upper right corner of Xcode, Xcode crashes or loads infinitely. I don't think this problem existed in previous versions of Xcode, but it is very serious in the current version 15.4. It doesn't crash in all parts of Code Review, but Xcode crashes or loads infinitely in certain parts. I really hope this will be fixed in the next Xcode version. It happens so often that I'm going crazy. Seriously Especially if there are many or wide changes in the swift file, the crash occurs in that part.

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?

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?

Delete the Documents path of the app Will the files or folders in the documentDirectory path or applicationSupportDirectory path disappear or be deleted when the OS is updated? I know that sometimes all the files in the cachesDirectory path are deleted when the OS is updated or the device is rebooted. Sometimes, users of my app report that all the files in the documentDirectory path or applicationSupportDirectory path are deleted or disappear, or all the files are deleted and initialized. I thought that the files or folders in the documentDirectory path or applicationSupportDirectory path were not affected by the OS update, but am I wrong?

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?

Crash occurs in @MainActor class or function in iOS 14 Apps built and distributed targeting Xcode 16 version swift6 crash on iOS 14 devices. We create a static library and put it in our app's library. Crash occurs in all classes or functions of the static library (@MainActor in front). It does not occur from iOS / iPadOS 15. If you change the minimum supported version of the static library to iOS 11, a crash occurs, and if you change it to iOS 14, a crash does not occur. Is there a way to keep the minimum version of the static library at iOS 11 and prevent crashes?

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?

"Build input file cannot be found" error occurs in Archive. When running Archive to generate a build file, the build file generation fails with a "Build input file cannot be found: ..." error. When debugging, the build runs fine on the actual device without any errors. Comparing and modifying the Build Settings with other projects doesn't fix the issue. Deleting the Swift file and attempting to Archive results in a crash due to the missing file. Even after deleting and adding the Swift file, the same error persists when attempting to Archive. Even after deleting and re-adding the Swift file, the issue persists even after deleting all DerivedData file space on my Mac and restarting Xcode. Can you help me with this issue? It worked fine before the recent macOS update, and I successfully archived and published it to the App Store a few days ago. I believe this issue occurred after updating macOS to 26.0.1. My Xcode version is 26.0.1.

Xcode SPM (Swift Package Manager) Error I added the "Apple App Store Server Swift Library" library to Xcode using Swift Package Manager. Both the project and target are set to iOS 14 or higher. However, when I build after adding the library, an error occurs with the library. A message appears stating that the target is set to iOS 12. I'm using Xcode 26.0.1. Even after adding it to all my projects, the build continues with the same error. I've tried building the library from version 1.0.0 to the latest version, but the same error persists. Even after completely cleaning the project and running it, the same error persists. Does anyone know how to fix this?

Apple Watch app closes when changing photo permissions in the iPhone app. App A is installed simultaneously on both the paired iPhone and Apple Watch. I'm running App A on both my iPhone and Apple Watch. When I change the photo permissions on App A installed on my iPhone, App A running on my Apple Watch automatically closes. At first, I assumed App A on my iPhone was abnormally closing, causing App A on my Apple Watch to also close. However, I've determined that changing the photo permissions is the cause of the app closing. I don't think this behavior existed before WatchOS/iOS 26. Is this behavior a natural addition to WatchOS/iOS 26? If I go to the home screen while running app A on my iPhone and change its photo permissions in the Settings app, app A running on my Apple Watch automatically closes.

We are testing an app currently on sale on iOS 15. When I start scrolling up and down by touch in a UIPickerView , the scrolling is not smooth. There is a short break when you start scrolling. If I flick it quickly, it stops and after a while it has already scrolled to where some data has advanced. If we start scrolling and keep scrolling, then we don't have the above symptoms. The above symptoms start after the app does a big operation while loading a file. That is, when the symptom starts, it is there in the UIPickerView throughout the app. Only UIPickerView scrolling, other screen transitions or UITableView scrolling do not show such symptoms. There is no such symptom until iOS 14. Could you give us some advice on the cause of the above symptoms or how to improve it? The device tested is an iPhone 8 plus. We did send feedback to Apple through the Feedback app on devices that currently have iOS 15 installed.
