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?

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?

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.

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?

When transferring files from iPhone to Watch, if you run the app and try to transfer after updating the OS, the transfer may not be possible. (or transmission seems to be too slow) Just completely close the app, restart it, and try again. Does anyone know the cause or solution to this problem? It happened after the last 17.5 update and today after the 17.5.1 update. The app doesn't crash or anything, and it doesn't happen often, so I didn't send any feedback or anything, but it's strange.

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.

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?

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.

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.

Creating a new version fails in Web App Store Connect. When you log in to the Web App Store Connect screen and enter a new version in an existing project, a red error screen as shown below is displayed and the new version cannot be registered. "An error occurred. Please try again later. The version number was previously used." It has been happening continuously since yesterday. I hope you resolve this as quickly as possible. Currently, Testflight testing or distribution cannot be performed because the version cannot be created. This phenomenon continues in both Safari and Chrome browsers. The version you registered is a version you have not used before.

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.

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.

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.

The app sells non-consumable in-app purchases. I also checked to enable family sharing. However, there are frequent cases where users share purchases using the family sharing function and fail when attempting to purchase or restore from a device of the shared account. Or, if a user who received the sharing makes a purchase, it will not be processed as shared payment information, but will be paid with the payment registered with the Apple ID of the current device. I used StoreKit2 and use Transaction.currentEntitlements to get payment info after purchase or restore. However, non-consumable in-app purchase information that has been shared with the family does not arrive normally. When I looked at the Storekit2 documentation, I know that there is nothing special handled or added in the API or code related to family sharing. If I'm wrong on this part or if you know a good solution to this non-consumable payment - family sharing, please advise.
