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.

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.

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.

When showing or hiding the Code Review window in Xcode 26.0.1, a loading screen appears and Xcode freezes. The loading screen appears for about 30 seconds, then disappears and the Code Review window appears. During this time, Xcode also freezes and cannot function. It doesn't seem to be an error or bug, but people who frequently switch between Code Review windows find the long loading time inconvenient. Is there any way to improve this? (MacBook Pro 16, M2 Max, 64GB memory, macOS 26.0 (25A354))

This is the app we are currently selling. If you follow the steps below, you may experience a black screen phenomenon. Run the app and go to the home screen. Turn off the screen of the device and do not use it for a long time. Turn on the device's screen and launch the app from the home screen. Randomly, the entire app screen is black and nothing works. If you completely close the app and run it again, it will run normally. It has been reported to us since iOS 15. And in iOS 15 and iOS 14.8, a user sent us an email about the same phenomenon. This only happens on the iPad, not the iPhone. Supports iPad multitasking UIApplicationSupportsMultipleScenes is not supported. Can anyone advise us on the cause or solution of this symptom?

My app is for iOS (not a Mac app). It can be installed and run on M1 Mac. ProcessInfo().isiOSAppOnMac returns True . In this case, is there any way to get the OS version information of the Mac device where this app is currently installed? All APIs that get the current version information return the iOS version. For example, Mac 12.0 returns iOS 15. Mac 11.0 and Mac 12.0 both return to iOS 15. And some APIs started in iOS 15 crash on Mac 11.0. So we currently want to know how we can get the Mac OS version information of the actual device in the above case. (Additionally, not Mac Catalyst.)

I haven't developed an Apple Watch app yet. I have an existing app for sale. Users of that app sometimes send me requests for functions using Apple Watch in the app by email. Considering future maintenance, I would like to sell the Apple Watch app as a paid app. However, I know that watch app support cannot be turned on/off by in-app purchases in existing apps. Is there any way for the standalone Apple Watch app to communicate with my existing paid/free apps?

I have a few questions about files that are allowed to be backed up by setting isExcludedFromBackup to false . Is it correct that the files allowed to be backed up are backed up by iCloud and iTunes sync? Are the files allowed for backup always/periodically backed up to iCloud? Or does it only sync when the user manually backs up the device? If the files allowed for backup are regularly backed up to iCloud, will there be a capacity issue? (User's iCloud capacity) If there is issue 3 above, is it a good solution to add an option to the app so that users can turn it on/off?

I don't want the function to be included if the iOS app is running on a Mac. (Designed for iPad) For example the sample code below @available(iOS 13.4, *) func keyPressed(_ key: UIKey) { .. } The keyPressed function is included when running in iOS or iPadOS. I would like to know if there is a way to prevent the keyPressed function from being included at launch time, even when running an iOS app as "Designed for iPad" on M1/M2 devices. "targetEnvironment(macCatalyst)" When this is called, false is unconditionally displayed, so the distinction cannot be made. #if ProcessInfo().isiOSAppOnMac func keyPressed(_ key: UIKey) { .. } #endif If you use the code above, ProcessInfo cannot be executed in RunTime, so false is output unconditionally. So far I'm looking for a possible way, but there doesn't seem to be any possible way. If anyone has solved this problem, please reply.

We are providing the ability to speak text in our app using AVSpeechSynthesizer . Stop the AVSpeechSynthesizer at random I get a crash like the screenshot below. What causes this error to occur? It happens occasionally during testing, but it doesn't go away even if I fix it in various ways. Is this a bug in iOS or is there something I need to fix or add? If a crash occurs, the message below is also displayed in the log window during debugging. [AXTTSCommon] _BeginSpeaking: speech cancelled error: Error Domain=TTSErrorDomain Code=-4005 "(null)" [AXTTSCommon] _BeginSpeaking: couldn't begin playback TTS Create Code let utterance = AVSpeechUtterance(string: playText) if Singletone.sharedInstance().ttsIdentifier != nil { utterance.voice = AVSpeechSynthesisVoice(identifier: Singletone.sharedInstance().ttsIdentifier!) } else {         utterance.voice = AVSpeechSynthesisVoice(language: "en-US") }          utterance.rate = 0.4 utterance.pitchMultiplier = 1.0 utterance.preUtteranceDelay = -1.0 utterance.postUtteranceDelay =  -1.0 utterance.volume = 1.0          if self.synthesizer == nil { self.synthesizer = AVSpeechSynthesizer() self.synthesizer!.delegate = self }          self.synthesizer!.speak(utterance) TTS Stop Code self.synthesizer!.stopSpeaking(at: .immediate) self.synthesizer!.delegate = nil self.synthesizer = nil

Has anyone solved the UITableView text persistence or overlapping issue in iOS 16.1 iPhone 14 Pro and 14 Pro Max? If anyone has solved the problem by modifying the code, please reply. I posted on the forum a while ago and forwarded the issue to Apple Feedback. Link to the forum post: https://developer.apple.com/forums/thread/718401 (Sample code and video links are in the article above.) However, it was confirmed today that iOS 16.1 did not improve on the iPhone 14 Pro Max. After making the cell of UITableView display text with UITextView or UILabel The text color is set to black and the background to white. (The afterimage is displayed in black, so it must be reproduced with a white background.) UITableView srollToRow Calls the next or previous Row in the current Row without any animation effects as shown in the code below. tableView!.scrollToRow(at: IndexPath(row: self.pIndex, section: 0), at: .top, animated: false) And the call to scrollToRow is UITapGestureRecognizer , which makes it scroll one page at a time when the user taps. At this time, the cell height of UITableView is set to the total height of the device. This will briefly display the text content that was just previously displayed in black. (Sometimes it is displayed a little longer.) So the current page text and the previous page text overlap. There is a phenomenon that the contents of the previous page disappear. In a slightly animated effect, it feels like a transition to the next page, leaving an afterimage of the previous page content. But I didn't add any animation effects in the motion. This is definitely happening on the iPhone 14 Pro and 14 Pro Max. We think it might be an iOS error. I don't think it will be improved as iOS will be updated soon. (No feedback from Apple as of today.) So, if you have experienced the same problem and solved it through code, please help. Even if it is improved with an OS update in the future, there are users who are currently uncomfortable, so if there is a way, I am thinking of including it in the app update.

In the news these days, there are many things that Apple may allow sideloading installation from iOS 17. In that case, it might not be a problem to install only the ipa file of the paid app and install it on someone else's device. Is Apple currently supporting an API that can check whether a paid app has been purchased? (This is a paid app, not a subscription or in-app purchase.) If there is such an API, please let me know.

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.
