Hi, I have started facing an issue with Xcode since updating to macOS 26.1. The debugger is not stopping at breakpoints in Objective-C code, however breakpoints in Swift file are working fine. I am using Xcode 16.4. For breakpoints in Objective-C files I have started to get this message since the OS update - 'Xcode won't pause at this breakpoint because it has not been resolved.' I have already tried cleaning derived data and build folder. I do not want to upgrade to Xcode 26. Could someone help with the fix? Thanks

I am building a data logging app that logs the iphone's movement data at 120 hertz and 200 but for some reason its always capped at 100. does anyone know if there a hardware issue or is there a code problem that could be linked to this. made in Xcode.

I started to use the Accessibility features of UIKit but cannot get the numbers or labels to show up on UICollectionCells. The image here shows a 3x3 matrix with no numbers, but the numbers on the menu commands show up. Actually these are just iOS accessibility features, not my app. I've tried reducing the size of my images or no images, but nothing shows up (in any of my UICollection code). I can get them to work on UITableView cells. I've tried the Accessibility selection in the storyboard or code, but nothing helps.

We are planning to develop an app that connects to a UVC camera to capture and display video via AVFoundation. Could you please advise on which iPhone models support UVC cameras?

How long does it usually take for a developer account to be enrolled? I've been pending since the 23th of December.

Problem On the macOS when Settings view is closed, the @State model is not deallocated Feedback FB21393010 Environment macOS: 26.2 (25C56) Xcode: 26.2 (17C52) Steps to reproduce Run the project Open app's 'Settings Look at the console logs When model is created SettingsModel - init gets printed When Settings window is closed SettingsModel - deinit is not printed, meaning it is not deallocated Code SettingsModel import SwiftUI @Observable class SettingsModel { init() { print("SettingsModel - init") } deinit { print("SettingsModel - deinit") } } SettingsView import SwiftUI struct SettingsView: View { @State var model = SettingsModel() var body: some View { Text("Settings") .font(.largeTitle) .padding(200) } } App import SwiftUI @main struct SettingsBugApp: App { var body: some Scene { WindowGroup { ContentView() } Settings { SettingsView() } } }

Regarding App Update Synchronization During Workout Mode: My watchOS app has workout mode enabled. When I update the app from the App Store on my iPhone while a workout session is active on my Apple Watch, the update does not sync to the watch. Why does this happen, and when can I expect the watch app to be updated? Regarding Automatic App Launch After a Prolonged Shutdown: I would like my watchOS app to launch automatically on my Apple Watch after it has been powered off for an extended period and then turned back on. Is this functionality possible to implement? If not, please provide a definitive answer regarding this capability.

I am developing an app which included subscriptions and in app purchases. Created a Test Flight archive a day ago. Got Apple email with their approval, shortly after. I know there is a problem and the Test Flight release is not available in Connect app, or App Store Connect on Mac. I am useing Xcode 26, iOS 26 and an iPhone 17 Pro.

Environment Device: iPad Air (5th generation, M1) OS Version: iPadOS 26.1 Device Orientation Lock: OFF Stage Manager / Multitasking: Disabled App Mode: Full screen (UIRequiresFullScreen = true) Supported Orientations: iPhone: Portrait + Landscape iPad: Landscape only Description On iPadOS 26.x, when device orientation lock is OFF, iPad apps that support only landscape orientation can be displayed in portrait orientation, even though portrait is explicitly not supported for iPad. This issue: Occurs not only at app launch Can also happen during runtime, such as: Returning to the app from background Unlocking the device Rotating the device while the app is running Switching focus (Control Center, Notification Center, multitasking gestures) When orientation lock is ON, the system consistently respects the app’s supported interface orientations and the issue does not occur. This behavior is a regression in iPadOS 26.x. Expected Behavior Regardless of device orientation lock state: The system should never display an app in an unsupported orientation supportedInterfaceOrientations must always be enforced Physical device orientation should only be applied within supported orientations Actual Behavior With orientation lock OFF: The system can force the app into portrait orientation This happens even though portrait is not listed in UISupportedInterfaceOrientations~ipad The app UI becomes incorrectly laid out or broken With orientation lock ON: Orientation behavior is correct and stable This suggests iPadOS 26.x is allowing device orientation to override supportedInterfaceOrientations during runtime.

When trying to launch an app built with Xcode in iOS12, differences occur depending on the macOS version on which Xcode is installed. When building with Xcode 26.2 (or Xcode 16.4) installed on macOS Sequoia, installing it on iOS 12 and tapping the app icon launches the app. When building with Xcode 26.2 (or Xcode 16.4) installed on macOS Tahoe, installing it on iOS 12 and tapping the app icon does not launch the app. The following log was displayed upon launch: Dec 15 11:46:35 xxx assertiond[58] <Notice>: Submitting new job for "com.xxx.sample" on behalf of <BKProcess: 0x10151a710; SpringBoard; com.apple.springboard; pid: 48; agency: SystemShell; visibility: foreground; task: running> Dec 15 11:46:35 xxx assertiond[58] <Notice>: Submitted job with label: UIKitApplication:com.xxx.sample[0x2dfd][58] Dec 15 11:46:35 xxx assertiond[58] <Notice>: Unable to get pid for 'UIKitApplication:com.xxx.sample[0x2dfd][58]': No such process (3) The same issue occurs with both .app and .ipa. I would like to know the technical reason behind this, if anyone knows, please let me know.

We're using XCode 26.1.1 We do not have resource to adopt Liquid Glass design. Hence, we are using the following workaround <key>UIDesignRequiresCompatibility</key> <true/> This is our Storyboard. Pre XCode 26 Before XCode 26.1.1, the bottom toolbar looks great. In XCode 26 However, in XCode 26.1.1, the bottom toolbar buttons seems to "Squish together". Do anyone have any idea, how I can make UIToolbar works by enabling UIDesignRequiresCompatibility? Thanks.

Hello Apple Developer Team I am an independent iOS developer creating highly specialized applications for a very small private audience of fewer than ten users These applications are tightly coupled with custom hardware that I design and manufacture myself for example automotive air suspension control systems Due to the extremely narrow scope and non commercial nature of these apps maintaining a full Apple Developer Program membership is economically impractical The applications are not distributed publicly are not monetized and are used only by a small group of people who share the same technical hobby All application code is written entirely by me There are no copyright violations no private API usage no hidden functionality no tracking and no malicious behavior The apps do not compromise iOS security do not harm users and do not discredit Apple or the iOS platform The software only functions when paired with proprietary hardware under my control At present the only viable way to install these apps is by using free developer certificates with a seven day expiration period This creates a significant usability burden Users must constantly re sign and reinstall the apps Non technical users frequently make mistakes during this process which leads to frustration and discourages experimentation learning and hardware innovation I would like to propose that Apple consider a limited and tightly controlled homebrew style distribution option where non App Store applications could be installed only after Apple review and approval similar in spirit to TestFlight or app notarization This could include strict limitations such as a very small number of allowed users no monetization no public discovery and clear labeling as private experimental or hardware coupled software Apple would retain full control over approval enforcement and revocation at all times Such a mechanism would preserve the security and trust model of iOS while supporting independent engineers hardware developers and advanced hobbyists It would reduce incentives for unofficial sideloading and encourage innovation at a grassroots level without weakening platform safety I deeply respect Apple’s focus on security quality and user trust This proposal is not about bypassing the App Store but about enabling a controlled reviewed and extremely limited path for legitimate non commercial hardware specific applications I hope this message can receive timely consideration and that if such an approach aligns with Apple’s platform goals it could be explored for inclusion in upcoming iOS versions where feasible Thank you for your time and for supporting the developer community Best regards Anzor Tekuev Independent iOS Developer

Hi everyone, I have a question regarding App Store approval. In my country, Apple In-App Purchases are not supported, so for users in unsupported regions we need to use a third-party payment provider. For countries where In-App Purchases are supported, we plan to use Apple IAP. Could you please advise on the correct approach to ensure the app complies with App Store guidelines and can be approved?

【背景】 現在、各広告実績(コスト、クリック数など）とCV実績（Adjustローデータ）を紐付け、広告ダッシュボードを構築しております。 iOSアプリキャンペーンにおいて、AD名での紐付け(SQL上でのjoin)が必須となり、ご質問させていただきました。 【質問】 SKAN側の仕様について、計測時SKANからMMP側にデータを送信しているかと思います。 この送信データに、ADG名、AD名は付与されているのでしょうか。 Adjsut担当者様より、リファレンスは無いがポストバック値にはある、とご説明いただきました。 SKAN側でリファレンス等あればご教示いただけますと幸いです。 また、SKAN4.0からは source-identifier がポストバックデータに含まる認識ですが、 この4桁の数値からADやADGを特定することは可能なのでしょうか。 MMPや広告主側で各ADにsource-identifierに紐付けは不可で、媒体側で自動発行される認識をしており、発行粒度/規定も媒体ごとに異なっていると理解しております。 ご返答いただけますと大変ありがたいです。 ▼参考リファレンス https://developer.apple.com/documentation/storekit/verifying-an-install-validation-postback#3592477

I have configured all the necessary settings for the APP Clip, but it still cannot be activated through NFC or scanning the code. What is the problem?

In my impression, this issue has been around for years. In the Mac App Store, the app description is collapsed by default. After clicking "More" to expand it, the last few lines of the description are always cropped. It seems that the more content there is, the more content gets cropped. The following screenshots are from the same app, one with the system language set to Chinese and the other to English.

Can I use Xcode to create a playbook for soccer to design exercises and then show the exercise to the players later at practice or a game? I need to integrate the roster with game plans and designed exercises with practice.
