I've noticed a strange issue with the SceneDelegate lifecycle in iOS 27. [Environment] iOS 27 (Also tested on physical devices) UIKit / SceneDelegate based App [Description & Steps to Reproduce] When the app is in the foreground and the user locks the screen (presses the power button): In iOS 26 and earlier: sceneWillResignActive is called exactly once. (Expected behavior) In iOS 27: The following sequence is called rapidly in succession: sceneWillResignActive (Screen lock initiated) sceneDidBecomeActive sceneWillResignActive (Locks completely) When the user unlocks the screen later, sceneDidBecomeActive is called once as usual. [Impact] Because sceneDidBecomeActive is unexpectedly fired while the device is locking, it triggers foreground logics right before the app is pushed to the background. This is causing unwanted side-effects and glitches. Has anyone else encountered this unbalanced lifecycle issue in iOS 27? I'd like to know if there's a better approach or if Apple is aware of this. Thanks!

I'm developing a CarPlay app and encountered an inconsistent behavior with template detection. When I present a CPActionSheetTemplate and then print the presentedTemplate property, it returns nil. However, when I present a CPAlertTemplate, the presentedTemplate property correctly returns the template object. This inconsistency is causing issues in my app where I need to check if there's already a presented template before showing another one to avoid conflicts. Why does CPActionSheetTemplate not get detected in presentedTemplate while CPAlertTemplate does? Is this intended behavior or a bug? Any guidance on how to properly detect if a CPActionSheetTemplate is currently presented would be greatly appreciated.

Hello, I appreciate the enhanced productivity brought by ChatGPT and Claude AI integration in Xcode 26, which assists with code completion, refactoring, and documentation directly within the IDE. However, in real-world development environments, teams use a variety of MCP (Model Context Protocol) collaboration tools such as Jira, GitHub, Notion, and Confluence. Currently, there is no official, seamless integration of multiple MCP services with the AI features inside Xcode. For example, it would be extremely beneficial if: AI could automatically fetch and understand issues, tickets, documents, and code context from multiple MCP services, Perform related code modifications, pull request creation, and documentation updates All done intuitively and with minimal steps directly from Xcode. I kindly request that future Xcode releases provide official support for connecting to various MCP APIs, enabling smoother collaboration between AI and multiple team productivity tools all within the IDE environment. Thank you for considering this enhancement.

Previously, when using AppDelegate, I was able to check the app’s launch options (launchOptions) to determine cases such as: Location updates (UIApplication.LaunchOptionsKey.location) Background push notifications (UIApplication.LaunchOptionsKey.remoteNotification) However, after migrating to the SceneDelegate approach, launchOptions is no longer available — it always returns nil. In my app, I need to branch the code depending on the launch options, but I can’t find a way to achieve this in the SceneDelegate environment. 👉 Is there a way to access launch options in SceneDelegate, similar to how it worked in AppDelegate? Or, if that’s no longer possible, what would be the proper alternative approach? Any guidance would be greatly appreciated.

After updating from iOS 18 to iOS 26, our app icon appears to have automatically received the new 'Liquid Glass' effect. We confirmed that this change occurred without us releasing a new app update. My questions are: Is this a system behavior where iOS 26 automatically applies the new icon style to existing apps? If so, is it possible for a developer to control or customize this effect? I am also wondering if there are any methods other than using Icon Composer.

I’m experiencing a crash in WKWebView on iOS 26 Developer Beta 5 and Beta 6 with the following exception: CALayer position contains NaN: [nan 65] The crash occurs when the following CSS properties are applied to content displayed in WKWebView: -webkit-user-select: none; -webkit-touch-callout: none; This issue happens consistently whenever these styles are set, leading to the crash inside WKWebView. Is this a known bug in the current iOS 26 betas, or is there a recommended workaround?

Starting with iOS 26, we've noticed that the accessoryImage in CPListItem is not working as expected in CarPlay. Previously, accessoryImage would appear in place of the accessoryType, but now it appears awkwardly next to the detailText, and the image itself is not rendering properly. We have submitted feedback to Apple multiple times, but the issue still persists in the latest beta releases. In general, there seem to be several CarPlay UI problems introduced in iOS 26. For example: In CPPointOfInterestTemplate, the pinImage is displayed at an excessively large size. Scroll positions in lists behave unexpectedly. CPInformationTemplate allows infinite scrolling, which seems unintended. Please take a look into these issues. Thank you.

Issue Description I'm developing a hybrid iOS app and encountering WebView bridge communication issues after updating to Xcode 16 with iOS 18 SDK. App Architecture AViewController: Initial view controller displayed at app launch Handles WebView setup and web-to-native bridge communication Pushes BViewController when receiving "B" bridge message from web BViewController: View controller stacked on top of AViewController Managed by navigation controller AViewController's WebView continues bridge communication even when BViewController is active Problem Behavior Xcode 15 (iOS 18): WebView bridge communication in AViewController works normally while BViewController is active Xcode 16 (iOS 18 SDK): Server communication breaks or hangs without response while BViewController is active Communication resumes only after popping back to AViewController from BViewController Questions Is the current architecture (configuring WebView in AViewController and maintaining bridge communication through AViewController's WebView while BViewController is presented) not a recommended pattern? Is Xcode 16's iOS 18 SDK the cause of this issue? If so, could you help me understand which specific changes are affecting this behavior? This is urgent as we need to deploy soon. I would greatly appreciate a prompt response.

In my app, I want to launch Apple Maps and start turn-by-turn navigation when the user taps a button. I referred to Apple’s documentation and sample projects and implemented the following code: if let url = URL(string: "maps://?t=m&daddr=(addr)") { self.carplayScene?.open(url, options: nil, completionHandler: nil) } This works only if Apple Maps has been launched at least once on the iPhone or in the CarPlay environment. If Apple Maps has never been opened before, it launches the app but does not automatically start navigation. However, once the user has opened Apple Maps at least once — either on the phone or through CarPlay — then navigation starts as expected from that point on. Is this behavior expected? Or is it a bug?

I'm using CPListItem like this: CPListItem( text: "test", detailText: "test", image: nil, accessoryImage: nil, accessoryType: .none ) However, when I tap the item in the list, a loading indicator appears on the right side, as shown in the image I attached. I didn’t configure anything that should cause this behavior. Why is the loading indicator shown by default when tapping a list item? Is there a way to prevent it from appearing?

I'm developing a CarPlay Fueling app with CarPlay entitlement properly configured. While testing, I ran into two issues and would appreciate any guidance: UserDefaults access while iPhone is locked: In my CarPlay implementation, I read values from UserDefaults that were previously saved in the iOS app. However, when the iPhone is locked and the CarPlay session is active, it seems that the CarPlay extension cannot read the stored values. Is this the expected behavior? If so, how can I persist and access data across the app and CarPlay reliably? API calls while iPhone is locked: The CarPlay interface in my app communicates with a server to display lists and detail views. When the iPhone is locked, are network calls still allowed from the CarPlay extension? Currently, I do not have any background modes enabled in the app capabilities. If I enable background modes and implement background network logic to ensure API calls complete properly, would this be considered acceptable usage for CarPlay in App Store review? Or could it raise any rejection concerns during the approval process? Thanks in advance for your help.

I'm trying to implement a custom back button in a CPInformationTemplate using CPBarButton. It works as expected on iOS 18 — the button appears in the navigation bar and correctly pops the template when tapped. However, on iOS 16 devices, the custom back button does not respond to taps at all. The reason I need a custom back button is because I want to perform cleanup and reset logic before popping the template. Is there any workaround for making this work on iOS 16? Or is there a recommended way to hook into the system back button behavior so that I can execute code when the template is dismissed?

I am currently developing a CarPlay application using CPPointOfInterestTemplate. I am displaying a list of restaurants on a map, and when a user taps on a restaurant in the list, I present a detail view using CPPointOfInterest. The list of restaurants is updated based on the user's location changes using the setPointsOfInterest method. Is there a way to detect when they press the close button (typically an "X" button) to dismiss the detail view and return to the list? Is there a delegate method or any other mechanism to determine whether the CPPointOfInterestTemplate is currently displaying the list of points of interest or the detail view of a specific point of interest? I need to know this so that I can avoid updating the list based on location changes when the detail view is being shown. My current implementation updates the list of restaurants whenever the user's location changes. This works well when the user is Browse the list. However, if the user has navigated to the detail view of a restaurant, a location update currently causes the list to reload, which results in the detail view being dismissed and the user being taken back to the list. I would like to prevent this from happening and only update the list when the list view is visible.
