Our iOS app supports CarPlay capability with the Driving task. The app is also configured to wake in the background on geofence entry or exit events, even from a terminated (killed) state. We would like to understand how to detect whether CarPlay is connected to the iPhone when the app wakes up or runs in the background. In this case, the CarPlay app is not actively running in the Car infotainment system foreground. Requirement: The app should perform a background task only when CarPlay is connected, including when launched in the background or from a killed state due to a geofence trigger. Could you please advise on the recommended way or API to determine CarPlay connection status in this background scenario? Thanks for the support!

Since updating to Tahoe and Xcode 26 I have found that the UISplitViewController.showDetailViewController() is not working in the iPhone version of my app (it is a universal app). I'm just trying to show a detail view after a tap on a UITableView item. The iPad versions are all working correctly. Has anyone else experienced this or have any advice about what may have changed? Thanks in advance.

We are facing an issue: push notifications are not being received. We are using the Marketing Cloud SDK for push notifications. On install, the app correctly registers for push notifications. We pass the required information to Marketing Cloud — for example, contact key, token, etc. Marketing Cloud also confirms that the configuration is set up, and we have tried sending push notifications with proper delivery settings. The issue is that after some time, the device gets automatically opted out in the Marketing Cloud portal. When we consulted their team, they said this is caused by the “DeviceTokenNotForTopic” error received from APNs. I have verified the certificates and bundle ID from my end — everything looks correct. Device: iPhone 15, iPhone 17 iOS: 18.7.2, 26.1

Hello, maybe anyone know anything about HCE (Host card emulation) feature on iOS? As far as I read, it's not possible to achieve this functionality on iOS, but maybe there are plans to implement that? Or maybe it's clear that it wont be allowed to be used at all? Thanks:)

I have been experimenting with the BGContinuedProcessingTask API recently (and published sample code for it https://github.com/infinitepower18/BGContinuedProcessingTaskDemo) I have noticed that if I lock the phone, the code that runs as part of the task stops executing. My sample code simply updates the progress each second until it gets to 100, so it should be completed in 1 minute 40 seconds. However, after locking the phone and checking the lock screen a few seconds later the progress indicator was in the same position as before I locked it. If I leave the phone locked for several minutes and check the lock screen the live activity says "Task failed". I haven't seen anything in the documentation regarding execution of tasks while the phone is locked. So I'm a bit confused if I encountered an iOS bug here?

The Paste button (using UIPasteControll) located on UINavigationBar is not shown at application startup on iOS/iPadOS 26. This issue will disappear when device is rotated or window size is changed. And this issue does not occur on iOS / iPadOS 18 and earlier. I uploaded the sample project to github at the following URL. https://github.com/gpn-galapagos/PasteButtonApp.git Has anyone had the same issue or knows a workaround?

After the iOS 26 update, unwanted animations appear on UIButton. I'm using the attributedTitle property of UIButton.Configuration to change the button's text, and an animation appears after iOS 26. (It's unclear whether it's after iOS 26.0 or iOS 26.1, but it likely started with 26.1.) The peculiar thing is that the animation only starts appearing on buttons that have been pressed once. I tried using UIView.performWithoutAnimation and CATransaction's begin(), setDisableActions(true), commit(), but it didn't work. How should I solve this? Below is the code for changing the button's text. func updateTitle() { let keys = type.keys if keys.count == 1 { guard let key = keys.first else { return } if key.count == 1 { if Character(key).isLowercase { self.configuration?.attributedTitle = AttributedString(key, attributes: AttributeContainer([.font: UIFont.systemFont(ofSize: 24, weight: .regular), .foregroundColor: UIColor.label])) } else if Character(key).isUppercase { self.configuration?.attributedTitle = AttributedString(key, attributes: AttributeContainer([.font: UIFont.systemFont(ofSize: 22, weight: .regular), .foregroundColor: UIColor.label])) } else { self.configuration?.attributedTitle = AttributedString(key, attributes: AttributeContainer([.font: UIFont.systemFont(ofSize: 22, weight: .regular), .foregroundColor: UIColor.label])) } } else { self.configuration?.attributedTitle = AttributedString(key, attributes: AttributeContainer([.font: UIFont.systemFont(ofSize: 18, weight: .regular), .foregroundColor: UIColor.label])) } } else { let joined = keys.joined(separator: "") self.configuration?.attributedTitle = AttributedString(joined, attributes: AttributeContainer([.font: UIFont.systemFont(ofSize: 22, weight: .regular), .foregroundColor: UIColor.label])) } }

Hello, I am building a Content Filter app for iOS and would like to get access to some information about network connections that are happening on the device. I managed to have the handle(_ report: NEFilterReport) method of my NEFilterControlProvider called, but the bytesOutboundCount and bytesInboundCount properties of the report are always 0. How can I have the real byte count of the connection ?

I am making an iOS step counting app and I have included a widget in the design. I would like to get the widget to pull data from the main app to display step count etc so I created a bundle id for the widget and have been trying to use a group id to link them together. The group capabilities for both seem to be set up/enabled properly with the same App Groups id, but I've been getting an error in xcode which says, " 'Provisioning Profile: "BUNDLE_ID" doesn't include the com.apple.developer.security.application-groups entitlement.' Try Again But the identifiers do have the App Group id enabled. I have tried automatic signing, manual signing with generated profiles, unchecking and rechecking auto-signing, removing and re-adding the group capability. Creating a new bundle id from scratch, creating a new group id from scratch. Always I get the error. I've really pulled my hair out troubleshooting this and would appreciate support. I'm happy to answer and questions or share details. Thank you.

It seems to be that the functionality of the method setViewController:forColumn: in the column-style layout of a UISplitViewController has changed. iOS 18: setViewController:forColumn: pushes a new view controller onto the UINavigationController if it existed before the call. iOS 26: setViewController:forColumn: sets or replaces the view controller with a new view controller as a root of a new UINavigationController. My questions: what is the intended behavior? I did not find any documentation about a change. how do I replace in iOS 18 the old view controller with the new view controller passed to setViewController:forColumn:?

Hello everyone! I found a weird behavior with the animation of Menucomponent on iOS 26.1 When the menu disappear the animation is very glitchy You can find here a sample of code to reproduce it @available(iOS 26.0, *) struct MenuSample: View { var body: some View { GlassEffectContainer { HStack { Menu { Button("Action 1") {} Button("Action 2") {} Button("Delete", role: .destructive) {} } label: { Image(systemName: "ellipsis") .padding() } Button {} label: { Image(systemName: "xmark") .padding() } } .glassEffect(.clear.interactive()) } } } @available(iOS 26.0, *) #Preview { MenuSample() .preferredColorScheme(.dark) } I did two videos: iOS 26.0 iOS 26.1 Thanks for your help

My team recently released an app to the iOS app store. We are trying to add the Smart App Banner to our website to promote the app, but the banner is not shown. When the page loads, there is a flash of an empty Smart App Banner before it is automatically dismissed. This happens on every page load. If I put use an app ID of other apps the banner appears. I've triple checked that I'm using the correct app ID. So it seems like it is an issue with my app. I can see my app in the App Store, so I know it's available. I've tested on multiple phones.

Device: iPhone 17 Pro iOS Version: iOS 26.1 Camera: Ultra-wide (0.5x) using AVCaptureSession Our camera app freezes on iPhone 17 when switching frame rates (30fps ↔ 60fps). This works fine on iPhone 16 Pro and earlier. What We've Observed: Freeze happens on frame rate change - particularly when stabilization was enabled Thread.sleep is used - to allow camera hardware to settle before re-enabling stabilization Works on older iPhones - only iPhone 17 exhibits this behavior Console shows these errors before freeze: 17281 <<<< FigXPCUtilities >>>> signalled err=18446744073709534335 <<<< FigCaptureSourceRemote >>>> err=-17281 Is Thread.sleep on the main thread causing the freeze? Should all camera configuration be on a background queue? Is there something specific about iPhone 17 ultra-wide camera that requires different handling? Should we use session.beginConfiguration() / session.commitConfiguration() instead of direct device configuration? Is calling setFrameRate from a property's didSet (which runs synchronously) problematic? Are the FigCaptureSourceRemote errors (-17281) indicative of the problem, and what do they mean?

Hi everyone, I want users not to see the system context menu when long-pressing text on a page in Safari on iOS. I found on MDN that the CSS property -webkit-touch-callout: none; can achieve this. But in reality, it doesn't really work. MDN documents URL: https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Properties/-webkit-touch-callout Here’s a minimal example: function preventIOSSafariContextMenu() { if (document.getElementById(STYLE_ELEMENT_ID)) return; if (!IS_TOUCH_DEVICE) return; const style = document.createElement("style"); style.id = STYLE_ELEMENT_ID; style.textContent = ` html, body { -webkit-touch-callout: none !important; } `; (document.head || document.documentElement).appendChild(style); } The context menu persists. Has anyone else encountered this? Is this an intentional change in WebKit, or could it be a regression? If it’s intentional, is there a recommended alternative? Thanks in advance for any insights!

I am developing an IOS App that allow users to scan rooms, view the scans on device, and add notes. I need to preserve actual geometry (odd angles, chamfers, fixtures), not simplified RoomPlan boxes. Are there any easy ways to incorporate high quality texture mapping or PBR? Where is the documentation for scene reconstruction?

Up until some point relatively recently, I have been able to use Safari's web inspector to connect to the iOS simulator in order to debug our web application in development at http://localhost:8088. Now, the web inspector still OPENS, but it opens in a broken state. The context is available to select from Safari's "Develop" menu: Develop > "iPhone 16 Pro (Simulator)" > "localhost - login". It appears under the Safari heading if I have navigated to the web app in the browser, or under the Expo heading if I am accessing it through the webview in our React Native wrapper app. When I select it, the web inspector window does appear. However, once it opens, the Elements pane is empty, the Console pane is empty, expressions entered into the console are not evaluated, there's no content in Sources, Network, Storage, etc. Important notes: This broken state happens at http://localhost:8088 as well as http://127.0.0.1:8088, and it seems that the insecure context is the issue. The web inspector DOES work for HTTPS sites. If I navigate to, e.g., https://example.com in the simulator and connect the web inspector, everything works fine. The web inspector also works fine in Safari on macOS (OUTSIDE the simulator) when accessing non-HTTPS sites. It's only a problem for non-HTTPS sites when connecting to the simulator. A coworker has the same problem, so it is not isolated to my machine. I would enable TLS locally as a workaround, but this web app is very complex, and I know from experience that it is very difficult for various reasons to set it up properly for our project in development, and it will take significant non-trivial work to do so. So... Why is this happening? Is this expected behavior? Is there a way that I can debug my site on localhost without HTTPS?

The API we used: NSURL *url = [NSURL URLWithString:@"App-Prefs:INTERNET_TETHERING"]; The link provided by Apple engineer: https://developer.apple.com/forums/thread/761314 I did not find any URL in the link that leads to the secondary menu of system settings. Does this suggest that iOS 26 does not support this functionality? Moreover, is it possible that versions of iOS 18 and earlier may also not support this behavior in the future?

I’m building a React Native 0.72.10 iOS app and hitting build errors. Environment: macOS: Apple M4, Sequoia 15.7.2 Xcode: 26.1.1 React Native: 0.72.10 Errors: Could not delete /Users/.../ios/build because it was not created by the build system Unable to write file '/Users/.../ios/build/Pods.build/Debug-iphonesimulator/...': Operation not permitted (Multiple Pods / React Native framework headers affected) What I’ve tried: bash rm -rf ios/build rm -rf ~/Library/Developer/Xcode/DerivedData xattr -w com.apple.xcode.CreatedByBuildSystem true ios/build pod deintegrate && pod install sudo chown -R $(whoami) ios/build Observations: ios/build is recreated automatically. Some files have com.apple.xcode.CreatedByBuildSystem: true. 3.Xcode have Full disk access authorisation. Why does Xcode fail to delete / write to ios/build even though it’s recreated automatically by the build system? Is this caused by Xcode itself, macOS permissions? Any recommended fix or workaround for these “Operation not permitted” errors?

Does iOS 26 support HDR images for app icons to be rendered in High Dynamic Range for Springboard or not?

When will Apple mobile phones support some of the optional features of Bluetooth 5... specifically Extended Advertising and LE Coded PHY? There are many applications that benefit from having this capability in the mobile phone.
