Reply to HealthKit Background Health Data Collection, Emergency Contacts, and Automated Alerting Feasibility
An iOS app can't continuously run in the background. For more information about iOS background execution limits, see here. For using HealthKit in background, see here. (The latter is about HealthKit in watchOS, but the situation is pretty much the same in iOS.) Emergency Contacts is a user feature. For privacy reason, there is no API to access the information. Given that the answer to your question 1 and 2 is no, you can't achieve the automated alerting either. Best, —— Ziqiao Chen  Worldwide Developer Relations.

IOS Swift touch screen issue
MyOwnKeyboard Pad app has 4 text views with textfields that use touch screen for editing. There is one view, Compose, that has a textfield and a textview (UIRepresentable). The app enters text into the view using textfield buttons. The app has total control of editing. When entering text if the screen is touched it conflicts the cursor position and creates an out of bounds failure. In that view the app does not need any touch events. I need a method in UIRepresentable to disable the touch event. I am not familiar with UIRepresentable as this code was provided by Apple to solve a 16 bit unicode character issue. What would be the code to disable touch events in the UIRepresentable compose view. The app is free for a while until this problem is fixed. It is for iPads 11+ . The name in the app store is MyOwnKeyboard Pad. I know some great engineer will find the answer. DTS tried. Thanks to all, maybe I'll sell some. Charlie 25mar26

TESTFLIGHT: The requested app is not available or doesn t exist
Hello, I created an app using the latest version of Xcode (16.2), and I'm having a problem testing this app on my iPhones. I created this app just like all the others I've made for my clients, including one on (03/24/25), but when I went to upload another App to App Store Connect on (03/26/25) I couldn't test it on my phone. Points to consider: The app runs perfectly on the Emulator. All my terms and agreements with Apple are up to date. I tried to download the apps through Testflight on 2 different devices, iPhone 7 Plus (iOS 15.8.1) and iPhone 15 Pro Max (iOS 18.3.2), and I was unsuccessful in neither attempt. I can send my app to the internal testers, but when I click download, the following message appears: Could not install [APP NAME]. The requested App is not available or doesn't exist. I imagine this problem is with Apple itself, I have already contacted support, but I need to resolve this urgently for my customers. Has anyone experienced this and resolved it?

Apps cannot launch on iOS 9-12 devices after recent build - "The process failed to exec"
We found that our apps (and other apps from different companies) cannot launch on iOS 9 to iOS 12 devices. The app can be installed successfully but crashes immediately on launch. From the device syslog: assertiond: The process failed to exec SpringBoard: Bootstrapping failed - Unable to bootstrap process Our distribution certificate was issued on Feb 2, 2026, signed by WWDR G3 intermediate certificate.

Previews for SwiftUI views in Packages don't work in Xcode 26.4
I have an iOS project based on SwiftUI in which almost all code is organised in Packages. With Xcode 26.2 and 26.3, I can preview all SwiftUI views without issues. With Xcode 26.4, the same previews don't work, in the canvas appears this error message: Cannot preview in this file. Could not find target description for “TaskListView.swift”. The explanation is: The list of source files that produce object files did not contain this file to be previewed. Check to make sure it is not excluded using the EXCLUDED_SOURCE_FILE_NAMES build setting. If I add a SwiftUI view to the main project files (not in a package), the preview works as expected. Is it an Xcode 26.4 regression? Or do I need to modify some configuration file?

AccessoryTransport Extensions not launching on iOS 26.5 beta — missing entitlements not available in provisioning
Environment Xcode 26.5 beta iOS 26.5 beta Using AccessorySetupKit + AccessoryTransportExtension framework Three extensions: AccessoryTransportAppExtension, AccessoryTransportSecurityExtension, AccessoryDataProviderExtension Background Everything worked correctly on iOS 26.4 beta. All three extensions shared the entitlement com.apple.developer.accessory-transport-extension, and the system launched them as expected. After upgrading to iOS 26.5 beta (both Xcode and device), the app compiles and runs, the accessory pairs and connects successfully (state = authorized, BLE connected, notification forwarding = allow), but none of the extensions are launched by the system.

ScrollView clipping nav title in iOS 26?
When using a ScrollView inside some sort of navigation (stack or split view), large navigation titles seem to get clipped to the width of the scroll content for some reason? Minimal example: struct ContentView: View { var body: some View { NavigationStack { ScrollView { Text(Scroll Content) } .navigationTitle(Navigation Title) } } } Results in: Is this a bug in the beta, or has something changed and now I’m doing things wrong?

Navigation Bar Title Hidden When Right Bar Button Title Is Long (iOS 26)
I’m developing an app that includes a navigation bar with a centered title and a single right bar button item. I’ve noticed that when both the navigation bar title and the right bar button item’s title are relatively long, the navigation bar title becomes hidden. This issue only occurs on iOS 26. When running the same code on iOS 18, the layout behaves as expected, with both elements visible. Has anyone else experienced this behavior on iOS 26? Is this a known layout change or a possible bug?

Reply to TKTokenDriverConfiguration becomes permanently unusable after ctkd process restart
[quote='882312022, dopey, /thread/820940?answerId=882312022#882312022, /profile/dopey'] We are actually seeing seeing this happen in practice. [/quote] OK.

It’s hard to say what’s going on without more logging, but the most likely cause is a memory pressure exit, and that’s very non-deterministic.

Ideally this would include a sysdiagnose log taken: On a device with extra CryptoTokenKit logging enabled (see below) Shortly after seeing the problem But that might be hard to get, so you should feel free to file a bug with only your ‘kill ctkd’ step as evidence.

test NEAppProxyProvider without MDM?
This discussion is for iOS/iPadOS. I've written an NEAppProxyProvider network extension. I'd like to test it. I thought that using the NETestAppMapping dictionary was a way to get there, but when I try to instantiate an NEAppProxyProviderManager to try to install stuff, the console tells me must be MDM managed and I get nowhere. So can someone tell me, can I at least test the idea without needing to first get MDM going? I'd like to know if how I'm approaching the core problem even makes sense. My custom application needs to stream video, via the SRT protocol, to some place like youtube or castr. The problem is that in the environment we are in (big convention centers), our devices are on a LAN, but the connection from the LAN out to the rest of the world just sucks. Surprisingly, cellular has better performance. So I am trying to do the perverse thing of forcing traffix that is NOT local to go out over cellular. And traffic that is completely local (i.e. talking to a purely local server/other devices
