“Visual Studio Maui IOS”

Hello dear Apple Platform Engineers, I'm working on an iOS App that connects to a Bluetooth Low Energy Peripheral in the foreground. Whenever the App moves into Background, we want to continue syncing data & therefore implemented State Restoration to be informed about Discovery, Connect, Disconnect or Characteristic changes in the Background in order to wake the App up whenever it was Terminated due to memory issue. I consulted https://developer.apple.com/library/archive/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/CoreBluetoothBackgroundProcessingForIOSApps/PerformingTasksWhileYourAppIsInTheBackground.html#//apple_ref/doc/uid/TP40013257-CH7-SW1 for this & assigned: CBCentralManagerOptionRestoreIdentifierKey Reinstantiate the dedicated CentralManager & implemented the centralManager(_ central: CBCentralManager, willRestoreState dict: [String : Any]) Delegate Additionally, I assigned the following keys on connect(_ peripheral: CBPeripheral, options: [String : Any]?

Hello All, I have a app which has a WKWebview loading some code from a remote origin - https://my-company.example.com When WKWebview loads remote origin, that page does load some of the sub-resources from in-app localhost server (GCDWebserver), i.e. reach out to a loopback based in-app GCDWebserver, now to provide a secure context I had an existing setup with self signed cert, CORS and everything needed for https on localhost. And the sub-resources used to load fine from https localhost till 26.4 Starting with iOS 26.4 it started breaking with TLSv1_ALERT_UNKNOWN_CA Is there any known guidance for this? Technically as per w3c spec, localhost is considered secure context by default right? and no special things need to be done. But ios/Webkit seem to be different in this regard. Is this a known issue, and is there any mitigation here? I'll try to provide a sample app soon if possible.

After updating to Xcode 26.4 and also the update on the simulator the copy paste feature in the simulators doesn't work anymore and i can't build my app without it because the user has to copy and paste api keys in it. Is there an solution for it I have tried to install an other simulator ios version but then the simulator doesn't work on the the new xcode. Have someone already found an solution?

Hi everyone, I have a SwiftUI app using CKQuerySubscription on the public database for social notifications (friend requests, recommendations, etc.). Push notifications work perfectly in the Development environment but never fire in Production (TestFlight). Setup: iOS 26.4, Xcode 26, Swift 6 Container: public database, CKQuerySubscription with .firesOnRecordCreation 5 subscriptions verified via CKDatabase.allSubscriptions() registerForRemoteNotifications() called unconditionally on every launch Valid APNS device token received in didRegisterForRemoteNotificationsWithDeviceToken Push Notifications + Background Modes (Remote notifications) capabilities enabled What works: All 5 subscriptions create successfully in Production Records are saved and queryable (in-app CloudKit fetches return them immediately) APNS production push works — tested via Xcode Push Notifications Console with the same device token, notification appeared instantly Everything works perfectly in the Development environment (subscrip

I have a few feasibility questions regarding health data processing on iOS, related to HealthKit and system capabilities: Background Health Data Collection Can an iOS app continuously collect and process health data in the background, including: Collecting health data from the Health app while the device is locked or in sleep mode Triggering user notifications when anomalies are detected in health data processing Are there any technical limitations? Do these capabilities require specific enterprise qualifications or additional fees? 2. Emergency Contacts Integration Can an app write or modify the system’s built-in Emergency Contacts (Medical ID)? If a user updates Emergency Contacts in iOS Settings, can the app receive a change notification or access the updated data? 3. Automated Alerting for Health Metrics Beyond Apple’s fall detection, can abnormal health metrics (heart rate, irregular rhythm, blood oxygen, etc.) trigger automated alerts such as SMS to preset emergency contacts—w

Summary: After upgrading to Xcode 26.4, app-hosted XCTest execution on physical devices running iOS 16 fails at test-planning time with Logic Testing Unavailable. The same project and same device work under Xcode 26.2. The failure reproduces with a standalone minimal Xcode project, which suggests this is an Xcode regression rather than a project-configuration issue. Environment: Xcode: 26.4 (17E192) macOS: Tahoe 26.4 Failing device: iPhone 11 (iPhone12,1), iOS 16.0.3 Working comparisons: Xcode 26.2 + same iPhone 11 (iOS 16.0.3): works Xcode 26.4 + iPad Pro 11-inch (4th generation) on iOS 26.3: works Regression: Yes. Works on Xcode 26.2. Fails on Xcode 26.4. Same project, same signing setup, same physical iOS 16 device. Minimal reproduction: A minimal sample project with: one iOS app target one app-hosted unit-test target one UI-test target (for comparison; not required to reproduce) Steps for the unit-test repro on a physical device running iOS 16

I recently released version 8.5.4 (build 188) using Cloud Build. During testing via TestFlight, the app worked correctly on an iPhone 6 running iOS 12.5.8. However, after the app was published on the App Store, I found that the same version does not open at all on iOS 12 devices. Previously, earlier versions (such as 8.5.3) were functioning properly on iOS 12. My app’s minimum deployment target is set to iOS 12.0. This issue appears only with the App Store version, while the TestFlight version works fine on the same device. Due to this, I have paused the phased release of version 8.5.4 to prevent further impact on users still running iOS 12. I would like guidance on the following: 1. Has there been any recent change or limitation affecting apps targeting iOS 12 on the App Store? 2. Is there a way to prevent iOS 12 users from downloading version 8.5.4 while allowing them to continue using version 8.5.3? 3. Is there any recommended approach to ensur

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

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?

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. This issue affects all apps under our Apple Developer account on iOS 9-12 devices. iOS 13 and above works fine.
