I am experiencing a critical issue with WKWebView navigation in iOS 18.2 beta, specifically regarding the function webView.loadFileURL(_:allowingReadAccessTo:). In previous versions of iOS, this function works as expected when loading valid file URLs from the app’s local directory (e.g., Application Support). However, in iOS 18.2 beta, the function fails to complete the navigation, producing a provisional navigation failure with WebKitErrorDomain, code 102 (Frame load interrupted). This issue severely impacts our app’s ability to load essential local resources, breaking core functionality. Here’s a summary of the troubleshooting steps and findings: File and Directory Verification: The url provided to loadFileURL is valid. Both the file path and parent directory exist within the app’s sandbox, and the directory is accessible. Configuration: The code specifies the parent directory in the allowingReadAccessTo parameter to meet sandboxing requirements, which works on iOS 18.1 and prior releases. Testing on Stable iOS Versions: The issue is exclusive to iOS 18.2 beta; testing on earlier stable iOS releases confirms that the function works as intended. Impact: This regression severely disrupts the app’s navigation and content loading, effectively blocking access to local resources required for the WKWebView to display content properly. The error log returned in the console is as follows: > Error Domain=WebKitErrorDomain Code=102 "Frame load interrupted" UserInfo={_WKRecoveryAttempterErrorKey=<WKReloadFrameErrorRecoveryAttempter: 0x303dd67e0>, NSErrorFailingURLStringKey=file:///var/mobile/Containers/Data/Application/4D128818-7E51-460E-B5D4-D2D70363EFA0/Library/, NSErrorFailingURLKey=file:///var/mobile/Containers/Data/Application/4D128818-7E51-460E-B5D4-D2D70363EFA0/Library/, NSLocalizedDescription=Frame load interrupted} We suspect this may be due to a change in WebKit permissions in iOS 18.2 beta that affects local file handling within WKWebView. Given that the our app relies heavily on these resources, we kindly request this issue be addressed promptly. If any additional information or sample code is required, please let us know, and we will gladly provide further details to assist in resolving this issue. Thank you for your attention and support. Best regards, Isabela

Hello, We're developing an SDK for iOS and need clarification on Apple's policies regarding the use of JavaScriptCore. Specifically, we want to understand if it's permissible to execute JavaScript code provided by our customers using JavaScriptCore. Our use case is as follows: Our customers will supply JavaScript code snippets, which our SDK will receive as text. The intention is to run these code snippets via JavaScriptCore to present interactive guides or dynamic content to the end-users of the app. Would executing customer-provided JavaScript code in this manner be considered a violation of Apple's App Store guidelines?

在使用xcode15.2与iOS14.2版本的手机进行调试时，发现OC编译的sdk无法正常传输数据给swift编写的项目。当我的手机连接xcode调试的时候，数据能够正常传输、转换。当我断开手机与xcode的连接的时候，就无法正常获取数据了。而这个问题目前我只发现在iOS14.2中。当我使用iOS17与iOS18手机调试时没有出现这个问题。请问有没有人遇到过相似的问题。

Hello, Is anyone experiencing devices on OS 17 disconnecting from Xcode 15 and 16 Beta? I remember there were a lot of past conversations around the time when iOS 17 released but it seems to still be happening even after using Xcode 16 beta. Re-pairing devices and rebooting the hosts appear to fix it temporarily. I discovered that killing the remoted process also allows xcode to reconnect to the devices. Using Xcode 16's devicectl also doesn't work. I have my devices connected to a USB Hub and to multiple devices. The odd thing is I have iOS 16 devices connected and those don't disconnect. I believe iOS 17 introduced a new coredevice stack to connect but has anyone found a fix for it or have any recommendations? TN3158 isn't relevant in my situation because VPN and Packet filtering is not in use and I filed feedback with Apple but they have't responded in a long time.

I have a iPhone 14 Pro Max device with iOS 18.2.1 but I am facing an in which the device gets restart abruptly.Interestingly, today the device is not restarting at all. I attempted a hard reset by pressing the volume up button, followed by the volume down button, and then holding the power button, but this method was unsuccessful. When I connect the device to a charger, the Apple logo appears, but it disappears after a short period, and the device does not progress beyond this point. I would appreciate any assistance in recovering my device.Has anyone experienced the same issue with the iPhone 14 series?

I writing swift code to change the app icon using setAlternateIconName and flutter MethodChannel to invoke swift. UIApplication.shared.setAlternateIconName(iconName) { error in if let error = error { print("Error setting alternate icon: \(error.localizedDescription)") result(FlutterError(code: "ICON_CHANGE_ERROR", message: error.localizedDescription, details: nil)) // Send error back to Flutter } else { print("App icon changed successfully!") result(nil) // Success! } } But I got an error message the requested operation couldn't be completed because the feature is not supported when using it on iOS 17+. So, Is setAlternateIconName still available? PS. In XCode, the code hinting shows that setAlternateIconName is still not deprecated.

Does iOS provide a callback when a notification is manually removed from the notification tray ?

Hello, After deploying our app, we encountered an issue where the app fails to launch properly on certain devices. To rule out potential code issues, we created a new clean project and tested it with the basic setup (certificate, bundle ID, and team). The app installs and runs fine on most devices, but it fails to open immediately on specific models. (The affected model is listed below.) Version: iOS 18.3.1 Model: iPhone 14 Pro After reviewing the console logs, we found an issue related to the app launching process. Could this issue be related to the app's configuration or the provisioning profile? We would appreciate any insight into why this issue occurs only on certain devices. Thank you for your help!

Hi, I'm working on a game for the past few years using first Unreal Engine 4, and now Unreal Engine 5.4.4. I'm experiencingan unusual crash on startup on some devices . The crash is so fast that I'm barely able to see the launching screen sometimes because the app closes itself before that. I got a EXC_CRASH (SIGABRT) so I know that it's a null pointer reference, but I can't quite wrap my head about the cause, I think that's something messed up in the packaging of the app, but here is where I'm blocked, I'm not that accustomed with apple devices. If someone has some advise to give, please, any help will be very valuable. Many thanks. Log : Crash Log on Ipad

We’re developing an iPad application that visualizes 2D and 3D building floor plans, including a mesh network of nodes that control lighting and climate. The node count ranges from 1,000 to 15,000. We’re using SceneKit to dynamically render the floor plan and node mesh on an iPad 10th generation running iPadOS 18.3. While the core visualization works, we are experiencing significant performance degradation as the node count increases. Specifically: At 750–1,000 nodes, UI responsiveness noticeably declines. At 2,000 nodes, navigating the floor plan becomes nearly unusable. We attempted to optimize performance with a Geometric Pool algorithm, but the impact was minimal. Strangely, the same iPad handles 30,000+ 3D objects effortlessly when using Unity or Unreal Engine, raising the question of whether SceneKit may not be optimized for this scale. Our questions: Is SceneKit suitable for visualizing such large node counts, or are we hitting an inherent limitation of the framework? Are there best practices or optimization techniques for SceneKit that we might be missing? Should we consider a hybrid approach or fully transition to a different 3D engine for this use case? We’ve attached a code sample below demonstrating the issue. Any insights, suggestions, or experiences would be greatly appreciated! ContentView.swift

Recently we started facing BLE disconnect issues between our BLE peripheral (microphone) and iOS app that we're having trouble solving. iOS App: Ionic Capacitor using @capacitor-community/bluetooth-le Microphone Peripheral: esp32 board using ESP-IDF Apache NimBLE stack App use case: Our app records a sound clip using the BLE microphone and sends data via a characteristic. The sound clip is broken up into several packets and all sent over ( over 1600 packets ). The microphone has an antenna and boosted signal as well. The Issue: Recently, we've been facing consistent disconnects between the microphone and the iOS app that we think we've narrowed down to the iOS device is disconnecting due to too many dropped packets. It seems the phone can't get further than roughly 10 feet before we see packet loss. Up until recently we had little to no range issues with transferring data and settings disconnected from the microphone while being much further away. Nothing has changed on our end on either the app or microphone firmware side. We use the same microphone firmware and app on Android and have no issues with range or dropped packets. It also seems like we can transfer a couple recording , like 2 or 3 ( each with its own connection i.e scan and connect , subscribe to characteristic and gather all the packets , do some processing then disconnect and start over ), without issue than every attempt at gathering the packets starts failing because of disconnects. Does anyone have any idea what might be going on? Do we need to fix our connection parameters? This seems to be mostly an issue since the newest iOS updates ( 18.3,18.3.1 ) however we've tested on previous versions and are now seeing same ble range issues. Any help or guidance on tracking down what's going on is appreciated.

Hello! I have a destination navigation which is TabVIew where each tab item is ScrollView. And when scrolling content of any of tab items is underneath navigation bar its background is always hidden. But at the same time tab bar background is toggled depending on scrolling content position. I expected it would work with TabView the same as with any other view. Is it supposed to work like that?

I'm using the iOS simulator with a StoreKit configuration file. I can see that there have been transactions while the app has been closed, but my StoreKit 2 listener is never called with those updates to be able to finish them When I open my app from a cold start. I've added a listener on application(_:didFinishLaunching:launchOptions:) like this: func startObservingTransactions() { task = Task(priority: .background) { for await result in Transaction.updates { if case .verified(let transaction) = result { await transaction.finish() } } } } But the Transaction.updates loop never gets called (have added breakpoints to check). It's only ever called when a purchase is made, or subsequent transaction renewals when the app is open. Only then it will get the previously unfinished transactions. Steps to reproduce: Create an app with a StoreKit config file (with sped up transactions) to purchase an item Make a purchase then quit the app Wait for a bit for more transactions to be made while the app is closed. Open the app from a cold start and none of the transactions will be finished by the listener in your app. Cancel the subscription via the transaction manager. Close and open the app from a cold start. The first transaction will be finished by the listener but none of the others will be. In Apple's docs it says If your app has unfinished transactions, the listener receives them immediately after the app launches Why is this not the case?

Hello, why is apple won’t adding Just-In-Time compiler to ”Emulators” in the app store. And/or hypervisor for newer devices. i feel like UTM (which is a PC Emulator) or other Apps that emulate need JIT to work properly, and will consume significantly less battery to emulate/virtualize, And will have a noticeably better performance than just not enabling JIT, and by the way jit is already being used on iPadOS/iOS 18.3/18.3.1 and newer/older version of that so being enabled by the choice of the developer of the App is more convenient than doing it with tools. and by the why apple wont let emulators on iPads and newer iPhones do hypervisor, it’s better than JIT but requires a good cpu, like making it available to people with newer/powerful devices, hypervisor is better than JIT by a lot and removing it in iPadOS/iOS 18.4 was an unnecessary choice?, becuase it had a better potential in virtualization instead of emulating, and I feel like enabling it In M1-M2 iPads and A14-18pro and newer devices is just better from having it disabled, to unlock the fullest potential of the iPad it needs to have a app or something to do instead of just running high graphics games/or Apps.

I'm calling a method with the context as parameter, within the context's perform block – is this really not legal in Swift 6? actor MyActor { func bar(context: NSManagedObjectContext) { /* some code */ } func foo(context: NSManagedObjectContext) { context.performAndWait { self.bar(context: context) // WARN: Sending 'context' risks causing data races; this is an error in the Swift 6 language mode // 'self'-isolated 'context' is captured by a actor-isolated closure. actor-isolated uses in closure may race against later nonisolated uses // Access can happen concurrently } } } The warning appears when I call a method with a context parameter, within the performAndWait-block. Background: In my app I have methods that takes in API data, and I need to call the same methods from multiple places with the same context to store it, and I do not want to copy paste the code and have hundreds of lines of duplicate code. Is there a well-known "this is how you should do it" for situations like this? This is related to a previous post I made, but it's a bit flimsy and got no response: https://developer.apple.com/forums/thread/770605

I have a UITextField with UITextContentType equal to oneTimeCode. It works as expected if the message is in English and the keyword "OTP" exists. It doesn't work if the message is in Greek and the keyword "OTP" is translated also in greek. Is the OTP keyword really needed? Is there any alternative? Which are the keywords for any case? Are these keywords only in English? Thanks in advance!

I'm creating an app which gamifies Screen Time reduction. I'm running into an issue with apples Screen Time setting where the user can disable my apps "Screen Time access" and get around losing the game. Is there a way to detect when this setting is disabled for my app? I've tried using AuthorizationCenter.shared.authorizationStatus but this didn't do the trick. Does anyone have an ideas?

I'd like to set up a communication mechanism between the Ui test runner and my iOS app. The purpose is to be able to collect some custom performance metrics in addition to standard ones like scrollingAndDecelerationMetric. Let's say we measure some specific intervals in our code using signposts, then serialize the result into a structured payload and report it back to the runner. So, are there any good options for that kind of IPC? The primary concern is running on Simulator. However, since it is not a regular UI test but more a performance UI test, and it is usually recommended to run those on a real device, with release optimizations/flags in place, I wonder if it is feasible to have it for device too.

I have a visionOS app that I’m adding support for IOS and will like to keep using RealityView. I know there are the following modifiers to add some navigation .realityViewCameraControls(.orbit) .realityViewCameraControls(.dolly) .realityViewCameraControls(.pan) But how can I add more than one? For example I would like to orbit with one finger, Pan with 2 fingers and dolly by pinching. Is this possible and if so can someone share some sample code on how to achieve that? Thanks, Guillermo
