“LLDB crash”

I am facing a persistent issue with an Endpoint Security (ES) extension that is crashing only when processing the ES_EVENT_TYPE_AUTH_OPEN event. Other event types, including ES_EVENT_TYPE_NOTIFY_OPEN and ES_EVENT_TYPE_NOTIFY_MMAP, work without any problems. func startMonitoring() { guard !isMonitoring else { return } let result = es_new_client(&gClient) { (client, message) in guard message.pointee.action_type == ES_ACTION_TYPE_AUTH else { return } let pid = audit_token_to_pid(message.pointee.process.pointee.audit_token) if pid == gSelfPID { es_respond_flags_result(client, message, 0x7FFFFFFF, true) var token = message.pointee.process.pointee.audit_token es_mute_process(client, &token) return } guard message.pointee.event_type == ES_EVENT_TYPE_AUTH_OPEN else { es_respond_auth_result(client, message, ES_AUTH_RESULT_ALLOW, true) return } let pathData = message.pointee.event.open.file.pointee.path guard let pathPtr = pathData.data else { es_respond_flags_result(client, message, 0x7FFFFFFF, true)

.popover(isPresented: modifier doesn't work on Mac Catalyst when attached to the item in the toolbar. The app crashes on button click, when trying to present the popover. iOS 26 RC (macOS 26 RC) Feedback ID - FB20145491 import SwiftUI struct ContentView: View { @State private var isPresented: Bool = false var body: some View { NavigationStack { Text(Hello, world!) .toolbar { ToolbarItem(placement: .automatic) { Button(action: { self.isPresented.toggle() }) { Text(Toggle popover) } .popover(isPresented: $isPresented) { Text(Hello, world!) } } } } } } #Preview { ContentView() }

I'm working on a multi-process macOS application (based on Chromium/Electron) that uses Mach ports for inter-process communication between the main app and its helper processes. Background I have an MAS build working successfully via TestFlight for internal testing. However, public TestFlight testing requires Apple review, and while waiting for that review, I wanted to provide a directly distributable build for external testers. I attempted to create a Developer ID signed build with App Sandbox enabled, expecting it to behave similarly to the MAS build. The Problem With App Sandbox enabled (com.apple.security.app-sandbox) and identical entitlements, I observe different behavior depending on the signing certificate: Apple Distribution certificate: App launches successfully, mach-register and mach-lookup work Developer ID certificate: App crashes at launch, mach-register is denied by sandbox The Console shows this sandbox violation for the Developer ID build: Sandbox: MyApp(13605) deny(1) mach-register

We're seeing sporadic crashes on devices running iOS 18.1 - both beta and release builds (22B83). The stack trace is always identical, a snippet of it below. As you can tell from the trace, it's happening in places we embed SwiftUI into UIKit via UIHostingController. Anyone else seeing this? 4 libobjc.A.dylib 0xbe2c _objc_fatalv(unsigned long long, unsigned long long, char const*, char*) + 30 5 libobjc.A.dylib 0xb040 weak_register_no_lock + 396 6 libobjc.A.dylib 0xac50 objc_storeWeak + 472 7 libswiftCore.dylib 0x43ac34 swift_unknownObjectWeakAssign + 24 8 SwiftUI 0xeb74c8 _UIHostingView.base.getter + 160 9 SwiftUI 0x92124 _UIHostingView.layoutSubviews() + 112 10 SwiftUI 0x47860 @objc _UIHostingView.layoutSubviews() + 36

Hi, I am implementing a premium feature in my app where CloudKit syncing is available only for Pro users. The Workflow: Free Users: I initialize the ModelContainer with cloudKitDatabase: .none so their data stays local. Pro Upgrade: When a user purchases a subscription, I restart the container with cloudKitDatabase: .automatic to enable syncing. The Problem: If a user starts as Free (creates local data) and later upgrades to Pro, the app crashes immediately upon launch with the following error: Fatal error: Failed to create ModelContainer: SwiftDataError(_error: SwiftData.SwiftDataError._Error.loadIssueModelContainer, _explanation: nil) It seems that SwiftData fails to load the existing data once the configuration changes to expect a CloudKit-backed store. My Question: Is there a supported way to toggle CloudKit on for an existing local dataset without causing this crash? I want the user's existing local data to start syncing once they pay, but currently, it just crashes. My code: i

After upgrading to iOS 18, crashes caused by calling null function pointers have changed their crash signal from SIGEVG to SIGKILL, making it impossible for developers to capture crash stacks using third-party components like KSCrash/PLCrashReporter. Is this a design change in iOS 18's memory protection mechanism? If so, are there any officially recommended crash capture solutions? Crash example code: - (void)MockCrashOnNullFunctionPointer { void (*func)(void) = NULL; func(); } Crash report comparison:

The Test target not build for not such file or directory: 'CoreGraphics'. Not sure why I get this error, but I configured the target without forgetting the variables BUNDLE_LOADER with $(BUILT_PRODUCTS_DIR)/MyExistingApp.app/MyExistingApp value and TEST_HOST with $(BUNDLE_LOADER) value. App target (not the test target), the Symbols Hidden by Default build setting its equal to NO, unlike the Test target that is set to YES. Any variable more for this? I'm not sure if I should take anything into account when using Xcode 26.1.1 and Swift Testing framework.

Dear random Apple UIKit engineer. This is a question for you. Today let's speak about keyboard notifications. In particular, UIResponder.keyboardWillShowNotification and UIResponder.keyboardWillHideNotification. While working with those, I noticed some undocumented behaviour. First, let me give you some context: extension UIViewController { func registerForKeyboardNotifications() { NotificationCenter.default.addObserver(self, selector: #selector(keyboardNotification), name: UIResponder.keyboardWillShowNotification, object: nil) NotificationCenter.default.addObserver(self, selector: #selector(keyboardNotification), name: UIResponder.keyboardWillHideNotification, object: nil) } /// Override this method to handle keyboard notifications. @objc func keyboardNotification(_ notification: Notification) { ... } } Eventually, I found that latter method with 3 dots has an implicit animation inside it's scope. Here is the [proof.](https://medium.com /uptech-team/why-does-uiresponder-keyboard-notification-handler-animate-
