LLDB crash

Since installing the latest Xcode Beta (version 26.0 beta 4 17A5285i), it no longer runs my app on iPhone 11 and also not on iPad 10.2, both running iOS 18.5. The following code in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions ... // Preload both Tabbar Views NSArray* tabViewControllers = _tabBarController.viewControllers; _firstViewCntrl = (FirstViewController *)[tabViewControllers objectAtIndex:0]; _secndViewCntrl = (SecondViewController *)[tabViewControllers objectAtIndex:1]; UIView *dummy1 __unused; UIView *dummy2 __unused; dummy2 = _secndViewCntrl.view; // Triggers viewDidLoad <<<<< CRASH will crash the app (the problem is with the 'view' attribute): *** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView because no class named TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisu

Hello there :) We have an iOS/iPadOS app that uses the ImageCaptureCore framework for PTP communication with cameras. In general, it is working just fine. But in Xcode > Organizer > ’our app’ > Crashes we get a good amount of different – yet similar – crashes in this framework. So we can just observe that a good amount of end-users get those crashes. But we are not able to reproduce them ourselves... I've checked the stack traces of the other threads but nothing suspicious got my attention. Any good idea of how to address these crashes shown below? Happens on iOS 15–17. Thanks!

Hey, I've updated to both Xcode 26 Beta 4 and MacOS 26 Beta 4. Both run super stable so far. However, every time I use Xcode Previews for a few minutes, the entire system freezes for a few seconds and then crashes and reboots. I'm trying to generate a system diagnosis (which it offers me after the reboot), but it seems to be stuck generating. It's hard to say what exactly causes the crash, unfortunately. But it happened multiple times after starting to use Xcode Previews. Anyone else has that problem? I've also filed a feedback for this: FB19013059 Cheers Dennis

Something has changed in iOS 26 and now if custom scheme is used and web page contains scripts WebKit is terminated. 0x1130bc170 - [PID=47858] WebProcessProxy::didClose: (web process 0 crash) 0x1130bc170 - [PID=47858] WebProcessProxy::processDidTerminateOrFailedToLaunch: reason=Crash final class CustomSchemeViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let sampleConfiguration = WKWebViewConfiguration() sampleConfiguration.setURLSchemeHandler( SampleURLSchemeHandler(), forURLScheme: sample ) let webView = WKWebView(frame: view.bounds, configuration: sampleConfiguration) webView.autoresizingMask = [.flexibleWidth, .flexibleHeight] view.addSubview(webView) webView.navigationDelegate = self webView.load(URLRequest(url: URL(string: sample://pages/sample.html)!)) } } extension CustomSchemeViewController: WKNavigationDelegate { func webViewWebContentProcessDidTerminate(_ webView: WKWebView) { print(webViewWebContentProcessDidTerminate) } } final class SampleUR

I am writing to report a critical issue with the Xcode Organizer. It is failing to download App Version Information from App Store Connect, which prevents our team from accessing vital performance reports like disk writes, hangs, and launches. Other features such as Crashes, Metric's items work fine. When I open the Reports tab in the Xcode Organizer, it consistently shows the following error: Xcode failed to load builds for {Service}. {Account} failed with error: No Versions. [Important Context] What is particularly concerning is that this functionality used to work correctly. We were able to see build versions and access their reports up until a certain build in the past. However, at some point, this stopped working, and now no versions are loaded. Given that I am an Admin and this feature was previously working, the issue does not appear to be a simple permissions problem. It seems a change has occurred, either on the server-side or in how Xcode interacts with our app's record on App Store Connect

I have an issue with Xcode that it crashes my Macbook and restarts it instantly when I unpause the preview canvas. I managed to make it run for a minute longer by not watching a youtube video. I am writing a very simple SwiftUI project for iOS nothing too big to warrant any issues. Does anyone have a solution to fix this?

When I build my app for iPad OS, either 26, or 18.5, as well as iOS on 16.5 from Xcode 26 with UIDesignRequiresCompatibility enabled my app is crashing as it loads the main UIViewController, a subclassed UITabBarController which is being loaded programatically from a Storyboard from another SplashScreen ViewController. On i(Pad)OS 18.5 I get this error: Thread 1: Could not instantiate class named _TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView_ because no class named _TtGC5UIKit17UICoreHostingViewVCS_21ToolbarVisualProvider8RootView_ was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target) On iPadOS 26 I get this error: UIKitCore/UICoreHostingView.swift:54: Fatal error: init(coder:) has not been implemented There is no issue building from Xcode 16.4, regardless of targeted i(Pad)OS.

I built a SwiftData App that relies on CloudKit to synchronize data across devices. That means all model relationships must be expressed as Optional. That’s fine, but there is a limitation in using Optional’s in SwiftData SortDescriptors (Crashes App) That means I can’t apply a SortDescriptor to ModelA using some property value in ModelB (even if ModelB must exist) I tried using a computed property in ModelA that referred to the property in ModelB, BUT THIS DOESN”T WORK EITHER! Am I stuck storing redundant data In ModelA just to sort ModelA as I would like???

I can't use Xcode without it crashing. Just writing a very simple iOS app with SwiftUI (using only forms and sections). Whenever my canvas updates to correspond to my changes it forces my Macbook to restart. Does anyone have a solution for this. I'll be honest it's becoming really frustrating. Thank you.
