LLDB crash

Dear Apple Team, We are reaching out regarding several compatibility issues our app users have encountered after upgrading to iOS 26. These issues not only affect our application but also seem to impact the system's native settings, which has raised concerns about the universality of these problems. Problem Description Bluetooth Functionality: When users attempt to use the Bluetooth feature within our app after upgrading to iOS 26, the app freezes completely. What's more, when accessing the Bluetooth section in the system Settings app, it also freezes and ultimately crashes. Location Service: The location service on the device becomes inoperable after the iOS 26 upgrade. However, both the Bluetooth and location service issues are resolved after the user restarts the device. 2. Questions Universality: We are eager to know if these issues are exclusive to our app or are a more widespread problem among other applications on iOS 26. Are these known compatibility glitches in iOS 26? Avoidance: Is there an

I have a simple app that makes an HTTPS call to gather some JSON which I then parse and add to my SwiftData database. The app then uses a simple @Query in a view to get the data into a list. on iOS 16 this works fine. No problems. But the same code on iOS 26 (targeting iOS 18.5) crashes after about 15 seconds of idle time after the list is populated. The error message is: Could not cast value of type '__NSCFNumber' (0x1f31ee568) to 'NSString' (0x1f31ec718). and occurs when trying to access ANY property of the list. I have a stripped down version of the app that shows the crash available. To replicate the issue: open the project in Xcode 26 target any iOS 26 device or simulator compile and run the project. after the list is displayed, wait about 15 seconds and the app crashes. It is also of note that if you try to run the app again, it will crash immediately, unless you delete the app from the device. Any help on this would be appreciated.

Hello,Our app has caught an issue with gesture recognizers. This problem only occurs on Mac OS 26.0. From the stack trace, it seems that this is not a problem on the app side, but an exception reported by AppKit. I have provided the stack trace, please help check it. stack info: NSInternalInconsistencyException: AppKit doesn't support comparing gesture recognizers across windows AppKit doesn't support comparing gesture recognizers across windows NSInternalInconsistencyException __exceptionPreprocess exception info: OS Version: macOS 26.0.0 Exception Type: NSInternalInconsistencyException: AppKit doesn't support comparing gesture recognizers across windows Crash Thread ID: 0 Application Specific Information: AppKit doesn't support comparing gesture recognizers across windows NSInternalInconsistencyException __exceptionPreprocess expanded stack: Crashed Thread:0 stack.package stack.filename stack.function stack.lineno stack.in_app CoreFoundation None __exceptionPreprocess None 0 libobjc.A.dyli

I have four apps currently deployed on the App Store. One of these apps crashes on launch when running on iOS 26, but functions as expected on iOS 18 and earlier versions. I am seeking to understand what changes in iOS 26 might be causing this issue. When running the app in debug mode on devices with iOS 26 using Xcode 16.1, the app crashes. The crash log references libobjc-trampolines.dylib, suggesting a potential issue with the Objective-C runtime. Has anyone else encountered a similar issue?

Steps to Reproduce: Connect a MacBook Pro (lid closed) to a large external monitor. Run the SDL3 testwm test application. git clone https://github.com/libsdl-org/SDL.git cmake -S . -B build -DBUILD_SHARED_LIBS=OFF -DSDL_TESTS=ON cmake --build build The testwm binary will be located in the build/test directory. Move the application window around the left edge of the external display. Observed Result: WindowServer crashes.
