My app crashes on startup in iOS 26
I have an app with a small but devoted following. It has not been upgraded since 2022 and has been working very well. On iOS 26 it crashes almost at startup. After hooking up to Xcode and running I get this message in the console: objc[64686]: Class PSSegment is implemented in both /System/Library/PrivateFrameworks/PolarisGraph.framework/PolarisGraph (0x291ed9f78) and /private/var/containers/Bundle/Application/08486FCF-548A-467C-8BA3-D722734463FC/HikeTracker.app/HikeTracker.debug.dylib (0x101d309e8). This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed. PSSegment is the name of an entity in my Core Data managed object model. If I refactor it to P_Segment the app starts. PolarisGraph means nothing to me. The PS stands for Persistent Store, but in this case it seems that PolarisGraph is PSing in my sandbox. How can this happen? I'll attach the longer message that comes with the crash. error messages.txt

iOS 26 + UINavigationBar crash in layoutSubViews - new observation tracking

It seemed related to the new view update with observation tracking: link to documentation Any lead on how I should investigate this? Many thanks in advance!!

Reply to Nasty problems in Xcode 26.2: Apple Intelligence crash & Source Code Control Failure
AN UPDATE: This suggestion (from ChatGPT) resolved the problem of the AI Assistant crashing: # from the folder that contains your .xcodeproj / .xcworkspace mv *.xcodeproj/xcuserdata ~/Desktop/xcuserdata_xcodeproj_backup 2>/dev/null mv *.xcworkspace/xcuserdata ~/Desktop/xcuserdata_xcworkspace_backup 2>/dev/null There still remains the problem where one specific .mm file will absolutely NOT show its specific changes. I'll continue to investigate.

Post-iOS update crash on app launch with split/black screen (Flutter + WebView)
Hi all. Thanks in advance for any guidance you’re able to offer. We’ve had an issue reported by multiple customers where, following an iOS update, our app crashes on the next launch. When this happens, users briefly see a split screen: half of the view shows the app background, while the other half is completely black. After this point, the app is unusable. Here’s what we’ve uncovered so far during our investigation: We believe this occurs when a user is already signed into the app at the time they install the iOS update. For context, we intentionally do not force users to log out of the app, as it’s primarily used for customer support and assistance. This is a firm business decision and not something we plan to change. We suspect the issue is related to our Flutter WebView and how it restores or reloads session state following an iOS update. In the past, updating the Flutter version has resolved similar issues, but we are currently on the latest available version. Once the half-screen issue occurs,

xCode 26.2 Debug exetubale ON crashes on ios 26.2 devices
Hi, I am running build on ios 26.2 device, connected with cable (not wifi) and it crashes because files are not loaded or something. But when i turn off Debug Exetuble, it works just fine. Also, tried to run on ios 18.2 device, with Debug executable On - everything is ok, and breakpoints work. My guess, App crashes on reading and loading Assets and others app files like certificates. XCode run logs shows: **Too many file errors. ** sample.txt xcode_run_logs.txt Also, exectued image list on lldb console, could not attach here, if needed i can add it with some url here.

Reply to Phone Crashing
Not enough information to help you. What phone are you using? What version of iOS did you install? When does the phone crash? And do you mean the actual phone crashes and reboots, or do you mean apps just crash immediately when you try to launch them? Why doesn't it send messages? What happens? Any errors? No one can help you unless you provide the right information. It's like walking up to a mechanic and telling him your car won't start, but not telling him what model of car it is, where it is, what you've tried to get it to start, and into which lake you threw the keys. Besides, this isn't the place for your query. These are the Developer Forums, where developers of apps for Apple's platforms ask each other for hints and tips on coding. Your question is more of a product support one, so I'd suggest you ask it over at the Apple Support Forums. Thanks.

Nasty problems in Xcode 26.2: Apple Intelligence crash & Source Code Control Failure
I know this post isn't going to give a lot of details, but what I experienced tonight was so completely weird that I wanted to get it posted here in case others run into it: FIRST: All was well until I made a trivial change to a large Objective-C++ module. I suddenly got the idea to look at that line in the code review pane, to see if that area of code had ever had recent modifications. But, the entire module showed up as modified -- one giant change bar, with nothing on the right side of the code review pane, no matter what commit I selected. Then I noticed that the two lines of code which had all of 4 characters edited were no longer showing any change bars. Yet, the file showed up as modified. Still, the exact line changes were not showing in the source code navigator, even though other files showed their changes. Note I'm connected to our remote repo on github. I did some command line git checks of the local repo, and the changes were there (as yet unstaged). So -- I figured, I'm gonna ask the Apple Codin

Reply to Keyframe animation crashes with +[_SwiftUILayerDelegate _screen]: unrecognized selector sent to class on iOS 26
We're experiencing a similar UpdateCycle crash on iOS 26, though with a slightly different manifestation. Our crash occurs when displaying custom inputView keyboards on iPad devices. Crash Details: Exception: NSInternalInconsistencyException Message: Invalid parameter not satisfying: parentEnvironment != nil Location: UC::DriverCore::continueProcessing() at address 5472 in UpdateCycle library OS Version: iPadOS 26.1.0 (84.6% of crashes), also seen on 26.0.0 and 26.0.1 Device: 100% iPad devices (iPad Pro models, all in landscape orientation) Reproduction Context: The crash occurs when a custom UIView is set as textField.inputView and the text field becomes first responder on iPad. The crash happens during UpdateCycle's processing when it attempts to access the focus environment hierarchy. The custom keyboard view appears to be accessed by UpdateCycle before it's fully integrated into the focus hierarchy, resulting in a nil parentEnvironment. Key Observation

Xcode Playgrounds crashes upon microphone access
Sorry if this is a dumb question. I’m still a beginner. I created an Xcode Playground app with Microphone and Speech Recognition capabilities enabled, along with a backup Info.plist. However, when running the app on Mac Catalyst, a real device, or the iOS and iPadOS simulators, it crashes right after the Speech Recognition permission popup and again after the Microphone permission popup. For extra context, the app initially worked fine in the Swift Playgrounds app, but that environment uses an outdated SDK, so it no longer supports some of the features I’ve implemented. I’m also struggling to find clear, beginner-friendly documentation that explains how AVAudioEngine works, which is making it hard to understand what’s going wrong and how to debug it.
