I submitted a Feedback (FB17843422) on Monday evening after the keynote about Tahoe beta 1. At the time it still wasn't listed in the "What build does the issue occur on?" dropdown. I selected "I'm not sure" instead hoping I could update it later but as far as I can tell that isn't the case since "Add more information" only lets me add additional comments.
Is there some way for me to do that or is it even necessary?

Weirdness going on here. Our app is crashing on startup with iPad 7s running iOS 18.5. Before updating to iOS 18.5, it was working fine on iPad 7s. Even with iOS 18.5, it is working fine on every device we have tried including dozens of other iPads and iPhones. We have narrowed it down to the SquareReaderSDK. If we remove that SDK, it will launch and work without issues. But, many of our users need the SquareReaderSDK.
The crash happens at app load, before appDelegate didFinishLaunchingWithOptions. So we can't figure out any way to debug the issue. Is anyone else having a similar issue? Square thinks it is an Apple issue.

unable to find developer runtimes in this list https://developer.apple.com/download/all/?q=simulator%20runtime
also, can see it's not being published since iOS 18.2 release, any specific reasons for it? or is the download link changed here?
hey I accidentally deleted my info.plist with holds my app version and other critical things and I don't know how to get it back or how to recode it

It is gone from where I used to find it on Apple’s web site. Is it deprecated or no longer available?
Hi. I have an iPad 7th gen running iPadOS 14.8.1. For testing purposes, I want to upgrade it to the latest release of iPadOS 17, even though the device wants me to upgrade to iPadOS 18.5. Is there a way to upgrade it to iPadOS 17?
btw this would free-up a newer iPad running iPadOS 17 so I can install iPadOS 26 beta.
Thank you.

I would like to inquire about a concern related to the app review process. Specifically, I would like to understand if forcefully denying an application's execution on the iOS Simulator (for instance, by implementing a check in the code that prevents the app from running in a simulated environment) could negatively impact or delay the app’s approval during the App Store review process.
This measure is intended solely for security and integrity reasons during development and distribution. The app functions normally on real devices, and all other guidelines and requirements outlined by Apple are being strictly followed.
Could you please confirm whether such a restriction on the Simulator is acceptable, and if there are any best practices or recommendations from Apple regarding this?
Thank you for your support, and I look forward to your guidance.

I'm running macOS 15.5. I now have Xcode 26 and I'm testing my iOS app against iOS 26. I've encountered several UIKit / iOS 26 bugs I'd like to report. In Feedback Assistant I choose "Developer Technologies & SDKs". Eventually I get asked "What build does the issue occur on?". The list of choices is:
iOS 18.2 Seed 4
iOS 18.1.1
iOS 17.7.2
An earlier iOS build
I'm not sure
So how to I report this as an iOS 26 beta 1 issue?
In the beta of Icon Composer, I see macOS, iOS, and watchOS icons, but there is nothing about visionOS and tvOS. Those icons are particularly hard and it would be great if this app worked for developing icons for all Apple platforms.
I tried asking this in a WWDC group lab, but they didn't get to it and suggested posting to the forum.
I'm trying to download the iOS 26 restore image for my iPhone 14 Pro Max, which is my test device. However, when I attempted to install it directly via the over-the-air (OTA) update, the iPhone rebooted to the iOS 26 "Welcome" screen, but with no touch functionality—the screen was completely unresponsive.
I restored the device back to iOS 18.5 and tried the OTA update again, but once more, the touch screen stopped working upon completion.
Now, I am trying to download the iOS 26 restore image from the official developer page (https://developer.apple.com/download/#ios-restore-images-ipad-new) to install it manually using my Mac. However, I've run into a problem with the download links:
The link for the iPhone 14 Pro Max (iOS 26) restore image actually downloads the iPhone 14 Pro (iOS 18.5) image.
Conversely, the link for the iPhone 14 Pro seems to provide the correct iPhone 14 Pro Max (iOS 26) image.
The issue is that when I try to restore my iPhone using this seemingly correct file, I receive an error that the firmware file is not valid or compatible. I suspect it's not being properly signed by Apple for my device during the restore process.
Does anyone have the correct, official download link for the iOS 26 restore image for the iPhone 14 Pro Max? How can I fix these errors?
In previous versions of the simulator, it was possible to import files into the Files app by dragging them from the Finder into the Simulator. It appears that in the iOS 26 Simulator, this opens the file in Safari.
I've only tried it with .json files so far.
The documentation at https://developer.apple.com/documentation/xcode/sharing-data-with-simulator says that the original behaviour should happen:
To add files to Simulator, select one or more files in Finder on your Mac, then click the Share button. Select Simulator from the share destination list. Choose the simulated device from the drop-down list. Simulator opens the Files app, and lets you select where to save the files.
I'd love to learn if this is intentional behaviour, and if so, what workarounds there might be. I use this pattern quite a lot, as I have a HealthKit app, and I've built a system that allows me to export workouts as JSON files from a real device, that I can then import into a simulator for testing.
Edit: I found a workaround. Make a folder in Files.app, then search for it within ~/Library/Developer/CoreSimulator/Devices. Open the folder in Finder, then add any files you want to be available in the Simulator.

For the Linux version of my application which is written in C++ using Qt, I display the CHM format help files with this code:
QString helpFile{ QCoreApplication::applicationDirPath() + "/Help/" + tr("DeepSkyStacker Help.chm","IDS_HELPFILE") };
QString program{ "kchmviewer" };
QStringList arguments{ "-token", "com.github.deepskystacker", helpFile };
helpProcess->startDetached(program, arguments);
(helpProcess is a pointer to a QProcess object)
The -token com.github.deepskystackerpart of that ensures that only a single instance of the viewer is used for any code that uses that invocation.
Are there any chm file viewers for macOS that are capable of that sort of trick? The ones I've found on the App Store give minimal information and appear to be very simple minded tools that are not not intended for integration into an application as above.
I know that MacPorts offers ports of kchmviewer but I'd prefer not to use either that or HomeBrew ...

Hi all,
I'm trying to add Spotlight support to a macOS app that handles custom virtual machine bundles with the .vpvm extension. I’ve followed the current documentation and used the modern CSImportExtension approach with a Spotlight Importer extension target.
Here’s what I’ve done:
App Info.plist:
Declared com.makeprog.vpvm as a UTI conforming to com.apple.package.
Registered it under UTExportedTypeDeclarations and CFBundleDocumentTypes.
Spotlight Importer Extension:
Added a new macOS target using the Spotlight Import Extension template.
Set the NSExtensionPointIdentifier to com.apple.spotlight.import.
Used CSSupportedContentTypes = com.makeprog.vpvm.
Implemented a minimal update(_ attributes:forFileAt:) method that sets displayName, title, and contentDescription.
Other steps:
Verified that the .appex is embedded under Contents/PlugIns/.
Confirmed it appears in mdimport -e output with correct UTI.
Used mdimport -m -d2 -t /path/to/file.vpvm, but I still get:
Imported '/path/to/file.vpvm' of type 'com.makeprog.vpvm' with no plugIn.
The extension is never invoked. I’ve also tried:
Ensuring the .vpvm file is a valid directory bundle.
Restarting Spotlight / rebuilding index.
Ensuring the app and extension are properly signed.
Tried installing the app in test virtual machine
Question:
Has anyone successfully used CSImportExtension for custom UTIs?
Is there something additional I need to do for the extension to be recognized and triggered?
Any advice or examples would be greatly appreciated!
Thanks in advance.
Up to now I've been building my x64 binaries on Sequioa specifying a target macOS level of 13.4. That worked fine.
In an attempt to debug a problem that was causing some pain I created a 13.4 x64 build environment and tried to build the code there.
This code:
using CacheKeyType = std::filesystem::path;
using CacheValueType = std::tuple<LoadedImage, int, bool>; // <image, lastUse, currentlyLoading>
using CacheType = std::unordered_map<CacheKeyType, CacheValueType>;
friend class ThreadLoader;
static inline constexpr int16_t MAXIMAGESINCACHE = 20;
static inline constinit std::atomic_int age{ 0 };
static inline std::shared_mutex rwMutex{};
static inline CacheType imageCache{};
got me the following errors:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.3.sdk/usr/include/c++/v1/__hash_table:838:5: error: static_assert failed due to requirement 'integral_constant<bool, false>::value' "the specified hash does not meet the Hash requirements"

2 errors generated.
Which isn't "mega-helpful" :(
I thought that specifying:
set(CMAKE_OSX_DEPLOYMENT_TARGET 13.4 CACHE STRING "Minimum operating system version for deployment" FORCE)
would have made the compilations use the same headers as for Ventura above, but it seems not?
Is this to be expected?

We're facing critical stability issues with a Xamarin-based iOS warehouse management app and need expert validation of our crash log analysis.
We’re seeing recurring issues related to:
Auto Layout Threading Violations
Memory Pressure Terminations
CPU Resource Usage Violations
These are causing app crashes and performance degradation in production. We've attached representative crash logs to this post.
Technical Validation Questions:
Do the crash logs point to app-level defects (e.g., threading/memory management), or could user behavior be a contributing factor?
Is ~1.8GB memory usage acceptable for enterprise apps on iOS, or does it breach platform best practices?
Do the threading violations suggest a fundamental architectural or concurrency design flaw in the codebase?
Would you classify these as enterprise-grade stability concerns requiring immediate architectural refactoring?
Do the memory logs indicate potential leaks, or are the spikes consistent with expected usage patterns under load?
Could resolving the threading violation eliminate or reduce the memory and CPU issues (i.e., a cascading failure)?
Are these issues rooted in Xamarin framework limitations, or do they point more toward app-specific implementation problems?
Documentation & UX Questions:
What Apple-recommended solutions exist for these specific issues? (e.g., memory management, thread safety, layout handling)
From your experience, how would these issues manifest for users? (e.g., crashes, slow performance, logout events, unresponsive UI, etc.

Any insights, analysis, or references would be incredibly helpful.
Thanks in advance!

Hello,
I've encountered unexpected behavior related to version information in our app logs, and I'd like to ask for some advice.
We reviewed logs collected from a user running our app (currently available on the App Store). The logs are designed to include both the build number and the app version.
Based on the build number in the logs, we believe the installed app version on the user's device is 1.0.3.
However, the app version recorded in the logs is 1.1.5, which is the latest version currently available on the App Store.
In our project, we set the app version using the MARKETING_VERSION environment variable.
This value is configured via XcodeGen, and we define it in a YAML file.
Under normal circumstances, the value defined in the YAML file (MARKETING_VERSION = 1.0.3) should be embedded in the app and reflected in the logs. But in this case, the version from the current App Store release (1.1.5) appears instead, which was unexpected.
We'd like to know what might cause this behavior, and if there are any known factors that could lead to this.
Also, is it possible that MARKETING_VERSION might somehow dynamically reflect the version currently available on the App Store?
