My app will not open to myself or to clients and has a pop up that claims "App Outdated" The app version you are using is no longer supported. Please install he latest Heartland update through the App Store. However, there have been no updates to the app.

Does anyone know where I can get to the API diffs for iOS 18 -> iOS 26?

Tech stack: React Native + Expo. We are using two solo developer accounts (not a business or team account). Context: Friend and I set out to make an app together. Friend created app and set it up on Apple. We worked on it together. He controlled devops (builds and submission). Friend no longer can commit to development. Wants to transfer to me. I create apple developer account. After app transfer, my phone (deviceid) underwent a 14 day soft ban preventing builds. That has since been lifted. There seems to be something in place preventing me from making dev builds on the original dev bundleid. It says it's still owned by him despite the app transfer. Bottom line: what needs to happen so 1 can make dev builds? nice to have: is there a way for us to both make dev builds under the same bundleid?

Is it recommended to turn off 'Charge Limit' if I leave my iPhone plugged into my Mac all day for development? I want to minimize battery degradation. Thanks

Hello, According to documentation, the App Store does not re-download the entire app when updating, but instead generates an update package containing only the changed content compared to the previous version. I’d like to clarify the following points: 1. Granularity of file changes If only part of a large file changes, does the update package include the entire file, or does it patch only the modified portions within that file? 2. Guideline on separating files The documentation recommends separating files that are likely to change from those that are not. How should this be interpreted in practice? 3. Verifying the diff result Is there a way for developers to check the actual diff result of the update package generated by the App Store without submitting the app? Is there a diff command tool or comparison method closer to the actual App Store update process? 4. Estimating update size during development For apps with large-scale resources, minimizing update size is critical. Are there any tools or best practices to estimate the size of the update package before submitting to the App Store? Any clarification or reference materials would be greatly appreciated. Thank you.

I want to create a dynamic library for my iOS project, which would be loaded at runtime. In Xcode, there are templates available for creating a static/dynamic lib for MacOS. But under the iOS tab, there is only a "static library" template. So, I used the "static library" template and in its build settings I changed the Mach-O type to "dynamic library". Now after building it, I use the file command on the generated file and it tells me it is a dynamic lib. But the generated file still has .a extension, which is usually for static libs. I'm aware we can tell Xcode in build settings to change the .a extension to something else, say .dylib but this seems like a hacky way to create a dynamic library. What is the correct way? I am aware that standalone dylibs are not supported on iOS, and we need to wrap them in a framework. For my use case, the framework will literally be a wrapper, it won't have any source files of its own. It should only contain the dynamic lib generated from some independent codebase. I am not sure how to place the dylib in the framework.

I am working on an iOS app and I want to achieve on demand module download inside the app when the user clicks on the module icon which he wants to use. The idea is that we have a super app consisting of multiple modules say four independent apps/features and I want to separate each one so that when the user selects a specific app/feature, it’s downloaded on demand and then opened directly within the same super app resulting in a lower app size initially I want to upload all the code of all modules to app store connect but when the user downloads the app, then only one module's code should be available to the user, the rest of the module's code should be downloaded when the user wants to use that module. I know apple restricts downloading new code but in my case I want to upload all the code to app store for review but just give option to the user to get rest of the code when needed. Any guidance, architectural advice, or example implementations would be highly appreciated.

Hello, Good morning to you all. Please I need a guide on how to change my app icon on the developer account. Necessary steps would be appreciated Thanks for the anticipated assistance. Best Regards Biggie

I am on a windows computer using visual studio 2026 for developing .NET Maui apps for Android and iOS. Am I able to connect my iPhone to my windows computer and deploy my .NET Maui app to my connected iPhone during deveoplemt?

In SF Symbols 7 (115), there are 458 symbols missing Availability info. I only discovered this after using one that didn’t appear in iOS 18 but does in iOS 26. Questions: Are there plans to add Availability info for all symbols? If the field is blank, is there a safe latest-OS version we can assume? I realize managing 7,000+ icons is tough, but missing info like this makes development frustrating. It doesn't help that there's no build warning when a named image isn't found, it just defaults to the text label. Screenshot Screenshot of SF Symbols 7 showing three symbols missing Availability info. The symbol ellipsis.circle.badge is selected and its properties pane also shows no Availability info.

There was a time that Apple Developer Documentation provides a filter to show the changes across versions, at https://developer.apple.com/documentation/technologies , with purple (modified), green (added), and red (deprecated) annotations. I wonder if this feature is completely removed, or is it still hiding somewhere? It is helpful to diff the API changes among versions. Thanks. edit: as pointed out by Rick, here is an archive link to what it used to look like

I observed the following problem: A scientific code to perform Reverse Monte Carlo simulations (‘rmcxas’) compiled with the most up to date version of gcc/gfortran and Xcode including command line tools on Mac OS Sequoia 15.4 on a Macbook air with M4 processor generates the following problem upon starting it in a terminal: dyld[10154]: dyld cache '(null)' not loaded: syscall to map cache into shared region failed dyld[10154]: Library not loaded: /usr/lib/libSystem.B.dylib Referenced from: <0144F82E-003C-37A9-A544-9AE6336E549B> /Users/markuswinterer/bin/rmcxas Reason: tried: '/usr/lib/libSystem.B.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/usr/lib/libSystem.B.dylib' (no such file), '/usr/lib/libSystem.B.dylib' (no such file, no dyld cache), '/usr/local/lib/libSystem.B.dylib' (no such file) zsh: abort rmcxas This occurs only about every 5th time the code is started.

Hello, I'm developing a macOS application that uses the Virtualization framework to run Linux virtual machines (specifically Ubuntu and Fedora) on Apple Silicon Macs. I've noticed that while the macOS host properly supports all trackpad gestures, the two-finger tap gesture for right-click does not work within the Linux guest. Only the primary click is recognized. This behavior is consistent across different Linux distributions and desktop environments (GNOME, KDE, etc.). I would like to confirm: Is the macOS Virtualization framework expected to support trackpad gestures such as two-finger tap for right-click within Linux guest VMs? If not currently supported, is there a known workaround to enable right-click functionality for the trackpad in Linux guests? (e.g., configuration changes in the VM, Linux kernel input modules, or framework-level adjustments.) Any insights or suggestions would be greatly appreciated. Thank you!

So, as we found out from WWDC, the migration to Apple Silicon is inevitable. Does anyone have a good recommendation for a replacement for Macintosh Common Lisp on Apple Silicon? I was using it back in the MPW days and struggling to keep the Lisp code working, but Apple Silicon has thrown a money wrench at it! Thanks in advance for any advice on any available Apple Silicon Lisp development tools!

I added an Apple Watch app target for an iOS app. If I install it directly through Xcode it runs, however it seems to be able to communicate with iphone through Watch Connectivity framework and once I close the app it seems to uninstall itself from the watch. When I installed the iphone app frist, the app does not show up on the available apps on the iphone Watch application, what could be the issue ? The iphone app was created using react native through expo. Testing Devices Iphone 13 pro max IOS 26.0.1 --- Apple Watch Series 4 WatchOS 10.6

Hi everyone, I'm developing a visionOS application using Unity with an enterprise developer account. I applied for the Main Camera Access entitlement, but at the time of submission, the email address associated with my Apple ID was deactivated, so I couldn’t receive any email communication from Apple. Later, I updated the email address for my Apple ID. Now, in the Apple Developer portal under Identifiers, I can see that my app has been granted Main Camera Access, and I can also add the corresponding capability in Xcode. However, according to Apple’s documentation(https://developer.apple.com/documentation/visionos/building-spatial-experiences-for-business-apps-with-enterprise-apis): “To use entitlements, you need to include both the entitlement file and a corresponding license file in your app. After Apple approves your app for one or more entitlements, you receive a license file, along with additional instructions.” I never received this license file, possibly due to the deactivated email. I don't know where to find it or how to retrieve it now. What exactly is this license file? If it was originally sent to an unreachable email, how can I request it again or get it resent? Where in the Apple Developer portal (or elsewhere) can I access or download this file? Any help or guidance would be greatly appreciated! Thanks in advance.

I've created an installation package and it is failing to install on macOS 15.6. The package is, I believe, properly notarized, since it will install correctly on other macOS versions, including 15.5 The only clue I have is the output from installer: installer[8015] : Opened package is not the same at install time installer[8015] : Unable to use PK session due to incompatible packages. Terminating. installer[8015] : Install failed: The Installer could not install the software because there was no software found to install. The installer consists of a a single "component" package, and the outer "product" package. The component package is present, and I can successfully run installer manually to install it, so I don't think the component package is corrupt. Has anyone else encountered this? Are there any tools available to help me diagnose the issue? The logging is not helpful.

Hello Apple Support, I’m facing an issue with Background Fetch in my React Native project. When I click on Simulate Background Fetch in Xcode, everything works as expected on the iOS Simulator—background tasks run smoothly, and data is fetched without issues. However, on a real device, the app goes to the background but doesn’t execute any of the scheduled background tasks, and it also remains in the background without terminating. Here’s some additional context: React Native Project: I’m using React Native to develop this app, and the background tasks involve: Getting User Location: Fetching the user’s location in the background. API Calls: Calling an API to fetch necessary information based on the user’s location. Scheduling Notifications and Alarms: Scheduling notifications and alarms based on the API response data. Simulator vs. Real Device: In the iOS Simulator, all these background tasks trigger and function correctly when I simulate Background Fetch. On the real device, however, none of these tasks are triggered when I try to simulate Background Fetch. The app only moves to the background without performing any tasks or getting terminated. Device and Configuration Details: iOS Version: 17 Device Model: Iphone xs, Iphone 11, iphone 7 Background Modes: Background Fetch is enabled in Capabilities, and I’ve set the fetch interval to the minimum for testing. I’ve verified that all configurations are correctly set, and I’ve tried restarting the device and Xcode, but the issue persists. Is there something specific about Background Fetch that could prevent it from functioning as expected on physical devices? Any guidance on troubleshooting or additional steps would be highly appreciated. Thank you!
