Hi, I found an issue related to dynamic app icon changes using UIApplication.shared.setAlternateIconName specifically on iOS 26.1. Test Scenario 1. Change icon using: UIApplication.shared.setAlternateIconName(TestIcon) → Works correctly. 2. Revert to primary icon using: UIApplication.shared.setAlternateIconName(nil) Issue on iOS 26.1 For some users, the device does not revert back to the primary icon when calling setAlternateIconName(nil). To handle this case, we attempted to force the primary icon by explicitly calling: UIApplication.shared.setAlternateIconName(AppIcon) However, on iOS 26.1: • As soon as this call is made, the entire setAlternateIconName API stops working. • Every subsequent call to setAlternateIconName fails. • The API begins returning errors (e.g. NSPOSIXErrorDomain code 35). • The issue persists until the device is rebooted. Expected Behavior We understand that providing AppIcon should not change the icon (since primary icon is restored using nil), but on earlier versions of iOS (≤ 26.0):

Hi everyone, I’m currently experimenting with App Intents and I’m trying to customize the section titles that appear at the top of groups of intents inside the Shortcuts app UI. For example, in the Phone shortcut, there are built-in sections such as “Call Favorite Contacts” and “Call Recent Contacts” (see screenshot attached). Apple’s own system apps such as Phone, Notes, and FaceTime seem to have fully custom section headers inside Shortcuts with icon. My question is: 👉 Is there an API available that allows third-party apps to define these titles (or sections) programmatically? I went through the AppIntents and Shortcuts documentation but couldn’t find anything. From what I can tell, this might be private / Apple-only behavior, but I’d be happy to know if anybody has found a supported solution or a recommended alternative. Has anyone dealt with this before? Thanks! Mickaël 🇫🇷

I am an open source developer, who just switched to macOS a few weeks ago. I am basically looking for an alternative to Linux' /etc/nsswitch.conf. Not for custom DNS resolution, that's an easy problem to solve, but for users / groups / hosts resolution via custom network modules. Basically looking for a way how I can hook up into the OS in kind of the same way as an LDAP client would do, and provide my own NSS modules. Just for reference, I am developing rauthy which can do PAM authn / authz in combination with rauthy-pam-nss. It works perfectly fine on Linux systems, and I now want to make it work on macOS as well. I already know that macOS is running its mDNSResponder for DNS instead of having the nsswitch.conf, but I have not found an answer for users, groups and hosts.

I noticed that I cannot even tell that an NSBox is being used on macOS Tahoe when the system is in light mode. The 'box' background can't be seen so it makes it appear that the subviews in the box aren't positioned correctly (because they are inset from the subview outside the box). There is no visual indicator that that subviews inside this box are grouped together because well, you can't see the box at all. In Interface Builder the box looks fine at Design Time in Light Mode. In Dark Mode the box looks fine at design time and at run time. Just figured I'd throw that out there.

Stale TBD Files Cause Runtime Crash When Framework Changes from Dynamic to Static Summary When using EAGER_LINKING=YES, Xcode generates TBD files for dynamic frameworks. When a framework changes from dynamic to static, Xcode doesn't remove the stale TBD, causing dyld: Library not loaded crash at runtime. Environment Xcode 16.4 (16F6), macOS Darwin 24.6.0, iOS Simulator 18.5 Steps to Reproduce Project Structure: MainApp (EAGER_LINKING=YES) ProjectA/SharedLib (dynamic, mh_dylib) ProjectB/SharedLib (static, staticlib) Steps: Build with ProjectA (dynamic framework) → TBD created in EagerLinkingTBDs Switch workspace to ProjectB (static framework) without cleaning DerivedData Build again → BUILD SUCCEEDED Run app → CRASH: dyld: Library not loaded Root Cause Xcode adds -F EagerLinkingTBDs before -F Build/Products: -F/.../EagerLinkingTBDs/Debug-iphonesimulator ← checked FIRST -F/.../Build/Products/Debug-iphonesimulator ← checked SECOND The linker finds the stale TBD first and treats the framework as dynamic,

As a developer I have a question I would like cleared up. We offer two tiers of annual subscriptions in our apps. These subscriptions are under the same subscription group in App Store connect. My question is, if a user purchases tier 1 of the annual subscription for $10.00, and uses it for 6 months; then chooses to upgrade to tier 2 which costs $20.00 per year. Would the user be pro-rated the difference in price i.e. charge only another $10.00 at the time of the upgrade., or are they charged $20.00 and then refunded the difference in their remaining lower tier subscription? I keep finding inconsistent answers across the Apple community forums on this.

Hello, I would like to report a situation that appears to be outside the normal App Review process and may indicate a system issue or an unintended internal flag on my app. My app Vocheo (Bundle ID: com.vocheo) has been stuck in “Waiting for Review” for an unusually long period — a total of ~40 days since the first 2.0 submission on October 26. Across multiple submissions, the review has never meaningfully started. Here is a summary of what happened: Timeline Overview • First 2.0 submission: Oct 26 • Most recent submission: Dec 2 (version 2.1.5) • Total time stuck: ~40 days • Longest individual “Waiting for Review” period: 18 days • Another long period: 8 days • All withdrawals were done on the same day and resubmitted immediately — they did not resolve the issue. Only two submissions ever entered “In Review”, and both resulted in very fast, template-style rejections within minutes. After those, every new submission returned to weeks of “Waiting for Review” with no progress. Attempts to Resolve I hav

I'm trying to sync authentication data from my iOS app to a Safari Web Extension using App Groups, but the extension isn't consistently receiving the data. Setup: App Group: group.com.airaai.AiraApp (configured in both app and extension) iOS app writes auth data using UserDefaults(suiteName: group.com.airaai.AiraApp) Extension's Swift SafariWebExtensionHandler reads from App Groups in beginRequest() Extension's JavaScript reads from browser.storage.local Problem: Extension popup always shows logged out even when: User is logged into main iOS app Auth data exists in App Groups (verified via native module logs) Handler successfully writes test values to extension storage Current Behavior: Handler CAN read from App Groups ✅ Handler CAN write test values to extension storage ✅ But auth data doesn't appear in browser.storage.local when popup checks ❌ Popup reads empty keys even though handler logged writing them Code: // Handler reads from App Groups guard let
