iOS 18.4 Upgrade Causes Installed Apps to Revert to Older Versions
We have observed an issue where upgrading an iPhone to iOS 18.4 causes installed apps to revert to significantly older versions. For example, if the App Store version is 1.0.284 and the user had 1.0.283 installed before the upgrade, after updating to iOS 18.4, the app version reverts to 1.0.208—which is nearly a year old. We suspect this may be related to iCloud backup restoration. Has Apple encountered similar cases, and is there a known resolution for this issue?

Geofencing Event Not Triggering When App is Killed and Not Opened After 2-3 Days
Hello, I’m facing an issue with geofencing events in my app. When the app is killed and not opened for 2–3 days, the geofencing event is not triggering when I re-enter the geofenced area. I’ve made sure that all necessary permissions (location, background refresh, etc.) are properly set in the app settings. Has anyone else experienced this? Is there a solution or workaround to ensure that geofencing works as expected even after the app has been killed for several days? Any help or insight would be greatly appreciated! Thanks in advance!

iOS 26: iPhone will not power on stuck on battery screen
I set iOS 26 to install overnight, put my iPhone 16 Pro on the MagSafe charger, watched it charge just fine, and went to sleep. When I woke up the iPhone showed the “plug into power” dead battery screen. I took it off MagSafe and put it back on. A half hour later the phone was warm but still wouldn’t power on, just showed the battery screen with a little red in it. I took it off MagSafe and plugged it into my iPad charging brick with USB cable to give it more power, still it did not turn on. I tried holding all the buttons to try to force a restart but didn’t work. For anyone else encountering this, do this to enter DFU mode and restore it. I had to do it a few times before I got the timing right. Plug into your Mac and open Finder (or apparently a PC with Apple Devices or iTunes) Press and quickly release volume up Press and quickly release volume down Press and hold right side button When the battery disappears and screen goes black, hold volume down and continue holding side button After a couple seconds release the side button and continue holding volume down A prompt to allow connecting to the iPhone should appear after a couple seconds, click Allow, and it’ll say the iPhone entered DFU mode - proceed to restore the firmware

Xcode-beta project ORSOFINAL: SwiftShims & C99 PCH errors after migration from Xcode stable
Hi all, I’m running into a persistent build issue with my Swift project ORSOFINAL after migrating from Xcode stable to Xcode-beta.app (June 2025 version). ⸻ 💥 Errors displayed: 1. C99 was enabled in PCH file but is currently disabled 2. module file .../ModuleCache.noindex/SwiftShims-AXUM98L131W4...pcm cannot be loaded due to a configuration mismatch with the current compilation 3. missing required module 'SwiftShims' ⸻ 🛠 What I’ve already tried: • xcode-select -s /Applications/Xcode-beta.app/Contents/Developer • Deleted ~/Library/Developer/Xcode/DerivedData, ModuleCache.noindex, Archives, and Products • Ran sudo xcodebuild -runFirstLaunch • Clean Build Folder in Xcode-beta • Verified Command Line Tools setting points to Xcode-beta ⸻ ❓Looking for guidance on: • Whether this is a known bug in Xcode-beta • If SwiftShims/PCM conflicts are expected between versions • Best practices to safely migrate from Xcode stable to beta for Swift-based projects Any advice is much appreciated. Thanks, Mathéo

Unify Native iOS Utility Apps into a Single Modular AI-Enhanced App (Apple Assist)
Hello Apple Developer Community, I'd like to propose a system-wide enhancement for future versions of iOS: the integration of native utility apps — Calculator, Compass, Voice Memos, Magnifier, Measure, Weather, and Translate — into a single unified app, tentatively called Apple Assist. The vision is to provide: A modular interface where users can enable/disable tools as needed. Smarter workflows with proactive suggestions based on context (time, location, task). AI-powered interaction through voice and Apple Intelligence (Advanced Siri). Benefits: Reduces icon clutter on the Home Screen. Simplifies the user experience with a single access point. Creates opportunities for automation and accessibility. Imagine saying: “Hey Siri, record a quick note and measure the table” — and the app smartly loads those modules on demand. Would love to hear feedback from the community — and whether Apple might consider something in this direction for iOS 19 or beyond. Best regards, Jose Luiz Horta Barbosa Maurity Cruz

Ghost entry remains in “Allow in Menu Bar” after app deletion — macOS Tahoe beta
I’m experiencing an issue on macOS Tahoe (Developer Beta, July 2025) related to the new “Allow in Menu Bar” section in System Settings. After uninstalling the application Backdrop (developer: Cindori), the entry com.cindori.Backdrop.Wallpaper still appears in the list of apps allowed to show in the menu bar, even though: — The app and all its associated files have been fully deleted. — The LaunchAgents files in ~/Library/LaunchAgents and /Library/LaunchAgents have been removed. — Preferences have been deleted via defaults delete com.cindori.Backdrop and defaults delete com.cindori.Backdrop.Wallpaper. — The system has been restarted. It seems the “Allow in Menu Bar” section keeps phantom references to apps or agents even after complete cleanup. Could you please confirm if this is expected behavior (perhaps for future reactivation) or a bug? Is there any official method or recommended command to permanently remove such residual entries from this list? Thank you very much for your help and clarifications.

Unable to select 4K resolution on Sharp 8TC60DWTX (8K) display.
Problem description: Connected to a Sharp 8TC60DWTX (8K) display, but unable to select 4K resolution Setup Condition Apple MacBook Pro 16-inch M4 Max Sharp 8TC60DWTX (8K) 3.Duplicate Procedure After connecting to 8K MNT and select 4K solution, it still display as 8K. Vendor analysis: 8K60 shows no image; switching to 30 Hz works normally → After analysis, we found that the 8K60 timing output from the MacBook is incorrect. The horizontal blanking (H-CBlanking) is too small to accommodate the audio data, so the RTD2191E does not output video to the monitor. → This issue does not occur on Windows platforms, confirming that this is a host-side issue.

Have not received weekly analytics email for over a month
The last "App Store Connect: App Analytics Weekly Summary" email I received was June 3. My apps are still up and the emails are not going to spam. In my Apple Developer settings, "App Analytics Weekly Email Summary" is still set to on (i.e. "Receive a weekly email."). Coincidentally, on June 9 I received an email about updated agreements and guidelines, which I hadn't logged in to accept until today. Is this related, and if so, why should it be? If something else is causing the missing emails, how can that be resolved?

Brightness slider UI bug when long-pressed in iOS 26
Hi! I found a UI bug in iOS 26.0 (23A5276f). When you swipe down from the top right to open Control Center and adjust brightness using the slider, everything looks normal. However, if you long-press the brightness slider, the brightness knob detaches from the base. The button becomes smaller while the frame remains the same, making the UI asymmetrical and misaligned. This happens consistently and is clearly a layout issue.

CGPDFDocument Rendering Issue with Custom Fonts in iOS 18
we’ve identified that our PDF rendering pipeline leverages the native CGPDFDocument APIs to convert PDF pages into images. However, in the latest release of iOS 18, the provided document fails to render even at the CGPDFDocument level. Our analysis suggests that the issue may stem from the embedded custom fonts not being correctly processed in this version of the iOS platform. This appears to be consistent with several other reports and discussions around font rendering problems introduced in iOS 18, particularly involving subset fonts. We’ve attached a collection of relevant community threads and references, including: Apple Developer Discussion: Subset Font Rendering Issue in iOS 18 Given that our implementation is tightly coupled with Apple’s native PDF rendering APIs, this issue presents a blocking limitation for us. With your permission, we would like to use this document as a sample case to formally report the issue through the appropriate Apple Developer forums and feedback channels.

Terrible treatment by Apple Dev support team
I paid for my developer account on the 13th of June 2024 (1 week ago). My ID was approved. However, I still don't have access to the account. When I go to check the status of it, it is asking me to pay again. I then tried to email the team, however only received useless, timewasting responses, such as "Please go to developer.apple.com/enroll to enroll for an apple dev account", which I already told them prompts me to pay again and verify my ID again. I then tried to call them, and they said they had to re-verify my ID and would call me back in 10 mins, but I never received a call back. I also couldn't call them again because it wouldn't let me request another call from them. I then emailed them, but still haven't received a response. The next day I tried to request another call from them, during their opening hours at Thursday 4pm AEST, (they are open Mon-Fri 9am-5pm AEST see https://developer.apple.com/support/worldwide-telephone-hours/) however it still says that "Phone support is currently unavailable". I tried to email them but now I am getting no responses at all. I tried to contact the apple support through the iMessage chat, however I was only put on call with a lady who was helpful, but couldn't even do anything as she was only generic support. She couldn't even schedule me a call or transfer me to the developer team, even though it was within their working and calling/support hours. I have tried to refund my developer account, but apparently that purchase is "illegible for a refund". This is the treatment I get from apple for paying $100 USD. An entire week of being left on blank. I don't know what to do. I paid 100 bucks for an account which I can't even use, and the support hasn't helped me for an entire week. My emails being left on blank, and I can't even call them. If anyone from apple or anyone that could help me sees this, please contact me ASAP at makrypodisc@ hotmail.com or reply to this thread. Thank you.
