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

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.

Unable to register for Swift Student Challenge Meet with Apple Session
Pretty much what the title says, I received the email from Apple today regarding the three sessions that are being conducted for participants. When I open the link, I'm shown the button to register, but when I click register, I'm asked to log in, following which I'm redirected back to the same page except the register button is now missing. I'm unsure if it has registered me, and I haven't received any email confirming the same.

Guided Capture iOS analysis phase time?
I've just watched "Meet Object Capture for iOS wwdc23" and have installed and run the app. After taking > 120 images of my model I clicked the "Finish" button and the app is now showing a spinning pinwheel. It has been running for about 22 hours. Is it going to finish or should I kill it? TIA!

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.

Please Help! App won't open for 1 user, Just fades away.
[https://vimeo.com/manage/videos/1051990313) We are experiencing an issue where a user is unable to open our app on their iPhone 16 Pro Max running iOS 18.3. When the user selects the app, it begins to scale to screen size but then fades away without fully opening. It is unclear whether this is a crash or another issue. To troubleshoot, we created a simplified version of the app containing only a single screen displaying "Hello, World." The user experiences the same issue with this version, leading us to believe there may be a device-specific setting or compatibility issue at play. Steps the User Has Tried: Checked device storage – over 200GB available Offloaded and reinstalled the app Deleted and reinstalled the app Updated to iOS 18.3 Forced restart of the device Reset network settings Turned off VPN Despite these steps, the issue persists. We would appreciate any guidance on potential causes or troubleshooting steps to resolve this issue.

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

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?

MacPro 2019 Boot Screen Selection?
hi. I have a MacPro 2019, and I'm running Monterey at the moment. I have three screens. Two 4k screens, and a XDR in the center of them. My MacPro 2019 boots with the left screen showing the startup and login screen. I've previously had it boot to my XDR before the others. I'm not entirely sure why it moved to the left, but I need it back on the center screen. We used to just drag a happy mac icon from screens in the displays system preference. I don't see any method to change this startup and login screen. How do I choose the permanent bootup and startup screen (as my XDR!). Thanks. Dave

Expo crash on iOS simulator
I've been working on my mobile app project using Expo. Yesterday, when I tried to run the app again, the Expo Go in the iOS simulator got stuck on the screen showing "New update available, downloading..." and then crashed. I'm not sure what went wrong. It only provides a long error report. I ran an EAS build, which completed successfully, so I suspect the issue might be with the iOS simulator or Expo Go itself. Please help me out :(

Very strange behavoir of Safari.app, Notes.app on MacBook Pro
Is there a way to check whether third-party code can be inserted into parts of the ARM CPU architecture from outside? I have the paranoid impression that my MacBook Pro, M2 processor is being manipulated from outside. For example: Safari, when opened, displays pages scaled down without my conscious intervention, when clicked on the original size it scales back to normal for a short time and then implodes again; I use the navigation bar on the left excessively, it is my most important tool in Safari, today it was impossible to insert a link using drag & drop, the bar scrolls up or down very quickly; a behavior that I only know from Intel processors. For example, notes, I encrypted an important note, no problem even though photos and links are inserted, yesterday I could no longer open the note, neither on the MacBook Pro nor on the iPhone. When opening the notes app in the terminal on the MacBook Pro, an EXEC_CRASH report was generated. I have a terrible suspicion that the Apple branch in Munich is tampering with the devices and software of users in Germany. Sorry, I'm a big fan of Apple and its products, but this is very spooky. I just wanted to share my distrust with you!
