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

Hello, I’m developing my project for the Swift Student Challenge and I have some questions about the platform it will be tested on. If I create an iOS app that uses ARKit, for example, will it be evaluated on a real iPhone or only in a simulator on a Mac? I ask this because some functionalities, such as camera-based augmented reality, don’t work properly in the simulator.
I’d like to better understand the guidelines to ensure my project functions correctly during the evaluation.
Thank you!
Is anyone else having trouble posting to the forums? I can't get past form validation.

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?

It's Thursday, March 27th 2025 and I'm living in the UK, I have completed my project and submitted it before February 23rd and got the confirmation email and on March 27th, it says results are out but even after I wait for a long time, I still get the same message: We’ve received your submission.
We'll send you an email when results are posted. Even after I come back 16 hours into the day which is 4PM GMT, so I want to know where to see the results anywhere else or if it's just a delay.
Hello,
i am currently running iOS 18.4 Public Beta (22E5232a) on an iPhone 16 Pro and i have problems with getting emails in the native mail app. i cannot receive any email from some of my email addresses. there is an “account error“ message that says:
“Cannot get mail, The connection to the server failed.”
When i enter my password again in settings it works for 1-2 days then stop working. On my iPhone X running iOS 16.7.10 it works perfectly. Only bugs on my iPhone 16 Pro.

I'm concerned that the Apple Vision Pro is too costly for low-income developers to develop for. Any thoughts?
I'm preparing my submission for the Swift Student Challenge, and I have a couple of questions regarding the development environment.
Is it allowed to use Xcode to program my scene, or do I have to use Swift Playgrounds?
Can I use iPadOS 18 for development? I noticed that Swift Playgrounds currently only supports up to iPadOS 17.5, but I would like to use RealityView, which is only available starting from iPadOS 18.
I appreciate any clarification on this. Thanks in advance!

Hey team,
I have an app in CarPlay where i was pushing the CPNowPlayingTemplate as follows:
self.interfaceController.pushTemplate(CPNowPlayingTemplate.shared(), animated: true)
This used to work perfectly, but suddenly I have started to get this error
NSInvalidArgumentException: Unsupported object <CPNowPlayingTemplate: 0x119a0b5c0> <identifier: 6EE4E5A9-B1FB-4341-A485-78D7DDEBD8D0, userInfo: (null), tabTitle: (null), tabImage: (null), showsTabBadge: 0> passed to pushTemplate:animated:completion:. Allowed classes: {(
CPActionSheetTemplate,
CPAlertTemplate,
CPVoiceControlTemplate,
CPTabBarTemplate,
CPListTemplate,
CPInformationTemplate,
CPContactTemplate,
CPMapTemplate,
CPGridTemplate,
CPSearchTemplate
)}
How is this possible? Even on Apple docs, it says to pushTemplate
Refer

When I updated IOS 26.1, When someone call me over voice call phone kept vibrating after call has been picked for 15 sec. Can you please check what’s the issue

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.

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.

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 :(
Hello everyone,
I'm a 2nd-year Computer Science student who's excited to dive into iOS development, and I'd really appreciate some guidance from the experienced developers in this community.
MY CURRENT BACKGROUND
I have a solid foundation in programming fundamentals through my university coursework (data structures, algorithms, OOP concepts), and I'm familiar with general software development principles. However, iOS development is entirely new territory for me, and I want to make sure I start on the right foot.
WHAT I'M LOOKING TO UNDERSTAND
Learning Path & Technologies
Should I start with UIKit or SwiftUI? I've heard conflicting opinions about this
How important is it to learn Objective-C in 2025, or should I focus solely on Swift?
Are there any foundational Apple frameworks I should prioritize learning early on?
Roadmap & Structured Learning
Is there a recommended roadmap or learning sequence I should follow?
What skills/topics should I master before moving to more advanced concepts?
Should I learn iOS development in a linear fashion, or is it better to learn as I build projects?
Are there any official Apple learning paths or certifications worth pursuing?
Common Mistakes to Avoid
What are the most common pitfalls beginners face when starting iOS development?
Are there any bad habits or patterns I should consciously avoid from day one?
What misconceptions did you have as a beginner that you wish someone had corrected earlier?
Project-Based Learning
What types of projects would you recommend for someone at my level?
Should I build several small apps or focus on one comprehensive project?
At what point should I start contributing to open-source iOS projects?
Best Practices & Design Patterns
Which iOS-specific design patterns (MVC, MVVM, etc.) should I learn first?
How can I develop good habits around memory management and app architecture from the beginning?
What resources do you recommend for learning iOS best practices, not just syntax?
Apple Ecosystem & Tools
Beyond Xcode, what tools should be in my toolkit?
How important is it to learn about TestFlight, Instruments, and other Apple developer tools early on?
Should I get comfortable with CocoaPods/SPM from the start, or wait until I'm more experienced?
MY GOALS
My goal is to build a solid foundation over the next 6-8 months, create a few portfolio-worthy apps and pursuing iOS development as a career path after graduation.
SPECIFIC QUESTIONS
How many hours per week would you recommend dedicating to learning iOS development while managing university coursework?
What's the best way to stay updated with Apple's annual changes and new frameworks?
When should I start thinking about publishing apps to the App Store?
Are there any mentorship programs or communities specifically for beginner iOS developers you'd recommend?
I know this is a lot of questions, but I genuinely want to learn the right way rather than picking up bad habits I'll have to unlearn later. Any advice, resources, or personal experiences you're willing to share would be incredibly valuable to me.
Thank you in advance for taking the time to help a beginner. I'm committed to putting in the work and learning properly!

The latest Beta update 18.5.4 has caused connectivity problems with my car (Skoda Enyaq) whereby there is no connection via Bluetooth or the cars internal WiFi.
Also contacts will not download to the care which is very frustrating.

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!

Why can’t Apple just release a version that put the most frequent used emoticons in the most left side of the emoticons keyboard???
Each person always uses the same 20 or 30 emoticons.
How this could be reported to developers?
Thx

Installer hangs during installation of Epson iProjection app on macOS 26 (Tahoe)
When running the installer for Epson iProjection Ver.4.03 on macOS 26 (Tahoe) RC, the installation process hangs midway and becomes unresponsive.
Run the installer for Epson iProjection Ver.4.03 from the following link:
https://support.epson.net/setupnavi/?LG2=EN&OSC=WS&PINF=vpapp&MKN=EB-770Fi
The installer hangs during the installation process and does not proceed.
(Please refer to the attached screenshot for details.)
The installation should complete successfully without hanging.
<Version / Build>
macOS 26 RC (25A353)
The installation error log is as follows:
RemotePlugin: Epson iProjection Ver.4.03 terminated with error: Error Domain=com.apple.ViewBridge Code=17 "(null)"
UserInfo={com.apple.ViewBridge.error.hint=connection to view service became invalid -- benign unless unexpected,
com.apple.ViewBridge.error.description=NSViewBridgeErrorDisconnection}
Is this behavior expected due to changes introduced in macOS 26?
Are there any recommended workarounds or mitigation steps?

Hi Ed Ford,
thank you for your response. I tried to reply directly in the forum with the requested output,
but I keep receiving an error message ("Your post couldn’t be saved. Please try again in a few minutes.").
It seems I cannot currently post a follow-up reply.
Just to notify you: I ran the command you suggested, but my shell reports
zsh: command not found: devicectl.
Thank you!
