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 :(

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!

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!

USB audio/midi interface with OS 26 Tahoe
The first Beta install stopped recognizing a Yamaha USB audio interface. The next two installs brought the recognition back. The last Beta install doesn't recognize the interface completely. The midi implementation works but the audio implementation isn't recognized in Audio/Midi setup. This might be something to look at in the next Beta release or something audio interface venders should look at in their next driver release.

How Should a Beginner Properly Start iOS Development? Seeking Advice from Experienced Developers
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!

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.

Mac Studio – Wake from sleep – Desktop picture not stretching to fill Desktop
On wake from sleep the Mac Studio's Desktop picture is shown in actual resolution instead of stretched to fit screen. For example, a picture which is 2059 × 1371 is shown at that resolution on a 5K Retina screen and so only fills about 60% of the screen area. It starts with the picture positioned in the top left corner but sometimes moves down the screen. This behaviour does not change if the screen is scaled up or down – the picture size is also scaled. Notice that icons on the Desktop are displayed in the correct position. At the same time, the Dock is shown at the bottom of the picture instead of at the bottom of the screen. Usually, the Desktop redisplays correctly. But increasingly, the only solution is to log out and in again. This might be related to my other question on the Desktop picture Pref Pane. See attached example which is a full screen capture i.e. command-shift-3 (with my personal details obscured):

About region detection in the iBeacon app
We plan to use signals emitted from iBeacon to perform region detection in an app currently under development. We would like to know if region detection (didEnterRegion) can be performed when the app is in certain states. Region detection must be performed reliably. Is it possible to perform region detection in all of the following situations? • When the app is in the foreground • When the app is in the background • When the app is force-closed • When the smartphone is in sleep mode • When the smartphone is restarted Translated with DeepL.com (free version)

Apple Pencil Pro not staying connected in iPadOS26 beta
I have a new M4 iPad Air and a brand new Apple Pencil Pro. It was working well until I installed iPadOS 26.0 (23A5297m) beta. Now, when using GoodNotes to write the Pencil functions for about 6-8 seconds and then disconnects for 2-3 seconds and then reconnects. You can imagine how disruptive this is. It does the same thing trying to highlight in the Kindle app, so I think it is an iOS issue. As I write this, I am discovering that the Pencil is not wanting to stay connected at all despite showing up in the list of Bluetooth devices and connecting temporarily. I've tried forgetting and reconnecting the Pencil several times. It is charged to 100%, and I receive the alert that the iPad detects the Pencil. Is anyone else having this issue? Do I need to assume this is being addressed?

18.4 Beta sent iPhone 12 into boot loop
I installed the iOS 18.4 developer beta on my iPhone 12 last night, and it ended up sending my phone into a boot loop—at least that's what it looks like. Phone alternates between totally black screen and the Apple logo screen every 5 seconds or so. The phone isn't responding to force restart, isn't showing up in Finder to try to factory reset, etc. My guess is the update was corrupted in some way? Did this happen to anyone else? Any ideas about what's going on?

Urgent: Locked Account Holder – Need Help Transferring Account Holder Role
Hello Apple Developer Community, I’m hoping someone can advise me on a serious issue. Our organization’s Apple Developer Program account has been effectively locked because our Account Holder’s Apple ID is inaccessible. I need to either unlock that Apple ID or transfer the Account Holder role so we can manage our apps. I’ve already reached out to Apple Developer Support, but so far, I haven’t received a response. This situation is critical because our clients rely on us to maintain and update our apps. Key details (some info is masked for privacy): • We’re enrolled as an Organization/Company. • The current Account Holder’s Apple ID is locked and cannot perform any actions. • I have admin/manager access through another Apple ID. I’ve reviewed the documentation on transferring the Account Holder role, but it appears the transfer can only be initiated by the current Account Holder, which is impossible at this point. If anyone has encountered a similar issue or knows a more efficient route to escalate, I’d be extremely grateful for your insights. Thanks in advance for any advice you can share. This is critical to our organization, and we’d appreciate any pointers on how to navigate or expedite the support process.

Change Developer Forum Username
Hi There, Last year, I changed my company name from SugAR Labs to All Immersive. My current developer forum username is "SugAR_Labs" and I would like to change it to "All_Immersive" to match my new company name. I was advised by developer support on a phone call that there is not a way for me to do this myself. They referred me to a post like this to see if someone could help. Can someone help me make the change? Thanks!
