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.

iOS 26 Beta 1 : Banking and Government apps crashing
(It’s my first post so idk if i’m in the right place) I have been testing iOS 26 since launch and it is great (kind of buggy but that’s to be expected). I have come across an issue though : government and banking apps either crash or get stuck on splashscreen on launch. Do you think it is something that is gonna be fixed on the apple side of things, or that it’s gonna be for the developers to figure out compatibility ? (I am asking because governments don’t tend to be quick to fix problems so i am hoping it not the latter) Any idea?

Third-party apps reset and force close after launch on iOS 26 Developer Preview
Hi everyone, After updating to iOS 26 Developer Preview on my iPhone, I’m experiencing a repeated issue with certain third-party apps. ⸻ -Issue details: • The apps open as if freshly installed, showing the onboarding or login screen each time • User session is completely lost (no saved login or data) • Around 10 seconds after launch, the app automatically closes • It disappears from the app switcher (not just backgrounded) • This happens every time, with no crash message or error shown ⸻ -What I’ve tried: • Reinstalled the apps • Restarted the device • Toggled Face ID, Background App Refresh, etc. • Confirmed I’m running the latest iOS 26 Developer Preview build ➡️ Problem still occurs exactly the same way ⸻ -Feedback status: I submitted a report via Feedback Assistant with a screen recording and full reproduction steps. No response yet after several days. ⸻ -Looking for: • Confirmation from others with similar issues • Info on whether this is already being tracked by Apple • Whether it’s worth resubmitting a new Feedback report Thanks for any insight.

Mac Mini M1 Firmware Restore
Hi, After installing Macos 26 Beta on my Mac Mini M1 it doesn't boot. On the front panel there is an orange blinking light. The monitor doesn't recognize it. In DFU mode my other Mac Mini (M4) recognizes it but I can't restore it from Configurator (see print). Thanks for your help.

Is this an ios 26 beta bug?
After updating my iPhone to iOS 26 beta, images displayed inside an in-app WebView (WKWebView) suddenly look almost black, as if a black overlay were sitting on top of them. The same image files are delivered from the server without any problems. I inspected the DOM and CSS in Safari’s remote debugger and confirmed that no extra overlay element or dark background layer is being injected. The effect only appears inside the WebView on iOS 26 beta; the same page renders correctly on earlier iOS versions and on desktop browsers. I would like to understand what change in iOS 26 beta could be causing this darkening effect.

iPadOS26 DFU Mode not showing in Finder
iPadOS 26 Dev Beta 1 - need to do a restore via DFU mode. I made sure iPad in normal mode shows up in Finder and I can see device details. When I boot into DFU mode (I have kept the ipad connected to mac), it does not show up in Finder. No matter what combination of plugging/unplugging cables, rebooting, again into DFU mode, it will not show up in Finder. Looking for steps to resolve this, or do I need to wait until beta 2 to resolve this?

Network filtering/VPN configurations not working
Hello, I'm experiencing issues with multiple apps on macOS related to network-related tasks. FIrst, I had problems with the network filter on Avast security. It told me to allow net work filtering, so I pressed the popup button that said allow filtering, but did nothing and gave me a error. Later on, on Nord VPN didnt work aswell, when I had to grant permission to configure a VPN. It didn't even give me a description of the error, just said something went wrong. I contacted NordVPN support, which didnt do anything exept for telling me to uninstall avast and restart my mac, which I did but was useless. Please help me.

CoreData error: SQLCore dispatchRequest: no such table: ZAPPSETTINGS. I/O error opening
Issue with SwiftData: “no such table: ZAPPSETTINGS” and SQLite I/O error on app launch Hello, I’m encountering persistent errors with SwiftData in my SwiftUI app related to Core Data’s underlying SQLite database. Despite defining my models correctly, the app fails to initialize the persistent store, throwing the following error on startup: CoreData error: SQLCore dispatchRequest: no such table: ZAPPSETTINGS. I/O error opening database at /.../default.store. SQLite error code:1, NSSQLiteErrorDomain=1. File “default.store” couldn’t be opened. Context The error only appears concerning my AppSettings model. I have another model, LocationPoint, which appears correctly defined and used. I have tried deleting the app, resetting the device, and cleaning builds but the error persists. The error message suggests the database file is present but the table for ZAPPSETTINGS (the Core Data table for AppSettings) does not exist. Code Samples Main App Entry import SwiftData import SwiftUI @main struct Krow3_0App: App { @State private var userLocationManager = UserLocationManager() @State private var geocodingViewModel = GeocodingViewModel() @State private var locationSearchViewModel = LocationSearchViewModel() @State private var router = Router() var body: some Scene { WindowGroup { LaunchView() .environment(userLocationManager) .environment(geocodingViewModel) .environment(locationSearchViewModel) .environment(router) .modelContainer(for: [LocationPoint.self, AppSettings.self]) } } } AppSettings Model import Foundation import SwiftData @Model class AppSettings { var isMetric: Bool init(isMetric: Bool = false) { self.isMetric = isMetric } } What I’ve Tried Fully uninstalling and reinstalling the app on device and simulator. Resetting the simulator/device. Cleaning the Xcode build folder. Verifying the schema logs which correctly list both LocationPoint and AppSettings. Changing model names to avoid potential conflicts. Adding .modelContainer configuration with autosave enabled. Questions Is there a known bug or limitation with SwiftData concerning certain model setups or naming? Could this be related to how the data container initializes or migrates schemas? Are there recommended debugging or migration steps to resolve “no such table” SQLite errors with SwiftData? How can I safely reset or migrate the persistent store without corrupting the database? Any insights or suggestions would be greatly appreciated! Thank you!

Selling your first app
How long was it between putting your first app on the App Store (that had a paid component to it like IAPs) and getting your first sale? I'm working on an app at the moment that I plan on putting up for a small one time fee. I'm curious to know what people's different experiences were with this. What was your app and how did it go?

How to detect if an iPad is configured as a Shared iPad (Apple School Manager)?
I'm working on an iOS/iPadOS app and need to determine programmatically whether the device is a Shared iPad as configured through Apple School Manager (ASM). Shared iPads allow multiple users to sign in with Managed Apple IDs and are typically used in educational environments. I want to identify this configuration at runtime within my app. I’ve looked into UIDevice, NSProcessInfo, and MDM-related APIs but haven't found a reliable way to detect whether the current device is a Shared iPad. Is there an API or method to check if the current iPad is configured as a Shared iPad (via ASM)? Any guidance or code examples would be appreciated.
