Your app still contains features that mimic the iOS interface or behavior. I have a simple app that uses a NavigationSplitView 3 panels I have a section for Filters and User created Categories in Panel 1 A list of Requests from the selected Filters/Categories in Panel 2 and details of a request in Panel 3 It's designed to be simple and easy to use. How can it NOT mimic the iOS interface if I am using their own APIs? What should I do to get around this

Hi Kevin, Thank you for the clarification. However, we want to emphasize that the decision to have cupsd ignore one of its main configuration files is a major breaking change. This is not just a tightening of the sandbox but a major departure from documented CUPS behavior (https://www.cups.org/doc/man-cups-files.conf.html). By ignoring cups-files.conf, macOS disables essential administrative controls required for non-standard printing environments. As such, we hope the team will reconsider this approach. If a fixed configuration is necessary for the default security posture, there should still be an alternative that allows legitimate, authorized software to operate in “relaxed” mode. In terms of supporting CUPSD_SANDBOXING_STRICT, am I correct that these two points are the real issues here, not the path limitations? As we mentioned earlier, it is a combination of all three (file/folder access, sub-process handling, and network calls). We are actively working on modifying our backend/filter to accommo

Issue After upgrading to Tahoe 26.2, print queues monitored by PaperCut no longer work. The print queue gets paused, and the jobs fail to print. This issue was discovered during our internal testing prior to the Tahoe 26.2 public release, and a growing number of our mutual customers have also reported it since then. Root cause This appears to be due to changes in the behavior of CUPS Sandbox restrictions, which prevent the backend (and filter) from reading/writing to the PaperCut install folder. Error messages From syslog. 2025-12-22 16:41:59.283761+1100 0x1daf61 Error 0x0 0 0 kernel: (Sandbox) Sandbox: papercut(5783) deny(1) file-write-data /Library/Printers/PaperCut/Print Provider/print-provider.log When trying to create a TCP socket from the PaperCut filter. 2025-12-15 19:50:08,403 ERROR: os_tcp_socket_create: getaddrinfo failed: nodename nor servname provided, or not known Technical details PaperCut implements print queue monitoring using a CUPS backend (and filter).

It seems that iOS does update markedTextRange for me. I tried the following code: func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool { if let markedTextRange = textView.markedTextRange { let markedText = textView.text(in: markedTextRange) ?? print(markedText = (markedText), replacementText = (text)) } else { print(replacementText = (text)) } return true } And get the following result when inputting あ and then か with Japanese Kana input method: replacementText = あ markedText = あ, replacementText = か Do you see the same thing? is markedText + replacementText not enough for you to determine whether the input is valid? I tested with iPhone + iOS 26.1(23B85), if that matters. Best, —— Ziqiao Chen Worldwide Developer Relations.

File Provider Extension Testing Mode -2014 Error Issue I'm developing a macOS File Provider Extension and encountering a -2014 (Extension not registered) error when using Testing Mode only.

I don't have the answer yet, but the explanation of the error code -2001 and -2014, as shown in the following, basically says your app bundle doesn't have a launchable file provider extension, which is pretty strange if your file provier works when the testing mode isn't used. /** Returned by NSFileProviderManager if no provider could be found in the application */ NSFileProviderErrorProviderNotFound FILEPROVIDER_API_AVAILABILITY_V3_IOS = -2001, /* Returned by the system to indicate that the system does not have any launchable `com.apple.fileprovider-nonui` application extension for this domain's app bundle. */ NSFileProviderErrorApplicationExtensionNotFound FILEPROVIDER_API_AVAILABILITY_V6_0_IOS = -2014, You mentioned the general com.apple.developer.fileprovider capability is not visible in Developer Portal and asked how to enable it, which confuses me a bit, because com.apple.developer.fileprovider is never a capability. Would you mind to share where you found the capability and why you believe it

Hi there. I am trying to figure out how to make a macOS Tahoe app in SwiftUI with a sidebar. The problem I’m having is that the icons are the wrong size. If you visually compare the resulting sidebar with any built-in macOS app (Finder, Notes, Mail, Music, etc.) the built-in apps all have larger icons and the spacing is different from my SwiftUI app, which has too small icons and (I think) wrong spacing. I am trying to figure out what SwiftUI code I need to write to get a sidebar that looks the same as the other built-in macOS Tahoe apps. It’s also important to note that Tahoe sidebars have larger icons at the top level, and in cases where the items have a disclosure triangle with additional items nested within, the nested icons have smaller icons. I have not figured out how to properly replicate this effect either. I have spent quite a lot of time on trial-and-error with various combinations of .frame() and .font() modifiers. However, none of the results look quite right to me, and besides that, I t
Thanks for your post. Extremely detailed and interesting. You're right that manually adjusting sizes with and isn't ideal for achieving consistency with native macOS apps, especially across different macOS versions. In previous macOS, I think, SwiftUI provided a way to automatically adjust sidebar icon sizes to match system standards by using modifiers and appropriate view hierarchies. Unfortunately, we are unable to provide any details regarding the design or code for Apple macOS apps. Additionally, the icon sizes may differ from the default icons provided by SwiftUI as you already point it out. Cannot even provide you a way to achieve a sidebar similar to built-in macOS apps, I would recommend for you can leverage the documentation at https://developer.apple.com/documentation/technologyoverviews/adopting-liquid-glass that automatically configures the list to adopt macOS sidebar conventions, including icon sizing and spacing. That Tech Note also provides many different tips to work with the new UI f

I am developing a binary SDK for consumption by others. When we updated to Xcode 26, any builds which are generated cannot be consumed by Xcode 16. The specifics lie in the optionals. The following Swift code generate a .swiftmodule func affectedApi() -> Int? { return 1 } In Xcode 16 it generated the following .swiftmodule in the framework. public func affectedIntApi() -> Swift.Int? In Xcode 26 it adds an if statement. #if compiler(>=5.3) && $NonescapableTypes public func affectedIntApi() -> Swift.Int? #endif That if statement prevents Xcode16 from seeing the API, and it causes compile failures. This happens regardless of which Swift version is used, and it only affects functions which use Optionals. Is there a way to prevent the compiler from wrapping the API in that statement?
If (in terminal) I type 'env', I'll see a line that looks like: LANG=en_GB.UTF-8 And I can parse that to get the 2-char 'en' locale-code, the sub-domain 'GB' and the character-set encoding of UTF-8. All well and good. However in a Cocoa app, I can't seem to find the equivalent for the UTF-8 part. This is a cross-platform app, but at this point I'll go with any solution... I've tried: NSLocale *loc = NSLocale.currentLocale; NSString *lang = loc.localeIdentifier; setlocale(LC_ALL, NULL); char *text = nl_langinfo(CODESET); if (text) NSString *charset = [NSString stringWithUTF8String:text]; NSLog(@lang:%@nchar:%@n,lang, charset); which displays: lang:en-GB char:US-ASCII Also tried: // Search for locale info by preferred environment variable NSProcessInfo *pi = NSProcessInfo.processInfo; NSDictionary *env = pi.environment; NSString *spec = env[@LC_ALL]; if (spec == nil) spec = env[@LC_CTYPE]; if (spec == nil) spec = env[@LANG]; NSLog(@spec:%@n, spec); which displays: spec:(null) Also tried: CFStr

I've encountered this exact same problem. I follow this guide to a tee: https://developer.apple.com/documentation/xcode/configuring-your-app-to-use-alternate-app-icons And yet I am consistently hit with: Failed: Error Domain=NSPOSIXErrorDomain Code=35 Resource temporarily unavailable UserInfo={_LSFile=LSIconAlertManager.m, _LSLine=113, _LSFunction=-[LSIconAlertManager iconChangeAlertTokenForIdentity:error:]} My app targets iPads and iPhones, has a minimum version for iOS of 18, and I am not using a simulator, I am running on my own device (iPhone 17 on iOS 26.2). This has been driving me insane. The example project Apple provides works, so I cannot see what possibly could be different.

The sandbox-relaxed mode works up to 26.1 and stopped working in 26.2. So, with a bit more digging, I was able to figure out what's going on here. Basically, as part of a security fix (r.157744252) in macOS 26.2, CUPS was changed to use a fixed configuration, by its config file (/etc/cups/cups-files.conf). That's actually what explains this: As an alternative to the relaxed mode, we also tried Sandboxing off, but that doesn't help either (from CUPS scheduler/conf.h). ...as CUPS was actually always running at CUPSD_SANDBOXING_STRICT, regardless of how you configured it. Is there anything we can configure or modify in the system to achieve the old behaviour of sandbox-relaxed mode? If for some reason, we can’t get back to the previous sandbox-relaxed behaviour, is there a way for us to switch off the sandbox? No, I don't think so. The core problem here is that the sandbox configuration itself hasn't actually changed; cupsd is just ignoring any configuration file. I think you can see this directly if you try pas

Why not just have a way to allow the user to buy the IAP without having to play for 5 minutes? If there's some sort of menu screen just add a way of buying the IAP from there. Some users might play your game for two minutes ten times and never see the screen that appears after five minutes, but they might like it enough to buy it. One of my apps lets you add three things in the free version, and unlimited things once you've bought the IAP, but you don't have to add exactly three things before the buy button appears; it's always there.

Do you guys know how to fix the render of the text in the accessory view ? If I force the color of text to be .black it work but it will break dark mode, but forcing it .black : .white on color scheme changes makes white to still adapt to what is behind it I have noticed that Apple Music doesn’t have that artifact and it seems to break when images are behind the accessory view // MARK: - Next Routine Accessory @available(iOS 26.0, *) struct NetxRoutinesAccessory: View { @ObservedObject private var viewModel = RoutineProgressViewModel.shared @EnvironmentObject var colorSchemeManager: ColorSchemeManager @EnvironmentObject var routineStore: RoutineStore @EnvironmentObject var freemiumKit: FreemiumKit @ObservedObject var petsStore = PetsStore.shared @Environment(.colorScheme) private var colorScheme // Tab accessory placement environment @Environment(.tabViewBottomAccessoryPlacement) private var accessoryPlacement // Navigation callback var onTap: (() -> Void)? @State private var isButtonPressed = false /// Ex
