A macOS privileged helper tool that uses SubProcess crashes on intel Macs (running macOS 13 - 15: unable to test on macOS 26 on intel) with the error that libswiftCompatibilitySpan.dylib cannot be loaded when built with XCode 26.3. The same helper tool works as expected with XCode 26.2. The helper is installed using SMAppService. When I remove the dependency for SubProcess, the crash no longer occurs (but important functionality is also disabled).

I've recently upgraded to the RC candidates of macOS 26 and Xcode 26. The app I'm building has a helper tool using SMAppService. When I run the app and helper tool in macOS 15 or macOS 26, all works as expected. When it runs on macOS 13 or 14, which previously worked. The helper now crashes on launch with the following reason: Termination Reason: CODESIGNING 4 Launch Constraint Violation I found this developer session which seems to address this, but the plist I've added doesn't seem to satisfy the constraint. https://developer.apple.com/videos/play/wwdc2023/10266/ Here are the contents of my new plist: Are there any gotchas here that I might be missing? Thanks!

I have been working on updating an old app that makes extensive use of Objective-C's NSTask. Now using Process in Swift, I'm trying to gather updates as the process runs, using readabilityHandler and availableData. However, my process tends to exit before all data has been read. I found this post entitled "Running a Child Process with Standard Input and Output" but it doesn't seem to address gathering output from long-running tasks. Is there a straightforward way to gather ongoing output from a long running task without it prematurely exiting?

In macOS 15.4 (24E5238a) and Xcode 16.2, the NSStatus images appear to be missing. To reproduce, add an NSImageView to a Nib or StoryBoard and set the default image to any of the NSStatus images: NSStatusAvailable, NSStatusPartiallyAvailable, etc. Instead of the expected Green, Yellow dots, no image is displayed. The same occurs when setting images programatically. Is the plan to remove these images, or is this just temporary?

We have recently added WidgetKit widgets to an existing product, and they've been working great on Macs using Big Sur and later. Recently, when installing a build on a Montery Mac, the widgets were no longer in Notification Center. After some trial and error, we discovered that if we build the project with Xcode 15.4, the widgets appear, but if we build with Xcode 16, the widgets vanish. This seems to happen on Macs running Big Sur or Monterey. The project is being built on Macs running Sonoma (both Apple Silicon and Intel). Is there a build setting in Xcode 16 that may have this effect?

I'm exploring using a handful of frameworks to share code between macOS apps. However, one of these frameworks needs privilege to function. The main app has a helper tool utilizing SMAppService. However, I can't work out if there's a feasible way to use that helper tool to support the framework dependency. Should I be creating a second helper tool for the framework instead? Or am I barking up the wrong tree? Thanks!

I have existing code in production that links against the mach-o library, and uses the following code: NSData *data = [NSData dataWithBytes: getsectiondata(&_mh_execute_header, "__TEXT", "__somePlist_plist", &len) length:len]; In order for this to compile with Sequoia Beta 4 and Xcode 16 beta 4, I have to replace _mh_execute_header with _mh_dylib_header. If I don't, the compiler raises the following error: ld: Undefined symbols: __mh_execute_header, referenced from: -[MyClass init] in MyClass.o clang: error: linker command failed with exit code 1 (use -v to see invocation) Any idea why the linking behavior might have changed? Should I file a bug? (I realize this is a C issue, not Objective-C - but didn't find a tag for that) Thanks!

I have a menu bar extra app that includes a sub-menu for lesser used functions. The sub menu implements .keyboardShortcut for a few of the menu items. When the app is first the active app, the keyboard shortcuts only produce a beep UNTIL the sub menu has been accessed. Once the sub-menu has loaded, the keyboard shortcuts work as expected. I should note that the MenuBarExtra is using the .window display mode, if that's important. The submenu appears with a button press within the MenuBarExtra. Is there a method to expose the keyboard shortcuts to the system before the view has loaded?

Branching from a previous post titled "Privileged daemon using SMAppService in macOS Sequoia," I have a privileged daemon using SMAppSerice that works in Sonoma and Ventura. In the previous OS versions, privilege is applied in System Settings: Login Items, Allow in the Background. Under macOS sequoia, the daemon appears by its bundle id instead of the parent app, and underneath it reads "Item from unidentified developer" and does not run, even when enabled. I'm wondering if additional steps are needed in the new OS to sign privileged daemons properly?

I have some existing code that registers a privileged daemon using SMAppService. In Ventura and Sonoma, the privileged item gets added to Login Items (allow to run in background), and must be toggled on to finish granting privileged access. In 15.0 Beta (24A5264n), the app doesn't show up in the Login Item list. Is there something I should be doing differently to use this framework in Sequoia?

I am attempting to install and utilize an agent using the new(ish) SMAppService API with an existing app. The agent appears to install (no error is returned), but when I try to start the agent from Terminal, I get the following in the launchd.log: 2024-04-22 09:57:27.469039 (gui/502/com.redacted.service.agent) : internal event: WILL_SPAWN, code = 0 2024-04-22 09:57:27.469080 (gui/502/com.redacted.service.agent) : service state: spawn scheduled 2024-04-22 09:57:27.469081 (gui/502/com.redacted.service.agent) : service state: spawning 2024-04-22 09:57:27.469100 (gui/502/com.redacted.service.agent) : launching: one-shot 2024-04-22 09:57:27.469105 (gui/502/com.redacted.service.agent) : Allowing non-reentrant proxy for resolving path 2024-04-22 09:57:27.469947 (gui/502/com.redacted.service.agent [71866]) : xpcproxy spawned with pid 71866 2024-04-22 09:57:27.469960 (gui/502/com.redacted.service.agent [71866]) : internal event: SPAWNED, code = 0 2024-04-22 09:57:27.469964 (gui/502/com.redacted.service.agent [71866]) : service state: xpcproxy 2024-04-22 09:57:27.469997 (gui/502/com.redacted.service.agent [71866]) : internal event: SOURCE_ATTACH, code = 0 2024-04-22 09:57:27.506283 (gui/502/com.redacted.service.agent [71866]) : Service could not initialize: posix_spawn(/Users/chrisf/Library/Developer/Xcode/DerivedData/Redacted-gttupgdyakodzddurpavhmscwabs/Build/Products/Debug/Redacted App.app/Contents/MacOS/Service Agent.app), error 0xd - Permission denied 2024-04-22 09:57:27.506306 (gui/502/com.redacted.service.agent [71866]) : initialization failure: 23E224: xpcproxy + 31420 [1098][A7EF179C-FBCC-349E-A7D2-09B2F1408413]: 0xd 2024-04-22 09:57:27.506309 (gui/502/com.redacted.service.agent [71866]) : internal event: INIT, code = 13 2024-04-22 09:57:27.506313 (gui/502/com.redacted.service.agent [71866]) : job state = spawn failed 2024-04-22 09:57:27.507148 (gui/502/com.redacted.service.agent [71866]) : xpcproxy exited due to exit(78) 2024-04-22 09:57:27.507153 (gui/502/com.redacted.service.agent [71866]) : exited due to exit(78) 2024-04-22 09:57:27.507162 (gui/502/com.redacted.service.agent [71866]) : already handled failed init, ignoring 2024-04-22 09:57:27.507170 (gui/502/com.redacted.service.agent [71866]) : service state: exited 2024-04-22 09:57:27.507186 (gui/502/com.redacted.service.agent [71866]) : internal event: EXITED, code = 0 (tldr: error 0xd - Permission denied) I'd also be curious how we are expected to launch agents once registered with SMAppService. Is it sufficient simply to make an XPC call to an exposed method? Thanks!

I'm manually placing a subclass of NSView into the parent view using addSubview:positioned:relativeTo. The dirtyRect passed to drawRect: is wildly incorrect. Can folks attempt to reproduce and file bugs? This is awfully close to the release of Sonoma, and I feel like folks with bezier curves (or maybe other drawing code?) in their NSView subclasses are going to experience problems. To reproduce, place a view (I'm using an NSImageView) as a subview within a view. Then, create a subclass of NSView and draw a bezier curve in the drawRect method. Add an instance of this subclass as a subview of your original view. I'm offsetting the x value for clarity. When I build with Xcode 15 and run on Ventura or earlier, I get the correct result. Or, if I build with Xcode 14.3 and run on Sonoma I get the correct result. However, when I build in Xcode 15 and run on the RC build of Sonoma, I get a whacky result. I get something like (origin = (x = -264, y = -146), size = (width = 480, height = 388)) for the dirtyRect in the error case, while the rect is supposed to be (origin = (x = 0, y = 0), size = (width = 48, height = 48)) (I'm basing the frame of the new view on the original image.) Thanks!

I'm drawing a colored gradient inside a rectangular Bezier curve within a custom View's drawRect method using drawInBezierPath. When I convert the view to a PDF using drawInBezierPath, the gradient is replaced with gray. Is this a bug, or am I doing something wrong? Thanks!

My widget seems stuck in time. Regardless of what changes I make to the widget, they are not reflected in the simulator. Further, I've placed a breakpoint in getTimeline(in, completion) and it isn't getting called. Any ideas?

I'm building a menuBarExtra app for macOS, and I want to make a Quit menu available from a sub menu in the menuBarExtra, because the main window may be closed. When I try to add .keyboardShorcut("q") to the Button within Menu{}, the shortcut doesn't display, presumably because it's taken by the Quit menu item in the Application Menu. Any way to tell SwiftUI that they're doing the same thing so it will share the keyboard shortcut?
