Hi there, My macOS AppKit/Cocoa app uses Swift and Objective-C, however I'm not using SwiftUI anywhere. Customers launching the app now receive an instant crash due to dyld not being able to locate SwiftUI: Library not loaded: /System/Library/Frameworks/SwiftUI.framework/Versions/A/SwiftUI Again, not using SwiftUI anywhere in my app, cannot find any project references in Xcode that mention SwiftUI - yet checking the generated binary with otool reveals that my app indeed appears to link against SwiftUI. Any idea what happened..? Thanks, Jay

When running my app from Xcode Umlauts are all of a sudden broken in several places. The app has been out in the public w/o similar issues for years. For example, this is the result when entering a filename in my NSDocument-based app: So far I could only observe the bug when launching under Sonoma from Xcode but I'm worried this might be a general issue for users of the app running the release build. Any ideas about what happened in macOS 14.4..? Cheers, Jay

Hi there - Where would a dev go these days to get an initial understanding of SceneKit? The WWDC videos linked in various places seem to be gone?! For example, the SceneKit page at developer.apple.com lists features a session videos link that comes up without any result, https://developer.apple.com/scenekit/ Any advice..? Cheers, Jan

After upgrading to Xcode 15.3 (15E204a) trivial C++ code of mine no longer compiles: const string text = textComponent->GetText(); auto isEmpty = text.empty() || std::all_of(text.begin(), text.end(), std::isspace); now yields compiler error "No matching function for call to 'all_of'" while working as expected on Version 15.2 (15C500b) and older. Is there a regression in the latest Xcode update C++ support..? Thanks, Jay

So in my app users can select a larger block of connected elements with a triple-click, just like selecting a paragraph works in an NSTextView. However, a small subset of these elements also has properties that can be edited and a double-click switches to edit mode for these elements.. This leads to the current, unfortunate behaviour: If a user triple-clicks a non-editable element the entire block of elements is highlighted, no problem. If a user triple-clicks editable elements an edit is triggered and the third click is ignored. What would be the best approach to enable triple-click on editable elements, i.e. something like waiting whether a third mouse click follows and enabling edit mode only then..? Some dispatch after mechanism with a delay of NSEvent.doubleClickInterval maybe? Any suggestions on how to implement this in a robust manner would be much appreciated! Cheers, Jay

I'd like to build an XCFramework and the consuming app in a single workspace to make sure the latest version of the framework is bundled with the app. So both projects - framework and app - are bundled in a common workspace in Xcode; just as we are used to with regular frameworks. In the framework's project I'm creating the XCFramework as per Apple's instruction as a script-only target using xcodebuild -create-xcframework to bundle the individual framework binaries. Now I'd like to include the generated .xcframework in the app project. However, Xcode doesn’t seem to understand that the framework project target creating the XCFramework is actually creating output: I’ve added the XCFramework target as a dependency in the consuming project, it builds when the main project is built, but there’s no output to be selected in the Link with Libraries or Copy Frameworks steps of the app project Directly adding the framework via Finder as a folder from either Debug/Release folder doesn't make sense, which one would you pick? This is a trivial step for regular frameworks but apparently I'm overlooking something when dealing with the .xcframework. How to proceed? Thanks, Jay

My framework project is bundled in the ‘consuming’ project inside 1 workspace in Xcode. Creating the XCFramework as per Apple's instruction as a script-only target using xcodebuild -create-xcframework to bundle the individual framework binaries works just fine; However, Xcode doesn’t seem to understand that the target creating the XCFramework is actually creating output: I’ve added the XCFramework target as a dependency in the consuming project, it builds when the main project is built, but there’s no output that can be selected in the Link with Libraries or Copy Frameworks steps under Build Phases; just the regular frameworks show up, not my newly built XCFramework. Directly adding the framework via Finder as a folder from the built products folder breaks easily.. How can I tell my main project to include the XCFramework that it just build as a dependency? That is, like we do for any other framework in the same workspace. Thanks, Jay

Hi there, So according to Apple's recent Apple announces biggest upgrade to App Store pricing announcement "These newly announced tools, which will begin rolling out today and continue throughout 2023..." (https://developer.apple.com/news/?id=qzex35ch) Yet I don't seem to find a way to set individual, country-specific prices for my products. Anybody having more luck..? Cheers, Jay

The orientation property in NSPrintInfo does not reflect the current user choice (Landscape/Portrait), at least not while the Print Panel is presented. How can we determine the paper orientation? Thanks, Jay

Is there a built-in functionality to retrieve the current column and row during a print operation when using the built-in pagination mechanism of NSView? All I could find in the general printing documentation and for the NSPrintOperation and NSPrintInfo classes is the NSPrintOperation.currentOperation.currentPage property. I'm basically attempting to access the 'address' (page number or row/column) of pages bordering to the left/right/above/below the current page to enable assembly constructions being shown to the user on printouts spanning multiple pages. Hope this makes sense. Thanks, Jay

Hi there, the Mac App Store updater crashes my apps as it's updating apps while they're running. Lazy loaded .xib's from the newer version don't match the code of the previous version that's already loaded in memory - so the app crashes. How can this be prevented? Cheers, Jay

Hi there,we are getting frequent questions from our user base when they cannot find options in the print dialog of our app because the details in NSPrintPanel are not expanded by default.Is there a way to always expand the details section programmatically to make it easier for our non-technical user base to find the app specific print settings..?Browsing the NSPrintPanel documentation didn't reveal anything obvious..Cheers,Jay

I have an iOS project that was created a couple Xcode versions ago bundling some XCFrameworks. As of recently (still with Xcode 13.4.1 (13F100)) the app won't launch anymore on actual devices with the dreaded Unable to install "XYZ" error. I have several other projects using one or other of the XCFrameworks, all using the same team and code signing options, and in any of the other apps still work fine on my test device. I've compared settings between the apps that launch and the one that doesn't but I can't spot any difference that could cause an issue.. Is there any way to track down the specific problem with this app? This is the detailed output when launching on device fails: Unable to install "XYZ" Domain: com.apple.dt.MobileDeviceErrorDomain Code: -402620375 User Info: { DVTErrorCreationDateKey = "2022-06-10 12:22:19 +0000"; IDERunOperationFailingWorker = IDEInstalliPhoneLauncher; } -- The code signature version is no longer supported.

We are using lots of toolbar items with templated NSImage instances in our app. Especially for things like the currently selected tool from a set of tools the extremely low contrast style employed by macOS 11 is a huge usability issue.. Before macOS 11 selected items were rendered in a high-contrast, inverted style. Is there any way to control the style used to render selected toolbar items to restore usability? Cheers, Jay
