Hi, I have an existing AppKit-based Mac app that I have been working on for a few years. For a new feature, I wanted to have the app opened by a different app, so I setup the URL scheme under CFBundleURLTypes in my Info.plist, and adopted this delegate callback:   - (void)application: (NSApplication *)application openURLs:(nonnull NSArray<NSURL *> *)urls Now when I invoke the URL from the 2nd app, it opens my app correctly, BUT this delegate method isn't called. What's interesting is that if I make a totally new app with a URL scheme and adopt this delegate method, it gets called without a problem! SO what about my original project could be responsible for this 'opensURLs' method to not be called? I've been searching for a solution for a couple of days without any luck. The macOS app's target has a Deployment Target of 10.15 and I'm running this on macOS12.0 with Xcode 13.

Hi, I'm trying to make a weather menu bar app, and I want to have it so that the icon of the app in the menu changes with the actual weather, but the icon isn't showing up. There is still a space in the menu bar where I can click and open the app, it's just that the icon has disappeared. Any ideas to fix it?

I have a NSRulerView with a vertical orientation. It works fine from macOS 10.13 to 11.x. In macOS Monterey (12.2.1 here), the ruler view is not receiving drawHashMarksAndLabelsInRect: messages when the associated NSTextView is scrolled vertically. When the parent NSScrollView is resized, the ruler view is correctly refreshed on all macOS versions. [Q] Is it a known bug in macOS Monterey?

In Monterey, when a user was at the top of a ScrollView implemented inside of a NSHostingController's view (that was itself embedded in a window with a NSToolbar), the window's toolbar background would be hidden until the user scrolled from the top. In Ventura, this behavior is different, with the toolbar's background visible all of the time unless a traditional NSScrollView is used (which means no SwiftUI). Is there the ability to change this behavior within SwiftUI some how now?

Is there any way to get dock size? I got Dock Window using CGWindowListCopyWindowInfo. But I found its frame covers my entire screen. Same promble as Notification Center. Any way to get their size?

When using the new ‘addSymbolEffect’ effect method on NSImageView with the ‘.rotate.byLayer’ parameter with an applicable SF Symbol 6 symbol, the resulting animation is not completely as expected, to say it mildly. This is the code line I use: imageView.addSymbolEffect(.rotate.byLayer, options: .repeat(.continuous), animated: true) The correct layer rotates around the correct anchor point, but the whole image is moving up and down. The same code with the same symbol in iOS 18 beta runs perfectly. Does anyone know how to get this new rotate API correctly working in macOS 15 beta? In case an Apple engineer reads this: FB13916874 contains example projects for macOS (wobbling rotation) and iOS (perfect rotation), and a screen recording what I see in macOS 15 beta.

In the recent MacOS Sequoia Beta 3 NSTextAttachment initialized with custom data and an Image cell as attachmentCell are shown as a file icon istead of the image cell. I am creating a NSAttributedString and showing it in NSTextView like this: NSTextAttachment *attachment = [[NSTextAttachment alloc] initWithData:[text dataUsingEncoding:NSUTF8StringEncoding] ofType:nil]; attachment.attachmentCell = [[NSTextAttachmentCell alloc] initImageCell:img]; NSMutableAttributedString *res = [[NSMutableAttributedString alloc] initWithAttributedString:[NSAttributedString attributedStringWithAttachment:attachment]]; ...

Hello, I want to subclass NSDocumentController, but I could not find the information in Apple document how to subclass. According to ChatGPT, it can be instantiated by [MyDocumentController sharedDocumentController]; before NSApplicationMain() as the following code. It seems working well in my test environment. int main(int argc, const char * argv[]) { [MyDocumentController sharedDocumentController]; NSApplicationMain(argc, argv); } But, I am not sure whether it is officially correct to instantiate so early (before calling NSApplicationMain). Is there any official information what is correct way to instantiate subclass of NSDocumentController?

I have a SwiftUI View containing a PDFView from PDFKit (via NSViewRepresentable). When setting a new PDFDocument the view flashes briefly with the background color before displaying the new document. Curiously the flashing is vastly reduced (but not eliminated) by calling layoutDocumentView() which should already be called from setDocument according to its documentation. struct SheetView: NSViewRepresentable { var pdf: PDFDocument? func makeNSView(context: Context) -> PDFView { let pdfView = PDFView() pdfView.displaysPageBreaks = false pdfView.displayMode = .singlePage pdfView.pageShadowsEnabled = false pdfView.autoScales = true return pdfView } func updateNSView(_ pdfView: PDFView, context: Context) { if pdf != pdfView.document { pdfView.document = pdf pdfView.layoutDocumentView() // reduces flashing but does not eliminate it } } }

I created a simple application which displays a window with a sample text and I'm supposed to use an alert when the user chooses to close the application, if he presses ok in the alert the application will close, if he presses cancel it goes on. So pretty simple code, I have a window class: // // MyWindow.h // AppTest // // Created by sanya on 11/09/24. // #ifndef MyWindow_h #define MyWindow_h @interface Window : NSWindow { NSTextField* label; } - (instancetype)init; - (BOOL)windowShouldClose:(id)sender; @end @implementation Window -(instancetype)init { label = [[[NSTextField alloc] initWithFrame:NSMakeRect(5, 100, 290, 100)] autorelease]; [label setStringValue:@"Hello, World!"]; [label setBezeled:NO]; [label setDrawsBackground:NO]; [label setEditable:YES]; [label setSelectable:YES]; [label setTextColor:[NSColor colorWithSRGBRed:0.0 green:0.5 blue:0.0 alpha:1.0]]; [label setFont:[[NSFontManager sharedFontManager] convertFont:[[NSFontManager sharedFontManager] convertFont:[NSFont fontWithName:[[label font] fontName] size:45] toHaveTrait:NSFontBoldTrait] toHaveTrait:NSFontItalicTrait]]; [super initWithContentRect:NSMakeRect(0, 0, 300, 300) styleMask:NSWindowStyleMaskTitled | NSWindowStyleMaskClosable | NSWindowStyleMaskMiniaturizable | NSWindowStyleMaskResizable backing:NSBackingStoreBuffered defer:NO]; [self setTitle:@"Hello world (label)"]; [[self contentView] addSubview:label]; [self center]; [self setIsVisible:YES]; return self; } - (BOOL)windowShouldClose:(id)sender { BOOL bClose = NO; CFOptionFlags responseFlags = 0; // Display the alert CFUserNotificationDisplayAlert( 0, kCFUserNotificationNoteAlertLevel, NULL, NULL, NULL, CFSTR("Alert Title"), CFSTR("This is a message displayed in the alert."), CFSTR("OK"), CFSTR("Cancel"), NULL, &responseFlags ); if (responseFlags == kCFUserNotificationDefaultResponse) { NSLog(@"User clicked OK"); bClose = YES; } else if (responseFlags == kCFUserNotificationAlternateResponse) { NSLog(@"User clicked Cancel"); } if( bClose ) [NSApp terminate:sender]; return bClose; } @end #endif /* MyWindow_h */ And in the main function I just initialize it: int main(int argc, const char * argv[]) { [NSApplication sharedApplication]; [[[[Window alloc] init] autorelease] makeMainWindow]; [NSApp run]; } It seems to work but if click 'Cancel' on the dialog , xcode gives me the following warning: CLIENT ERROR: TUINSRemoteViewController does not override -viewServiceDidTerminateWithError: and thus cannot react to catastrophic errors beyond logging them So i'm obviously not doing this in the correct way, how can I fix this? Also, any feedback on this code as a whole is highly appreciated.

I'm using NSTextTable to format panels of stand-out text within body text. Paragraphs within the panel are handled as individual NSTextTableBlocks within the table. Each block is added to the NSMutableParagraphStyle that is part of the attributed string within the block's attributes. That's all fine and it works. But... Occasionally I see undrawn lines within the panel. These disappear (or sometimes appear) when the parent window (and thus the NSTextView holding the rendered attributed string) is resized. Lines do not always appear, and when they do they are not always in the same place. The height of the gap varies. I see this behaviour with these panels and with tables. What's common to both cases is not only the use of NSTextTable and NSTextTableBlock etc., but crucially (I think) the use of block margins. If I disable margins (which looks OK for the panels, but isn't right for tables), the problem disappears. So, a bug or (more likely) I'm missing a key part of view rendering or margin set up. But what? Code here: https://github.com/smittytone/PreviewMarkdown/blob/930f5f32aa0b3b77ec3f4f53436a79e10bb26f18/Markdown%20Previewer/Styler.swift#L882 Running 14.6.1 on an M3. I'm using TextKit 1 because I'm using an NSLayoutManager subclass to override certain text underlines (not used in panels as outlined above, or tables).

The performance of the PrintCore API on macOS Sequoia system has significantly deteriorated. When switching between page options in the print dialog, the application hangs. It can be observed through Instruments that the execution time of PrintCore() is higher on the Sequoia system than on the Sonoma system. 479.00 ms 17.0% 0 s PMBaseObject::PMBaseObject(char const*) 456.00 ms 16.2% 0 s PMBaseObject::~PMBaseObject()

So I have this program that displays events on the window using NSWindow and a NSTextField. Basically it tracks the mouse position and the keyboard state. I created a simple class named MyEventWindow: // // MyEventWindow.h // AppTest #ifndef MyEventWindow_h #define MyEventWindow_h @interface MyEventWindow : NSWindow { } @property(nonatomic, strong) NSTextField* label; @property(nonatomic, strong) NSString* labelText; - (BOOL)windowShouldClose:(id)sender; - (instancetype) init; - (void) setLabelText:(NSString *)labelText; @end @implementation MyEventWindow -(instancetype) init { self = [super initWithContentRect:NSMakeRect(100, 100, 300, 300) styleMask:(NSWindowStyleMaskTitled | NSWindowStyleMaskClosable | NSWindowStyleMaskMiniaturizable | NSWindowStyleMaskResizable) backing:NSBackingStoreBuffered defer:NO]; if( !self ) { return nil; } [self setTitle: @"Event tracker"]; [self setIsVisible: YES]; _label = [[NSTextField alloc] initWithFrame:NSMakeRect(5, 100, 290, 100)]; [_label setBezeled: NO]; [_label setDrawsBackground: NO]; [_label setEditable: NO]; [_label setSelectable: YES]; NSFont *currentFont = [_label font]; NSFont *resizedFont = [NSFont fontWithName:[currentFont fontName] size:18]; NSFont *boldFont = [[NSFontManager sharedFontManager] convertFont:resizedFont toHaveTrait:NSFontBoldTrait]; // convert the bold font to have the italic trait NSFont *boldItalicFont = [[NSFontManager sharedFontManager] convertFont:boldFont toHaveTrait:NSFontItalicTrait]; [_label setFont:boldItalicFont]; [_label setTextColor:[NSColor colorWithSRGBRed:0.0 green:0.5 blue:0.0 alpha:1.0]]; // attach label to the damn window [[self contentView] addSubview: _label]; return self; } -(BOOL)windowShouldClose:(id)sender { return YES; } -(void) setLabelText:(NSString *)newText { [_label setStringValue: newText]; } @end #endif /* MyEventWindow_h */ Then in the main file I try to handle event loop manually: // // main.m #import &lt;Cocoa/Cocoa.h&gt; #import "MyEventWindow.h" NSString* NSEventTypeToNSString(NSEventType eventType); NSString* NSEventModifierFlagsToNSString(NSEventModifierFlags modifierFlags); int main(int argc, char* argv[]) { @autoreleasepool { [NSApplication sharedApplication]; MyEventWindow* eventWindow = [[MyEventWindow alloc] init]; [eventWindow makeKeyAndOrderFront:nil]; NSString* log = [NSString string]; // my own message loop [NSApp finishLaunching]; while (true) { @autoreleasepool { NSEvent* event = [NSApp nextEventMatchingMask:NSEventMaskAny untilDate: [NSDate distantFuture] inMode:NSDefaultRunLoopMode dequeue:YES]; log = [NSString stringWithFormat:@"Event [type=%@ location={%d, %d} modifierFlags={%@}]", NSEventTypeToNSString([event type]), (int)[event locationInWindow].x, (int)[event locationInWindow].y, NSEventModifierFlagsToNSString([event modifierFlags])]; //NSLog(@"log: %@", log); [eventWindow setLabelText: log]; [NSApp sendEvent:event]; //[NSApp updateWindows]; // redundant? } } } return 0; } NSString* NSEventTypeToNSString(NSEventType eventType) { switch (eventType) { case NSEventTypeLeftMouseDown: return @"LeftMouseDown"; case NSEventTypeLeftMouseUp: return @"LeftMouseUp"; case NSEventTypeRightMouseDown: return @"RightMouseDown"; case NSEventTypeRightMouseUp: return @"RightMouseUp"; case NSEventTypeMouseMoved: return @"MouseMoved"; case NSEventTypeLeftMouseDragged: return @"LeftMouseDragged"; case NSEventTypeRightMouseDragged: return @"RightMouseDragged"; case NSEventTypeMouseEntered: return @"MouseEntered"; case NSEventTypeMouseExited: return @"MouseExited"; case NSEventTypeKeyDown: return @"KeyDown"; case NSEventTypeKeyUp: return @"KeyUp"; case NSEventTypeFlagsChanged: return @"FlagsChanged"; case NSEventTypeAppKitDefined: return @"AppKitDefined"; case NSEventTypeSystemDefined: return @"SystemDefined"; case NSEventTypeApplicationDefined: return @"ApplicationDefined"; case NSEventTypePeriodic: return @"Periodic"; case NSEventTypeCursorUpdate: return @"CursorUpdate"; case NSEventTypeScrollWheel: return @"ScrollWheel"; case NSEventTypeTabletPoint: return @"TabletPoint"; case NSEventTypeTabletProximity: return @"TabletProximity"; case NSEventTypeOtherMouseDown: return @"OtherMouseDown"; case NSEventTypeOtherMouseUp: return @"OtherMouseUp"; case NSEventTypeOtherMouseDragged: return @"OtherMouseDragged"; default: return [NSString stringWithFormat:@"%lu", eventType]; } } NSString* NSEventModifierFlagsToNSString(NSEventModifierFlags modifierFlags) { NSString* result = @""; if ((modifierFlags &amp; NSEventModifierFlagCapsLock) == NSEventModifierFlagCapsLock) result = [result stringByAppendingString:@"CapsLock, "]; if ((modifierFlags &amp; NSEventModifierFlagShift) == NSEventModifierFlagShift) result = [result stringByAppendingString:@"NShift, "]; if ((modifierFlags &amp; NSEventModifierFlagControl) == NSEventModifierFlagControl) result = [result stringByAppendingString:@"Control, "]; if ((modifierFlags &amp; NSEventModifierFlagOption) == NSEventModifierFlagOption) result = [result stringByAppendingString:@"Option, "]; if ((modifierFlags &amp; NSEventModifierFlagCommand) == NSEventModifierFlagCommand) result = [result stringByAppendingString:@"Command, "]; if ((modifierFlags &amp; NSEventModifierFlagNumericPad) == NSEventModifierFlagNumericPad) result = [result stringByAppendingString:@"NumericPad, "]; if ((modifierFlags &amp; NSEventModifierFlagHelp) == NSEventModifierFlagHelp) result = [result stringByAppendingString:@"Help, "]; if ((modifierFlags &amp; NSEventModifierFlagFunction) == NSEventModifierFlagFunction) result = [result stringByAppendingString:@"Function, "]; return result; } in main I added a second @autoreleasepool inside the while loop it seemed to decrease memory usage significanly, however if I keep moving my mouse a lot the memory usage will still increase. I don't think this should be happening since the labelText is being destroying and recreated each iteration, is something wrong with my code? Why do I have a memory leak here? Any feedback regarding the code is also appreciated Cheers

I have an application with storyboard and I'm trying to set a constraint for the minimum size of my window (the view), but now matter what I do the constraint window is always grayed out, how do I go about this?

I have created a NSView inside the NSWindow. I m trying to identify when the view gets clicked by the user. For this I m using NSClickGestureRecognizer, but the registered method is not getting invoked. I have tried adding this for other widgets like button but it does not work either. Am I missing something? class SelectionList :NSObject, NSTextFieldDelegate{ let containerView = NSView() func createSelectionList (pWindow: NSWindow) { // created container View ... let clickRecognizer = NSClickGestureRecognizer() clickRecognizer.target = self clickRecognizer.buttonMask = 0x2 // right button clickRecognizer.numberOfClicksRequired = 1 clickRecognizer.action = #selector(ClickGestured) containerView .addGestureRecognizer(clickRecognizer) } @objc func clickRecognizer() { print("clicked") } }

In the WWDC22 talk "What's new in TextKit and text views" (https://developer.apple.com/videos/play/wwdc2022/10090?time=408), it was announced (at minute 6:45) that TextKit 2 & NSTextList is supposed to be working on both UIKit and AppKit. While NSTextLists are correctly rendering on iOS, they are not working on macOS. The paragraphs aren't inset and the numbers/bullets do not render in front of the list items. Any help? let textView = NSTextView(frame: self.view.bounds) textView.translatesAutoresizingMaskIntoConstraints = false self.view.addSubview(textView) let safeArea = view.safeAreaLayoutGuide NSLayoutConstraint.activate([ textView.topAnchor.constraint(equalTo: safeArea.topAnchor), textView.bottomAnchor.constraint(equalTo: safeArea.bottomAnchor), textView.leadingAnchor.constraint(equalTo: safeArea.leadingAnchor), textView.trailingAnchor.constraint(equalTo: safeArea.trailingAnchor) ]) let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.textLists = [NSTextList(markerFormat: NSTextList.MarkerFormat("{decimal}."), options: 0)] let attributedText = NSMutableAttributedString("Item 1\nItem 2\nItem 3\nItem 4f") attributedText.addAttribute(.paragraphStyle, value: paragraphStyle, range: NSRange(location: 0, length: attributedText.length)) textView.textStorage?.setAttributedString(attributedText)

We have a xib file that contains a toolbar with some items in it. The toolbar has an IBOutlet defined in its files owner. Before macOS 15 - we were able to reach the items in the toolbar by using the items property. The File Owner for the xib containing the toolbar is a NSViewController e.g. @IBOutlet var theToolbar: NSToolbar! required init?(coder: NSCoder) { super.init(coder: coder) Bundle.main.loadNibNamed("ToolbarDesign", owner: self, topLevelObjects:nil) } and then later in code... func getItems() { let items:[NSToolbarItem]? = mainRightToolbar?.items } Prior to macOS15 - items would contain the NSToolbarItems specified in the xib design. Now, in macOS 15 - the items array is not nil but doesn't contain any items either. What needs to be don't for macOS15 specifically to enable the items property of NSToolbar to work again?

I have a simple cocoa project, it has the default files like AppDelegate.m, AppDelegate.h , ViewController.h and ViewController.m what I want is to set the Window title to the dimension of the current window and update it as the user resizes it. My Storyboard has an Application Scene, a Window Controller Scene and a test Scene which contains my view: how do I go about this? should my ViewController or AppController implement NSWindowDelegate ?
