I have had this issue for a long time. If I configure any auto layout constraints in TableViewCell, I get extremely weird layout behavior in IB designer; however, layout is completely good during runtime.
For example, with a completely new project and a single NSTableView on the main view, I get:
If I resize main view, the tableview won't get resized
Every time I reopen the project, the tableview would shrink by height.
It seems the shrinked height is doubled every time. For example, in the following screenshot, the gap is 56. Next reopen will double the gap to 112.
Is this a known bug? I would want to file bug report at https://feedbackassistant.apple.com.

Hello,
here is the block where arrayController is nil :
{
NSData * data;
NSError * error;
Class klass;
if(_arrayController != nil) // nil !
{
selected = [_arrayController selectedObjects];
arranged = [_arrayController arrangedObjects];
if([selected count] > 0)
{
_currentObject = [selected objectAtIndex:0];
if(_currentObject != nil)
{
data = [_currentObject valueForKey:kVrRoot];
klass = [NSMutableDictionary class];
_vrRoot =
[NSKeyedUnarchiver unarchivedObjectOfClass:klass fromData:data error:&error];
}else
{
_vrRoot = [NSMutableDictionary new];
data = [NSKeyedArchiver archivedDataWithRootObject:_vrRoot requiringSecureCoding:YES error:&error];
}
}
}
}
I use this for years so I don't no what's wrong.
Xcode contains several crash reports downloaded from users of my app. Thread 0 apparently crashes at [CATransaction(NSCATransaction) NS_setFlushesWithDisplayLink], but there's not a single stacktrace line that contains code within my app, so I have no idea what this means or how to reproduce it.
What could cause such a crash?

Xcode contains several crash reports downloaded from users of my app. Thread 0 apparently crashes after calling NSApp.runModalForWindow(_:) (within the redacted stacktrace rows 17-19 that are locations in my own code). All the other threads only contain calls to system code.
What could cause such a crash?

My app (AppKit, not SwiftUI) displays a small utility window. I can place it over the menu bar, or in the area beside the notch on my MacBook Pro (when it is a secondary screen), but if the screen goes to sleep and I wake it, macOS has moved the window off the menu bar or down out of the notch area.
Is there any way to indicate a window should never be moved by the OS?
I have a doc, xib based project.
it has an NSCollectionView, which properly displays the data. including items and section headers.
I have drag n drop enabled where I can drop into the collectionView, and I generate a new object. this is NOT a reordering issue (yet)
when I drop into the collectionView, if the drop is on top of a HeaderView, the drop is canceled (before it gets to my delegate code.) But more importantly : the Header views are entirely ignored in every step of the drag and drop. the hinting, only ever shows up adjacent to a collectionViewItemView, Never below or above the section header. The drop ALWAYS has a section of zero in its index path. regardless of where the drop is.
I tried to override this behavior in both the validate drop and accept drop methods. with a great deal of frustration and struggle I discovered that I cannot compare the placement of my header views, because the frames of those views are all at the base origin point.
is this normal behavior? Has anyone else run into this? is there a fix?
I have a macOS app made with the Electron framework. Ever since I updated to macOS Sonoma, I've been facing a random crash whenever I click on the app menu/apple menu. This is not reproducible but happens quite often. On checking the crash report, I can notice that nil is being provided as an input to __NSPlaceholderDictionary initWithObjects method, but this crash does not happen in macOS Ventura or older versions. Is this due to any new validation added to the above method in macOS Sonoma ?

I have an Objective-C App that has worked perfectly until Monterey was released. The app is activated and displays a window when it’s hotkey is typed. The problem is that—starting in Monterey—if the cursor is in an html Password field of ANY website in ANY browser, the app’s window does not display. After many many hours of debugging, I have determined that the problem is that in this case, [NSApp activateIgnoringOtherApps:YES] never activates the app, and that [myWindow makeKeyAndOrderFront:nil] does nothing. In this case, if I display a window using [NSApp runModalForWindow:myWindow], the window does display, but is not key until it is clicked, at which point the app activates.
Note that everything works properly with the cursor in any browser field other than a Password field, or in any other app. It also works with the cursor anywhere in MacOS versions 10.12 through 11.
Is this is some kind of new security feature? Is this a bug or is there a workaround for this? I there a low-level non-Cocoa way to activate an app?
Hi,
I'm trying to drag an NSTextView from one NSView to another. I'm getting the right events, but the drag animation is not coming up.
Subclassed TextView:
class MyTextView:NSTextView, NSPasteboardItemDataProvider
{
func pasteboard(_ pasteboard: NSPasteboard?, item: NSPasteboardItem, provideDataForType type: NSPasteboard.PasteboardType)
{
NSLog ("Paste")
}
override func mouseDown(with theEvent: NSEvent)
{
let pasteboardItem = NSPasteboardItem()
pasteboardItem.setDataProvider(self, forTypes: [.string])
let draggingItem = NSDraggingItem(pasteboardWriter: pasteboardItem)
draggingItem.setDraggingFrame(self.bounds, contents:.Publisher)
beginDraggingSession(with: [draggingItem], event: theEvent, source: self)
}
override func draggingUpdated(_ sender: NSDraggingInfo) -> NSDragOperation
{
return NSDragOperation.copy
}
}
Subclassed NSView to receive the drop event:
class DropView:NSView
{
func EnableDrop ()
{
// Registering for drag drop types
registerForDraggedTypes([NSPasteboard.PasteboardType.string, NSPasteboard.PasteboardType.URL, NSPasteboard.PasteboardType.multipleTextSelection, NSPasteboard.PasteboardType.color])
}
func shouldAllowDrag(_ draggingInfo: NSDraggingInfo) -> Bool
{
return true
}
override func draggingEntered(_ sender: NSDraggingInfo) -> NSDragOperation {
// To show a copy tooltip during drop
return NSDragOperation.copy
}
override func prepareForDragOperation(_ sender: NSDraggingInfo) -> Bool
{
return true
}
override func performDragOperation(_ draggingInfo: NSDraggingInfo) -> Bool {
let draggedview = draggingInfo.draggingSource as! NSView
NSLog ("Drop received")
return true
}
}
When I create my view in the ViewController, I do "myviewobj.EnableDrop()" to receive drop events. However as stated above, I'm not able to see the drag animation happening, however, I do get events for it.
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!
I tried to load font using CTFontCreateWithFontDescriptor() and it behaves differently than loaded using NSFont(). Let's say the goal is to load font using CoreText that is exactly the same as using AppKit.
NSTextField
If I use them in NSTextField text offsets and rendering do not match.
let familyName = "Helvetica"
let fontSize: CGFloat = 30
let string = "Hello, World! gÖ,|#"
// Load font using AppKit
let font1 = NSFont(name: familyName, size: fontSize)!
// Load font using CoreText API
let font2 = CTFontCreateWithFontDescriptor(CTFontDescriptorCreateWithAttributes([
kCTFontFamilyNameAttribute: familyName,
kCTFontSizeAttribute: fontSize,
] as [CFString : Any] as CFDictionary), 0, nil) as NSFont
// Setup text fields
let field1 = NSTextField()
let field2 = NSTextField()
field1.setAsLabel()
field2.setAsLabel()
field1.font = font1
field2.font = font2
field1.stringValue = string
field2.stringValue = string
NSAttributedString
If I use them in NSAttributedString bounding box height of text is different:
let bounds1 = NSAttributedString(string: string, attributes: [
.font: font1
]).boundingRect(with: .infinity)
let bounds2 = NSAttributedString(string: string, attributes: [
.font: font2
]).boundingRect(with: .infinity)
print(bounds1) // Prints: (0.0, -7.0, 252.3486328125, 37.0)
print(bounds2) // Prints: (0.0, -7.0, 252.3486328125, 31.0)
Investigation
I compared fonts, font attributes, traits, feature settings, even binary font tables but I didn't find any difference. It seems like there is something inside that alters behaviour.
I found that if I add .usesDeviceMetrics option to NSAttributedString bounds getter, it returns the same result but also completely different frame.
let bounds1 = NSAttributedString(string: "Hello, World! gÖ,|#", attributes: [.font: font1]).boundingRect(with: .infinity, options: [.usesDeviceMetrics])
let bounds2 = NSAttributedString(string: "Hello, World! gÖ,|#", attributes: [.font: font2]).boundingRect(with: .infinity, options: [.usesDeviceMetrics])
print(bounds1) // Prints: (2.3583984375, -6.6357421875, 249.9609375, 33.837890625)
print(bounds2) // Prints: (2.3583984375, -6.6357421875, 249.9609375, 33.837890625)
Question
How to load a font using CoreText in a way that NSFont does?
Minor question: Why does NSTextField set it's frame origin to -2.0?
Just extensions I used in code above:
extension CGSize {
public static var infinity: Self {
.init(width: CGFloat.infinity, height: CGFloat.infinity)
}
}
extension NSTextField {
func setAsLabel() {
translatesAutoresizingMaskIntoConstraints = false
isBezeled = false

Apple deprecated launch service calls like LSCopyAllRoleHandlersForContentType, referring to -[NSWorkspace URLsForApplicationsToOpenContentType:] instead.
However all those new NSWorkspace methods do not have the crucial LSRolesMask the launch service calls have.
For example, I have code that looks up all alternative shells, and with LSCopyAllRoleHandlersForContentType I could simply provide LSRoleMask.shell to restrict the returned bundle identifiers to shells only.
This is not the first time Apple deprecates stuff without a proper replacement and I don't really get it.
Every OS update is basically a downgrade.
Or is there another way to replicate the old launch service call behavior?
Have you encountered an issue with AXUIElements where context menu notifications fail to trigger after adding an observer for kAXMenuItemSelectedNotification?
The notification seems to work perfectly when users utilize keyboard shortcuts to select menu items, but when they click with the mouse, the notification fails to trigger.
After adding a native Mac target (SwiftUI Multiplatform + AppKit) to an iOS app, I get this compiler error. Does this require moving off of XIBs entirely, or is there something else I can do to resolve this error?
hi, with my objc project after install ios17.1 all datepicker with time inside (date and time or only time) crash when i scroll hour or minutes, what can i do?

I allow users to choose a font to use throughout the app, then display text using that font in 3 different ways:
As the default body font of an HTML document displayed in a WKWebView.
Used to create an NSAttributedString then displayed in an NSTextField.
Used as the body font of a very small HTML document (2-3 lines), converted to NSAttributedString, then displayed in an NSTextField.
My code has been working fine for years, but starting with the release of Sonoma (macOS 14), any text that is converted from HTML to NSAttributedString displays as all "question marks in boxes" for each character. This happens when certain fonts are used. In particular I've seen it with Calibri, Candara, and SF Pro. Calibri and Candara are Microsoft fonts and I think are distributed with MS Office. SF Pro is an Apple font.
There could be others; I haven't done an exhaustive check. What I can tell you is that this has been working fine literally until a couple weeks ago when customers began installing macOS 14. If they go into my app and select a different font (such as Arial or Times New Roman) everything works fine. It is only certain fonts that don't work, and those fonts work when used as the body font of an HTML document in WKWebView and when used as the font for a new NSAttributedString. They just don't work if you make a little HTML document with the font selected as the body font, then convert to NSAttributedString.
Here's the code that worked up until macOS 14:
NSString *htmlString = @"<!DOCTYPE html>"
"<html>"
"<head>"
"<style>"
"body { font-family: 'Candara', serif; font-size: 14px; }"
"</style>"
"</head>"
"<body>"
"This won't display right."
"</body>"
"</html>";
NSData *htmlData = [htmlString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *options = @{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
NSCharacterEncodingDocumentAttribute: @(NSUTF8StringEncoding)};
NSError *error;
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithData:htmlData
options:options
documentAttributes:nil
error:&error];
Note the fallback of "serif" — that doesn't matter. you get all undefined characters and the fallback font is not used. It's as if the renderer really believes the font is usable, but it isn't.
I've run into a very strange bug on macOS Sonoma, and I'm guessing it's caused by TextKit 1/2 compatibility issues.
Whenever the caret is drawn on the last line of NSTextView, the anti-aliasing or drawing rect or something changes, causing the text in the current line fragment rect to wiggle up and down. See the example below:
(Note that in this image, I'm using custom caret drawing to test that if that would solve something — it didn't.)
The effect is more apparent on non-Retina displays, but still present on Retina screens as well. I'm using TextKit 1 because I'm maintaining compatibility with older systems, and can't move away just yet. The behavior can't be reproduced on any other OS than Sonoma.
My NSTextView is scaled using scaleUnitSquareToSize but no matter the scale, the issue seems to be present. Text view also has custom input attributes, which includes line height, but drawing doesn't appear to be affected by that.
Has anyone else encountered similar issues on Sonoma, and do you have any suggestions on how to proceed with debugging this?
Hello,
How do I make the Tab Bar appear in the toolbar using SwiftUI for macOS? Instead of a seperate tab and tool bar I want it to be unified.
I am looking for a design similar to the "Compact" safari tab option, as shown in this window:
Thanks in advance,

I am new to developing native Apple apps and must familiarize myself with the Apple development frameworks. I am starting to create a personal document-based Apple App that can run on iOS, iPadOS, and macOS. The document will contain the following: HTML, PDF, images, video, and audio files. So, I think the document format could be HTML.
I need the capability to read, edit (WYSIWYG Editor), save, and share documents with other users using the same app. The data is stored in the user's device and iCloud.
I need guidance about what Apple framework I should use to edit the documents using WYSIWYG editing principles.
I would really appreciate any recommendation you can provide.
Many thanks for considering my request.
Thank you so much for your attention and participation.
I have been getting crash reports from users of my Mac app on Sonoma 14.0 and 14.1 when typing into an NSTextView subclass. The crash logs I have show involvement of the spell-checking system - NSTestCheckingController, NSSpellChecker, and NSCorrectionPanel. The crash is because of an exception being thrown. The throwing method is either [NSString getParagraphStart:end:contentsEnd:forRange:] or [NSTextStorage ensureAttributesAreFixedInRange:].
I have not yet reproduced the crash. I have tried modifying the reference finding process to simply link every word, via NSStringEnumerationByWords.
The text view in question recognizes certain things in the entered text and adds hyperlinks to the text while the user is typing. It re-parses and re-adds the links on every key press (via overriding the didChangeText method), on a background thread.
From user reports, I have learned that:
The crash only occurs on macOS 14.0 and 14.1, not on previous versions
The call stack always involves the spell checker, and sometimes involves adding recognized links to the text storage (the call to DispatchQueue.main.async in the code below)
The crash stops happening if the user turns off the system spell checker in System Settings -> Keyboard -> Edit on an Input Source -> Correct Spelling Automatically switch
The crash does not happen when there are no links in the text view.
Here is the relevant code:
extension NSMutableAttributedString {
func batchUpdates(_ updates: () -> ()) {
self.beginEditing()
updates()
self.endEditing()
}
}
class MyTextView : NSTextView {
func didChangeText() {
super.didChangeText()
findReferences()
}
var parseToken: CancelationToken? = nil
let parseQueue = DispatchQueue(label: "com.myapp.ref_parser")
private func findReferences() {
guard let storage = self.textStorage else { return }
self.parseToken?.requestCancel()
let token = CancelationToken()
self.parseToken = token
let text = storage.string
self.parseQueue.async {
if token.cancelRequested { return }
let refs = RefParser.findReferences(inText: text, cancelationToken: token)
DispatchQueue.main.async {
if !token.cancelRequested {
storage.batchUpdates {
var linkRanges: [NSRange] = []
storage.enumerateAttribute(.link, in: NSRange(location: 0, length: storage.length)) { linkValue, linkRange, stop in
if let linkUrl = linkValue as? NSURL {
linkRanges.append(linkRange)
}
}
for rng in linkRanges {
storage.removeAttribute(.link, range: rng)
}
for r in refs {
storage.addAttribute(.link, value: r.url, range: r.range)
}
}
self.verseParseToken = nil
}
}
}
}
}
I've filed this as FB13306015 if any engineers see this. Can anyone
