Since recently (maybe after updating to Sonoma 14.7.1 - 23H222, but not sure, I get a crash report stating that SafariBookmarksSyncAgent quitted unexpectedly Once acquitted the report, it will reappear 2 minutes later as long as Xcode is open.
Configuration:
Sonoma 14.7.1
Safari Technology Preview Release 208 (Safari 18.2, WebKit 19621.1.5.1)
Xcode 15.3 (15E204a)
That seems to be a known problem.
Question: Is it due to MacOS version ? To Xcode version ? To Safari version ? To webKit version ? Or to simulator, as I gat an AegirPoster crash (as described here: https://stackoverflow.com/questions/77083912/macbook-pro-crashes-when-using-simulator-aegirposter-process)
I read that I would need to restart some devices (eg, iPhone). That seems to temporarily solve the problem

Apparently, settings do not show anymore the apps settings in iOS 18.2.
I tested on simulators (Xcode 16.2) both on iOS 18.1 and iOS 18.2 and got very different results:
In iOS 18.1 simulator, I see the settings of a lot of apps.
In iOS 18.2 simulator, not a single app setting.
That is a really serious issue in simulator for development (I filed a bug report FB16175635), but would be really critical on device as it would make it impossible to adjust setting of many apps.
Unless I missed something (meta setting ?) in iOS 18.2 ?
I have not upgraded to 18.2 notably for this reason. So I would appreciate if someone who has upgraded could make the test and report ?
select Settings on Home page
scroll to Apps category
tap here to access the list
Does the list show anything ?
Thanks for your help.
In this setup, label do not show properly because of the textColor.
Labels are defined in IB, in the following hierarchy:
ViewController
View
Label 1
scrollView
View
Button
Label 2
Buttons show properly, but labels, even though defined with default label color appear as if their alpha was 0.2. It is even worse in dark mode:
I have checked the settings for the label and did not find anything anormal:
I have tried to change label color to system.gray 2, to no avail. If I change to red, does not show in red in IB.
Problem appears for both Label 1 (at the top level in the view) and Label 2
I have an alertController that is presented as popover on iPad
let alertController = UIAlertController(title: alertTitle, message: alertMessage, preferredStyle: alertStyle)
if let ppc = alertController.popoverPresentationController {
// …
}
Is it possible to change the message font color (which is really very light on iPad) ?
It is OK on iPhone with the same alert (not popover): text is much more readable:
When picking a photo in the gallery, whatever the orientation of the original image, size is always as landscape
if let image = info[convertFromUIImagePickerControllerInfoKey(UIImagePickerController.InfoKey.editedImage)] as? UIImage {
print("picked original", image.size)
For a portrait photo:
picked original (1122.0, 932.0)
For a landscape:
picked original (1124.0, 844.0)
What am I missing ?
I have created a custom class:
class TarifsHeaderFooterView: UITableViewHeaderFooterView { …}
With its init:
override init(reuseIdentifier: String?) {
super.init(reuseIdentifier: reuseIdentifier)
configureContents()
}
I register the custom header view in viewDidLoad of the class using the tableView. Table delegate and data source are defined in storyboard.
tarifsTableView.register(TarifsHeaderFooterView.self, forHeaderFooterViewReuseIdentifier: headerTarifsIdentifier)
And call it:
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = tableView.dequeueReusableHeaderFooterView(withIdentifier: headerTarifsIdentifier) as! TarifsHeaderFooterView
That works on iPhone (simulators and devices).
But it crashes on any iPad simulator, as tableView.dequeueReusableHeaderFooterView(withIdentifier: headerTarifsIdentifier) is found nil.
What difference between iPhone and iPad do I miss that explains this crash ?
PS: sorry for the messy message. It looks like the new "feature" of the forum to put a Copy code button on the code parts, causes the code sections to be put at the very end of the post, not at the place they should be.
Is it only me (or a localisation issue in french) or is there a bug in the submission form (buttons titles):
But acceptance (dark blue button) works as intended.
Just testing an existing app with Xcode 26.
I notice that content of UIBarButtonItem (either text or image) disappears when tapped (and reappear on release).
Those are custom, bordered buttons.
Attribute inspector:
Buttons in Xcode:
When selected in Xcode, we see a rectangle inside the rounder rect of iOS 26
In simulator:
When tapped in simulator:
I have edited code from
backButton.setTitleTextAttributes([
.font : boldFont,
.foregroundColor : UIColor.systemBlue,
], for: .normal)
to
backButton.setTitleTextAttributes([
.font : boldFont,
.foregroundColor : UIColor.systemBlue,
], for: [.normal, .focused, .selected, .highlighted])
to no avail.
What am I missing ?
I sometimes use Xcode 14.2.
Recently, I have an issue with simulators:
on some SwiftUI project, the simulator list is empty.
I created a new project. I see the complete list of simulators, but when running for a simulator, it fails with following diag;
Same error with UIKit project.

System Information

I filed a bug report: FB18475006
When looking ay space used by system, I found that AssetsV2 (in System/Library) account for 270 GB.
In this folder, 3 account for 260 GB and are apparently related to Xcode simulators:
Content is a bit cryptic. Does it relate to some specific apps I compiled and ran on simulator ?
Or is it related to older versions of Xcode I keep on the Mac ?
How to know what each forlder relates to ? Is it safe to remove ?
According to this news, we don't need anymore (at least temporarily): https://www.macrumors.com/2025/12/23/texas-app-store-law-blocked/
A Texas federal judge today blocked an App Store age verification law that was set to go into effect on January 1, 2026, which means Apple may not have to support the changes after all.
Hope we shall get very rapidly more information from Apple.
I used to resize images (editing width and height when writing the post) in order to avoid ridiculously large images in reading published post.
Since a few weeks, that does not work anymore.
When I edit, I see the reduced size in Live Preview:
But once posted, images are much larger as seen below:
Looks like the image is now resized to fill full width.
I filed a bug report: Dec 27, 2025 at 1:43 PM – FB21446929
PS: that change ignores @eskimo wise advice "Quinn’s Top Ten DevForums Tips" n°10 (https://developer.apple.com/forums/thread/706527).
I have defined a class :
class Item: NSObject, NSSecureCoding {
var name : String = ""
var color : ColorTag = .black // defined as enum ColorTag: Int
var value : Int = 0
static var supportsSecureCoding: Bool {
return true
}
Its decoder includes the following print statement to start:
required init(coder decoder: NSCoder) {
print(#function, "item should not be nil", decoder.decodeObject(of: Item.self, forKey: someKey))
Another class uses it:
class AllItems: NSObject, NSSecureCoding {
var allItems : [Item]?
static var supportsSecureCoding: Bool {
return true
}
and decodes as follows
required init(coder decoder: NSCoder) {
super.init() // Not sure it is necessary
allItems = decoder.decodeObject(of: NSArray.self, forKey: mykey) as? [Item]
print(#function, allItems) // <<-- get nil
}
I note:
decoder returns nil at line 5
I have tried to change to
decoder.decodeObject(of: [NSArray.self, NSString.self, NSColor.self, NSNumber.self], forKey: mykey))
Still get nil
And, decoder of class Item is not called (no print in the log)
What am I missing ?
When compiling this OSX App in XCode 10 beta 2 (Swift 4.2), I get a warning that did not show in XCode 9.4 each time I create an NSConstraint programmaticallyInstance will be immediately deallocated because property 'myConstraint' is 'weak'fileprivate weak var myConstraint : NSLayoutConstraint!
myConstraint = NSLayoutConstraint(item: aButton, attribute: .top, relatedBy: .equal, toItem: aView, attribute: .bottom, multiplier: 1.0, constant: 30)However, there is no such warning for IBOutlet@IBOutlet fileprivate weak var anotherConstraint : NSLayoutConstraint!Is it a just a new warning for an error that existed before ? Or did something change in NSConstraint ?Should I treat IBOutlet and programmatically created differently with respect to weak ?
Learning Widgets, I try a simple pattern: get a textField in the app;
have the Widget updated when textField is changed.
App is UIKit.
Widget has No "included Configuration Intent".
It compiles and works. Widget is updated every 5 minutes as asked line 23 (final snippet).
But the message is never updated (line 48 of final snippet) with globalToPass (as expected from line 24): it always shows "Hello".
What I tried: Create a singleton to hold the data to pass:
class Util {
		
		class var shared : Util {
				struct Singleton {
						static let instance = Util()
				}
				return Singleton.instance;
		}
		
		var globalToPass = "Hello"
}
shared the file between the 2 targets App and WidgetExtension
In VC, update the singleton when textField is changed and ask for widget to reload timeline
		@IBAction func updateMessage(_ sender: UITextField) {
				
				Util.shared.globalToPass = valueToPassLabel.text ?? "--"
				WidgetCenter.shared.reloadTimelines(ofKind: "WidgetForTest")
				WidgetCenter.shared.reloadAllTimelines()
		}
Problem : Widget never updated its message field
Probably I need to have the message in @State var, but I could not get it work.
Here is the full widget code at this time:
import WidgetKit
import SwiftUI
struct LoadStatusProvider: TimelineProvider {
		
		func placeholder(in context: Context) -> SimpleEntry {
				
				SimpleEntry(date: Date(), loadEntry: 0, message: Util.shared.globalToPass)
		}
		func getSnapshot(in context: Context, completion: @escaping (SimpleEntry) -> ()) {
				
				let entry = SimpleEntry(date: Date(), loadEntry: 0, message: Util.shared.globalToPass)
				completion(entry)
		}
		func getTimeline(in context: Context, completion: @escaping (Timeline<Entry>) -> ()) {
				var entries: [SimpleEntry] = []
				// Generate a timeline consisting of five entries an hour apart, starting from the current date.
				let currentDate = Date()
				for minuteOffset in 0 ..< 2 {
						let entryDate = Calendar.current.date(byAdding: .minute, value: 5*minuteOffset, to: currentDate)!
						let entry = SimpleEntry(date: entryDate, loadEntry: minuteOffset, message: Util.shared.globalToPass)
						entries.append(entry)
				}
				let timeline = Timeline(entries: entries, policy: .atEnd)
				completion(timeline)
		}
}
struct SimpleEntry: TimelineEntry {
		let date: Date
		let loadEntry: Int
		let message: String
}
struct WidgetForTestNoIntentEntryView : View {
		var entry: LoadStatusProvider.Entry
		var body: some View {
				let formatter = DateFormatter()
				formatter.timeStyle = .medium
				let dateString = formatter.string(from: entry.date)
				return
						VStack {
								Text(String(entry.message))
								HStack {
										Text("Started")
										Text(entry.date, style: .time)
								}
								HStack {
										Text("Now")
										Text(dateString)
								}
								HStack {
										Text("Loaded")
										Text(String(entry.loadEntry))
								}
						}
		}
}
@main
struct WidgetForTestNoIntent: Widget {
		let kind: String = "WidgetForTestNoIntent"
		var body: some WidgetConfiguration {
				StaticConfiguration(kind: kind, provider: LoadStatusProvider()) { entry in
						WidgetForTestNoIntentEntryView(entry: entry)
				}
				.configurationDisplayName("My Widget")
				.description("This is an example widget.")
		}
}
struct WidgetForTestNoIntent_Previews: PreviewProvider {
		static var previews: some View {
				
				WidgetForTestNoIntentEntryView(entry: SimpleEntry(date: Date(), loadEntry: 0, message: "-"))
						.previewContext(WidgetPreviewContext(family: .systemSmall))
