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 create a notification with an image attachment: let center = UNUserNotificationCenter.current() center.delegate = self let content = UNMutableNotificationContent() // some more stuff… let paths = NSSearchPathForDirectoriesInDomains( FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.userDomainMask, true) let documentsDirectory = paths[0] as NSString let fileExtPNG = "#" + "\(imageName)" + " photo.png" let fileNamePNG = documentsDirectory.appendingPathComponent(fileExtPNG) as String url = URL(fileURLWithPath: fileNamePNG) let attachment = try UNNotificationAttachment(identifier: "Image", url: url, options: nil) content.attachments = [attachment] I then add the request: let request = UNNotificationRequest(identifier:requestIdentifier, content: content, trigger: nil) center.removePendingNotificationRequests(withIdentifiers: [requestIdentifier]) center.add(request) {(error) in } Problem: when I later test (once notification has been registered), the file do not exist anymore at the url. I've commented out the add request to confirm. I have a work around, by creating a temporary copy of the file at the URL and pass it in the attachment. Then, everything works fine and the copy is deleted. But that's a bit bizarre. What am I missing here ?

I feel a bit dumb now. I once succeeded to change the language of an app on Watch simulator. So it is possible. And I'm not able to repeat (fool of me I did not took note of how I did it). I just remember it was simply through some language settings selection, may be rebooting the Mac, but not by changing anything in code. Does someone know how to do ?

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.

I tried to post a reply to a thread. It seems to be posted, but does not appear in the thread once sent…

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'm struggling to convert Swift 5 to Swift 6. As advised in doc, I first turned strict concurrency ON. I got no error. Then, selected swift6… and problems pop up. I have a UIViewController with IBOutlets: eg a TextField. computed var eg duree func using UNNotification: func userNotificationCenter I get the following error in the declaration line of the func userNotificationCenter: Main actor-isolated instance method 'userNotificationCenter(_:didReceive:withCompletionHandler:)' cannot be used to satisfy nonisolated requirement from protocol 'UNUserNotificationCenterDelegate' So, I declared the func as non isolated. This func calls another func func2, which I had also to declare non isolated. Then I get error on the computed var used in func2 Main actor-isolated property 'duree' can not be referenced from a nonisolated context So I declared duree as nonsilated(unsafe). Now comes the tricky part. The computed var references the IBOutlet dureeField if dureeField.text == "X" leading to the error Main actor-isolated property 'dureeField' can not be referenced from a nonisolated context So I finally declared the class as mainActor and the textField as nonisolated @IBOutlet nonisolated(unsafe) weak var dureeField : UITextField! That silences the error (but declaring unsafe means I get no extra robustness with swift6) just to create a new one when calling dureeField.text: Main actor-isolated property 'text' can not be referenced from a nonisolated context Question: how to address properties inside IBOutlets ? I do not see how to declare them non isolated and having to do it on each property of each IBOutlet would be impracticable. The following did work, but will make code very verbose: if MainActor.assumeIsolated({dureeField.text == "X"}) { So I must be missing something.

Since recently, when I try to close a thread I created on an answer of mine, I get the following error: Trying later, next day, does not solve it. In the list of all threads, the post is not marked as answered. But if I look via Chrome or plain Safari, I see the answer itself is marked as correct: Which is not the case when opening in Safari Technology Preview (Release 233) where the same answer is still to be accepted:

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 a large code that I try to update to change deprecated APIs. In the former version, I used forWritingWith and forReadingWith let data = NSMutableData() let archiver = NSKeyedArchiver(forWritingWith: data) archiver.encode(myObject, forKey: theKey) if let data = NSMutableData(contentsOf: anURL) { let unarchiver = NSKeyedUnarchiver(forReadingWith: data as Data) let myObject = unarchiver.decodeObject(forKey: theKey) as! TheObjectType // <<-- returns the object That I changed to let data = NSMutableData() let archiver = NSKeyedArchiver(requiringSecureCoding: true) archiver.encode(myObject, forKey: theKey) if let data = NSMutableData(contentsOf: anURL) { do { let unarchiver = try NSKeyedUnarchiver(forReadingFrom: data as Data) let myObject = unarchiver.decodeObject(forKey: theKey) as? TheObjectType // <<-- This returns nil This builds correctly. But on execution, unarchiver.decodeObject now returns nil. I have searched extensively to find the cause to no avail. I may probably change the design to avoid NSKeyedArchiver, but that would be a huge refactoring. I probably miss something obvious. Could someone hint at the possible cause ?

I need to encode and decode Array<Array> SomeStruct is multiplexed in an Int The former API did work: if let format = decoder.decodeObject(forKey: someKey) as? Array<Array<SomeStruct>> { } But using the new API if let format = decoder.decodeObject(of: Array<Array<Int>>.self, forKey: someKey) { generates an error: Cannot convert value of type 'Array<Array<Int>>.Type' to expected argument type '[AnyClass]' (aka 'Array<any AnyObject.Type>') encoding is done as follows: var format = Array(repeating: Array(repeating: 0, count: 4), count: 4) // initialize the var coder.encode(format, forKey: someKey) What is the correct syntax ?

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 ?
