A new message 'Answered by forumsContributor in' with a link to nowhere
I see this message for the first time: It is inserted in the OP (https://developer.apple.com/forums/thread/757852) but the link leads to nowhere (just the general page of the forum). In … what ?!? So I wonder what is the meaning of the message, its intent and use ? Or is it just a forum bug ? PS: surprisingly, this post appears in Forums general page (https://developer.apple.com/forums/latest), but not in forums feedback (https://developer.apple.com/forums/tags/forums-feedback) PS2: it appears, but after all the pinned messages which are older. Really confusing… I posted a bug report on this: Jun 23, 2024 at 9:29 PM – FB14024970

Irrelevant automatically generated answers on the forum
I've recently seen answers to posts that are apparently automatically generated but signed as App Store Connect Engineer. In several cases the answer is misinterpreting the OP. Here is an example: https://developer.apple.com/forums/thread/758391 The OP was really a developer question. Not related to a consumer feature. Is it really an automatic answer (which would be a bad trend for the forums IMHO)?

PullDown menu shows in reverse order when in landscape
I create a UIKit PullDown menu (in a positionMenu button), with the following code: func setupPullDownMenu() { let menu1 = UIAction(title: "Menu1") { [self] _ in // some code } let menu2 = UIAction(title: "Menu2") { [self] _ in // some code } let menu3 = UIAction(title: "Menu3") { [self] _ in // some code } let menu = UIMenu(title: "Positions", children: [menu1, menu2, menu3]) positionMenu.menu = menu positionMenu.showsMenuAsPrimaryAction = true }   In Portrait, options are listed as Menu1, Menu2, Menu3 But in Landscape it is the reverse: Menu3, Menu2, Menu1 I use Xcode 16.1ß and iOS 17.0 simulator Is it the expected behaviour ?

preferredColorScheme not working with Xcode 16
In this app, I set the preferredColorScheme in main @main struct TheApp: App { @AppStorage("isDarkMode") private var isDarkMode = false var body: some Scene { WindowGroup { ContentView() .preferredColorScheme(isDarkMode ? .dark : .light) } } } isDarkMode is changed dynamically in code. When code is compiled with Xcode 15.3, the background of ContentView changes from light to dark or vice versa. When compiled with Xcode 16, no more change. However, direct changes to objects do work, such as: TextField("N", value: $t, format: .number) .frame(width: 40) .background(isDarkMode ? .gray : .white) What has changed in Xcode 16 ? Is it documented somewhere ? I saw this SO thread which describe similar problem. https://www.reddit.com/r/swift/comments/upkprg/preferredcolorscheme_toggle_not_working/

Changing background colour of Button changes the container background
To change the background of a TextField, I simply apply: TextField("0.0", value: $p, format: .number) .textFieldStyle(PlainTextFieldStyle()) .background(.red) That does only work with plain style, but it works. Trying something similar on a button changes the container view background. The only solution I've found is to overlap with a Rectangle. How is it ? A SwiftUI bug ? A current limit of Swift ? A rationale for it ? There a better solution I've not found ?

Developing a driver to read HFS disks on MacOS Sonoma and newer
Capability to read and write ofd HFS disks on Mac has been removed since a long time. Capability to simply read was also removed since Catalina I think. That is surprising and sometimes frustrating. I still use a 90's MacBook for a few tasks and need from time to time to transfer files to newer Mac or read some old files stored on 3.5" disks. Solution I use is to read the disk on an old Mac with MacOS 10.6 (I'm lucky enough to have kept one) and transfer to USB stick or airdrop… As there is no USB port on the Macbook of course (and I have no more a working 56k modem to transfer by mail), only option if not 3,5" disk is using PCMCIA port on the MacBook for writing to an SD Card to be read in Mac Sonoma. But reading directly 3.5" disk would be great. Hence my questions for the forum: how hard would it be to write such a driver for READING only HFS on Mac Sonoma? There are some software like FuseHFS. Did anyone experience it ? Did anyone have a look at the source code (said to be open source). does anyone know why Apple removed such capability (I thought it was a tiny piece of code compared to the GB of present MacOS)? Thanks for any insights on the matter.

Typographic question for space character
In this UIKit app, I have to display numbers (from 1 to 100), in a label., on several lines, with 8 numbers on each line. Order is computed by the app for a specific purpose. The numbers are separated by space. Label font is Helvetica Neue 15.0. I want to get them aligned vertically. So, I have a padding so that they are all the same length of 4. Problem: the space have smaller width (half in fact) than digits, so alignment is disrupted: Of course, I can use fixed width fonts (like Menlo), but I've not found one that fits (the zero is barred, which is not looking great in the app). I have tried using class func monospacedDigitSystemFont( ofSize fontSize: CGFloat, weight: UIFont.Weight ) -> UIFont and apply to label.text. To no avail as it modifies only digits, not space char. I have found a workaround, padding with 2 spaces instead of one, but is there another solution ? So I am looking for a space character that would have the same width as a digit. There existe thin space (https://en.wikipedia.org/wiki/Whitespace_character) but not larger space. Does it exist ?

Immediate crash of Apple Watch simulator when typing a key
I get a crash in Apple Watch simulator (Series 9 45mm 18.0) as soon as the app launch if I type anything on external keyboard (just hitting command key for instance to capture a screenshot). Same crash on series 7 (45mm, OS 18.1) But app works normally when I use mouse to interact with the app on simulator. App does not crash on real device (Watch 4 OS 10.4.1). Nor does it crash on Series 6 simulator (44 mm OS 17.4). Here are the log I could collect (apparently, they contain sensitive language !!! so I attach as a file.: Attached logs

labels appear as dimmed in UIView
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

Set UILabel color in alertController
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:

Picked photo in the gallery does not recognise image orientation
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 ?

URL passed as attachment to notification is deleted when notification is added
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 ?

Change app language on Apple Watch simulator
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 ?

tableView.dequeueReusableHeaderFooterView(withIdentifier: ) crashes on iPad only
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.
