I have a view in storyboard, with a tableView and a coloured UIView. The UIView is declared after tableView, so it appears on top of tableView. However, it appears semi transparent over the tableView. In addition, I cannot set its alpha channel to values other than 1 or 0 (e.g., 0.9) But if I create the view programmatically, the view if fully opaque as expected. What am I missing ?

This is an often asked question, but I just have a partial answer so far. There are some views (not all) that I need to present in Portrait only when running on iPhone. If I come from a TabBar, I just add the following code in the TabBar controller override open var supportedInterfaceOrientations : UIInterfaceOrientationMask { if UIDevice.current.userInterfaceIdiom == .phone { return [.portrait, .portraitUpsideDown] } } But I need to do the same when I get to the destination VC by a segue fired from a plain UIViewController or a Cell in a TableView. If I put the code in the destination controller, it has no effect. If I put in the originating VC, it works when segue is triggered from code (case 2 below). But I cannot make it work when segue is triggered in storyboard from the accessory action in the cell of the TableView. Where should I declare the supportedInterfaceOrientations ? Should I do it in the navigation root ? If so, how ? I tried in an extension UINavigationController, to no avail. or should I trigger the segue from accessory, not directly in storyboard but through an IBAction in code ? If that may help, an overview of storyboard setup: Also tried solution described here to no avail either: https://www.appsdeveloperblog.com/disable-rotation-of-uiviewcontroller-embedded-into-uinavigationcontroller/

I had this code working properly in Xcode 17.0.1, with macOS target as 12.4 struct SyntheseView: View { @AppStorage("isDarkMode") var isDarkMode = false // more declarations ……… var body: some View { VStack { ZStack { // code ………………… } .frame(width: 500, height: 300) .background(isDarkMode ? Color(red: 0, green: 0, blue: 120/255) : Color(red: 1, green: 1, blue: 186/255)) } // VStack In Xcode 15.3, I get the error The compiler is unable to type-check this expression in reasonable time; try breaking up the expression into distinct sub-expressions If I comment out the background modifier, no issue. I converted all parameters in Color to Double without success If I replace by a fixed color as .background(.blue) No error. Even the simple .background(Color(red: 0.0, green: 0.0, blue: 0.5)) causes the error. But: .background(isDarkMode ? .blue : .red) does work. I tried to define the Colors as static color extensions to no avail. Another bizarre point is that a similar pattern works OK for another View. Did something change in Xcode 17.3 ?

I prepare an app to migrate from ObservableObject to Observable, from EnvironmentObject to Environment(MyClass.self) and so so forth. That works OK, very simple. But, that forces to run on macOS 14 or more recent. So I would like to have it conditionally, such as: if macOS 14 available @Environment(ActiveConfiguration.self) var activeConfiguration: ActiveConfiguration otherwise @EnvironmentObject var activeConfiguration: ActiveConfiguration The same for the class declaration: if macOS 14 available @Observable class ActiveConfiguration { var config = Configuration() } otherwise class ActiveConfiguration : ObservableObject { @Published var config = Configuration() } Is there a way to achieve this (I understand it is not possible through extensions of Macros, as we can do for modifiers) ? Could I define 2 classes for ActiveConfiguration, but then what about @Environment ?

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)?

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 ?

This app may run on MacOS or iOS. I want to use windowResizability modifier (specially In MacOS) which is only available on masOS 13+ and iOS 17+, but still need to run on macOS 12 or iOS 15… So I need something like #if os(macOS) if #available(macOS 13 *) { use windowResizability #else do not use windowResizability #endif #else // iOS if #available(iOS 17 *) { use windowResizability #else do not use windowResizability #endif Here is the code where to apply (in @main) struct TheApp: App { var body: some Scene { WindowGroup { ContentView() // 1.11.2023 .frame( minWidth: 1200, maxWidth: .infinity, minHeight: 600, maxHeight: .infinity) } .windowResizability(.contentSize) // BTW: is that really necessary ? } } How can I achieve this ? Do I need to write a WindowGroup extension for the modifier ? If so, how ? BTW: is windowResizability really necessary ? App seems to work the same without it.

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).

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 ?
