I have added multiple status icons to my project, in the form of .icon files created with Icon Composer. The main app icon works, but the status icons are not working. I am attempting to load the images from the asset catalog using NSImage imageNamed:, and apply them to the NSApp dockTile using NSGlassEffectContainerView. I don't even know if that attempt is going to work, as I never get past the stage of NSImage loading the icons. Maybe someone on the forums knows what to do there? I'd be willing to use one of my coding support incidents to work through this if necessary, as my two incidents will expire as my subscription rolls over in August anyway. My project lives at https://github.com/losnoco/cog/, and the Tahoe attempt WIP lives in the wip.tahoe branch, with the latest commit as of this post being the attempt to adapt the Dock Icon generation. I'd love to know if I can adapt this easily. I'm also still trying to support existing non-Glass custom .png icons the user can add to their profile folder with buttons in the preferences, as well as supporting legacy status icons on pre-Tahoe installs. I also try to add a progress bar to the dock tile view when the app is processing something at length.

Hi! I am having issues with my internal testing app now showing up the same through different users devices?

I have a UITextView that contains paragraphs with text bullet lists (via NSTextList). I also implement NSTextContentStorageDelegate.textContentStorage(_:, textParagraphWith:) in order to apply some custom attributes to the text without affecting the underlying attributed text. My implementation returns a new NSParagraph that modifies the foreground color of the text. I based this on the example in the WWDC 21 session "Meet Text Kit 2". UITextView stops rendering the bullets when I implement the delegate function and return a custom paragraph. Why? func textContentStorage(_ textContentStorage: NSTextContentStorage, textParagraphWith range: NSRange) -> NSTextParagraph? { guard let originalText = textContentStorage.textStorage?.attributedSubstring(from: range) else { return nil } let updatedText = NSMutableAttributedString(attributedString: originalText) updatedText.addAttribute(.foregroundColor, value: UIColor.green, range: NSRange(location: 0, length: updatedText.length)) let paragraph = NSTextParagraph(attributedString: updatedText) // Verify that the text still contains NSTextList if let paragraphStyle = paragraph.attributedString.attribute(.paragraphStyle, at: 0, effectiveRange: nil) as? NSParagraphStyle { assert(!paragraphStyle.textLists.isEmpty) } else { assertionFailure("Paragraph has lost its text lists") } return paragraph }

Hello, I have encountered a question that I hope to receive an answer to. Currently, I am working on a music project for Mac Catalyst and need to enable music files such as FLAC to be opened by right clicking to view my Mac Catalyst app. But currently, I have encountered a problem where I can see my app option in the right-click open mode after debugging the newly created macOS project using the following configuration. But when I created an iOS project and converted it to a Mac Catalyst app, and then modified the info.plist with the same configuration, I couldn't see my app in the open mode after debugging. May I ask how to solve this problem? Do I need to configure any permissions or features in the Mac Catalyst project? I have been searching for a long time but have not found a solution regarding it. Please resolve it, thank you. Here is the configuration of my macOS project: CFBundleDocumentTypes CFBundleTypeExtensions flac CFBundleTypeIconSystemGenerated 1 CFBundleTypeName FLAC Audio File CFBundleTypeRole Viewer LSHandlerRank Default Note: Sandbox permissions have been enabled for both the macOS project and the iOS to Mac Catalyst project. The Mac Catalyst project also has additional permissions for com. apple. security. files. user taught. read write

We are experiencing an issue with session sharing on iOS and would appreciate your guidance. We operate and control our own OpenID Connect (OIDC) server. Our iOS application uses ASWebAuthenticationSession to authenticate users. We're unable to get the authentication session to be shared between the Safari app and the app's ASWebAuthenticationSession. This results in users having to re-authenticate despite being logged in via Safari. We've attempted various configurations related to cookie SameSite settings. These adjustments resolved the session sharing issue on Android using Chrome Custom Tabs. However, no changes we've tried have enabled session sharing to work as expected on iOS. According to documentation from Apple, Microsoft, Okta, and Auth0, session sharing between Safari and ASWebAuthenticationSession should work. Question: Are there any additional settings, configurations, or platform limitations we should be aware of that could impact session sharing on iOS? Where else can we look to resolve this issue?

iOS 18.4.1 When I change a Google type event to an iCloud type, a "Cannot Save Event" prompt box pops up. We have also received user feedback that recurring events also fail to save. After updating to iOS 18.4 when trying to save changes to an existing repeating event, the message "Cannot Save Event" will appear. EventKitUI

We've seen a spike in crashes on iOS 18.4 across both iPhone & iPad. We can't reproduce it, but it looks like it happens when the app goes into the background. Crash Log

I have a SwiftUI app which needs the Ivanti AppConnect SDK. The docs only show how to integrate it into a Swift/UIKit app. But I need it to work with SwiftUI. I probably could make a UIKit base app and then load my existing SwiftUI views and code through a SwiftUI component host or something. But I'd like to avoid that if possible. Here is where I'm stuck: The AppConnect framework loads through a custom UIApplication subclass in the main.swift file: import Foundation import AppConnect UIApplicationMain( CommandLine.argc, CommandLine.unsafeArgv, ACUIApplicationClassName, NSStringFromClass(AppDelegate.self) ) The startup works as expected, and the expected function is called in the AppDelegate class: func application( _ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {...} However, the SwiftUI view is not loaded and the scree stays blank. I implemented a SceneDelegate.swift class which doesn't seem to be called. Also, the following function in the AppDelegate doesn't get called either: func application( _ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {...} So how do I bootstrap SwiftUI with a custom UIApplication class? can that be done with the @main macro somehow? I'm still pretty new to Swift and iOS development. Any help is appreciated

In the Console, when presenting my view in a horizontally compact environment, I see: UINavigationController for collapsing UISplitViewController about to push view controller <UINavigationController: 0x107933c00> This message repeats infinitely, until the Xcode debugger eventually says: QUARANTINED DUE TO HIGH LOGGING VOLUME Of note is that this only occurs in the beta, does not occur when using the iOS 18.x SDK, and only occurs in a compact environment. EDIT: This occurs only when setting the secondary column of a doubleColumn UISplitViewController: splitVC.setViewController(secondary, for: .secondary) EDIT 2 and WORKAROUND: If this action is deferred until after viewDidAppear, it self-resolves: public override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) if let deferredSecondaryViewController { splitVC.showDetailViewController(deferredSecondaryViewController, sender: nil) } }

iOS 26 seems to have changed the way action extension icons appear in the share sheet. My icon is too small now compared to the Copy button in Safari (and Shortcuts’ icons are too small too, a bug?). How do you update it, and how do you ensure it looks fine in iOS 18 and earlier? My current icon is an AppIcon in the asset catalog, single size 1024x1024, with about 130px padding around it.

I want to add the option to choose an alternative icon inside the app. Is there a way to load an icon asset from within the app? I downloaded Apple’s alternative icon sample, which is supposed to show a list of icons to choose from, but even in the sample, it did not work. So the current solution is to add every alternative icon along with another image asset of the same image to display to the user. This sounds like a waste of bytes. Thank you in advance for any help.

I got 3 PKCanvasView, 2 below the Major one. Users draw lines on the top one, then sync the last stroke to the one underneath. If the stroke crosses two PKCanvasView, we replace the stroke with a bezier curve. If a stroke doesn't cross regions, we sync the stroke to the one below it(B) as if it is drawn directly on B. The problem is if the B is inside a UIScrollview with a zoom scale not 1, the stroke from major to B will shrink or grow. Does anybody have a solution for this please? What I did Also put the major canvas into a uiScrollview, and make sure the zoomScale is the same as the B. for scale >=1, it works as expected, for scale < 1, sometimes it works, sometimes it doesn't. for example, 0.5, 0.6, 0.8, 0.5 doesn't work, 0.6, 0.8 works, I don't know why. What it costs It cost me 16*4 hours for these days. I didn't find a solution. Hopefully, some one can solve it.

In order to make referencing keys for localized strings a little more reliable, our application references generated constants for localized string keys: This eliminates the potential for developers to misspell a key when referencing a localized strings. And because these constants are automatically generated by the exact same process that provides localized strings for the application, each and every constant is guaranteed to have a localized string associated with it. I’m currently attempting to implement something similar for the localized strings referenced by our new App Intents. Our initial release of App Intent functionality is simply using string literals to reference localized strings: However, I am running into several issues when trying to reference the string keys as a constant. The closest I managed to get was defining the constant as either a LocalizationValue or as a StaticString and referencing the constant while initializing the LocalizedStringResource. With this approach, I see no errors from Xcode until I try and compile. What’s more is that the wording of the error being thrown is quite peculiar: As you can see with the sample code above, I am clearly calling LocalizedStringResource’s initializer directly as Indicated by the error. Is what I’m trying to do even possible with App Intents? From my research, it does look like iOS app localization is moving more towards using string literals for localized strings. Like with String Catalog’s ability to automatically generate entries from strings referenced in UI without the need for a key. However, we’d prefer to use constants if possible for the reasons listed above.

The app puts button values into a text view area and controls the cursor. Upon an IOS touch screen, cut or paste, the IOS cursor loses sync with the app cursor causing an address out of bounds and fails. The IOS cut or paste changes the cursor position and the text.endIndex address by shrinking or expanding the text field. IOS doesn't know about the app cursorPosition. If IOS could update the app cursor position and the text.endIndex position would solve the problem. Or if the app knew about the IOS change could update the app cursor position and the text.endIndex. The current work around is the user sets the cursor to the text.startIndex using an app navigating button before the touch screen. The app does not fail. The user then navigates the cursor using arrow buttons to another position. To see this happen download the free SummaGramIPAD Trial.(13") TSIs have been requested with engineer suggestions for well over one year. I hope someone could figure this out. I just finished SummaGram iPhone and would like to host it. Thanks for your help. Charlie

Hello everyone, I’d appreciate if anyone can tell me if there’s a way to actually control visual layout of subviews in a predicate editor row template. I have a predicate editor with custom row template subclasses, all created in code (not in IB) and it all works fine, but the problem are template (sub)views, which are not NSPopUpButton(s). As I select different items of popup buttons, effectively changing editor’s predicate property, those buttons seem to get resized according to some strange own logic, but the general the problem is that size (width) of controls, such are text fields and date pickers, gets unpredictable and they usually shrink, even though there is still a plenty of room in the template row width. Trying to resize any control in a row template by force (setFrame: or setFrameSize:) has no effect. I can show some screenshots and videos of the behaviour, as well as code samples, if necessary, but I’d like to ask first, maybe someone already knows what I’m talking about and provide some insights and solutions. Thanks in advance.

I have a widget that runs well on iOS 18. It is configurable and implements AppIntentTimelineProvider on the Provider. On iOS 17 it will call the placeholder method 7 times and not call the timeline method. The configuration intent implements WidgetConfigurationIntent. I've looked through the console logs and saw "ApplicationExtension record not found" but I'm not sure where to go from there. Why would the same widget work fine on iOS 18 and not 17? If I implement TimelineProvider and use a StaticConfiguration it works on iOS 17. Any help / guidance would be appreciated.

Hi! I'm seeing some weird animation issues building the Food Truck sample application.^1 I'm running from macOS 15.4 and Xcode 16.3. I'm building the Food Truck application for macOS. I'm not focusing on iOS for now. The FoodTruckModel adds new Order values with an animation: // FoodTruckModel.swift withAnimation(.spring(response: 0.4, dampingFraction: 1)) { self.orders.append(orderGenerator.generateOrder(number: orders.count + 1, date: .now, generator: &generator)) } This then animates the OrdersTable when new Order values are added. Here is a small change to OrdersTable: // OrdersTable.swift - @State private var sortOrder = [KeyPathComparator(\Order.status, order: .reverse)] + @State private var sortOrder = [KeyPathComparator(\Order.creationDate, order: .reverse)] Running the app now inserts new Order values at the top. The problem is I seem to be seeing some weird animation issues here. It seems that as soon as the new Order comes in there is some kind of weird glitch where it appears as if part the animation is coming from the side instead of down from the top: What's then more weird is that if I seem to affect the state of the Table in any way then the next Order comes in with perfect animation. Scrolling the Table fixes the animation. Changing the creationData sort order from reverse to forward and back to reverse fixes the animation. Any ideas? Is there something about how the Food Truck product is built that would cause this to happen? Is this an underlying issue in the SwiftUI infra?

In UIKit, UIButton provides a configuration property which allows us to create and customize a UIButton.Configuration instance independently (on a background thread or elsewhere) and later assign it to a UIButton instance. This separation of configuration and assignment is very useful for clean architecture and performance optimization. Questions: Is this configuration-style pattern (creating a configuration object separately and assigning it later) available or planned for other UIKit components such as UILabel, UITextField, UISlider, etc.? Similarly, in AppKit on macOS, are there any components (e.g. NSButton, NSTextField) that support a comparable configuration object mechanism that can be used the same way — constructed separately and assigned to the view later? This would help in building consistent configuration-driven UI frameworks across Apple platforms. Any insight or official guidance would be appreciated.

Hello everyone, I’m currently developing an iOS app and would like to leverage the AccessorySetupKit framework introduced in iOS 18 to implement pairing functionality with our company's custom hardware product. The specific requirements are as follows: Our hardware supports both Bluetooth and Wi-Fi connections, and both are enabled. When the hardware device is in proximity to an iPhone, I want the device to be automatically recognized, and a pairing screen similar to the one in AccessorySetupKit should appear. Users should be able to perform the pairing process without needing to open our app, even if the app is not in the foreground. The system-level pairing screen should show the hardware information and allow the user to proceed with the pairing. My questions are: Does AccessorySetupKit allow the pairing screen to trigger when the app is running in the background, or must the app be in the foreground? How should I configure AccessorySetupKit to automatically recognize and display my company’s hardware device information? Are there any specific configurations or code implementations needed? Do I need to implement any specific Bluetooth/Wi-Fi advertising broadcasts to ensure the device is correctly detected by the iOS system when in proximity? Are there any additional permissions or configurations required, especially for handling background tasks? Thank you very much for your help, and I look forward to your advice and insights!
