swiftui

I was looking through: https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/ScriptableCocoaApplications/SApps_handle_AEs/SAppsHandleAEs.html And wondered how these are handled for SwiftUI apps. What would I add or override?

Code example: // // ListSafeAreaBarKeyboardTextField.swift // Exploration import SwiftUI import Foundation struct ListSafeAreaBarKeyboardTextField: View { @State private var typedText: String = @FocusState private var focusingTextField: Bool private let items = Array(1...16) var body: some View { ScrollViewReader { proxy in List(items, id: .self) { number in Text(Item (number)) .id(number) } .onAppear { if let lastItem = items.last { proxy.scrollTo(lastItem, anchor: .bottom) } } .onChange(of: focusingTextField) { oldValue, newValue in // This simply won't work // ~ 12th - 16th item will still get covered by keyboard if newValue == true { // Delay to allow keyboard animation to complete DispatchQueue.main.asyncAfter(deadline: .now() + 0.3) { if let lastItem = items.last { withAnimation { proxy.scrollTo(lastItem, anchor: .top) } } } } } } .scrollDismissesKeyboard(.interactively) .safeAreaBar(edge: .bottom) { TextField(Type here, text: $typedText, axis: .vertical) .focused($focusingTextField) // Design

SwiftUI's colorScheme modifier is said to be deprecated in favour of preferredColorScheme but the two work differently. See the below sample app, colorScheme changes the underlying view colour while preferredColorScheme doesn't. Is that a bug of preferredColorScheme? import SwiftUI struct ContentView: View { let color = Color(light: .red, dark: .green) var body: some View { VStack { HStack { color.colorScheme(.light) color.colorScheme(.dark) } HStack { color.preferredColorScheme(.light) color.preferredColorScheme(.dark) } } } } #Preview { ContentView() } @main struct TheApp: App { var body: some Scene { WindowGroup { ContentView() } } } extension UIColor { convenience init(light: UIColor, dark: UIColor) { self.init { v in switch v.userInterfaceStyle { case .light: light case .dark: dark case .unspecified: fatalError() @unknown default: fatalError() } } } } extension Color { init(light: Color, dark: Color) { self.init(UIColor(light: UIColor(light), dark: UIColor(dark))) } }

using Version 26.2 (17C52) I often get Trace file had no SwiftUI data why so?

I am trying to port my sandboxed macOS app completely over to iOS using a Catalyst target. In my macOS app, I use 'SwiftySandboxFileAccess' package to add a symlink to '~/Library/PDF Services' so that the 'share to my app' menuItem shows up in the macOS Print Panel (in the PDF menu). It is critical for the function of my app to have this work on macOS. In the Catalyst target, I am having problems gaining access to '~/Library'. I have tried having the user select the folder, but the picker always returns 'canceled'. I have a test app that illustrates this. The test app tries to coax the user into selecting the library folder and then it is supposed to bookmark the location, but I am unable to get this far. As an aside, macOS should probably automatically add an entry to the Print Panel when the app includes PDF as a document type in XCode; it would save a lot of hassle and avoid having to go outside of the sandbox. However, I cannot wait for that. Hopefully someone can help. Download Test App from iCloud (If y

I have found that following code runs without issue from Xcode, either in Debug or Release mode, yet crashes when running from the binary produced by archiving - i.e. what will be sent to the app store. import SwiftUI import AVKit @main struct tcApp: App { var body: some Scene { WindowGroup { VideoPlayer(player: nil) } } } This is the most stripped down code that shows the issue. One can try and point the VideoPlayer at a file and the same issue will occur. I've attached the crash log: Crash log Please note that this was seen with Xcode 26.2 and MacOS 26.2.

I am creating a macOs SwiftUI document based app, and I am struggling with the Window sizes and placements. Right now by default, a normal window has the minimize and full screen options which makes the whole window into full screen mode. However, I don't want to do this for my app. I want to only allow to fill the available width and height, i.e. exclude the status bar and doc when the user press the fill window mode, and also restrict to resize the window beyond a certain point ( which ideally to me is 1200 x 700 because I am developing on macbook air 13.3-inch in which it looks ideal, but resizing it below that makes the entire content inside messed up ). I want something like this below instead of the default full screen green When the user presses the button, it should position centered with perfect aspect ratio from my content ( or the one I want like 1200 x 700 ) and can be able to click again to fill the available width and height excluding the status bar and docs. Here is my entire @main cod
