Is it possible under macOS to drag a file from an app into the Finder?
For example, I want to drag a CSV file from the app to the Finder, but the following code does not work.
static var transferRepresentation: some TransferRepresentation {
FileRepresentation(exportedContentType: .commaSeparatedText) {_ in
SentTransferredFile(Bundle.main.url(forResource: "Demo", withExtension: "csv")!)
}
}
And I changed the exportedContentType to ".fileUrl", ".url" and ".data" but the code still does not work.

It works on Monterey, but not work on Ventura.
struct ContentView: View {
@FocusState private var focus: FocusableElement?
@FocusedValue(\.focusedElement) var focusElement
var body: some View {
VStack(spacing: 30) {
HStack {
GroupBox {
Circle()
.focusable()
.focused($focus, equals: .circle)
.focusedValue(\.focusedElement, .circle)
.frame(width: 100, height: 100)
.padding()
Text(focus == .circle ? "Selected" : "Not selected")
}
.onTapGesture {
focus = .circle
}
GroupBox {

}
Text("Focused Element: \(focusElement?.rawValue ?? "None")")
}
.padding()

.commandsRemoved() does not work for the Window and WindowGroup scenes if it’s the primary group (first one).
Then I tried to add new menu using the code
.commands {
CommandGroup(replacing: .newItem) {
Button("New Document") {
newDocument { TestDocument() }
}
.keyboardShortcut("n")
}
But app crashed with error " Expected subclass override"
The test app is a document-based app, with a welcome window using the new Window scene.

I created a new iOS project targeting iOS 15 using Xcode 13.0 beta (13A5154h) on Big Sur to test some new SwiftUI features.
Xcode shows me the error like "*** is only available in iOS 15.0 or newer" for all new API for iOS 15.
The project target is iOS 15
I tried to create another project again, same problem.
Would you please help to fix it?
Thanks a lot!

By default, the events (mouse/cursor/scroll...) are bypassed to the controls under the NSView, for example, there are one NSView (named A) and one NSTextField (named B). A and B are at same place, and A is above B.All mouse events passed to B (TextField)Cursor has been changed as "I", not the default cursor as expectedScroll mouse will scroll B (the textfield if multiple lines)I'd like that if mouse on A (the NSView), all the events are not passed to B. So I subclass NSView for A as the code following:// ------------------------------------------------class ResponsibleView: NSView { override func acceptsFirstMouse(theEvent: NSEvent?) -> Bool { return true } override var acceptsFirstResponder : Bool { return true } override func mouseUp(theEvent: NSEvent) { } override func resetCursorRects() { superview?.resetCursorRects() self.addCursorRect(self.bounds, cursor: NSCursor.arrowCursor()) } override func scrollWheel(theEvent: NSEvent) { }}// ------------------------------------------------Now there is a problem on cursor - the cursor is not stable, sometimes the cursor appears correctly, but sometimes incorrect. Would you please help to check following my questions?- Is there simple solution to avoid events bypassing NSView?- Why the cursor is too strange, how to make it be stable?- Why the cocoa for OSX makes things too complicated and not be intuitive? ( I am new for OSX development), is there any modern UI solution for OSX like XAML ...Thanks,

I tried to create a menu item with full width of the screen, as following the code:
VStack {
Menu {
Button("Option 1", action: actionOne)
Button("Option 2", action: actionTwo)
} label: {
Label("Options", systemImage: "paperplane")
.padding()
}
.frame(maxWidth: .infinity)
} And tried to change the label using HStack
VStack {
Menu {
Button("Option 1", action: actionOne)
Button("Option 2", action: actionTwo)
} label: {
HStack {
Text("Options")
Spacer()
}
.padding()
}
.frame(maxWidth: .infinity)
} And tried to customize using MenuStyle.
But the menu label renders NOT in the full width using all preceding the codes.
Would you please help to check and share me the solution?
Thanks,
Philip

The keyboard shortcut does not work on the iPadOS 14 simulator using following the code.
@main
struct DemoApp: App {
var body: some Scene {
WindowGroup {
Text("Demo Keyboard Shotcuts")
}
.commands {
CommandGroup(before: .sidebar) {
Button("Test Keyboard", action: { print("keyboard shortcut - command + k") })
.keyboardShortcut("[")
}
}
}
}
Would you please help us to know what's the problem? From the WWDC session "What's new in SwiftUI", the keyboard shortcut should work on iPad.
Thank you.

We need to show a welcome window before creating a new document (or by the choose of the user to create a new document). Would you mind sharing us an example for how to show a welcome window (not a document window) when the app start?

We have waiting one year for the Collection View with layout customizable capability since last WWDC, as our app needs to customize the layout. @Apple do you have plan to implement it or if there is one already? The Lazy..Grid is not what we want.
Thank you.
We believe it's time to start developing apps using SwiftUI by watched the WWDC20 "Keynote" and "Platforms State of the Union".
We are planning to develop an app for the iOS and macOS, and we'd like to macOS app to be fine tuned to use the macOS native capabilities. I am wondering what's the recommend way that @Apple prefer to do for the new app using SwiftUI for developing the macOS app, catalyst or native? (sharing code is not the key, we can copy :) )
Thank you.

Hello,My app supports to open file via UIDocumentPickerViewController, and the app needs to detect if the opened file is writable.We are using the "isWritableFileAtPath" method to detect if the file is writable, but iCloud Drive behaviors strangly:----Case one:Sharing a file directly with readonly permission from iCloud account A to iCloud account B, "isWritableFileAtPath" return "false" on the device of the B user - that's what we expected.----Case two:Sharing a FOLD with readonly permission from iCloud account A to iCloud account B, "isWritableFileAtPath" for a file in the shared folder returns "true" on the device of the B user - that's NOT what we expected.=============Would you please help us on it?- Is it a bug of the iCloud Drive?- Or if there is another way to detect if the app has permission to write the file opened using UIDocumentPickerViewController ?Thanks,Philip
