If item changes, the system dismisses the currently displayed action sheet and replaces it with a new one using the same process.
content: A closure returning the ActionSheet you create.

Use this method when you need to populate the fields of an action sheet with content from a data source. The example below shows a custom data source, FileDetails, that provides data to populate the action sheet:

struct FileDetails: Identifiable {
    var id: String { name }
    let name: String
    let fileType: UTType
}
struct ConfirmFileImport: View {
    @State var sheetDetail: FileDetails?
    var body: some View {
        Button("Show Action Sheet") {
            sheetDetail = FileDetails(name: "MyImageFile.png",
                                      fileType: .png)
        }
        .actionSheet(item: $sheetDetail) { detail in
            ActionSheet(
                title: Text("File Import"),
                message: Text("""
                         Import \(detail.name)?
                         File Type: \(detail.fileType.description)
                         """),
                buttons: [
                    .destructive(Text("Import"),
                                 action: importFile),
                    .cancel()
                ])
        }
    }


    func importFile() {
        // Handle import action.
    }
}
