I have a SwiftUI document based app where multiple documents can be open at the same time.
I now want to have menu items in the main menu that send commands to the active window.
Additionally, I want menu items to be disabled if no matching object is selected in the active window.
As an example Finder can be used, where in the "Edit" menu the entries are different depending on the selected files.
I tried using a class as shown below to communicate between the views and the Commands structure, which basically works.
Unfortunately, this causes a command to arrive at all open documents.
And if I have an entry selected in one window but not in another, the AppState object only reflects the last selected state. If I change the window, the app does not notice this for the time being.
class AppState: ObservableObject
{
static let shared = AppState()
@Published var dirEntryCommand = PassthroughSubject<DirCommand,Never>()
@Published var selectedDirEntry: DirectoryEntry.ID?
}
The Commands struct looks like this:
enum DirCommand: Int, Identifiable, CaseIterable
{
case rename
case moveUp
case moveDown
var id: RawValue { rawValue }
}
struct DirEntryCommands: Commands
{
@ObservedObject var appState = AppState.shared
var body: some Commands {
CommandMenu("Directory Entry") {
Section {
Button("Move up") {
appState.dirEntryCommand.send(.moveUp)
}
.keyboardShortcut("u")
Button("Move down") {
appState.dirEntryCommand.send(.moveDown)
}
.keyboardShortcut("d")
}
.disabled(appState.selectedDirEntry == nil)
Section {
Button("Rename…") {
appState.dirEntryCommand.send(.rename)
}
.keyboardShortcut("r")
}
.disabled(appState.selectedDirEntry == nil)
}
}
}
It is possible that I am taking the wrong approach and that there is another solution to this problem.
In a pure AppKit application I would implement the relevant commands in the ViewController and use the "magic" of the ResponderChain.

In a project that uses the Combine Framework, the following error suddenly occurs:
Failed to build module 'Combine'; this SDK is not supported by the compiler (the SDK is built with 'Apple Swift version 5.5 (swiftlang-1300.0.24.14 clang-1300.0.25.10)', while this compiler is 'Apple Swift version 5.5 (swiftlang-1300.0.24.13 clang-1300.0.25.10)'). Please select a toolchain which matches the SDK.
I must confess that I do not understand what the problem is. Is this an Xcode problem or can I solve it myself?
Strangely enough, I was able to compile and run the project several times before without any problem.
Furthermore, the error is not displayed in my code, but in the package https://github.com/MaxDesiatov/XMLCoder which I included using cocoapods.

I've a small extension for the Date type with some simple helper methods like
func dateByAdding(components: DateComponents) -> Date?
{
return Calendar.current.date(byAdding: components, to: self)
}
Now there's one class where Xcode 13.0 beta 2 keeps telling me Type 'Date' has no member 'dateByAdding' while in another class the extension works as expected.
All files are 100% swift and all relevant files have a Target Membership of the same target.
I've tried the usual things like removing the Derived Data folder, but without success. Any ideas what could cause this?

Hi there,
is there any way to select which interface the network link conditioner affects? I found an old article (https://discussions.apple.com/thread/3287471), which suggest using ipfw commands, but that does not seem to work in MacOS BigSur (I'm on 11.2.2 (20D80)).

Hi all,
I've a UITableViewController wich display a search bar by assigning a search controller to it's navigationItem.searchController
property.
It also displays a section index with UITableView.indexSearchas first element.
Is there any way to force the navigation bar to show the search bar, when the corresponding section index is tapped.
In tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index; I'm only able to return a section index.
navigationItem.hidesSearchBarWhenScrollingis set to true, so even returning 0 only displays the first section. I need to scroll down manually, for the search bar to become visible.

Hello,I'm trying to get a little smarter about core Bluetooth. :-)I have an app on device 1 which advertises a service using peripheralManager.startAdvertising([CBAdvertisementDataServiceUUIDsKey:[serviceCBUUID],
CBAdvertisementDataLocalNameKey: localName])On a second device I use centralManager.scanForPeripherals(withServices: [serviceCBUUID],
options: [CBCentralManagerScanOptionAllowDuplicatesKey:true])to be notified as soon as a device with the desired service is available.So far everything works without any problems.However, if I carry out the following steps on device 1:Put the app in background (the corresponding background mode is activated)Bring the app back to foreground.End the advertising of the service with peripheralManager.removeAllServices()
peripheralManager.stopAdvertising()Then the following delegate method is still called on device 2. func centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String: Any], rssi RSSI: NSNumber)The strange thing is that even when I connect to the device and useperipheral.discoverServices([serviceCBUUID])to ask for my service, I get an empty list. Which is ok, since I've stopped avertising on device 1, but why is the device detected at all when I explicitly ask for devices that provide my service?This only happens, when I put the app in background on device 1. If I keep it in foreground, the delegate method on device 2 is no longer called as soon as I stop advertising on device 1.I need to turn bluetooth off in settings on device 1 to stop this. Restarting the app and stopping advertising does nothing.BRDirk

Hi,was anyone able to submit a bug report using the feedback app? The data entry works, but when sending only an error message appears: "Error when sending...".So I tried the new web app (https://feedbackassistant.apple.com/) but this seems to ignore my entered text. All I get is an "Untitle Feedback" with none of the data (besides the attachements) saved.Dirk
Hello,I prepared an iPad app for running on MacOs and after a few small corretions I was able to build the app. However, it crashes right on startup.The function - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions is called, where I prepare a window and the root view controller in code. After the function returns, the app crashes.This is what the log looks like:2019-06-08 13:25:04.804240+0200 myApp[3865:61331] Bundle is missing UIMenuBarItemTitleAbout key.
