在 macOS 中将正在运行的应用程序添加到选择器

Question

我想获取 macOS 上所有正在运行的应用程序并将它们添加到 Picker 视图，但我不知道该怎么做。

Picker(selection: $stopAppTerminate.onChange(StopAppTerminateChange), label: Text("Wait for App Termination ")) {
                var workspace = NSWorkspace.shared
                var applications = workspace.runningApplications
                var i: Int = 0

                ForEach(applications) { application in //, id: \.localizedName) { application in
                    Text(String(application)).tag(i + 1)
                }
            }

但是 ForEach 循环无法通过“在对初始化程序的调用中没有完全匹配”进行编译。

    @State private var selectedApp: NSRunningApplication?
    
    var body: some View {
        var workspace = NSWorkspace.shared
        var applications = workspace.runningApplications
        
        Picker("App", selection: $selectedApp) {
            Text("No selection").tag(nil as NSRunningApplication?)
            ForEach(applications, id: .bundleIdentifier) { app in
                HStack {
                    if let icon = app.icon {
                        Image(nsImage: icon)
                    }
                    Text(app.localizedName ?? "?")
                }
                .tag(app as NSRunningApplication?)
            }
        }
    }
