How do you open 2 windowgroups from SwiftUI button on macOS?-CodePudding

I have an app where I have a need where a button will open two windows. In the App struct I have the two window groups setup

@main
struct myApp: App {

  var body : some Scene {

      WindowGroup() {
         WelcomeView()
      }

      WindowGroup("FirstViewGroup") {

        FirstView()
        
      }
      .handlesExternalEvents(matching: Set(arrayLiteral: "FirstViewGroup"))

      WindowGroup("SecondViewGroup") {
        SecondView()
      }
      .handlesExternalEvents(matching: Set(arrayLiteral: "SecondViewGroup"))
  }
}

In the WelcomeView I have the following button action:

Button {
   if let firstURL = URL(string: "myApp://FirstViewGroup"), let secondURL = URL(string: "myApp://SecondViewGroup") {
      NSWorkspace.shared.open(firstURL)
      NSWorkspace.shared.open(secondURL)
   }
} label: {
  Text("Open Windows")
}

When I comment out one of the NSWorkspace.shared.open lines in the button action, the appropriate window opens. But when I have two sequential NSWorkspace.shared.open calls, I only get the first. Ideas? I have the URL Types in info.plist set correctly (since each window opens successfully when each is called individually)

CodePudding user response：

Try to open second URL in next event loop, like

Button {
   if let firstURL = URL(string: "myApp://FirstViewGroup"), let secondURL = URL(string: "myApp://SecondViewGroup") {
      NSWorkspace.shared.open(firstURL)
      DispatchQueue.main.async {
         NSWorkspace.shared.open(secondURL)   // << here !!
      }
   }
} label: {
  Text("Open Windows")
}
