I have a macOS app window where I present a sheet that lets a user login to a server. When the user selects the cancel login option, I would like the sheet to be dismissed and the hosting window closed. I know how to dismiss the sheet. How do I close the window?

If you have defined

Code Block     let myWindow:NSWindow?

then call

Code Block self.myWindow?.close()

To dismiss the sheet, 2 options:

environment var
binding to hold status of sheet

This only works if I create my own window. I am relying on the SwiftUI app's default create window function. There is another suggestion in the link where

Code Block 	NSApplication.shared.keyWindow?.close()

is suggested. This works.

You can use the dismiss environment value.

@Environment(\.dismiss) var dismiss
