Happy to help, this code is a bit old so thank you for checking it still works :)
Very cool! For me the window wouldn't open unless:
DispatchQueue.main.async {
NSApplication.shared.setActivationPolicy(.regular)
NSApplication.shared.activate(ignoringOtherApps: true)
}
App.main()
Thanks! Yeah I haven't re-ran this in some time so it probably is a bit out of date.
You shouldn't need to run NSApplication.shared.setActivationPolicy(.regular) inside an async block. I'd also recommend running NSApplication.shared.activate() inside an onAppear modifier attached to a view, rather than in an async block
That actually works really well other than the input not working.
never mind, it works, I had the dumb
Oh, no not the dumb! Glad folks are still finding this useful!
It's very useful. I was wondering if you'd ever played around with setting it up to take multiple parameters that might be of different types, so like:
swift-ui-commandline-tool -myInt -"myString"?
Swift argument parser (https://github.com/apple/swift-argument-parser) is pretty good for this but it doesn’t work well with scripts. Some attempts have been made to add functionality to make this work better but as far as I know nothing has landed in the tool chain.
This is amazing. Thank you!
