I'm building a source editor extension and when it gets triggered I want to show an alert.

I tried this:

let alert = NSAlert()
alert.messageText = "Hello world"
alert.informativeText = "Information text"
alert.addButton(withTitle: "OK")
alert.addButton(withTitle: "Cancel")
alert.runModal()

But I get this error:

Exception: NSWindow drag regions should only be invalidated on the Main Thread! NSWindow drag regions should only be invalidated on the Main Thread!

Thank you in advance

have you tried DispatchQueue ? – Mohmmad S Feb 18 '19 at 11:25
Yes I put it in this code DispatchQueue.main.async { } but I get the same error – mike vorisis Feb 18 '19 at 11:28
I managed to get the alert with DispatchQueue.main.async but the Alert will be displayed under the Editor in XCode. – Thomas Quester Oct 06 '20 at 15:49
