Thanks, mate! Thats precisely the problem I was having. Had to do plenty of googling before I found this document https://lists.swift.org/pipermail/swift-users/Week-of-Mon-20170717/005927.html Ended up solving the issue this way:
override var windowNibName: NSNib.Name? {
return NSNib.Name(rawValue: “MainWindowController”)
}
But I like your approach too.
Btw, do you keep track of the changes they keep introducing to Swift? If you do, would you care to share with me how, for instance, have you found out about this particular issue? It was not too easy to google out this crap I must say.
