Using External Classes method as action for NSMenuItem?

Question

First time poster and very novice swift user. I've came up against a problem of using an external classes method as an action for a NSMenuItem. I've set up a new class called NewDocument have the method newDoc.

I want to use this method as an action for a NSMenuItem. However, when I use it, the menu item is greyed out? Even when I set the target to NewDocument, it still wont work.

Any guidance or help would be very much appreciated.

//Creating Instance of class
let createNewDocument = NewDocument()

//Use selector to declare method as action
let menuItem = NSMenuItem(title: "New", action: #selector(createNewDocument.newDoc), keyEquivalent: "")

//Set target to new instance of class
menuItem.target = createNewDocument

NewDocument Class

class NewDocument: NSObject {
    @objc func newDoc() {
        // new document logic
    }
}

Answer 1

• The target is the instance of the class – createNewDocument
• The selector is the type + method – #selector(NewDocument.newDoc)
