Swift: Can not use NSImage .imageNamed

I am seeing imageNamed deprecated (or removed) from available options When I do the following:

       var statusImage:NSImage? = nil

       self.statusImage = NSImage .ImageNamed....

enter image description here

I have tried the Swift document provided by Apple and other placed.This seemed very trivial but could not find the solution for imageNamed. Am I missing something?

Use init(named: String!) instead: call it like NSImage(named: "foo").

The compiler automatically remaps ObjC class methods that are named as convenience constructors to work as Swift initializers. If a class method follows the naming convention of a convenience constructor (e.g. +[SomeThing thingWithFoo: bar:]), Swift remaps it to an initializer (e.g. call SomeThing(foo: aFoo, bar: aBar)). This also goes for a few methods that Apple identified as working like a convenience constructor (as in the case of imageNamed:).

In most cases, if you finish typing the class-method-style call to a convenience constructor, the compiler will give you an error that tells you how it's been remapped:

error: 'imageNamed' is unavailable: use object construction 'NSImage(named:)'

More generally, you can look at the autogenerated module "header" for an API symbol in Xcode by cmd-clicking that symbol (e.g. NSImage) in the editor, or look in Xcode's documentation viewer or the online reference docs for that API, to find the Swift syntax for using it.
