How to use custom fonts in a mac application?

I try to use custom fonts in my swift app, but they don't load.

I copy the fonts.ttf in my resources folder, and I added the names in Info.plist under "Fonts provided by application " key.

I've try with "Application fonts resource path" key from .plist , but no results. Here is the code I used to apply my font. I've try with : "MyFont.ttf" , and "MyFont"

@IBOutlet weak var label:NSTextField!

override func awakeFromNib() {
    label.font = NSFont(name: "MyFont.ttf", size: 15)
}

First add the desired font you want to embed to your OSX app to your project:

Then click project > Info, then click the plus sign and add a new key "Application fonts resource path" and type the name of your fonts there creating an array of strings:

Now you can select custom font and the name of the font will show there, you still need to use the Font Book to make it available inside Xcode.
