UIFont returning nil for custom font

I am trying to use the Nunito-ExtraBoldItalic font for my UILabel.

I followed the steps outlined in tutorials and other answers.

1. Add font to fonts folder. Made sure the target is set to the project.
2. Add the entry to plist.
3. Made sure the font is shown in build phase/copy bundle resources. It is shown.

I am using the following code to create a UIlabel:

uiLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 160, height: 50))
let myfont = UIFont(name: "Nunito-ExtraBoldItalic", size: 14)
uiLabel!.font = myfont
uiLabel!.textColor = UIColor(red: CGFloat(51/255.0), green: CGFloat(33/255.0), blue: CGFloat(32/255.0), alpha: CGFloat(100.0))
addSubview(uiLabel!)

But UIFont returns nil.

Postscript name of font is "Nunito-ExtraBoldItalic".

I also tried running the following:

    for familyName:String in UIFont.familyNames {
        print("Family Name: \(familyName)")
        for fontName:String in UIFont.fontNames(forFamilyName: familyName) {
            print("--Font Name: \(fontName)")
        }
    }

My font is not shown.

The font is visible in storyboard and other areas.

I tried using the Nunito-ExtraBoldItalic, Nunito-ExtraBold Italic, Nunito-ExtraBold-Italic as names. None worked.

So I am not sure what the problem is.
