Sí, la clave es aplicar un valor negativo al NSStrokeWidthAttributeName Si este valor es positivo, solo verá el trazo y no el relleno.

Objetivo-C: 

self.label.attributedText=[[NSAttributedString alloc] 
initWithString:@"string to both stroke and fill" 
attributes:@{
             NSStrokeWidthAttributeName: @-3.0,
             NSStrokeColorAttributeName:[UIColor yellowColor],
             NSForegroundColorAttributeName:[UIColor redColor]
             }
];

Versión swift: 

let attributes = [NSStrokeWidthAttributeName: -3.0,
                      NSStrokeColorAttributeName: UIColor.yellowColor(),
                      NSForegroundColorAttributeName: UIColor.redColor()];

label.attributedText = NSAttributedString(string: "string to both stroke and fill", attributes: attributes)

Swift 3 versión:

    let attributes = [NSStrokeWidthAttributeName: -3.0,
                      NSStrokeColorAttributeName: UIColor.yellow,
                      NSForegroundColorAttributeName: UIColor.red] as [String : Any]

    label.attributedText = NSAttributedString(string: "string to both stroke and fill", attributes: attributes)

Swift 4 versión:

let attributes: [NSAttributedStringKey : Any] = [.strokeWidth: -3.0,
                                                 .strokeColor: UIColor.yellow,
                                                 .foregroundColor: UIColor.red]

label.attributedText = NSAttributedString(string: text, attributes: attributes)

Ahora Más tarde en swift apple, elimine la [Cadena: Any] para la declaración de valor de la clave de atributos use como [NSAttributedStringKey: Any] 

    let strokeTextAttributes = [
        NSAttributedStringKey.strokeColor : UIColor.green,
        NSAttributedStringKey.foregroundColor : UIColor.lightGray,
        NSAttributedStringKey.strokeWidth : -4.0,
        NSAttributedStringKey.font : UIFont.boldSystemFont(ofSize: 52)
        ] as [NSAttributedStringKey : Any]

    hello_cell_lb.attributedText = NSAttributedString(string: "\(hello_array[indexPath.row])", attributes: strokeTextAttributes)
