swift - change color of top UIToolbar border

Question

I'm trying to change the color of the top border on a UIToolbar.

I tried:

layer.borderWidth = 1
layer.borderColor = UIColor(r: 250, g: 250, b: 250).CGColor

That didn't work.

Suggestions? Thank you

I've done it using this code:

class ViewController: UIViewController {
  
  @IBOutlet weak var toolBar: UIToolbar!
  
  override func viewDidLoad() {
    super.viewDidLoad()
    
    // the layer with the width of the device
    // and height of 0.5 px
    let topBorder = CALayer()
    topBorder.frame = CGRectMake(0, 0, view.frame.size.width, 0.5)
    topBorder.backgroundColor = UIColor.redColor().CGColor
    
    // adding the layer to the top
    // of the toolBar
    toolBar.layer.addSublayer(topBorder)
  }
}

Result:
