View border Color not changing

Question

I have a view I make border with this run time attributes:

The problem is layer.borderColor when I set borderColor my border is gone but when I don't set border Color I have a black border which I don't want any ideas?

Answer 1

You are facing this issue because layer.borderColor want CGColor and from User defined runtime attributes you can only set UIColor not CGColor, when you don't set the color it will take default borderColor and i.e black color. To set borderColor you need to set it programmatically like this.

Swift 3

yourView.layer.borderColor = UIColor.red.cgColor //set your color here

Swift 2.3 or lower

yourView.layer.borderColor = UIColor.redColor().CGColor //set your color here

Answer 2

In addition to what @NiravD suggested, you need to set both borderColor and the borderWidth on the view's layer to see the border.

Swift 3 & Swift 4:

circle.layer.cornerRadius = 5.0
circle.layer.borderColor = UIColor.red.cgColor
circle.layer.borderWidth = 2.0 

Answer 3

in Swift 3.0

  @IBOutlet weak var viewMainCell: UIView!

  viewMainCell.layer.shadowOpacity = 0.5
  viewMainCell.layer.shadowRadius = 5
  viewMainCell.layer.shadowColor = UIColor.black.cgColor
  viewMainCell.layer.cornerRadius = 5
  viewMainCell.layer.masksToBounds = false
