You can write an extension to use it with all the UIViews eg  UIButton  UILabel  UIImageView etc  You can customise my following method as per your requirement  but I think it will work well for you   extension UIView       func setBorder radius CGFloat  color UIColor   UIColor clearColor    - gt  UIView          var roundView UIView   self         roundView layer cornerRadius   CGFloat radius          roundView layer borderWidth   1         roundView layer borderColor   color CGColor         roundView clipsToBounds   true         return roundView           Usage   btnLogin setBorder 7  color  UIColor lightGrayColor    imgViewUserPick setBorder 10

Use  IBDesignable and  IBInspectable to do the same    They are re-useable  easily modifiable from the Interface Builder and the changes are reflected immediately in the Storyboard  Conform the objects in the storyboard to the particular class  Code Snippet    IBDesignable class CustomView  UIView    IBInspectable var borderWidth  CGFloat   0 0       didSet           self layer borderWidth   borderWidth            IBInspectable var borderColor  UIColor   UIColor clear        didSet            self layer borderColor   borderColor cgColor          override func prepareForInterfaceBuilder          super prepareForInterfaceBuilder          Allows easy modification from Interface Builder

Swift 5  I  always use view extension to make view corners round  set border color and width and it has been the most convenient way for me  just copy and paste this code and controlle these properties in attribute inspector  extension UIView        IBInspectable     var cornerRadius  CGFloat           get               return layer cornerRadius                   set               layer cornerRadius   newValue                           IBInspectable     var borderWidth  CGFloat           get               return layer borderWidth                   set               layer borderWidth   newValue                           IBInspectable     var borderColor  UIColor            get               if let color   layer borderColor                   return UIColor cgColor  color                            return nil                   set               if let color   newValue                   layer borderColor   color cgColor               else                   layer borderColor   nil
