Swift 3  If you want rounded label with background color  in addition to most of the other answers  you need to set layer s background color as well  It does not work when setting view background color   label layer cornerRadius   8 label layer masksToBounds   true label layer backgroundColor   UIColor lightGray cgColor   If you are using auto layout  want some padding around the label and do not want to set the size of the label manually  you can create UILabel subclass and override intrinsincContentSize property   class LabelWithPadding  UILabel       override var intrinsicContentSize  CGSize           let defaultSize   super intrinsicContentSize         return CGSize width  defaultSize width   12  height  defaultSize height   8            To combine the two you will also need to set label textAlignment   center  otherwise the text would be left aligned

Works fine in Xcode 8 1 2 with Swift 3   cornerRadius is the key property to set rounded edges  If you are using the same style for all labels in your application  I would recommend for an extension method  Code      extension Class extension UILabel           extension user defined Method     func setRoundEdge             let myGreenColor    UIColor red  -0 108958  green  0 714926  blue  0 758113  alpha  1 0             Width of border         self layer borderWidth   1 0           How much the edge to be rounded         self layer cornerRadius   5 0             following properties are optional           color for border         self layer borderColor   myGreenColor cgColor           color for text         self textColor   UIColor red            Mask the bound         self layer masksToBounds   true           clip the pixel contents         self clipsToBounds   true          Output   Why Extension method  Create a Swift file and add the following code  which has the Extention method to the  quot UILabel quot  class  where this method is user defined but will work for all the label in your application and will help to maintain consistency and clean code  if you change any style in future require only in the extension method

iOS 3 0 and later  iPhone OS 3 0 and later supports the cornerRadius property on the CALayer class  Every view has a CALayer instance that you can manipulate  This means you can get rounded corners in one line   view layer cornerRadius   8    You will need to  import  lt QuartzCore QuartzCore h gt  and link to the QuartzCore framework to get access to CALayer s headers and properties   Before iOS 3 0  One way to do it  which I used recently  is to create a UIView subclass which simply draws a rounded rectangle  and then make the UILabel or  in my case  UITextView  a subview inside of it  Specifically    Create a UIView subclass and name it something like RoundRectView  In RoundRectView s drawRect  method  draw a path around the bounds of the view using Core Graphics calls like CGContextAddLineToPoint   for the edges and and CGContextAddArcToPoint   for the rounded corners  Create a UILabel instance and make it a subview of the RoundRectView  Set the frame of the label to be a few pixels inset of the RoundRectView s bounds   For example  label frame   CGRectInset roundRectView bounds  8  8      You can place the RoundRectView on a view using Interface Builder if you create a generic UIView and then change its class using the inspector  You won t see the rectangle until you compile and run your app  but at least you ll be able to place the subview and connect it to outlets or actions if needed
