UIView background color in Swift

Question

Is there a way to set the UIView background color with Swift   I know that in Objective-C  you would use self view backgroundColor    UIColor redColor    but that does not work the same way in Swift  I have looked around and because Swift is only about a week old  I cannot find an answer   Does anyone have any suggestions

Try This  It worked like a charm  for me   The simplest way to add backgroundColor programmatically by using ColorLiteral   You need to add the property ColorLiteral  Xcode will prompt you with a whole list of colors in which you can choose any color  The advantage of doing this is we use lesser code  add HEX values or RGB  You will also get the recently used colors from the storyboard   Follow steps    1  Add below line of code in viewDidLoad      self view backgroundColor   ColorLiteral   and clicked on enter button    2  Display square box next to        3  When Clicked on Square Box Xcode will prompt you with a whole list of colors which you can choose any colors also you can set HEX values or RGB    4  You can successfully set the colors      Hope this will help some one to set backgroundColor in different ways

If you want to set your custom RGB color try this  self view backgroundColor   UIColor red  20 255 0  green  106 255 0  blue  93 255 0  alpha  1   Don t forget to keep  255 0 for every color
