In xcode 8 you can directly choose image from the selection window  NEW       You just need to type -  image  and you will get a suggestion box then select - Image Literal  from list  see in attached picture   and then tap on the square you will be able to see all images see in second attached picture  which are in your image assets    or select  other image from there       Now tap on square box -  You will see that square box after selecting above option

Since you have your bgImage assigned and linked as an IBOutlet  there is no need to initialize it as a UIImageView    instead all you need to do is set the image property like bgImage image   UIImage named   afternoon    After running this code  the image appeared fine since it was already assigned using the outlet     However  if it wasn t an outlet and you didn t have it already connected to a UIImageView object on a storyboard xib file  then you could so something like the following     class ViewController  UIViewController       var bgImage  UIImageView       override func viewDidLoad             super viewDidLoad            var image  UIImage   UIImage named   afternoon            bgImage   UIImageView image  image          bgImage  frame   CGRectMake 0 0 100 200          self view addSubview bgImage

You just need to drag and drop an ImageView  create the outlet action  link it  and provide an image  Xcode is going to look in your assets folder for the name you provided  here   toronto     In yourProject ViewController swift  import UIKit  class ViewController  UIViewController         IBOutlet weak var imgView  UIImageView       override func viewDidLoad             super viewDidLoad            imgView image   UIImage named   toronto

This code is in the wrong place   var image   UIImage   UIImage named  afternoon    bgImage   UIImageView image  image  bgImage frame   CGRect x  0  y  0  width  100  height  200  view addSubview bgImage    You must place it inside a function  I recommend moving it inside the viewDidLoad function    In general  the only code you can add within the class that s not inside of a function are variable declarations like    IBOutlet weak var bgImage  UIImageView

If you want to do it the way you showed in your question  this is a way to do it inline  class YourClass  UIViewController      IBOutlet weak var tableView  UITableView      other IBOutlets      THIS is how you declare a UIImageView inline   let placeholderImage   UIImageView             let placeholderImage   UIImageView image  UIImage named   nophoto            placeholderImage contentMode    scaleAspectFill         return placeholderImage             var someVariable  String     var someOtherVariable  Int      func someMethod            method code            and so on
