No image displayed

Hi, My program is running, but no image is displayed in the Image View. The container is just orange, with nothing in it. I have added a property "iconFile" if Playlist struct, that contains the name of the file ("coffee.pdf" in our case) ... var iconFile : String ... let iconName = playListDictionary["icon"] as String! self.iconFile = iconName ... and i use a println in the viewDidLoad method to see if the dictionary is ok, which seems to be the case. ... let playList = PlayList(index: 0) playlistImageView0.image = playList.icon println(playList.iconFile) ... "coffee.pdf" appears in the debugger, at the bottom left. But the image "coffee.pdf" does not appear in the View.

Can you tell me why ? Thanks ! I really would like to fix this before going further.

Ok I have looked in the Internet and found the solution here : http://stackoverflow.com/questions/24049537/defining-the-file-a-uiimage-will-use-swift

the right parameter to create an Image with a file name is : UIImage(named: String) rather than UIImage(contentsOfFile: String)

and now it works !

thanks for your concern Greg, see U

Hi Jeanne,

I think you might want coffee.png, rather than coffee.pdf.

Let me know if that works!

Hi Greg, I'll try at home this evening, but I've pasted the exact same code as Pasan (in the "Teacher's notes" section), and it's "coffee.pdf". ++
