Can't get around unwrapped value for icons

var iconImage = UIImage(named: imageName) 
return iconImage

Throws me an error at return iconImage that you need to unwrap it although that is not the case in the video. I can unwrap the value by using return iconImage! but then it returns nil value. Everything else works just fine in later on videos. It is returning the correct string from dictionary for stringIcon.

Thanks but turns out data for icon from forecast.io were not coming up right which were causing the issue but I have fixed that so it is working now. Something to note is that in the video value is not unwrapped for return iconImage which will still throw an error so just add ! after it.

Edited on 11/19/2014 I was wrong in saying that forcast.io were not coming up right. They were coming up right but just returning a nil value specifically for partly-cloudy images which happens to be all the time in area I chose so it was a difficult to figure out the problem but there were no images for partly-cloudy in Xcode.

I had this same issue and added "!" to resolve it too. When you say "data for icon from forecast.io were not coming up right" please can you explain and give specific examples? Thanks!

I had the same issues for unwrapping iconName and I added "!" at the end of the return statement. But then after that I got following error showing up in the console:

"fatal error: unexpectedly found nil while unwrapping an Optional value (lldb) "

any ideas on that?
