App crashes when internet connections gets disconnected(Grabbing the NSURL from online)

[Mattporter0]

I am using this animatedImage with a URL from online
let urlString = "URLFROMINTERNET"
let animatedImage = XAnimatedImage(initWithAnimatedGIFData: NSData(contentsOfURL: NSURL(string: urlString!)!)!)

Everything is good, but if I was to put the app into aeroplane mode and scroll though the tableview where the animated image is displayed it will crash with the error
fatal error: unexpectedly found nil while unwrapping an Optional value

Any ideas how to stop this?

Hi Matt,

Theoretically, without replicating the error (which I will get to later) I believe that the optional value should fail gracefully which doesn't seem to be the case currently. I'm certain it will require 'optional chaining' rather than forced unwrapping as mentioned here.

However, as a current workaround let me refer to this Reachability class. This will detect the iPhone connectivity status and could be used to guard against any potential nil values.

Keep in mind that its a suggestion and not foolproof. I offer it in case you are under tight time constraints.
