4,442 PointsiOS Weather APP project files broken
It seems that XCode has been updated since the release of this guide. As a result, the provided project files for this part of the course all fail to build. Does anyone have a fix for this, as I've tried and failed.
The error seems to reside in this block of code:
let downloadTask: NSURLSessionDownloadTask = sharedSession.downloadTaskWithURL(forecastURL, completionHandler: { (location: NSURL!, response: NSURLResponse!, error: NSError!) -> Void in
if (error == nil) {
let dataObject = NSData(contentsOfURL: location)
let weatherDictionary: NSDictionary = NSJSONSerialization.JSONObjectWithData(dataObject, options: nil, error: nil) as NSDictionary
I get the error "Value of NSURL? not unwrapped, did you mean to use ! or ?"
Any help would be appreciated and obviously the treehouse guys need to fix the project files as the update was quite a while back now.
Cheers
Lewis
