1,476 Pointsprintln(repsonse) is Nil. How to get NSData(contentsOfURL : forecastURL!) to work
I don't think the code is wrong because it compiles successfully, but there is no data inside of the URL according to the console.
println(response) //displays "nil"
private let apiKey = "apikey"
let baseURL = NSURL(string: "https://api.forecast.io/forecast/\(apiKey)/")
let forecastURL = NSURL(string: "40.724245,-73.562374", relativeToURL: baseURL)
let sharedSession = NSURLSession.sharedSession()
let downloadTask:NSURLSessionDownloadTask = sharedSession.downloadTaskWithURL(forecastURL!, completionHandler:
{(
location:NSURL!,
response:NSURLResponse!,
error: NSError!)
-> Void in
println(response)
})
downloadTask.resume()
Please help. Thank you

Courses Plus Student 29,439 PointsA good practice is to also output the error that comes back into that completion handler. This way you don't have to wait until a connection will go through and you receive some actual data.
By checking the error message if it's nil or not will also give you the opportunity to inform the user that something went wrong and they have to refresh or try fetching the data again.
