iOS Build a Weather App with Swift (Retired) Pulling Data From the Web Making a Network Call

When running the app it returns nil

I have looked through some of the previous questions and answers and looking at my code I can't see what is wrong with it.

When running it in a playground it still returns nil but looking at the Console Output there seems to be an issue in that the HTTP load failed.

private let apiKey = "2d4c1bdf29ae4484a321809f17582e8a"

override func viewDidLoad() {
    // Do any additional setup after loading the view, typically from a nib.

    let baseURL = NSURL(string: "https://api.forecast.io/\(apiKey)/")

    let forecastURL = NSURL(string: "51.620345,0.045681", relativeToURL: baseURL)

    let weatherData = NSData(contentsOfURL: forecastURL!, options: nil, error: nil)


Any ideas?

the forecast API docs state that an api call looks like this:


as you can see, your base URL is:


you are missing the /forecast/ part of the URL. add that into your base URL:

let baseURL = NSURL(string: "https://api.forecast.io/forecast/\(apiKey)/")

Thank you Stone. I had the same exact issue.

Whoa man. Thanks Stone.

I knew it would be something silly like that! I did have it working earlier, I must have removed it at some point.

Thanks again.
