You're doing good! Just make sure you keep the capitalization of your variables consistent. I would use URL instead of Url...

let baseURL = NSURL(string:"https://api.forecast.io/forecast/\(apiKey)/")
let forecastURL = NSURL(string:"26.361857,-80.071547", relativeToURL: baseURL)
let weatherData = NSData(contentsOfURL:forecastURL!, options:nil, error:nil)
