I'm getting an error when building the app after I wrote the dispatch_async lines. The app stops building pointing to an error at the bracket under the downloadTask.resume() line. In the debug area, if I press the "Continue program execution" the app runs normally and the error disappears.
My code is as follows:
import UIKit
class ViewController: UIViewController {
@IBOutlet weak var iconView: UIImageView!
@IBOutlet weak var currentTimeLabel: UILabel!
@IBOutlet weak var humidityLabel: UILabel!
@IBOutlet weak var precipitationLabel: UILabel!
@IBOutlet weak var summaryLabel: UILabel!
@IBOutlet weak var temperatureLabel: UILabel!
private let apiKey = "4de5319c1c8991a1ff2985013795b0b3"
override func viewDidLoad() {
super.viewDidLoad()
let baseURL = NSURL(string: "https://api.forecast.io/forecast/\(apiKey)/")
let forecastURL = NSURL(string: "37.8267,-122.423", relativeToURL: baseURL)
let sharedSession = NSURLSession.sharedSession()
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
let currentWeather = Current(weatherDictionary: weatherDictionary)
dispatch_async(dispatch_get_main_queue(), { () -> Void in
self.temperatureLabel.text = "\(currentWeather.temperature)"
self.iconView.image = currentWeather.icon!
self.currentTimeLabel.text = "At \(currentWeather.currentTime!) it is"
self.humidityLabel.text = "\(currentWeather.humidity)"
self.precipitationLabel.text = "\(currentWeather.precipProbability)"
self.summaryLabel.text = "\(currentWeather.summary)"
})
}
})
downloadTask.resume()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}

7,468 PointsI found the problem, it wasn't an error with the code, the "toggle global breakpoint state" button was "ON" and was holding the code from executing from the start till the end. Thank you Nejc
