iOS Build a Weather App with Swift (Retired) Data Modeling With Structures Cleaning Up Our Date

Receiving 'Any Object?' is not convertible to ' NSDictionary'

Swift is suggesting I downcast the first line to

let currentWeather = weatherDictionary["currently" as! NSDictionary.

However, when I downcast that I get erros for the rest of the "as" instances...

CURRENT CODE:

let currentWeather = weatherDictionary["currently"] as NSDictionary

    currentTime = currentWeather["time"] as Int
    temperature = currentWeather["temperature"] as Int
    humidity = currentWeather["humidity"] as! Double
    precipProbability = currentWeather["precipProbability"] as Double
    summary = currentWeather["summary"] as String
    icon = currentWeather["icon"] as String

Any luck with this? Found myself in the same situation just now. I'm pretty sure it's an issue with the line:

let downloadTask: NSURLSessionDownloadTask = sharedSession.downloadTaskWithURL(forecastURL, completionHandler:...

xCode keeps prompting me to force a downcast on forecastURL with the syntax:

forecastURL!

which I think ultimately forces the dataObject to have a problem.

Not sure how to proceed.

Dang. I am getting the same thing. Did you happen to figure it out?

Try adding ! with each as. I reckon this has changed when xcode was updated. My code:

init(weatherDictionary: NSDictionary) {
        let currentWeather = weatherDictionary["currently"] as! NSDictionary

        currentTime = currentWeather["time"] as! Int
        temperature = currentWeather["temperature"] as! Int
        humidity = currentWeather["humidity"] as! Double
        precipProbability = currentWeather["precipProbability"] as! Double
        summary = currentWeather["summary"] as! String
        icon = currentWeather["icon"] as! String

    }

I found you need to unwrap each value in that statement not just forecastURL

let downloadTask: NSURLSessionDownloadTask = sharedSession.downloadTaskWithURL(forecastURL!, completeHandler: { (location: NSURL!, response: NSURLRespones!, error: NSError!) ->Void
