UILabels not updating for Weather App.

For some reason the simple weather app is not updating the labels. It's just staying as the default Label text that I've set.

ViewController:

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var currentTemperatureLabel: UILabel?
@IBOutlet weak var currentHumidityLabel: UILabel?
@IBOutlet weak var currentPrecipitationLabel: UILabel?


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

    if let plistPath = NSBundle.mainBundle().pathForResource("CurrentWeather", ofType: "plist"),
        let weatherDictionary = NSDictionary(contentsOfFile: plistPath),
    let currentWeatherDictionary = weatherDictionary["Currently"] as? [String: AnyObject]{

        let currentWeather = CurrentWeather(weatherDictionary: currentWeatherDictionary)

        currentTemperatureLabel?.text = "\(currentWeather.temperature)º"
        currentHumidityLabel?.text = "\(currentWeather.humidity)%"
        currentPrecipitationLabel?.text = "\(currentWeather.precipProbability)%"

    }
}

CurrentWeather Class:

import Foundation

struct CurrentWeather {

let temperature: Int
let humidity: Int
let precipProbability: Int
let summary: String

init(weatherDictionary: [String: AnyObject]) {
    temperature = weatherDictionary["temperature"] as! Int
    humidity = weatherDictionary["humidity"] as! Int
    precipProbability = weatherDictionary["precipProbability"] as! Int
    summary = weatherDictionary["summary"] as! String
}

}

I don't understand what I'm doing wrong. Any help would be greatly appreciated.

EDIT: Even after turning the Precipitation Chance & Humidity into Doubles, it still does not update Labels. Temp: 90 | Humidity: 88% | Precip: 88%

I think I found it.

You have "let currentWeatherDictionary = weatherDictionary["Currently"] as? [String: AnyObject]"

It needs to be "let currentWeatherDictionary = weatherDictionary["currently"] as? [String: AnyObject]"

Difference is c vs C

Trick,

It's been a few months sense I have looked at this app. I don't remember pulling weather data from a plist. Can you tell me what part of the course you are on so I can take a look.

P.S You can also check out my finished app on github and compare the two. https://github.com/Mav3r1ck/Project-RainMan

Hey Aaron, Thanks for your reply, you were the first person on the list of people to ask, and I truly appreciate your "swift"ness ;)

The course I'm on is "Build a Weather App With Swift", and my issue occurred during "Simple Data Structures". I thought I followed everything to a point, but for some reason my Labels are not updating.

And I'm 100% sure my outlets are connected to the labels because of the circle in the gutter with the dot inside of it.

I'm going to take a look at your app though. Thanks :)

Trick,

I'll take a look at the course and let you know what I find.

Thanks a lot.

Looking at your app, both our CurrentWeather's are identical (besides a few name changes). That's where I thought the issue would be, but they're identical.

Your ViewController is more advanced than mine, but I'm looking at Pasan's code at the part I'm currently on, and it's identical.

If it helps, in the beginning of the lesson, when he tried to run the app he got one of the "green" errors (and his app crashed) that showed up on his AppDelegate, whereas I did not, and my app finished building.
