Problem with Xcode - Making a Simple Weather app in Swift

Hi, I am getting error messages back from Xcode on the "humidity" and "precipProbability" lines that say that I am using an unresolved identifier in the case of "precip" and that Int is not convertible to Double. Can anyone please help?

import Foundation

struct Curret {

    var currentTime: Int
    var temperature: Int
    var humudity: Double
    var precippossibility: Double
    var summary: String
    var icon: String


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

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

}
}

Hi Jason

just a few minor issues.. 

  var currentTime: Int
    var temperature: Int
    var humudity: Double   // you have it listed as a Double
    var precippossibility: Double  // you have a lowercase P here 
    var summary: String
    var icon: String

//Currently you have the following listed
        currentTime = currentWeather["time"] as Int
        temperature = currentWeather["temperature"] as Int
        humudity = currentWeather["humidity"] as Int // you have it listed as a int not a Double
        precipprobability = currentWeather["precipProbability"] as Double
        summary = currentWeather["summary"] as String
        icon = currentWeather["icon"] as String

// It should look like this.....
        currentTime = currentWeather["time"] as Int
        temperature = currentWeather["temperature"] as Int
        humudity = currentWeather["humidity"] as Double
        precippossibility = currentWeather["precipProbability"] as Double
        summary = currentWeather["summary"] as String
        icon = currentWeather["icon"] as String
