Save Dictionary to NSUserDefaults Swift

I have a dictionary and I want to save it to NSUserDefaults (or something else so that I can access my variables after I stopped the application), I found an example:

var saved = NSUserDefaults.standardUserDefaults()
let dict = ["Name": "Paul", "Country": "UK"]
saved.setObject(dict, forKey: "SavedDict")

But when I used it for my dictionary, it did not work. (maybe because my dictionary is a little different)

My dictionary is made as follows:

 var userDictionary = [Int : Event]()

 struct Event {
        var sensorName: String
        var sensorType: String
        var sensorSub: String

    }

And I add these elements:

userDictionary[value] = Event(sensorName: "first", sensorType: "Temp", sensorSub: "Third")

And here is what I tried to do to save it.

saved.setObject(userDictionary, forKey: "valueDictionary")

And I get this error:

Cannot convert value of type '[Int: SensorsView.Event]' to expected Type of argument 'AnyObject?'

To avoid this error, I did the following:

self.saved.setObject(self.userDictionary as? AnyObject, forKey: "valueDictionary")

But I can’t get what I saved

Realm! :

class Sensors : Object {


    dynamic var sensorName = ""
    dynamic var sensorType = ""
    dynamic var sensorSub = ""

}

:

    var useOfRealm = try! Realm() 
    var allSensors = useOfRealm.objects(Sensors.self)
    var saving = Sensors()
    func fillThis() {
    try! useOfRealm.write {

                saving.sensorName = "something"
                saving.sensorType = "something"
                saving.sensorSub = "something"

                useOfRealm.add(saving)
    }
}
