Why I can't access an element of a class instance in Swift

I'm currently writing an iPhone application in Swift. I have a global class instance of my user database, like this: 

var currentUser = UserDB()

class UserDB: Object {
dynamic var id:String = "0"

override class func primaryKey() -> String {
    return "id"
}

var userName: String?
var firstName: String?
var lastName: String?
}

Then I try to print my user info with a print in another class: 

UserDB {
id = 56826e22971f34731a07ba09;
userName = aze;
firstName = (null);
lastName = (null);
}

But if I try to print a single value, it won't works: 

print(currentUser.userName)

Will print: 

nil

Do you have any idea why?

By the way, is it a good idea to deal with user info like this? I put these info inside a Realm database on exit, when going to background, or after account upgrade.

You need to declare the properties as dynamic if you want Realm to map them. It seems that you did this only for the id property.

dynamic var userName: String?
dynamic var firstName: String?
dynamic var lastName: String?
