Saving custom objet in NSUserDefaults returning null

I am trying to save a custom object in the NSUserDefaults but it is retuing nill. I made sure that the object had values before it saves.

 func syncObjects(){
    let userDefaults = NSUserDefaults.standardUserDefaults()

    userDefaults.setValue(NSKeyedArchiver.archivedDataWithRootObject(profile), forKey: "Profile")
    userDefaults.setValue(NSKeyedArchiver.archivedDataWithRootObject(preference), forKey: "Preference")

    userDefaults.synchronize()
    print("objects synced")
}


 func getObjects(){


    if let data = NSUserDefaults.standardUserDefaults().objectForKey("Profile") as? NSData {
        profile = NSKeyedUnarchiver.unarchiveObjectWithData(data) as! UserProfile
        if  profile.firstName == nil {
            print("Profile object reset in app delegate")
            profile.reset()
        }
    }

    if let data = NSUserDefaults.standardUserDefaults().objectForKey("Preference") as? NSData {
        preference = NSKeyedUnarchiver.unarchiveObjectWithData(data) as! UserPreference
    }
    print("retrieved objects")
}

In the custom object controller

- (void)encodeWithCoder:(NSCoder *)aCoder{
    [aCoder encodeObject:self.theID forKey:@"theID"];
    [aCoder encodeObject:self.fbID forKey:@"fbID"];
    [aCoder encodeObject:self.email forKey:@"email"]; 
}

-(id)initWithCoder:(NSCoder *)aDecoder{
    if(self = [super init]){
        self.theID = [aDecoder decodeObjectForKey:@"theID"];
        self.fbID = [aDecoder decodeObjectForKey:@"fbID"];
        self.email = [aDecoder decodeObjectForKey:@"email"];
    }
    retu self;
}
