Is there a way to manipulate NSUserDefaults stored information

I have stored a dictionary into NSUserDefaults like this:

standardDefaults.setObject(switchStater, forKey: "startUp") the switchStater object is the dictionary that stores the rowIndex and the Bool value for each UISwitch. I can print out the information that is stored in the NSUserDefaults like this:

let test = standardDefaults.objectForKey("startUp")
        print(test)

This is how I confirm the data is stored properly. I put the .setObject in the sublass of the UITableViewController because the subclass writes theUISwitch when they are manipulated. I then call the .objectForKey in the viewDidLoad of the superclass.

Is there a way to test the NSUserDefault stored with a for init loop if not how can I test the test so the UISwitch is in the position it was left after the user reloads the app?

Thanks for the help.

You can retrieve the stored Dictionary from NSUserDefaults with userDefaults.dictionaryForKey("startUp") then loop through the key/values in the dictionary and set the UISwitch appropriately like this:

let dictionary = userDefaults.dictionaryForKey("startUp")!

for (key, value): (String, AnyObject) in dictionary {
    let switch = value as! UISwitch
    print(key)
    print(switch.on)
}
