NSDictionary to NSData and NSData to NSDictionary in Swift

Question

I am not sure if I am using the dictionary or the data object or both incorrectly. I m trying to get used to the switch to swift but I\'m having a little trouble.

Answer 1

Leo's answer gave me build time errors because NSData isn't the same as Data. The function unarchiveObject(with:) takes a variable of type Data, whereas the function unarchiveTopLevelObjectWithData() takes a variable of type NSData.

This is a working Swift 3 answer:

var names : NSDictionary = ["name":["John Smith"], "age": 35]
let namesData : NSData = NSKeyedArchiver.archivedData(withRootObject: names) as NSData
do{
    let backToNames = try NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(namesData) as! NSDictionary
    print(backToNames)
}catch{
    print("Unable to successfully convert NSData to NSDictionary")
}
