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

For Swift 3:

let data = try PropertyListSerialization.data(fromPropertyList: authResponse, format: PropertyListSerialization.PropertyListFormat.binary, options: 0)
