How to store and retrieve Dictionary value types in Swift

Question

I was having trouble storing a Dictionary in the NSUserDefaults, and then I had trouble retrieving the values. After a failed search on the web, I finally figured it out and so I hope this helps you with this same issue.

Answer 1

Define your variables for NSUserDefaults, Dictionary and key:

let defaults = NSUserDefaults.standardUserDefaults()
var myDictionary = Dictionary<String, Int>()
let myKey = "Key"

How to save your dictionary:

defaults.setObject(myDictionary, forKey: myKey)

How to retrieve your dictionary:

myDictionary = defaults.dictionaryForKey(myKey) as! Dictionary<String, Int>

NOTE: make sure that your data types are the same as the way you set them up.

*** FYI, this is using Xcode 6.3.2
