How do I write a function that gets a Dictionary?

Hi,

I am trying to write a function that gets a Dictionary as a parameter and then make to this Dictionary changes in my function.

But when I type :

func dictonaryTuple(Dictonary: Dictionary) -> Dictionary<Int,Double>

It dose't work and the Xcode says that there is a problem.

Can someone please help me ?

Thank you very much ! :)

without knowing the context, i would go for a struct...

Like so:

struct MyStruct {

    var valueOne: String
    var valueTwo: Int
    var valueThree: Double

    init(myDictionary: NSDictionary) {
        let newDictionary = myDictionary["dictionary"] as NSDictionary
        valueOne = newDictionary["keyOne"] as String
        valueTwo = newDictionary["keyTwo"] as Int
        valueThree = newDictionary["keyThree"] as Double
    }
}

YOUR example would normally be written like this:

func dictonaryTuple(Dictonary: NSDictionary) -> NSDictionary {

    // Your Code here

    return Dictonary
}

I hope this helps
