println("Dictionary key \(key) - Dictionary value \(value)")

}

When the above code is compiled and executed, it produces the following result:

Dictionary key 1 - Dictionary value One

Dictionary key 2 - Dictionary value Two

Dictionary key 3 - Dictionary value Three

You can use enumerate() function which returns the index of the item along with its
(key, value) pair as shown below in the example:

import Cocoa

var someDict:[Int:String] = [1:"One", 2:"Two", 3:"Three"]

for (key, value) in enumerate(someDict) {

println("Dictionary key \(key) - Dictionary value \(value)")

}

When the above code is compiled and executed, it produces the following result:

Dictionary key 0 - Dictionary value (1, One)

Dictionary key 1 - Dictionary value (2, Two)

Dictionary key 2 - Dictionary value (3, Three)

Convert to Arrays

You can extract a list of key-value pairs from a given dictionary to build separate arrays
for both keys and values. Here is an example:

import Cocoa

var someDict:[Int:String] = [1:"One", 2:"Two", 3:"Three"]

let dictKeys = [Int](someDict.keys)

let dictValues = [String](someDict.values)

println("Print Dictionary Keys")
