Creating Array of Dictionary in Swift

Question

I am new to Swift . I am trying to create an array of dictionary.

var items: [Dictionary<String,Int>] = []
var dict1 = ["One" : 1, "Two" : 2 ]
var dict2 = ["Three" : 3, "Four" : 4]
var dict3 = ["Five" : 5 , "Six" : 5]

items[0] = dict1
items[1] = dict2
items[2] = dict3
items

But it is not getting initialized properly. Playground shows no error but it is not taking dict2 and dict 3. What is wrong with it. Please correct me.

Answer 1

If you open the console (⇧⌘Y), you can see the error

fatal error: Array index out of range

You should use items.append(dict1) or items.insert(dict1, atIndex: 0) instead of items[0] = ... .

Answer 2

Please try

 items.append(dict1)
 items.append(dict2)
 and so on...

Answer 3

var items: [Dictionary<String,Int>] = []
var dict1 = ["One" : 1, "Two" : 2 ]
var dict2 = ["Three" : 3, "Four" : 4]
var dict3 = ["Five" : 5 , "Six" : 5]

let arrayOfDictionaries: [[String: Int]]
arrayOfDictionaries = [dict1, dict2, dict3]
