Initialising empty arrays of dictionaries in Swift

You need to give types to the dictionaries:

var myNewDictArray: [Dictionary<String, Int>] = []

or

var myNewDictArray = [Dictionary<String, Int>]()

Edit: You can also use the shorter syntax:

var myNewDictArray: [[String:Int]] = []

or

var myNewDictArray = [[String:Int]]()

This will create an empty, immutable dictionary:

let dictionary = [ : ]

And if you want a mutable one:

var dictionary = [ : ]

Both of these dictionaries default to Dictionary<String?, AnyObject?>.

The reason this isn't working:

var myNewDictArray: Dictionary[] = []

is that you need to provide types for the keys and values of a dictionary when you define it. Each of these lines will create you an empty array of dictionaries with string keys and string values:

var dictArray1: Dictionary<String, String>[] = Dictionary<String, String>[]()
var dictArray2: Dictionary<String, String>[] = []
var dictArray3 = Dictionary<String, String>[]()
