Initializer

init(dictionaryLiteral:)

Creates a dictionary initialized with a dictionary literal.

Declaration

init(dictionaryLiteral elements: (Key, Value)...)

Parameters

elements

The key-value pairs that will make up the new dictionary. Each key in elements must be unique.

Discussion

Do not call this initializer directly. It is called by the compiler to handle dictionary literals. To use a dictionary literal as the initial value of a dictionary, enclose a comma-separated list of key-value pairs in square brackets.

For example, the code sample below creates a dictionary with string keys and values.

let countryCodes = ["BR": "Brazil", "GH": "Ghana", "JP": "Japan"]
print(countryCodes)
// Prints "["BR": "Brazil", "JP": "Japan", "GH": "Ghana"]"
