Dictionary

Instantiates a Dictionary<Key, Value> from an environment variable string representation where the Key and Value conform to EnvironmentStringConvertible.

Elements must be comma (,) separated and key/value pairs must be colon (:) separated in the string representation.

let numbers = [String : Int](environmentString: "one:1,two:2,three:3")
print(numbers)
// Prints "Optional(["one": 1, "three": 3, "two": 2])"

This enables setting and getting a dictionary using the Environment.

Environment.environment.NUMBERS = ["one":1,"two":2,"three":3]
// Sets a string value of "one:1,two:2,three:3"

let numbers: [String : Int]? = Environment.environment.NUMBERS
// Gets a dictionary of ["one":1,"two":2,"three":3]

The environment variable string representation.

Elements are comma (,) separated and key/value pairs are colon (:) separated.

let numbers = ["one": 1, "two": 2, "three": 3]
print(numbers.environmentString)
// Prints "one:1,two:2,three:3"
