Ordered map in Swift

Question

Is there any built-in way to create an ordered map in Swift 2? Arrays [T] are sorted by the order that objects are appended to it, but dictionaries

Answer 1

Here's what I did, pretty straightforward:

let array = [
    ["foo": "bar"],
    ["foo": "bar"],
    ["foo": "bar"],
    ["foo": "bar"],
    ["foo": "bar"],
    ["foo": "bar"]
]

// usage
for item in array {
    let key = item.keys.first!
    let value = item.values.first!

    print(key, value)
}

Keys aren't unique as this isn't a Dictionary but an Array but you can use the array keys.
