Can you think of a way to declare, initialize and add key-value pairs to d in a single step?

let d = ["de": "Hut""en": "Hat"]let d = ["Hut", "Hat"]let d = [Int: Int]()let d = ("Hut", "Hat")

Perfect! We can assign key-value pairs in brackets; because of type inference, d gets that it's made for string keys and values.

Almost! We can assign key-value pairs in brackets; because of type inference, d gets that it's made for string keys and values.
