2½ years and no-one mentioned map?

ok, set aside that Dictionary has a property values(as ameenihad shows) which will do what you asking for, you could do:

let values = dict.map { $0.value }

EDIT: Try Something like this,

var dict : [String : Array<String>] = [
                                        "Fruits" : ["Mango", "Apple", "Banana"],
                                        "Flowers" : ["Rose", "Lotus","Jasmine"],
                                        "Vegetables" : ["Tomato", "Potato","Chilli"]
                                      ]


var myArray : Array<String> = []
// You can access the dictionary(dict) by the keys(Flowers, Flowers, Vegetables)
// Here I'm appending the array(myArray), by the accessed values.
myArray += dict["Fruits"]!
myArray += dict["Vegetables"]!

print("myArray \(myArray)")

Above is how to get values of dictionay in swift, If you want to get contatenated array of all the values of dictionary(*only values), Try something like below.

print("values array : \(dict.map{$0.value}.flatMap{$0})")

values array : ["Rose", "Lotus", "Jasmine", "Tomato", "Potato", "Chilli", "Mango", "Apple", "Banana"]
