How to create array of unique object list in Swift

Question

How can we create unique object list in Swift language like NSSet & NSMutableSet in Objective-C.

Answer 1

Swift has no concept of sets. Using NSMutableSet in Swift might be slower than using a Dictionary that holds dummy values. You could do this :

var mySet: Dictionary = [:]
mySet["something"]= 1

Then just iterate over the keys.
