How to Use Sets in Swift

How to Use Sets in Swift

The complete guide to Swift Sets. We can add an element to our Set in swift using the insert function. This will only insert if the elements don't exist already.

Sets are basically a collection of items that aren’t ordered but are unique. Let's go over different operations/functions that Swift has when it comes to Sets.

Creating a Set

Initialize an empty set

Sets in Swift are of a generic nature, so they can hold any type if it conforms to the Hashable Protocol. For the sake of simplicity, we will use String and Int.

var fruits = Set<String>()

Initialize a set with elements

We can also initialize a set with some default elements.

var fruits:Set<String> = ["apple","mango","guava"]

Initialize a set with a capacity

We can set a space pre-allocated for a minimum number/capacity.

var fruits = Set<String>(minimumCapacity: 2)
