How to Access Items in a Set in Swift - Step by Step Examples

How to Access Items in a Set in Swift ?

To access items in a set in Swift, you can use iteration or specific methods provided by the Set class.

In this example,

We create a Set named stringSet containing strings.
We use a for loop to iterate over the elements in the set and print each element.

var stringSet: Set<String> = ["Apple", "Banana", "Orange", "Grapes"]

for item in stringSet {
    print(item)
}

Apple
Banana
Orange
Grapes

In this example,

var numberSet: Set<Int> = [1, 2, 3, 4]

print("Number of elements: \(numberSet.count)")
print("Does set contain 3? \(numberSet.contains(3))")

Number of elements: 4
Does set contain 3? true

In this tutorial, we learned How to Access Items in a Set in Swift language with well detailed examples.
