How to Access Items in a Set in Swift


How to Access Items in a Set in Swift ?

Answer

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



✐ Examples

1 Access Items in a Set using Iteration

In this example,

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

Swift Program

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

for item in stringSet {
    print(item)
}

Output

Apple
Banana
Orange
Grapes

2 Access Items in a Set using Specific Methods

In this example,

  1. We create a Set named numberSet containing integers.
  2. We use the contains method to check if an item exists in the set.
  3. We use the count property to get the number of elements in the set.

Swift Program

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

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

Output

Number of elements: 4
Does set contain 3? true

Summary

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