How to Remove Specific Item from a Set in Swift ?

Answer

To remove a specific item from a set in Swift, you can use the remove method to delete the item from the set.



✐ Examples

1 Removing Item from Integer Set

In this example,

  1. We create a set named numberSet using the Set collection type in Swift, which contains integer values 1, 2, 3, 4, and 5.
  2. We use the remove method of numberSet to remove the item 3 from the set.
  3. Finally, we print the modified set numberSet to see the removed item.

Swift Program

var numberSet: Set<Int> = [1, 2, 3, 4, 5]
numberSet.remove(3)

for num in numberSet {
    print(num)
}

Output

1
2
4
5

2 Removing Item from String Set

In this example,

  1. We create a set named stringSet using the Set collection type in Swift, which contains string values "apple", "banana", "cherry", "date", and "grape".
  2. We use the remove method of stringSet to remove the item "cherry" from the set.
  3. Finally, we print the modified set stringSet to see the removed item.

Swift Program

var stringSet: Set<String> = ["apple", "banana", "cherry", "date", "grape"]
stringSet.remove("cherry")

for str in stringSet {
    print(str)
}

Output

banana
grape
date
apple
