How to Remove Specific Item from a Set in Swift - Step by Step Examples

How to Remove Specific Item from a Set in Swift ?

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

In this example,

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

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

for num in numberSet {
    print(num)
}

In this example,

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

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

for str in stringSet {
    print(str)
}

banana
grape
date
apple
