How to Copy a Set in Swift ?

Answer

In Swift, sets are value types, so when you assign a set to another variable, you create a copy of the set by default.

✐ Examples

1 Copy Integer Set

In this example,

We create a set named numbers containing some integer elements.
We assign numbers to a new variable named copiedNumbers.
Now, copiedNumbers contains a copy of all elements from numbers.

Swift Program

let numbers: Set<Int> = [1, 2, 3, 4, 5]
let copiedNumbers = numbers

print("Copied Numbers:")
for number in copiedNumbers {
    print(number)
}

Output

Copied Numbers:
1
2
3
4
5

2 Copy String Set

In this example,

We create a set named fruits containing some string elements.
We assign fruits to a new variable named copiedFruits.
Now, copiedFruits contains a copy of all elements from fruits.

Swift Program

let fruits: Set<String> = ["Apple", "Banana", "Cherry", "Date"]
let copiedFruits = fruits

print("Copied Fruits:")
for fruit in copiedFruits {
    print(fruit)
}

Output

Copied Fruits:
