How to Convert a Set of Integers to a Set of Strings in Swift - Step by Step Examples

How to Convert a Set of Integers to a Set of Strings in Swift ?

To convert a set of integers to a set of strings in Swift, you can use the `map` function to transform each integer into its string representation.

In this example,

We have a set of integers named intSet.
We use the map function to transform each integer in intSet into its string representation.
The map function applies the given closure to each element of the set and returns a new set containing the resulting values.

let intSet: Set<Int> = [1, 2, 3, 4, 5]
let stringSet = intSet.map { String($0) }

print(stringSet)

["1", "2", "3", "4", "5"]

In this example,

We have an empty set of integers named emptySet.
We use the map function to transform each integer in emptySet into its string representation.
Since there are no elements in emptySet, the resulting set of strings will also be empty.

let emptySet: Set<Int> = []
let stringSet = emptySet.map { String($0) }

print(stringSet)

[]
