In Swift, you can convert a set of strings to a set of integers using the `map` function along with the `Int` initializer.
In this example,
let stringSet: Set<String> = ["1", "2", "3", "4", "5"]
let intSet = Set(stringSet.map { Int($0) ?? 0 })
print(intSet)
[5, 2, 3, 4, 1]
In this example,
let stringSet: Set<String> = ["1", "2", "3", "four", "5"]
let intSet = Set(stringSet.map { Int($0) ?? 0 })
print(intSet)
[5, 2, 3, 0, 1]
