how to get the difference of two sets in swift

To obtain the difference of two sets in Swift, you can use the subtracting method which returns a new set with the elements that are in the first set but not in the second set.

Here's an example:

main.swift
let setA: Set = [1, 2, 3, 4, 5]
let setB: Set = [4, 5, 6, 7, 8]

let diff = setA.subtracting(setB)

print(diff) // Output: [1, 2, 3]
133 chars
7 lines

In this code snippet, setA and setB are two sets with some shared elements.

By calling the subtracting method on setA with setB as an argument, we obtain a new set with the elements that are in setA but not in setB.

In this case, the difference set will contain the elements [1, 2, 3].
