Returns a new set containing the elements of this set that do not occur
in the given set.
In the following example, the nonNeighbors set is made up of the
elements of the employees set that are not elements of neighbors:
let employees: Set = ["Alicia", "Bethany", "Chris", "Diana", "Eric"]
let neighbors: Set = ["Bethany", "Eric", "Forlani", "Greta"]
let nonNeighbors = employees.subtracting(neighbors)
print(nonNeighbors)
// Prints "["Diana", "Chris", "Alicia"]"
- Parameter other: A set of the same type as the current set.
- Returns: A new set.
