Discussion 解説
In the following example, the non set is made up of the elements of the employees set that are not elements of neighbors:
次の例において、non集合はemployees集合の要素でneighborsの要素でないものから作り上げられます：
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"]"
