To access items in a set in Swift, you can use iteration or specific methods provided by the Set class.
In this example,
stringSet
containing strings.var stringSet: Set<String> = ["Apple", "Banana", "Orange", "Grapes"]
for item in stringSet {
print(item)
}
Apple Banana Orange Grapes
In this example,
numberSet
containing integers.contains
method to check if an item exists in the set.count
property to get the number of elements in the set.var numberSet: Set<Int> = [1, 2, 3, 4]
print("Number of elements: \(numberSet.count)")
print("Does set contain 3? \(numberSet.contains(3))")
Number of elements: 4 Does set contain 3? true
