ProgramGuruTo initialize a set in Swift, you can use the Set data structure with various initialization methods.
In this example,
mySet.mySet with an array literal containing initial elements using the Set type initializer Set(arrayLiteral:).mySet using set operations such as adding elements, removing elements, and checking for membership.var mySet: Set<String> = Set(arrayLiteral: "apple", "banana", "orange")
// mySet is now initialized with elements "apple", "banana", and "orange"
// Example usage:
// Add elements to the set
mySet.insert("kiwi")
// Remove elements from the set
mySet.remove("banana")
// Check if an element is present in the set
let containsElement = mySet.contains("apple")
print("Is element 'apple' present in the set: \(containsElement)")Is element 'apple' present in the set: true
In this example,
emptySet.emptySet using the default constructor Set().emptySet using set operations such as adding elements, removing elements, and checking for membership.var emptySet: Set<String> = Set()
// emptySet is now initialized as an empty set
// Example usage:
// Add elements to the set
emptySet.insert("apple")
// Remove elements from the set (if it exists)
emptySet.remove("apple")
// Check if an element is present in the set
let containsElement = emptySet.contains("apple")
print("Is element 'apple' present in the set: \(containsElement)")Is element 'apple' present in the set: false
