How to create a Set of Strings in Swift ?

Answer

To create a set of strings in Swift, you can use the Set data structure.

✐ Examples

1 Create a Set of Strings using Set

In this example,

We define a Set object named stringSet to store strings.
We use the insert() method to add strings to the set.

Swift Program

var stringSet = Set<String>()
stringSet.insert("Apple")
stringSet.insert("Banana")
stringSet.insert("Orange")
stringSet.insert("Grapes")
print("Set of strings: (stringSet)")

Output

Set of strings: ["Orange", "Apple", "Banana", "Grapes"]

2 Create a Set of Strings using Array Literal

In this example,

We directly initialize the Set with an array literal containing strings.

Swift Program

var stringSet: Set<String> = ["Apple", "Banana", "Orange", "Grapes"]
print("Set of strings: (stringSet)")

Output

Set of strings: ["Orange", "Apple", "Banana", "Grapes"]
