To add a new element to a set in Swift, you have to use the insert
method of the Set
data type. The insert
method takes as input the element that you want to add to the set.
Here's an example of how you can add an element to a set in Swift:
main.swift140 chars8 lines
In this example, we create an empty set of type String
. We then use the insert
method to add a new element "element1"
to the set. Finally, we print the contents of the set to verify the element was added successfully.
Alternatively, you could also use the insert
method with shorthand notation:
main.swift169 chars8 lines
In this example, we create a set with two initial elements "element1"
and "element2"
. We then use the insert
method with shorthand notation to add a new element "element3"
to the set. Finally, we print the contents of the set to verify the element was added successfully.
