.removeAll()

The .removeAll() method is used to remove every value from a Set in Swift.

setName.removeAll()

• .removeAll() will remove all values from setName.
• It is not possible to use a (where:) condition on a set because Set does not currently conform to the RangeReplaceableCollection protocol that includes that method.

The following is an example of the .removeAll() method:

var weather: Set = ["spring", "summer", "autumn", "fall", "winter"]

weather.removeAll()

print(weather)

This will output:

[]
