The removeFirst() method removes the first element from the set.
Example

// removes and returns first element from brands
print(brands.removeFirst())
// Output: Apple
removeFirst() Syntax
The syntax of the set removeFirst() method is:
set.removeFirst()
Here, set is an object of the Set class.
removeFirst() Parameter
The removeFirst() method doesn't take any parameter.
removeFirst() Return Value
The removeFirst() returns the removed element from the set
Note: Since Sets are unordered collections, the random element is removed and returned.
Example: Swift Set removeFirst()
var country: Set = ["Nepal", "Greece", "Spain"]
// removes and returns first element from country
print(country.removeFirst())
// print the modified set
print(country)
Output
Spain ["Greece", "Nepal"]
Here, we have used the removeFirst() method to remove the first element from the country set.
After removing the first element, we have printed the modified set.
