Swift Array dropFirst()

The dropFirst() method drops the first element and returns the remaining elements in the array.


var names = ["Dwight", "Kevin", "Creed"]

// drops first element // and returns remaining elements print(names.dropFirst())
// Output: ["Kevin", "Creed"]

dropFirst() Syntax

The syntax of the array dropFirst() method is:

array.dropFirst(i: Int)

Here, array is an object of the Array class.

dropFirst() Parameter

The dropFirst() method can take a single parameter:

  • i (optional) - number of elements to be dropped from the beginning of the array

dropFirst() Return Value

  • returns the remaining elements in the array after dropping the first element

Example 1: Swift Array dropFirst()

var country = ["Nepal", "Greece", "Spain"]

// drops first element and returns remaining elements print(country.dropFirst())
// original array is not modified print(country)


["Greece", "Spain"]
["Nepal", "Greece", "Spain"]

Here, we have used the dropFirst() method to drop the first element from the country array.

The original array is unchanged because dropFirst() creates a new array instead of modifying the original array.

Example 2: Drop Multiple Number of Elements

var languages = ["Swift", "Python", "Java", "C", "C++"]

print("Original Array:", languages)

// remove first two elements from languages print("After dropfirst():", languages.dropFirst(2))


Original Array: ["Swift", "Python", "Java", "C", "C++"]
After dropfirst(): ["Java", "C", "C++"]

Here, languages.dropFirst(2) removes the first 2 elements from languages and returns the remaining elements.
