Swift Array remove()

In this tutorial, we will learn about the Swift array remove() method with the help of examples.

The remove() method removes an element from the array at the specified index.

Example

// create an array
var prime = [2, 3, 5, 7, 9, 11]

// remove 9 from the array prime.remove(at:4)
// print updated prime array print(prime) // Output: [2,3,5,7,11]

remove() Syntax

The syntax of the array remove() method is:

array.remove(at: index)

Here, array is an object of the Array class.


remove() Parameters

The remove() method takes only one parameter:

  • index - index of the element to remove

remove() Return Value

  • returns the element that was removed from array

Example: Swift Array remove()

// languages array
var languages = ["Swift", "C", "Objective-C"]

print("Before Removing:", languages)

// "Objective-C" (at index 2) is removed var removed = languages.remove(at: 2)
print("After Removing:", languages) print("Removed Element:", removed)

Output

Before Removing: ["Swift", "C", "Objective-C"]
After Removing: ["Swift", "C"]
Removed Element: Objective-C

Here, we have removed "Objective-C" from the languages array. The removed element is stored in the removed variable.
