Swift String remove()

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

The remove() method removes a character in the string at the specified position.

var i = greet.index(greet.startIndex, offsetBy: 4)


// remove the character
greet.remove(at: i)


print(greet)

// Output: Goodmorning

remove() Syntax

The syntax of the string remove() method is:

string.remove(at: i)

Here, string is an object of the String class.

remove() Parameters

The remove() method takes only one parameter.

  • i - index of the character to remove

Example: Swift string remove() 

var message = "Hello, World!"

print("Before Removing:", message)

// position of the character to remove
var i = message.index(message.startIndex, offsetBy: 12)


// remove the character at index i
var removed = message.remove(at: i)


print("After Removing:", message)
