How to find the length of a string in Swift

Theodore Kelechukwu Onyejiaku

Overview

The number of characters that make up a string is the length of that string. We can find this in Swift through the count property. It returns this number.

Syntax

string.count

Return value

The value returned is an integer. It is the number of characters a string has.

Code example

// create strings
let str1 = "Edpresso"
let str2 = "is"
let str3 = "awesome!"
let str4 = ""

// check length of strings
// and print result
print(str1.count)  // 8
print(str2.count)  // 2
print(str3.count)  // 8
print(str4.count)  // 0
Get the length of strings in Ruby

  • Lines 9-12: We check the length of the strings using the count property and print the results.
