What is the localizedUppercase property of a String in Swift?

Overview

The localizedUppercase property of a String instance in Swift is used to get the uppercase version of a string that is produced using the current locale.

Syntax

string.localizedUppercase

Return value

This property returns the uppercase representation of the String instance string.

Example

Let’s look at the code below:

// import the foundation framework
import Foundation
// create strings 
let str1 = "Metamask"
let str2 = "Solana"
let str3 = "NFT"
let str4 = "BlockCHAIN"
let str5 = "Meta"
// get the capitalized representation
print(str1.localizedUppercase)
print(str2.localizedUppercase)
print(str3.localizedUppercase)
print(str4.localizedUppercase)
print(str5.localizedUppercase)

Explanation

  • Line 2: We import the Foundation framework, which provides methods and functionalities such as the localizedUppercase property.
  • Lines 5 to 9: We create some strings.
  • Lines 12 to 16: We get the uppercase representations of the strings we created using the localizedUppercase property and print the returned values to the console.
