What is debugDescription property of a String in Swift?

Overview

We can use the debugDescription property on a string instance to return the representation of the string suitable for debugging.

Syntax

string.debugDescription

Return value

This property returns the representation of the string suitable for debugging.

Example

Let’s look at the code below:

// create some strings
let name = "Theodore"
let language = "Swift"
let emptyString = ""
// get debugDescription property
let debugDesc1 = name.debugDescription
let debugDesc2 = language.debugDescription
let debugDesc3 = emptyString.debugDescription
// print results
print(debugDesc1) // "Theodore"
print(debugDesc2) // "Swift"
print(debugDesc3) // ""
