How to convert the Int to String in Swift

In this tutorial, we are going to learn about how to convert the int to a string in Swift.

Converting int to string

To convert an int to a string, we can use the built-in String() initializer syntax by passing the int value as an argument to it.

Here is an example, that converts the int 100 to an string "100":

let num = 100
let strNum = String(num)

print(strNum)

Output:

"100"

If it fails to convert it as a string, we can also return the optional value 0 like this.

let num = 100
let strNum = String(num) ?? 0

print(strNum)
