How to convert the string to int in Swift

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

Converting string to int

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

In this example, we are converting the string "929" to an int 929:

let str = "929"
let convertedNumber = Int(str) ?? 0

print(convertedNumber)

Output:

929

In the above code, we have added the Int(str) ?? 0. it means the Int() returns an optional value 0; if it fails to convert the string into an int.
