How to Convert an Array of Strings to an Array of Integers in Swift ?

To convert an array of strings to an array of integers in Swift, you can use the `map` function along with `Int.init` to perform the conversion.

In this example,

We have an array of strings named strArray containing string representations of integers.
We use the map function to transform each element of strArray to an integer using Int.init.
The resulting array intArray contains the converted integers.
We print the contents of intArray to demonstrate the conversion.

let strArray = ["10", "20", "30"]
let intArray = strArray.map { Int($0) ?? 0 }
print("Converted array of integers:", intArray)

Converted array of integers: [10, 20, 30]

In this tutorial, we learned How to Convert an Array of Strings to an Array of Integers in Swift language with well detailed examples.
