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


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

Answer

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.



✐ Examples

1 Convert Strings to Integers

In this example,

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

Swift Program

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

Output

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

Summary
