How to Sort an Array in Swift


How to Sort an Array in Swift ?

Answer

To sort an array in Swift, you can use the built-in sorted() method.



✐ Examples

1 Sort Integer Array in Ascending Order

In this example,

  1. We create an integer array named numbers with values 5, 2, 8, 1, 6.
  2. We use the sorted() method on the array to sort it in ascending order.
  3. The sorted() method sorts the array elements in ascending order.
  4. Finally, we print the sorted array numbers to the console.

Swift Program

var numbers = [5, 2, 8, 1, 6]
let sortedNumbers = numbers.sorted()
print("Sorted array in ascending order: ", sortedNumbers)

Output

Sorted array in ascending order: [1, 2, 5, 6, 8]

2 Sort Integer Array in Descending Order

In this example,

  1. We create an integer array named numbers with values 5, 2, 8, 1, 6.
  2. We use the sorted() method on the array with a custom comparator to sort it in descending order.
  3. The custom comparator sorts the array elements in descending order.
  4. Finally, we print the sorted array numbers to the console.

Swift Program

var numbers = [5, 2, 8, 1, 6]
let sortedNumbers = numbers.sorted(by: { $0 > $1 })
print("Sorted array in descending order: ", sortedNumbers)

Output

Sorted array in descending order: [8, 6, 5, 2, 1]
