How to Get Array Length in Swift


How to Get Array Length in Swift ?

Answer

To get the length of an array in Swift, you can use the count property of the array.



✐ Examples

1 Length of Integer Array

In this example,

  1. We create an integer array named numbers with some values.
  2. We then get the length of the array using count property of the array object numbers, and store the returned value in length variable.
  3. Array.count property returns the length of this array.
  4. Finally, we shall print the value in length to standard output.

Swift Program

let numbers = [1, 2, 3, 4, 5]
let length = numbers.count
print("Length of array is: \(length)")

Output

Length of array is: 5

2 Length of String Array

In this example,

  1. We create a string array named names with some values.
  2. We then get the length of the array using count property of the array object names, and store the returned value in length variable.
  3. Array.count property returns the length of this array.
  4. Finally, we shall print the value in length to standard output.

Swift Program

let names = ["Alice", "Bob", "Charlie", "David", "Eve"]
let length = names.count
print("Length of array is: \(length)")

Output

Length of array is: 5

Summary

In this tutorial, we learned How to Get Array Length in Swift language with well detailed examples.
