How to Get Array Length in Swift - Step by Step Examples

How to Get Array Length in Swift ?

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

In this example,

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

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

Length of array is: 5

In this example,

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

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

Length of array is: 5
