How to Declare an Array in Swift - Step by Step Examples

How to Declare an Array in Swift ?

In Swift, you declare an array using square brackets and optionally specify the type.

In this example,

We declare an array named numbers of type [Int] and initialize it with some values.
This creates an array of integers in Swift.
We print the array elements to the console.

let numbers: [Int] = [1, 2, 3, 4, 5]
print("Array elements:", numbers)

Array elements: [1, 2, 3, 4, 5]

In this example,

We declare an array named values of type [Double] and initialize it with some values.
This creates an array of double-precision floating-point numbers.
We print the array elements to the console.

let values: [Double] = [1.1, 2.2, 3.3, 4.4, 5.5]
print("Array elements:", values)

Array elements: [1.1, 2.2, 3.3, 4.4, 5.5]

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