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

How to Declare an Integer Array in Swift ?

Answer

To declare an integer array in Swift, you can use array literals or the Array constructor.


✐ Examples

1 Declare and Initialize an Integer Array

In this example,

  1. We declare an integer array named numbers with predefined values using array literals.
  2. We print the array to demonstrate the initialization.

Swift Program

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

Output

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

2 Declare an Empty Integer Array

In this example,

  1. We declare an empty integer array named emptyArray using the Array constructor.
  2. We print the array to demonstrate the declaration.

Swift Program

let emptyArray = [Int]()
print("Empty Integer Array:", emptyArray)

Output

Empty Integer Array: []

Summary

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