How to check if an Array is Empty in Swift - Step by Step Examples

How to check if an Array is Empty in Swift ?

To check if an array is empty in Swift, you can use the isEmpty property.

In this example,

We create an array named numbers with some elements.
We check if the array is empty using the isEmpty property and store the result in the variable isEmpty.
Finally, we print whether the array is empty or not.

let numbers = [1, 2, 3]
let isEmpty = numbers.isEmpty
print("Array is empty: \(isEmpty)")

Array is empty: false

In this example,

We create an empty array named emptyArray.
We check if the array is empty using the isEmpty property and store the result in the variable isEmpty.
Finally, we print whether the array is empty or not.

let emptyArray: [Int] = []
let isEmpty = emptyArray.isEmpty
print("Array is empty: \(isEmpty)")

Array is empty: true
