How to check if an Array is Not Empty in Swift

How to check if an Array is Not Empty in Swift ?

In Swift, you can use the isEmpty property of an array to check if it's not empty.

In this example,

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

let numbers = [1, 2, 3]
let notEmpty = !numbers.isEmpty
print("Array is not empty: \(notEmpty)")

Array is not empty: true

In this example,

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

let emptyArray: [Int] = []
let notEmpty = !emptyArray.isEmpty
print("Array is not empty: \(notEmpty)")

Array is not empty: false
