How to check if an Array is Not Empty in Swift - Step by Step Examples
How to check if an Array is Not Empty in Swift ?
Answer
In Swift, you can use the isEmpty
property of an array to check if it's not empty.
✐ Examples
1 Check if Given Array with Elements is 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 variablenotEmpty
. - Finally, we print whether the array is not empty or not.
Swift Program
let numbers = [1, 2, 3]
let notEmpty = !numbers.isEmpty
print("Array is not empty: \(notEmpty)")
Output
Array is not empty: true
2 Check if Empty Array is Not Empty
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 variablenotEmpty
. - Finally, we print whether the array is not empty or not.
Swift Program
let emptyArray: [Int] = []
let notEmpty = !emptyArray.isEmpty
print("Array is not empty: \(notEmpty)")
Output
Array is not empty: false
