Submitted by Nidhi, on June 16, 2021

Problem Solution:

Here, we will create two arrays of integers. Then we will check an array is empty or not using the isEmpty() function.

Program/Source Code:

The source code to check an array is empty or not is given below. The given program is compiled and executed successfully.

// Swift program to check an array is empty or not

import Swift

var arr1:[Int] = [12,10,25,20,50]
var arr2 = [Int]()

if(arr1.isEmpty)
{
    print("Array arr1 is an empty array.")
}
else
{
    print("Array arr1 is not an empty array.")
}
if(arr2.isEmpty)
{
    print("Array arr2 is an empty array.")
}
else
{
    print("Array arr2 is not an empty array.")
}

Output:

Array arr1 is not an empty array.
Array arr2 is an empty array.

...Program finished with exit code 0
Press ENTER to exit console.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift;

Here, we created two integer arrays arr1 and arr2. Then we used the isEmpty() function to check an array is empty or not, and printed appropriate messages on the console screen.
