</>
Copy
var values:[Int] = []
print( "size of values is : \(values.count)" )
var numbers:[Int] = [7, 54, 21]
print( "size of numbers is : \(numbers.count)" )
Output
size of values is : 0
size of numbers is : 3
Conclusion
In this Swift Tutorial, we have learned to get the size of the array or count the number of elements in the array using Swift example programs.
