var values:[Int] =  print( "size of values is : \(values.count)" ) var numbers:[Int] = [7, 54, 21] print( "size of numbers is : \(numbers.count)" )
size of values is : 0 size of numbers is : 3
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.
