Arrays in Swift in Swift

Lesson

The entries of Arrays are mutable and can be changed freely, using indices and subscript notation:

Subscript notation takes two operands which represent an index and a value and changes the element placed at that index with the argument value:

var numbers = [50, 40, 30]

numbers[0] = 15
numbers[2] = -1

// numbers is now [15, 40, -1]

Assignment
