Parameters

index: The position of the element to access. index must be greater than or equal to startIndex and less than endIndex.

The following example uses indexed subscripting to update an array’s second element. After assigning the new value ("Butler") at a specific position, that value is immediately available at that same position.

var streets = ["Adams", "Bryant", "Channing", "Douglas", "Evarts"]
streets[1] = "Butler"
print(streets[1])
// Prints "Butler"
