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"
