iOS Swift Collections and Control Flow Introduction to Collections Working With Arrays

method remove(at:) iOS

is this right

array.swift
// Enter your code below

var arrayOfInts =  [1,2,3,4,5,6]
arrayOfInts.append (7)
arrayOfInts += [8]
let value = arrayOfInts [4]
 discardedValue.remove (at: 5)

For the last task, remove the 6th item from the array and assign the result to a constant named discardedValue.

To remove an item, use the method remove(at:) and put the index number in between parentheses that you want to remove.

Hey Robert!

There's a "let" missing in the last line of code. Don't forget that hehe :P

Happy coding

My bad, shouldn't also be something like this??

let discardedValue = arrayOfInts.remove(at: 5)

Sorry I didn't pay the proper attention to the whole line!
