title: How to add items to an Outlet Collection in Xcode
body: <p>I am creating a quiz app and for the buttons I need an outlet collection. So far in the array, I only have one button but I want to add the other three. On the other tutorial I've watched, it says to click the button on the side and drag to the thing you want to add (image link below). This doesn't work for me, is there a certain way you need to click? I've done this before, but this time its not working. The difference this time is that I've created a new class. I am not very familiar with Xcode or swift, sorry. Thank you.</p>
