UIScrollView scroll enabling
<p>I'm currently working on a Swift app that requires a few UIScrollViews, however I'm running into some problems making it work for all device sizes.</p>

<p>In this situation, I would have a content that would all appear on an iPhone 6, but not necessarily on an iPhone 4 or 5.</p>

<p>I've got a scroll view set up with some content and I would like to make it scrollable only if you don't see the full content.</p>

<p>Is there a way to perhaps detect if a certain element is visible?</p>
