Universal links on iOS vs. deep links (URL schemes)
<p>As I'm reading, iOS 9 introduced Universal Links. In the "Support Universal Links" section in Apple's <a href="https://developer.apple.com/library/ios/documentation/General/Conceptual/AppSearch/UniversalLinks.html" rel="noreferrer">App Search Programming Guide</a>, it says that this is not exactly like deep linking with URL schemes, but I'm not totally clear about this topic:</p>

<ul>
<li>What is actually the difference(s) between Universal Link and the URL Schemes? Is it that a Universal Link is only for hyperlinks in websites, and the Mail or Messages apps?</li>
<li>Do Universal Links replace URL schemes?</li>
<li>Are Universal Links a type of deep link?</li>
</ul>
