Swift 3 error: "See also" callout not showing
<p>I just migrated my project to Swift 3 and found that the &quot;See also&quot; callout in the quick help is not showing. Everything was perfectly working in the previous version of Swift. Below is my code:</p>
<pre><code>/**
 Adds a &quot;See also&quot; callout in the Quick Help for a symbol using the `seealso` delimiter. Multiple &quot;See also&quot; callouts appear in the description section in the same order as they do in the markup.

 - author: Tapas Pal

 - remark: Use the callout to add references to other information.

 - seealso: [The Swift Standard Library Reference](https://developer.apple.com/library/prerelease/ios//documentation/General/Reference/SwiftStandardLibraryReference/index.html)
*/
class SeeAlsoMarkup: NSObject {
    static func doSomething() {}
}
</code></pre>
<p>The output is as follows:</p>
<p><a href="https://i.stack.imgur.com/UiArX.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/UiArX.png" alt="enter image description here" /></a></p>
<p>Did Apple change anything with this markup? Apple's <a href="https://developer.apple.com/library/content/documentation/Xcode/Reference/xcode_markup_formatting_ref/SeeAlso.html" rel="nofollow noreferrer">See Also</a> markup formatting reference is still showing <code>seealso</code> as a valid callout.</p>
