 <p>It sounds like you want to use something like <a href="https://github.com/onevcat/VVDocumenter-Xcode" rel="nofollow">VVDocumenter</a>. </p> <p>From their Github page:</p> <blockquote> <p>Writing document is so important for developing, but it is really painful with Xcode. Think about how much time you are wasting in pressing '*' or '/', and typing the parameters again and again. Now, you can find the method (or any code) you want to document to, and type in ///, the document will be generated for you and all params and return will be extracted into a Javadoc style, which is compatible with appledoc, Doxygen and HeaderDoc. You can just fill the inline placeholder tokens to finish your document.</p> </blockquote>
