(There is a trend with Swift to make everything more safe and enterprisey, as in JVM languages, though.)&lt;p&gt;But this isn&amp;#x27;t about calling private methods, it&amp;#x27;s about navigating the view hierarchy, which is possible in every GUI framework I&amp;#x27;ve used so far.</text><parent_chain><item><author>soperj</author><text>That sounds really screwed up.
