If the asset catalog or the built-in dynamic colors are not flexible enough a view can do appearance sensitive work in the following methods: “updateConstraints", "layout", "draw:dirtyRect" and "updateLayer”. The current appearance can be queried using “effectiveAppearance” and “bestMatch” can be used on the returned appearance.</div><div class=""><br class=""></div><div class="">But if you can upgrade Xcode to a later version it would be much simpler.</div><div class=""><br class=""></div><div class="">[1] <a href="https://developer.apple.com/videos/play/wwdc2018/218/" class="">https://developer.apple.com/videos/play/wwdc2018/218/</a></div><br class=""><div class="">-- <br class="">/Jacob Carlborg</div></body></html>
