In the development of the View Hierarchy feature for the Luciq SDK, the team aimed to enhance user interface (UI) debugging by letting developers inspect app views in 3D layers. Initially inspired by Xcode's View Hierarchy tool, the implementation faced challenges, such as calculating the visible frame of UIViews and managing performance issues related to capturing screenshots. The visible frame calculation required a recursive approach to capture intersections between superviews and subviews, which was complicated by factors like the clipsToBounds property and UIScrollView behavior. The performance challenge of freezing the UI during screenshot capture was addressed by using linked lists, enabling asynchronous execution on the main queue, allowing the UI to update and display an activity indicator between tasks. This iterative process overcame the initial limitations of static screenshots, ultimately providing developers with a more dynamic and informative debugging tool.
