on YouTube ↗20m

" summary

Shows how protocols with default implementations and conditional default implementations let code for showing and hiding a HUD be centralized across UIView and UIViewController subclasses how those layers compose into reusable mixins and how it actually works in an app including a real HUD that sometimes misses nav or tab bars and the fix of climbing to the enclosing controller explains the surprising dispatch bug where a protocol extension method is chosen over a concrete override and warns about overusing protocols versus subclassing with concrete lifecycle needs
