Creating UI framework adapters

When integrating user interface frameworks, Clean Architecture’s separation of concerns becomes particularly valuable. UI frameworks tend to be both volatile and opinionated, making it crucial to isolate their influence from our core business logic. In this section, we’ll explore how to implement framework adapters that maintain clean boundaries while delivering practical user interfaces.
