The Composable Architecture (TCA) is gaining traction among iOS developers due to its organized structure, clear components, and robust documentation. However, the article highlights the critical importance of managing state and actions, especially as app complexity increases. An experiment revealed that performance deteriorates significantly with deep nesting of states, illustrating a 50x increase in resource usage when actions are triggered at greater depths. This emphasizes the need for intentional structuring of app states or possibly adopting a feature-specific state management approach to better handle performance as apps evolve.
The performance results demonstrate that complexity almost doubles with each additional level of nested state; by level 10, you're spending roughly 50x more resources processing actions.
Using a single app state can be powerful, but it requires strict management of actions and depth of nested state to maintain performance.
The debate among developers shows that while TCA has its strengths, like clear components and solid documentation, there are also opinions about it being overengineered.
In real apps triggering many actions repeatedly is unlikely, but the experiment highlights the importance of structuring actions and state thoughtfully.
