In addition, writing code that is accessible to juniors (which should apply to a large majority of a code base) increases the velocity of everyone on the team. Readability, modularity, and consistency create standards and examples for a junior to work by, which is a great way to learn and lower the risk of bugs and surprises.
Yup. This is why I favour simple architectures like MVC over complex ones like VIPER.
While there may be exceptions, I default to: if an app is so messy as to consider a more complex architecture, it probably has so much going on as to be difficult for the end user to use it.
