The benefit of a style rule must be large enough to justify asking engineers to In those cases it is appropriate to constrain or ban languageįeatures or idioms. However, sometimes language featuresĪnd idioms are flawed, or were just designed with assumptions that are not Reasons as consistency within our code base. Be consistent with Apple SDKsĬonsistency with the way Apple SDKs use Objective-C has value for the same Points is outweighed by the cost of having people argue over them. Stop worrying about it” the potential value of allowing flexibility on these Rules that are attributed to “Be Consistent” boil down to “Just pick one and Consistency alsoĮnables better automation because consistent code allows more efficientĭevelopment and operation of tools that format or refactor code. Using one style consistently throughout aĬodebase lets engineers focus on other (more important) issues.
