- rule added i.e. redundant_extension #5359 #5397

To be honest, I don't deem this rule to be as useful as I intentionally thought. The OSS report contains a lot of false positives. It's pretty common to conform a foreign type to a local protocol. And quite often the type already comes with the requirements defined in the protocol causing an empty body. So blindly triggering on every extension with an empty body isn't the way to go in my opinion. What might be acceptable is that the rule only triggers on empty extension if the extended type is defined in the same file. In that case, the conformance can just be moved to the type's definition. This could be a convention that projects follow, and the rule could support them with it. That said, I think this rule requires some more thought and, admittedly, the implementation for what I suggest above is a bit more involved. |
