Just because it’s widely used doesn’t mean it’s a good idea. Remember, Swift is still very young. SOLID and other “old school" OOP principles are way older and proven to work at this point. For example, as an iOS contractor, I very, very often see extensions used for “code organization” of massive view controllers. It’s easy to do and looks pretty. But that’s just putting lipstick on a pig. Of course, this is just anecdotal evidence and a personal opinion. By no means I’m saying I’m right. Just sharing my view and voting. I may be wrong of course, especially among very smart people that are here.
