I agree. I am wondering if we should separate the two topics into distinct threads though. As this topic has most recently been focused on classes perhaps we should adjust the subject line and start a new thread focused on methods within classes that are not final. > On Mon, Dec 21, 2015 at 9:19 AM Tomáš Linhart <[email protected] > <mailto:[email protected]>> wrote: > Hello, > > I must say, I am not big fun of this proposal because currently in Swift only > way how to mock classes is to subclass them.
