Thanks, its a good point. I've only played with swift, but I've written a fair amount of objective C, and I didn't put 80 cols in coding standards for my company for that. We got away with that because the environment was fixed. And the path of least resistance was to use it in the way Apple told you to. You couldn't even split XCode more than two ways back then (iirc). So the issue of different tools, different screen layouts, and different workflows didn't raise. So yeah, 80cols isn't a panacea across all languages.
