Yeah, if it did strict checking, then I'd have to paramaterize every single occurrence of 'NSArray' and 'NSDictionary' in my entire 40,000-LOC project, which would take quite a while. [Although I guess the checking could be enabled by a compiler flag on a file-by-file basis.]
I wonder if this is something that could be done by a refactoring tool? (I was v. impressed at how the Swift2 converter can actually rewrite code that used manual error checking to use exceptions!)
