+1 to the proposal
+1 to teach how to remove live issues to beginners, so they have a chance to train at detecting errors without the compiler

>>> One of the biggest issues that I saw while teaching Swift to newbies (most had not programmed before) is confusion based on the early warnings/errors that swift/xcode gives you as they type. What would happen is that they would type a variable, and it would say… “You haven’t used this variable” and so they would just click the fixit because they trust the compiler more than they trust themselves. This would lead to a point where they were very confused because some of the code was code they had thought through, and some of it was changed by random fixits in ways they didn’t understand… and so it would lead to more errors/fixits until they had errors which couldn’t be fixed.
