Liz’s oF Tips
//What you would have wished you had known.
If xCode tells you it needs to update your project’s anythings (references, settings, whatever) DON’T. You will burst into tears in the middle of the lab when literally everything you’ve ever created breaks.
If you keep having to reset the Base SDK, do it in the emptyExample that you keep copying over and you’ll NEVER have to do it again!!!!
