@doug There are some really good questions here Doug! I've added a post here to help those new to design. It includes a few templates for exploring users before going into the prototyping process. Next I'll cover bringing prototyping into the process, and suggest which tools can be most useful depending on the stage you're at. I'm not too experienced with Xcode, but I have some friends in mind that I know are more knowledgable on this. I'll send them an invite!
