I am currently using the Xcode 10 edition of the "Intro to App Development for Swift." In section 5.1 p 27 (we are asked to create a new project and set it up as they have on that page). In my Xcode project there is no devices tab to choose iphone from. I am not quite sure why this is this way but I tried to continue on with the project and I ran into other errors such as, no "Main.storyboard" to choose from in the navigator. I am wondering if the book I am using is not the correct edition but I ran to similar issues when I was using an older edition as well. Any insight, (if you can decipher this question) is appreciated. This is frustrating as a novice. Thank you in advance for your help.
