Join Bill Weinman for an in-depth discussion in this video Exercise files, part of iOS SDK and SQLite: Building Data-Driven Apps (2013).
The exercise files for this course are included with your basic lynda.com membership. If you are a lynda.com member you have access to the exercise files used throughout this title. Copy the exercise files to a location where you can find them on your system. Make sure it's a location that doesn't have any spaces in the file path. Some of Xcode's tools do not work properly if there are spaces in file names. I have copied them to the desktop on this system. The exercise files are laid out by Chapter with each folder corresponding to a Chapter in the course.
Within the Chapter folder there are other folders with Xcode projects in them. An Xcode project will have one or more folders inside of it and a file with the name of the project followed by .xcodeproj. You open this project in Xcode by double-clicking on the Xcode project file. I recommend that you make a working copy of one of these projects before you open it in Xcode. You can easily do that on a Mac by holding down the Option key and dragging the folder into an empty space in the containing folder.
When you let go of the mouse button, Finder will make a copy of that entire folder tree and rename it with a number after it. Then you simply click on it, maybe click on it again, and Finder will allow you to rename it. And then you can open that project in Xcode by double-clicking on the Xcode Project file. Some of the Chapters have files in them that end in .txt, these are text files that contain Objective-C code.
You want to open these in a plain text editor like TextWrangler or BBEdit or another plain text editor that is not a Word Processor. Word Processors add other information, other invisible information to your code and make it unusable in Xcode. The code in these files will be copied and pasted in the Xcode so that you don't have to type a lot of code yourself. The exercise files are here to make you a learning experience easier and more powerful. Be sure to take the time to read the code and experiment with it, make changes, make mistakes.
There is a lot of code here, take the time to learn with it.
