Join Todd Perkins for an in-depth discussion in this video Using the exercise files, part of Learning iOS 10 App Development: 1 Create Your First App.
- [Instructor] The exercise files for this course are organized by chapters. Each chapter folder contains the appropriate files for that chapter. Chapter 01 is sort of the exception. In chapter one we create a project. I decided to save the finished version of my project that I created in that folder. Now as you're following along, you won't need to open up this file unless there's some sort of emergency. You're actually going to create this project on your own from scratch.
For the other chapters, I've included start and final states for each file, so every movie where we write some code or we build an application, I included the files in the start and final states for those movies, so you can navigate to the appropriate folder. In there, what you want is the start folder if you're following along, or the final folder if there's some discrepancy in the code that you've written and what you're seeing on the movie screen as you're watching the movie.
You can open up the final files and just check that against your own file and see maybe some code that you've missed. When you go to the start folder you're just gonna drill down and the file that you're looking for is the Xcode project file, .xcodeproj. If you just double-click that, the project is going to open up in Xcode. Now sometimes when the project opens up in Xcode, the user interface in Xcode might not exactly match what you see on my screen.
However, throughout the course, I'll show you how to layout Xcode to match what I'm seeing. For example, you can hide or show portions of the Xcode interface using buttons in the toolbar, like this right area we can show and hide using this button, and this left area we can show and hide using this button up here. We can split this middle interface in two by using this button. Again, throughout the course I'm going to explain that in detail.
I just wanted to point out right off the bat that if Xcode doesn't look exactly the same for you as it does for me on my screen in the movie that you're watching, that I will explain how I got my screen to that setting. Now if you don't have the exercise files, you don't need to worry at all. All the projects in this course are created from scratch, so we're just using assets that are built into Xcode, and we're going to be starting from scratch. Any small exceptions to that I will explain in the movie so that you can be up to speed throughout the whole course.
