Understanding Xcode’s Project Templates
Although you can build an app from scratch by adding files to an empty project, it’s faster and more productive to flesh out a ready-made app skeleton.
Xcode includes a selection of app templates to get your projects started. The templates don’t do much, but they create a very basic app that you can expand by adding more features.
