True, if you're writing a typical app, it will probably be easiest for you if you write it in the same manner as most other people. But if you are doing something very new or unusual, a sample project like this can be invaluable, since it shows the exact set of system calls needed for an app and roughly the minimal code. This is useful if, for example, you're trying to make a new language framework run on iOS (like Swift, Kotlin, or Rust), or if you're trying to answer questions like, "How much of an app's size is unavoidable?"
