   5 // Swift requires that main() be invoked from a file named "main.swift". See the
   6 // paragraph "Application Entry Points and “main.swift” on

   9 //      You’ll notice that earlier we said top-level code isn’t allowed in most
  10 //      of your app’s source files. The exception is a special file named
  11 //      “main.swift”, which behaves much like a playground file, but is built
  12 //      with your app’s source code. The “main.swift” file can contain top-level
  13 //      code, and the order-dependent rules apply as well. In effect, the first
  14 //      line of code to run in “main.swift” is implicitly defined as the main
  15 //      entrypoint for the program.  This allows the minimal Swift program to be
  16 //      a single line — as long as that line is in “main.swift”.
