title: Swift Entry Point
body: <p>I am very new to Swift, Just one line:</p>
  
  <blockquote>
    <p>Code written at global scope is used as the entry point for the program, so you don’t need a main() function. You also don’t need to write semicolons at the end of every statement.</p>

  <p>I have gone through <a href="https://stackoverflow.com/questions/24105690/what-is-the-entry-point-of-swift-code-execution">What is the entry point of swift code execution?</a></p>
  
  <p>I really don't understand how main.m is merged with AppDelegate.swift, Can somebody explain it in a simple way. Thanks!</p>
