body: <blockquote>
    <p>Here i have go through many link that similar to my question but I
    don't get satisfied answer. so here I have added my scenario.</p>
  </blockquote>
  
  <p>I have two separate iOS projects. lets give label to <code>First</code> and <code>Second</code>.
  now due to some scenario, I need <code>Second</code> project all features and views as well(example: Controllers, storyboard and business logic files) into <code>First</code> one. Both project are in larger size. Here I explore three different way.</p>
  
  <p>1: Drag and Drop <code>Second</code> project to <code>First</code> one.</p>
  
  <p>2: create static files of <code>Second</code> project.</p>
  
  <p>3: create framework of <code>Second</code> project.</p>
  
  <p>So kindly suggest me best efficient way to integrate <code>Second</code> project into <code>First</code> one so I can reduce source size to some extent and not need to manage <code>Second</code> project at two different places.</p>
  
  <p>Thanks</p>
