title: WorkSpace Vs Project Vs Target in Xcode
body: <p>As I am new to Xcode, I do not understand clearly how Xcode organizes workspaces and projects. By using Google, I believe the following:</p>
  
  <ol>
  <li>A workspace contains many projects.</li>
  <li>Project contains many Targets</li>
  <li>A project should have at least one target.</li>
  </ol>
  
  <p>Are all of the above statements are true?</p>
  
  <ol start="4">
  <li><p>If i have one class called (login.h,login.m,login.xib) in my project, can I use the same login file in different targets?</p></li>
  <li><p>Can i use the same file in different Projects.</p></li>
  </ol>
  
  <p>If there is a tutorial or other articles that explain, please let me know of them.</p>
