title: What is Pods-App.framework and it is a umbrella framework?
body: <p>I have a question about whether Pod-App.framework in <code>/Build/Product</code> directory, is it an umbrella framework?</p>
  
  <p>I just found Pods_App.the framework has a header <code>Pods-App-umbrella.h</code> and searched around did not get more info.</p>
  
  <p>As I know Umbrella framework may have a sub-framework in the directory.</p>
