title: how to use objective-c category cocoapods in swift project
body: <p>I know how to use objective-c project as a pod in swift project. But I don't know how to use an objective-c category. I can D&amp;D to use the category project, however I want to use it in cocoapod way for ease of updates. </p>
  
  <p>my iOS-Bridging-Header.h</p>
  
  <pre><code>#import &lt;FIR/FIR.h&gt;
  #import &lt;NSDate-Escort/NSDate+Escort.h&gt;
  </code></pre>
  
  <p>When I import the second file, the Xcode says: </p>
  
  <pre><code>'NSDate-Escort/NSDate-Escort.h' file not found
  </code></pre>
  
  <p>my Podfile</p>
  
  <pre><code>platform :ios, '8.0'
  use_frameworks!
  
  target 'TimeMachine' do
    pod 'FIR.im', '~&gt; 1.3.1'
    pod 'MGSwipeTableCell', '~&gt; 1.5.1'
    pod 'XCGLogger', '~&gt; 2.3'
    pod 'NSDate-Escort', '~&gt;1.5.1'
  end
  
  target 'TimeMachineTests' do
  
  end
  </code></pre>
  
  <p>I executed pod install, and the pods are installed correctly..</p>
