title: - Use the `$(inherited)` flag, or - Remove the build settings from the target. CocoaPod Swift3 pod update error
body: <p>I've been running into a couple of strange errors in terminal when updating cocoapods after updating a Switf2 project to Swift3. Here are the errors:</p>
  
  <pre><code>[!] The `MyShowGuide [Debug]` target overrides the `FRAMEWORK_SEARCH_PATHS` build setting defined in `Pods/Target Support Files/Pods-MyShowGuide/Pods-MyShowGuide.debug.xcconfig'. This can lead to problems with the CocoaPods installation
      - Use the `$(inherited)` flag, or
      - Remove the build settings from the target.
  
  [!] The `MyShowGuide [Release]` target overrides the `FRAMEWORK_SEARCH_PATHS` build setting defined in `Pods/Target Support Files/Pods-MyShowGuide/Pods-MyShowGuide.release.xcconfig'. This can lead to problems with the CocoaPods installation
      - Use the `$(inherited)` flag, or
      - Remove the build settings from the target.
  </code></pre>
  
  <p>So far I've tried numerous ways to try and remedy the issue including deleting derived data and running <code>pod deintegrate/ pod install</code>.  I also added <code>$(inherited)</code> to the  <code>Other Linker Flags</code> and <code>Header Search Paths</code> but still get the error.</p>
