title: Target overrides the `OTHER_SWIFT_FLAGS` build setting
body: <p>Here is my pod file: </p>
  
  <pre><code>platform :ios, '8.0'
  use_frameworks!
  
  target 'TestApp' do
    ...
  end
  </code></pre>
  
  <p>After <code>pod install</code>I get the following errors:</p>
  
  <pre><code>[!] The `TestApp [Debug]` target overrides the `OTHER_SWIFT_FLAGS` build setting defined in `Pods/Target Support Files/Pods-TestApp/Pods-TestApp.debug.xcconfig'. This can lead to problems with the CocoaPods installation
      - Use the `$(inherited)` flag, or
      - Remove the build settings from the target.
  
  [!] The `TestApp [Release]` target overrides the `OTHER_SWIFT_FLAGS` build setting defined in `Pods/Target Support Files/Pods-TestApp/Pods-TestApp.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><strong>How do I resolve this problem?</strong></p>
