title: Cocoapods Test Issue - Duplicate "one of the two will be used. which one is undefined."
body: <p>I've been trying to solve this issue for a couple days and haven't found a solution. Whenever I try to run a test I receive the error shown below that there are duplicate classes.</p>
  
  <p>I tried these answers but I'm still receiving the duplicate error and my tests won't run</p>

  <p>My pod file looks like this:</p>
  
  <pre><code>platform :ios, "8.0"
  
  def project_pods
  pod "Braintree"
  pod "AFNetworking", "~&gt; 3.0"
  pod "MBProgressHUD"
  pod "ActionSheetPicker-3.0", "~&gt; 2.0.1"
  pod "SCLAlertView-Objective-C", "~&gt; 0.7"
  pod "GoogleMaps"
  pod "MPSHorizontalMenu"
  pod "Fabric"
  pod "Crashlytics"
  pod "RateView"
  pod "QBImagePickerController"
  pod "GLCalendarView", "~&gt; 1.0.0"
  pod "Heap"
  pod "AWSS3"
  end
  
  target “iOS_project” do
      project_pods
  end
  
  target “iOS_projectTests” do
  project_pods
  end
  </code></pre>
  
  <p>This is what the error looks like and it is for every cocoapod class:</p>
  
  <p>Class GMSAutocompleteResultsViewController is implemented in both /Users/john/Library/Developer/CoreSimulator/Devices/27CF0470-07AC-4575-8907-A27EE9B357A7/data/Containers/Bundle/Application/7AFB0886-9ED1-464D-8B02-067CDD07511D/iOS_project.app/iOS_project and /Users/john/Library/Developer/Xcode/DerivedData/iOS_projectTests-hezbkjqviaiitthcrrnwetvcojcb/Build/Products/Debug-iphonesimulator/iOS_projectTests.xctest/iOS_projectTests. One of the two will be used. Which one is undefined.</p>
  
  <p>All of the pods are Objective C and I am using a bridging header</p>
