title: CocoaPods not linking libraries
body: <p>i recently started using CocoaPods to manage dependencies in my existing ios project.  i am using Xcode 7.1.1 on a Mac running OS X 10.11.1 (El Capitan). </p>
  
  <p>the problem is that i seem to still have to explicitly link the frameworks in the Link Binary with Libraries section of the Build phases, or i get error messages to the effect that "_OBJC_CLASS_$_Crashlytics", referenced from: ld: symbol(s) not found for architecture x86_64 ... i get a number of these errors for classes defined in the CocoaPods-managed dependencies.  if i explicitly add the relevant frameworks in the Pods project in the Link Binary with Libraries section of my target, everything works, but from my understanding, this should not be necessary.</p>
  
  <p>here's the podfile:</p>
  
  <pre><code># Uncomment this line to define a global platform for your project
   platform :ios, '7.0'
  # Uncomment this line if you're using Swift
  # use_frameworks!
  
  workspace 'myproject'
  
  def shared_pods
    pod 'ParseUI'
    pod 'ParseCrashReporting'
    pod 'Fabric'
    pod 'Crashlytics'
  end
  
  target 'myproject' do
    shared_pods
  end
  
  target 'myprojectTests' do
    shared_pods
    pod 'OHHTTPStubs'
  end
  </code></pre>
  
  <p>i'm guessing this has something to do with the fact that i added pod mgmt to an existing project.  i've tried different Podfile configurations, i've tried deleting and reinstalling, and nothing has worked so far...the only reliable solution to prevent the errors is to explicitly link the relevant frameworks that are in the Pods directories.</p>
  
  <p>any help much appreciated</p>
