title: xcode workspace multi Project "no such module" for a pods
body: <p>Hi here's basically my Podfile configuration</p>
  
  <pre><code>platform :ios, '11.0'
  
  target 'Project1' do
    use_frameworks!
    workspace 'MyWorkspace'
    project 'Project1.xcodeproj'
  
    pod 'RxSwift', '~&gt; 4.0'
    pod 'Project2', :path =&gt; 'Project2'
    pod 'Project3', :path =&gt; 'Project3'
  
  
  end
  
  target 'Project2' do
    use_frameworks!
    workspace 'MyWorkspace'
    project 'Project2/Project2.xcodeproj'
  
    pod 'RxSwift', '~&gt; 4.0'
  
  end
  
  target 'Project3' do
    use_frameworks!
    workspace 'MyWorkspace'
    project 'Project3/Project3.xcodeproj'
  
      pod 'Alamofire'
      pod 'RxAlamofire'
      pod 'ObjectMapper', '~&gt; 3.0.0'
      pod 'AlamofireObjectMapper', '~&gt; 5.0'
  
  end
  </code></pre>
  
  <p>The problem is I have a <strong>"no such module RxSwift"</strong> from my Project2 files only when I build Project1 (which using Project2).</p>
  
  <p>Everything else is working, project are recognized as local pods etc.</p>
  
  <p>I tried to : </p>
  
  <ul>
  <li>update searPath of Project2 adding RxSwift adding "$PODS_CONFIGURATION_BUILD_DIR/RxSwift"</li>
  <li>adding RxSwift.framework directly in Linked Framework and Librairies</li>
  <li>Deintegrate pods, delete DerivedData celan build etc ...</li>
  </ul>
  
  <p>But every time a build the entire workspace, I have this <strong>"No such module RxSwift"</strong> from a Project2 file.</p>
  
  <p>Do you have an idea of anything else I can check / try, or something I did wrong ? </p>
  
  <p>I'm using <strong>Xcode 9.1</strong> and <strong>CocoaPod 1.3.1</strong></p>
  
  <p><em>PS : my workspace is composed of 5 project set as local pods dependencies, and I know that put every thing in one project would surely fix this but what a mess I'll have.</em> </p>
  
  <p>Thanks ! </p>
