title: Error "No such module" when installed framework with pod in swift 3
body: <p>I had manually added Alamofire, realm and swiftjson framework in my swift project. At that time my project was working properly.</p>
  
  <p>Now I created a Podfile in my project directory and added the following pods</p>
  
  <pre><code>pod 'Alamofire'
  pod 'RealmSwift’
  pod 'SwiftyJSON' 
  </code></pre>
  
  <p>It is successfully installed.
  I opened .xcworkspace and tried to import the framework. But is showing error message "No such module Realmswift", "No such module Alamofire", "No such module SwiftyJson".</p>
  
  <p>Framework search paths are as follows:</p>
  
  <pre><code>$(inherited)
  $(PROJECT_DIR)/app_name/Frameworks
  $(PROJECT_DIR)
  </code></pre>
  
  <p>Even "Build Active Architecture Only" is set to NO.<br>
  How can I resolve this problem?</p>
