Integration of cocoa packages with app extension

I am working on a project with cocoa pods integration.

Content of my swap content as below

platform :ios, '8.0'

pod 'AFNetworking'
pod 'MBProgressHUD'
pod 'HDTableDataSource'
pod 'HDCollectionDataSource'
pod 'HDAlertShortkut'
pod 'TouchXML'
pod 'ARAutocompleteTextView'
pod 'AMTagListView'

link_with 'ApplicationName', 'ExtensionName'

      

        
        
        
      

    

My code is in Objective C. The problem I am currently facing is I cannot import the AFNetworking library in the extension controller.

Please help me to solve the problem.
