Update Podfile like this and check

target 'App' do
  pod 'Alamofire'

  target 'Demo AppTests' do
    inherit! :search_paths

  end

  target 'Demo AppUITests' do
    inherit! :search_paths

  end  
end

If your problem is not solved after trying @Naveen's answer and you have Obj-c bridging-header in your main target, you should create another briding-header with the same values for your tests.
