title: Cocoapods: Unable to find a specification for `PUBLIC POD` depended upon by 'PRIVATE POD'
body: <p>I keep running into the error specified in the title. I am trying to deploy private pods by this tutorial: <a href="https://medium.com/onfido-tech/distributing-compiled-swift-frameworks-via-cocoapods-8cb67a584d57" rel="nofollow noreferrer">https://medium.com/onfido-tech/distributing-compiled-swift-frameworks-via-cocoapods-8cb67a584d57</a> the problem is that the framework I want to deploy has <strong>one</strong> dependency. And due to that dependency I am getting this error, although I have already tried things like: <code>pod repo update</code> and also adding <code>source 'https://github.com/CocoaPods/Specs.git'</code> along with my private repo source in a test projects Podfile.</p>
  
  <p>My current cocoapods version is 1.9.1.</p>
