title: React Native - iOS - Invalid `Podfile` file: undefined method `[]' for nil:NilClass
body: <p>I have just started out with React Native. I was following the React Native CLI Quickstart from the official documentation. That does also mean I am up to date with React Native version <strong>0.61.2</strong>.</p>
  
  <p>Since then I have done some basic UI, checking with the result in the iPhone simulator. It works when running <code>react-native run-ios</code>, not really touching the <em>ios/Podfile</em> too much.</p>
  
  <p>My problem is running <em>pod install</em> inside my <em>ios/</em> folder always results in an error! This becomes a problem now where I need to install additional packages. But it is already failing with default Podfile!</p>
  
  <p><strong>Error message:</strong></p>
  
  <pre><code>[!] Invalid `Podfile` file: undefined method `[]' for nil:NilClass.

  <p>I have no idea how to deal with this! I have no idea how the Podfile and the thing with the xcode files really work! I was trying to delete folders accomplishing a reset. More than that I have no idea what the error message could mean.</p>
