I am trying to create my first pod and is following this tutorial: http://www.sitepoint.com/creating-cocoapods/
But when I do:
pod spec lint GLLingoM
You have pointed to a branch called 0.1.0 in your podspec, and you simply need to push a branch of that name to github. Many people use tags instead of branches to indicate which commit to use for each pod version, and I suggest that you do this instead of pointing to a branch. Please post the source section of your podspec for more specific details.
