Hi have a projets(including app extension) using cocoapods. (with Parse, Bolts, etc library).
All work fine before (using bolts 1.1.5 library), but, when i\'ve run a
Cocoapods are very useful (I'm sure), however they are designed to work with Apps, not App Extensions, and ultimately you lose control of the features they introduce during an update, so you will need to be more judicial about what versions of libraries you do use, based on the APIs they utilize.
In the case of Bolts 1.2.0, it's obviously decided to use sharedApplication, thus making it unsuitable for use in an App Extension.
So you will need to start using the libraries in source form, perhaps using git submodule for each one, that will allow you to update them when upstream is updated.
