CocoaPods takes a set of specifications to generate and setup a series of libraries which include the dependencies of the targets of a given project. Sunday, 29 September 13 Setting the context and explaining the basics with some emphasis on some less know point. - The Podfile is about targets. Don't get confused by the implicit target definition. -The Lockfiles, especially the Podfile.lock is as important as the Podfile and as accessible. -Specifications will be only declarative.

Why? Sunday, 29 September 13 - [Joke] You might want to use this dependency automation thing unless you prefer your to use punch cards for that (apparently some still do). - Even if you're not a fan you might learn some tips and best practices for your workflows. - Abstractions are leaky - CocoaPods is still very immature - Life is good until CocoaPods breaks your project and suddenly all those little ponies reveal o be nothing else than overgrown rabid zombie rabbits - Adapt CocoaPods to your needs - Better tickets - Less blaming on maintainers ;-)
