The best thing about cocoapod's library management system was that it made building iOS apps easyer, I used to write code manually but now its done by me automatically without any error messages or warnings! There are so many different libraries out there which make your life easier when you want some new features in an app like location updates etc., You can easily find them with just one click!! Sometimes if i am using multiple frameworks at once then sometimes my project starts giving errors even though all of these were installed properly through CocoAopds itself.
It also helps us keep track what files have been updated from where as well!!
