Cocoapod is stuck in analyzing dependencies,
Although the company's projects do not use cocoapod, some third-party libraries rely on other third-party libraries and use cocoapod to manage these dependencies. Therefore, when using some third-party libraries, cocoapod is still needed. Today, fork has a control on github, which depends on another control, so I installed the pod, but it has been stuck in analyzing dependencies. At the beginning, I still suspected that it was blocked, later I searched the internet and found the solution, the method of http://stackoverflow.com/questions/23006683/cocoapods-staying-on-analyzing-dependencies ranking first successfully solved my problem, the original xCode upgrade will be like this operation.
