@prateekguptaiiitk Why deintegrate is necessary here?

pod deintegrate helps to remove all traces of Cocoapods from the project. So after that if we do pod install we can start to install them afresh. pod update will solve any version inconsistencies. Without pod deintegrate project was throwing random build errors.

@prateekguptaiiitk pod update will cause the CocoaPods to update libraries even if they're not in the same version as in Podfile.lock, right? It could cause some inconsistencies between projects in this case I think. Just pod install should be enough for anyone cloning the project, but most of the time that's not even necessary because the Pods folder is already being cloned.

Have you experienced any problems cloning the app for the first time and running it?

Yes @rafaelks I along with some others experienced problems while setting up the project for the first time and running it. Even running pod install didn't help. When I ran pod deintegrate and then pod install my problem was resolved and project was built successfully.

While I didn't experience any problem setting up the project for the first time, as the Pods were already there, I think the problem is usually with updating swiftlint and fastlane.
