Differences BW Facebook Login and FBSDKLoginKit Pod and which one to use?

Question

I was trying to integrate facebook login in my iOS app. I am reading the official docs for this purpose.

On this getting started link. Documentation say to use the following pods

pod 'FacebookCore'
pod 'FacebookLogin'
pod 'FacebookShare'

So i understood that i have to use pod FacebookLogin and that's it.,

BUT

On this iOS login Docs page, Docs say to use

 pod 'FBSDKLoginKit'

1. I am totally confused about which one to use.
2. What's the difference between the two?

Note: I just want to perform facebook login in my app and nothing else.

If you are using swift then use 'FacebookCore' and FacebookLogin'. For objective C use 'FBSDKLoginKit'. But if you see internally in podfile, they use objective C code via bridging.
