Clear enough for you?
Game sharing as on the ps3 is no longer an option but it is still possible.
Step1: You and your friend each get a ps4 and set it as your primary
Step2: Swap ps4's and login as a secondary account.
Step3: Both you and your friend have access to your own and your friends psn games.
Also only 1 of you will need PS+ and both will have access to it.
