Retrieving user's email Google Login iOS - ios

Question

I am trying to find the email of the logged in account from the google login API in iOS using Swift.
The code i used is the same as given in the google Developers instruction page.
This is my code
description = [NSString stringWithFormat: #"%# %# %# %# %# %#",
person.displayName,person.gender,person.ageRange.min,person.ageRange.max,person.emails,person.birthday];
The output when i print this "description" id is this:
Karanvir Singh male 18 20 (
"GTLPlusPersonEmailsItem 0x7fbe4a67aee0: {value:\"karanvir95#gmail.com\" type:\"account\"}"
) (null)
I want to know how i can remove the excess of output when i just want to know the email ID
i want the output as such:
Karanvir Singh male 18 20 karanvir95#gmail.com 17/02/1995
