Analytics

You don't belong just tooling through the analytics and logs of the device. They don't mean anything to the average person without a program to read all the jargon in them. What makes you believe you were "hacked". iPhones themselves aren't really "hackable", though your accounts associated to them, without a strong password or 2 factor authentication certainly can be compromised. So... maybe explain more as to why you think you were "hacked".

That refers to a function call used by Apple. If you work for Apple you can consult various sites that will provide you information about those analytics. If not as nny1001 already said you will be totally lost.
