How do I add a friend to game center in IOS 10?

I wanted to add that this is causing problems because there are games that require large numbers of cooperative activity between members (100s of people). This is the kind of activity that does not work well in Messages or Facebook. It is really difficult to manage in regard to confidentiality of our personal information. Apple really has screwed us all over!

now Apple's devices & other devices r the same to me,,I will no longer buy any iOS device in futur.

i Really liked Game Center app & liked what offered now I have no interest in games or iPhones,,bye Appl..

By removing the Game Center app, they have completely killed my interest in iOS gaming. I will be selling my iPad Pro, and replacing it with a PlayStation 4 very soon.

Once again, their "update" makes things obsolete and encourages those of us with devices older than 6 months to look elsewhere. This is such a forward thinking business model, Apple. I hope it goes well for you, but I, too, will never purchase another Apple product. I'm over your self inflated thinking and lack of customer service. Steve Jobs must be rolling in his grave with what is happening there. Or maybe not. I don't even care anymore.

Got to say I'm astonished... been fiddling all day with settings as all friends missing from real racing app... ALL, now it seems those contacts in game CENTER are lost forever as I have no way of contacting them outside of gamecenter . This!!! Along with the nonsensical cables monetisation has taken the shine right off Apple. Epic fail, so poorly managed. 5 yrs of socially acquired best of players... Gone. I will not be purchasing an iPhone for a long time.

I can't believe that apple was that st

*stupid

How do I send it through iMessage though??

I agree with you...

WHY ITS DOESNT WORK

But with an ipad is it possible? If yes, how?

I want delete the clash royale game data of game center for start of zero.

This has been the worst thing to happen on my iPad. You know all the games I didn't login to with Facebook, that I lost all my data, all my purchases, and its total crap. Not that I planned to play those old games, but whoever said "hey lets remove our entire gaming infrastructure and just let each individual app decide. Only worst "friend system" is 3DS.

Why don't they add it back? I can no longer manually force it to sync my data to get it back. I've lost my data for a couple games and need Game Center to help, go figure it's been deleted!

My Dad has an older iPad and still has the Game Center app. When he sends me an invite to be his friend, I never receive it! This doesn't seem to work and Apple needs to reconsider this.
