Use of unresolved identifier 'GKPlayerAuthenticationDidChangeNotificationName'

It check if the player is logged in but it doesn't show the log in screen if the player isn't logged in!..

Hi I'm trying out the invite though it is not receiving. Is there any docs to help figure this out Thank you

BTW - awesome resource

Great helper class, thanks for that! Noticed a little bug in the authenticateLocalUser method, though: As apple states in their documentation, you should always check the authenticated-property on the local player, instead of relying on an error.

Also, if the view is not nil, there should be code to present the given view controller, so the user sees a login screen.

Thanks again!

I am trying to use your GCHelper and I put the line GCHelper.sharedInstance.authenticateLocalUser() in my AppDelegate but when I run the project on the simulator I get an error right away. I am new to Swift so I am probably doing something wrong. Any idea what I need to do to resolve this?

Thanks!

Hey!

Invites don't seem to work - what's required to get invite friend part working. :)

Cheers!

Should I register the localplayerlistener somewhere in the GCHelper authentication like this
GKLocalPlayer.localPlayer().registerListener(self)
so the app can listen for invites? I did't find such registration in the GCHelper.swift

I've noticed a typo in the
public func loadAllAchivements(_ completion: (() -> Void)? = nil)
function

It should be loadAllAchievements(_ completion: (() -> Void)? = nil)

Any possibility to add support for turn based matches? I tried myself and made a findTurnBasedMatchWithMinPlayers(), nearly identical to the non turn based one, but that was all I could come up with before things broke. If it's not too much work I'm sure a bunch of people would appreciate it! There isn't much info out there on turn based matchmaking.

I added the Repo to my project and try to authenticated the user but i always directly fail with

he requested operation could not be completed because this application is not recognized by Game Center.

Hi I created a bookseller who offers help like you for the game center. I wanted to know if it told you that we combine our two projects ? https://github.com/DaRkD0G/Easy-Game-Center-Swift

On commit 'e8f816ad06505de81de0af4945c4668281c30c80' changing 'NSNotification.Name(rawValue: GKPlayerAuthenticationDidChangeNotificationName) ' to 'Notification.Name.GKPlayerAuthenticationDidChangeNotificationName' caused builds to fail occasionally.

Hey! If you're here to write some unit tests, the only note I have is to use XCTest.

If you're not sure why I wrote this issue, go take a look at the CocoaPods Testing Jam.

Thanks!

hi, not a big deal, but just updated to Xcode 8.3 and I am using your (very cool) GC Helper.
Now seeing a few warnings related to it.

they are all:
String interpolation produces a debug description for an optional value; did you mean to make this explicit ?

as i say, not a big deal at all, just thought i'd mention it.

thanks for your awesome code.
