I’ve got all the usual suspects such as achievements and high scores working. I’d like to save these values locally in case of network issues, etc. I created a test app and built it with the same dev profile. I’m using the GGGameCentre module from GlitchGames. Anyway, while watching the console output in Xcode I never see the player getting loaded. The code is basically straight from the example except for the listener which I found elsewhere on the forums. Note from the output below that I can see the init phase and the login phase. I also see the gamecenter “welcome back” banner in the app. I’ve tested this with an iPad Gen 1 5.1.1 and an iPhone 4 6.1.2 I know I must be missing something and it’s probably staring me right in the face. BTW, if I use the lua code tags all of my spaces in the preview are shown as  
local GGGameCentre = require( “GGGameCentre” )
function requestCallback( event )
print
print(“requestCallback”)
for k,v in pairs(event) do
print(k, v)
end
if event.data and type(event.data) == “table” then
for k,v in pairs(event.data) do
if type(v) == “table” then
for k2, v2 in pairs(v) do
print( k2, v2)
end
else
print( k, v)
end
end
end
end
local gameCentre = GGGameCentre:new( requestCallback )
gameCentre:loadLocalPlayer()
console output from Xcode
