I just upgraded to Xcode 4, deleted the OpenFeint folder and added the new 2.9.1 framework according to this readme. Then I deleted the "build"-Folder (that is now located in ~/library/Developer/...) and rebuilt the application but always get the following error:
/Users/k****/Documents/Tactica/Tactica_Prefix.pch:5:30: error: OpenFeintPrefix.pch: No such file or directory
When I have a look into OpenFeint.framework/headers there is clearly a file "OpenFeintPrefix.pch" included.
Any Idea why Xcode doesn't find it?
