I just updated to Xcode 7.0 last night and it seems to have broken Receigen's generated code.
CFStringRef ReceiptValidation_str1 = @obfuscateCF@("");
Unexpected '@' in program
Receigen hasn't been updated since 2014, so this is almost certainly an Xcode 7 issue.
I reached out to the developer of Receigen and haven't heard back yet (it has only been a few hours). Any help would be appreciated.
See "Get Bundle ID from build settings instead of info.plist". I think it's the same issue, and I posted a work-around.
