Our app uses MKStoreKit for in-app purchases. We recently updated everything to iOS8 but we are having trouble building MKStoreKit with Xcode 6.
The file that is having trouble is VerificationController.m. We have the latest version from github. The build errors are in checkReceiptSecurity. Use of Undeclared Identifier ‘outLabel’
That same function also complains about encodeBase64 and decodeBase64.
See this question for the solution of the "use of undeclared identifier" errors in Xcode 6:
