I’m seeing just in the past hour a message when attempting to upload a production build. The message is
INFO ITMS-90111: “Invalid toolchain. New apps and app updates must be built with the public (GM) versions of Xcode 6 or later, and iOS 8 SDK or later. Don’t submit apps built with beta software”.
I don’t believe anything changed with respect to my osx environment I use to build. I tried the latest daily build and still get the same message.
