I'm not able to submit an app to TestFlight because the Apple service is considering that I'm using a beta version of Toolchain. This started to happen after upgrading to the latest version of Xcode 10.1 (10B61).
[18:07:19]: iTunes Transporter output above ^
[18:07:19]: ERROR ITMS-90534: "Invalid Toolchain. New apps and app updates must be built with the public (GM) versions of Xcode 9 or later, macOS, and iOS SDK or later. Don't submit apps built with beta software including beta macOS builds."
Return status of iTunes Transporter was 1: ERROR ITMS-90534: "Invalid Toolchain. New apps and app updates must be built with the public (GM) versions of Xcode 9 or later, macOS, and iOS SDK or later. Don't submit apps built with beta software including beta macOS builds."
The call to the iTMSTransporter completed with a non-zero exit status: 1. This indicates a failure.
Anyone else with this problem?
