Since Saturday Dec 28th 2019 (about 10am PST) I am no longer able to submit a build for testing in TestFlight, the error I receive is:
ERROR ITMS-90725: "SDK Version Issue. This app was built with the iOS SDK. All iOS apps submitted to the App Store must be built with the iOS 11 SDK or later, included in Xcode 9 or later. Further, starting March 2019, all iOS apps submitted to the App Store must be built with the iOS 12.1 SDK or later, included in Xcode 10.1 or later."
The steps I take are, Open Xcode, Product -> Archive and then just click through the process to auto-sign etc. and upload. I am running Xcode 11.3 and tried building for iOS 12.0 / 12.1 & 13.2 all result in the same error since Saturday 12/28 10am PST.
I've gone back in our git history and synced to the code last submitted on 12/26 and bumped the build number and get the same error, I deleted the entire project folder and cloned the repository again to no avail, rebooted my system still no dice.
So I did another test, ran 'Validate App' from Xcode on a previously succesfully submitted App build and it failed with two errors, build number re-use obviously but also the same SDK version error!
Happy new year to all! 🙂
