I just upgrade from Visual Studio Enterprise 2017 version 15.6.6 to 15.9.11. I then upgrade my MacBook Pro to High Sierra 10.13.6 and installed XCode 10.1. I've selected 12.1 as the SDK version under Build. I'm getting the following error when submitting my application using Application Loader.
WARNING ITMS-90725: "SDK Version Issue. This app was built with the iOS 11.3 SDK. 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 old version of the SDK was 11.3. Any idea why Application Loader still thinks the app is being built using version 11.3 of the SDK?
Any help is much appreciated! Thanks!
