Setting SDK to 12.1

Question

I keep getting the warning:

This app was built with the iOS 11.4 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.

...when I upload to the app store.

I run Xcode 10.1, and I also set the base SDK to 12.1 as in the screenshot, but I still get the warning after archiving and uploading. Is there anything else I need to do? Deployment target is 9.0.

Answer 1

Just make sure you are using latest version of Xcode for compiling and uploading your build. Also make sure that you app screens support the all-screen design of iPhone XS Max or the 12.9-inch iPad Pro (3rd generation). Also check if all the pods are also build on latest SDK

I had 2 versions of Xcode (9 and 10) on my machine and after uploading I was also getting this warning. May be lame but once I removed Xcode 9 from my machine this warning went away.
