That is what is in your Xcode app. Do you have any 3rd party libraries or frameworks in your app? What SDK are those using?

I am using cocoa pods to install the 3rd party libraries and dont have any added directly.

I used an other mac with xcode 11.1 and was able to upload the build is it something to do with version of the X-Code

It doesn't matter where they come from. They are your responsibility.

I've the same code, same XCode. I just did some minor update to the code, now I cannot submit my app to the app store due to this issue

"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 12.1 SDK or later, included in Xcode 10.1 or later. Further, starting June 30, 2020, iOS app updates submitted to the App Store must be built with the iOS 13 SDK or later, included in Xcode 11 or later."

I did successfully upload my app last week. Don't know what happen witth Apple back-end 😟

I got solution now.

I clearn this directory '/Users/longcao/Library/Developer/Xcode/DerivedData'

Then archive the app, then I can validate and upload my app to the app store.
