Hi, my name is Murakami from Bitz.
As described in the "Submitting iOS Apps to the App Store" page:
https://developer.apple.com/ios/submit/
Update to Xcode 10.2, which includes the iOS 12.2 SDK, and build your apps. Starting March 27, 2019, all iOS apps submitted to the App Store will need to be built with the iOS 12.1 SDK or later, and support the all-screen design of iPhone XS Max or the 12.9-inch iPad Pro (3rd generation).
You can read that the submissions need to be built with the iOS 12.2 SDK or the iOS 12.1 SDK, but which one do you need to build?
Is there anyone who applied for apps built with the iOS 12.1 SDK since March 27, 2019?
I see, thanks.
You would be ok to build and upload with Xcode 10.1
