Hi, Apple released XCode 9.1 on 10/31/2017. When will you have an image for building iOS apps using Xcode 9.1? This version of XCode is not compatible with XCode 9.0.x, meaning frameworks built with one of these cannot be used with the other version of XCode. We’d like to move our project to XCode 9.1, but since we use CircleCI for our builds, we cannot make the transition until CircleCI supports XCode 9.1. Thanks, Maksim ---
