Yes, it's a good thing you're writing.
We're removing the xcode 9.2 support. The main problem is that we need to upgrade Mac OS to the latest version to install the current version of xcode. Unfortunately Apple (as is its custom) no longer supports xcode 9.2 in newer versions of the OS so we can't run the old xcode anymore. I hope to put out a blog post on the matter over the weekend.
