I'm sorry that I cannot provide any other information (or related code). If there are additional steps I can take to gather supplementary information I'm happy to do so.

This is a known issue called out in the Xcode 10.2 beta release notes. It's been fixed in the GitHub version of swift-5.0-branch, so you should expect it in a later beta!
