According to Quinn “The Eskimo!” at Apple Developer Technical Support, this message is Xcode log noise and can be ignored.
An Apple bug report should be filed to help flag and silence the log.

It’s important to keep an eye on log messages and fix any obvious problems they call out. However, if you see a log message that’s not obviously your fault, it could just be log noise.
There are two criteria you should apply here:
- Is the log message associated with a specific failure? That is, when you see the log message, do you also see other problems?
- Is the log message written in terms you understand? That is, does it reference APIs or data that you’re using?
If the answer to both of these questions is “No”, it’s reasonable to conclude that the log message is just noise and you can ignore it. If you find it to be particularly irksome, file a bug report requesting that it be silenced.
