I've encountered the same issue, it severely impacts my ability to store the test results for introspection.
As the temporary measure I'm no longer keeping .xcresult bundle, but processing it with https://github.com/XCTestHTMLReport/XCTestHTMLReport into an HTML file.
Hoping for a solution coming from tool specialists or an ability to customise logs archiving behaviour in next Xcode version.
