This was redundant, echoError writes to stderr right above this.

Stop printing the Xcode output when we have more specific error to display, to reduce noise

So the assumption is that the actual error was already echo'd by xcode_backend?

Yes, that because the build failed there will be at least one error message from Xcode that will be parsed and already shown. That includes any failure from assemble, including a dart compilation issue.

Removed some of the irrelevant parts of the output of these tests to make it more concise.

Nifty and totally undocumented, I don't even remember how I learned about this.

should this be logger.printError?

This was just moved, and it was printStatus before. Not sure why and I don't really want to change it now... Hopefully we almost never drop back to this fallback.

assemblestderr witherror:to make them show up as compilation errors in the Xcode UI and the parsed XCResults. Example dart compilation error showing in Xcode:Treat
assemblebuild system exceptions as fatal, but only show stack traces in verbose mode. As far as I can tell noExceptionMeasurementwas ever fatal, so only showing stack traces in verbose mode shouldn't suppress previously displayed stack traces, since there were none. See Don't log stack traces to console on build failures #44966 and [flutter_tools] Allow the tool to suppress compilation errors. #58539 for some of the history of that TODO.Stop showing the final x stderr and stdout lines of the Xcode build, unless the xcresult can't be parsed. This should reduce the noise in the build failure.
Stop showing the "missing development team" message when there is a more specific error to show.
This should make triaging issues easier, since the build error will be visible and obvious without
