Lint with only non-correctable rules

Feature or Enhancement Proposal

Our team had an idea. We like the idea of having build warnings and errors in Xcode while writing code. However, for auto-formatting/correcting, we'd rather that happen at the pre-commit stage rather than while in the middle of working on a file. But, if we do that, then running SwiftLint during the build phase without --fix will cause the auto-correctable rules to be flagged as well.

What I'm looking for is a way to lint with only rules that are not correctable. I could modify the rules file and manually disable all the correctable rules, but when new rules get added later, we'll have to stay on top of this and it's a lot to manage. It seems like SwiftLint could make this an option fairly easily?

A general use case would be for any team that wants to use a separate formatter and only use SwiftLint for linting.

AFAICT I don't see an existing way to do this.

Start with SwiftLint's --fix handling and the rules-file configuration path to see how correctable rules are identified. The change is done when a build-phase lint invocation can select only non-correctable rules without manually tracking them, while pre-commit --fix remains available.
