Will need to fix lint errors, but besides that it is ready for review.

Fix those SwiftLint errors plz 😬

This PR has been around for a while. I don't want it to become stale and out of date. Bring it up to date or resolve these items so we can get this merged when you can. Thanks for the work on this!

This is looking good to me as long as it's in the feature branch for now. Needs some visibility (user confirms downloading and running tools type stuff) before I think we release it. Just fix that lint error and I'll approve

[thecoolwinter]

Same thought as before, since this is a feature branch we'll need to continue iterating on this but I like the foundation. Still that lint error though.
