Back in my day, we programmed by flipping switches on the console...

Chris, tools are tools. We use SwiftLint on our projects because we, as a team, decided we wanted to codify certain programming standards and formatting across a very large project.

It will, for example, throw a warning when someone force unwraps a variable, and that warning tells the developer they need to cleanup their code before it hits code review. And before someone in code review dings them on it.

You might argue that it makes someone "lazy", but I'd argue that when a project reaches thousands of files and hundreds of thousands of lines of code... that we need all of the help we can get.
