Exercise 2: Ending Style Arguments With a Linter — Possible Solution
====================================================================

TASK
Say which tool addresses the argument, how you would install and wire it
into an Xcode project, and what you would do before the automatic fix.

ANSWER
Tool: SwiftLint, which enforces Swift style and conventions and has over
200 rules covering naming, structure and style.

INSTALL
  brew install swiftlint
(The repository also lists Swift Package Manager, CocoaPods, a pre-built
package and Docker.)

WIRE IT IN
The repository describes two routes for Xcode: a build tool plugin
(described as recommended for modern projects) or a Run Script build phase.
On an Apple silicon Mac with Homebrew you may need /opt/homebrew/bin on
your PATH.

CONFIGURE
Put the team's agreed rules in .swiftlint.yml using disabled_rules,
opt_in_rules or only_rules.

BEFORE swiftlint --fix
It edits your files, so commit or stash your work first and read the diff
afterwards.

CAUTION
I did not verify individual rule names against the current list, so pick
them from SwiftLint's own rules page.
