Disabling The Swiftlint rule "Trailing Comma Rule" on code level "Rule.swift:24" will simplify the source diff in a code review (one added line instead of one removed line and two added lines) and will mark the "allRules" collection as a collection open for new elements.
I would use the comma where you know you're going to add elements later, and omit it if the list of items is final.
