Description

I occasionally come across code like this:

if condition == true { … }

which just be written as:

if condition { … }

I'd love to have a rule that disallowed == true and == false. (And != true, != false, which I haven't seen, but would be far worse.)

Research direction

Start by locating SwiftLint's existing rule implementations and tests for comparable equality or boolean-style checks. Add coverage for == true, == false, != true, and != false, with done defined as the new rule reporting those explicit comparisons without reporting the simplified boolean form.
