The use of ``++self++`` is optional except when in closure expressions, and when it's needed to distinguish between property names and arguments. For the sake of brevity, ``++self++`` should be omitted when it's not strictly required. == Noncompliant Code Example ---- class Car { var color: Int init(color: Int) { self.color = color } func fade() { self.color-- // Noncompliant } } ---- == Compliant Solution ---- class Car { var color: Int init(color: Int) { self.color = color } func fade() { color-- } } ----
