var spawn = SKAction.runBlock self.spawnPipes if var == true {...}
if (<expression> == true) {
return true;

return false;
}
if var == true {...}
However in the strongly typed swift I don't think it will be a problem as I suspect (but haven't read/tested enough yet to confirm) that only false and nil will be falsy and that comparison with true will throw errors if var isn't of bool type.
3 == true // Give an error (operator overload doesn't cover this)
true == 3 // Returns false
nil == false // Returns false
But the branch and explicit boolean comparison are additional structural complexity (not just "verbosity") and invariably harms readability to me. Care give a poster child example for where it helps readability? Unless it's unclear <expression> results in a boolean - a problem better solved through better naming - code like this forces me to perform the equivalent simplification in my head to understand and reason about the code, a process fraught with error and distraction from my actual task.
return expression;
