Depends. I usually set a marker around 90 and mostly stay inside it. Func&#x2F;method type signatures (especially in Swift&#x2F;ObjC) I&#x27;ll let run over without worrying as they can get a bit verbose and I don&#x27;t need to parse them frequently.<p>Inside the body I&#x27;ll usually stay under 75 and will split multi param function calls across lines. If lines start to overflow I&#x27;ll often factor some piece out to another variable to keep it readable.<p>Switch cases I&#x27;ll let run long  if I can fit them all in as one liners. Having not worked on a shared code base for a few years I&#x27;ve developed a bunch of non standard habits.
