I am growing an app that strikes a “grid” with Spritekit SKAction.transfer, based mostly on frequent updates from ARKit. It crashes sporadically at digicam?.run(moveToAction). Generally the app runs for 10-15 minutes with out drawback so it is arduous to debug. I am pretty inexperienced and any assist is extremely appreciated.

The “level” appears to be because it ought to, I am having bother debugging this because it occurs sporadically and could be at decrease degree. It could be higher to not use transfer motion when it’s this frequent, however i discover it smoother than updating the place straight.
