Having a bug in your code is never fun, but having a bug in your iOS game or app is even worse. You can’t just quickly fix it and hope nobody noticed. Your game has to go through Apple’s review process again, which takes time. Having a bug in your game just a couple of days before Christmas, can spoil your Christmas joy instantly. Apple is having a week off, meaning your bug will be in there for at least 2 weeks. The following Integer Overflow made me be angry at myself (and at Apple a bit). Don’t let it ruin your life.
