It’s amazing for him and it works on his iPad.
However when I tried it on my iPhone it was a broken mess. Completely unusable (not because of screen size differences).
I tried getting Claude to fix it but it couldn’t do it without changing too much of the look and feel, so I dug into the code and it was thousands of lines of absolute madness. I know from using this at work that there are things I could have done. Write tests to lock in things I like etc…
But so much of the speed up was about not caring about the specifics that once I started caring about making an actual product, I was not much faster maybe not any faster at all. The bottleneck in writing a game was never in banging out code.
Ask the AI to assess the code itself and to propose ways to gradually refactor it for better cleanliness. It can be good at that stuff, but you need to make it an explicit goal.
