Right off the bat, the author misses perhaps the best thing about this engine - it’s incredibly fast at prototyping ideas. This is obvious to anyone who has used it to try and make something.

It would help if the onboarding experience was smoother. Perhaps suggesting the ‘best’ instance based on speed, and if there are several randomize between the less popular instances. For normal people having to read about what an instance is and how to choose one will be a another barrier to entry, perhaps a deal breaker.

I am enjoying Swift.
