Swift reminds me a lot of Flash back in the day.

While the Flash guys had to use a native development environment and compile their stuff, I could just edit JavaScript in a plain text file and hit reload.

20 years later, and some of the same friends now swear by Swift. And have to use a native development environment and compile their stuff. While I still prefer to just edit JavaScript in a plain text file and hit reload.

Given that Swift has one of the slowest compilation times, this is a valid criticism.
