I was enthusiastic about early TensorFlow in Swift efforts, sorry when the effort ended. My interest then flowed into early Mojo development for a while.

I wrote an eBook on Swift several ago but rarely update that book anymore. Count me as one of the many developers who for a while thought Swift would take over the world. At least Swift is a fun language to use, and now with LLM coding tools writing macOS/iOS/iPadOS apps is fairly easy.
