iOS comes with a text editor built in. Memo.
Ssh server doesn't make sense for an iPhone. How would that even work? It wouldn't be able to do anything or be a worse experience than something properly designed for the user rather than trying to force a 50 year old computing model onto a phone.
Maybe iPhone is different but most phones you can connect a keyboard to, making the shell pretty usable. Not my cup of tea but I have tried it. I'm still holding out on the dream that a good Linux phone might exist one day.
