Honestly, I try to write code on iOS all the time, and it's not really the absence of tools that can execute that code that really stands in the way. Instead, it's:

- The absence of a really good typing story. The 12.9 iPad Pro with smart keyboard is nice for typing text but terrible for moving the cursor around. It's agonizingly slow to do it with keyboard (highlighting is worse, for some reason) and inaccurate to do it with finger/fiddly to do it with Pencil.

The only text editor with vim keybindings (an absolute must in an environment where it's hard to move the cursor normally...) of which I'm aware is Buffer, while the only text editor with both good syntax highlighting and good github integration (via Working Copy) is Textastic. Honestly, I really wish one of those two would just buy the other so that I could have both.

- The absence of a really good ssh story. Prompt is nice, but for some reason, whenever I try to SSH into anything, there's so much latency that it is really painful to actually do anything. Maybe I just have slow network connections? But anyway, so much for just coding on a linode or something in vim.
