Ole Zorn has just discounted Pythonista 3 to $4.99 over the holidays, which means you have zero excuses not to get what is (by far) the best self-hosted iOS development environment out there (for years now).
I cannot praise it enough (my kids started out coding in it, and love the app to the point where they have already delved deep into the native UI bindings), and I love the way it keeps getting substantial improvements.
On the other hand Editorial is lagging behind (it doesn’t even have iCloud Files support), and looks set to remain that way given that Pythonista brings in 50x more revenue.
Nevertheless, here’s hoping for Python 3.7 on the next Pythonista, and even deeper integration with Shortcuts.
