Apple uses no Turing complete policy. So you also can't bundle a python or ruby interpreter in iOS. Its still anti-competitive but in a different area which is language and api. They are basically trying to push devs to use their native OS apis. PWA are also screwed up in Safari for a reason.

That’s surely absurdly difficult to test, and provably impossible to prove the negative (i.e. my app is not Turing complete.) Is a calculator app not Turing complete? What about Google Sheets?

  As long as it uses Apple's WebView, it's OK. This was the case for Firefox, they had to ditch Gecko in favor of using Apple's webview for iOS.

Pythonista is a full(-ish) offline Python IDE and has been on the App Store for years.

This is not true. There is for example the Pythonista IDE for iOS, which ships a full Python interpreter. https://omz-software.com/pythonista/ https://omz-software.com/pythonista/

  Is there an example of a non development/learning tool?

    If I remember correctly there’s an exception for learning and development tools.

Kivy bundles Python in iOS apps, and the apps are accepted on the App Store. Do you have a link for this policy?
- saagarjha 7y ago
  That likely falls under the “educational” exemption: https://developer.apple.com/app-store/review/guidelines/#software-requirements https://developer.apple.com/app-store/review/guidelines/#sof...

    That's unlikely, Kivy is also used for commercial apps. Bundling interpreters is allowed, but you must not use them to execute arbitrary code, unless you do it for educational purposes. Kivy doesn't load remote code, so it's not affected by this policy.

      Then apps using it must ship all of their Python code in the app bundle to meet the App Store Review Guidelines.
