Python, a beloved language among developers for its simplicity, readability, and extensive library support, has traditionally thrived in the realms of web development, data science, and automation. However, as the mobile app market booms, the question arises: can Python applications be packaged and deployed on iOS devices? The answer, albeit not straightforward, is a resounding “yes,” albeit with some caveats and workarounds.
Introduction to the Challenge
iOS, being a closed and tightly controlled operating system, does not natively support Python execution. This means that running a Python script directly on an iPhone or iPad is not feasible. However, developers have found creative ways to bring Python’s power to iOS devices, often leveraging web technologies or leveraging the capabilities of frameworks designed specifically for this purpose.
Methods for Packaging Python Apps for iOS
-
Web-based Approach (PWA or Hybrid Apps)

- One approach is to create a web application using Python-based frameworks like Flask or Django, and then wrap it into a Progressive Web App (PWA) or a hybrid app using frameworks like Cordova, React Native, or Flutter with a WebView component. This way, the Python backend serves the application’s logic, while the frontend is rendered natively on the iOS device.
-
Kivy with Kivy-iOS
- Kivy is a popular open-source Python library for developing multi-touch applications. With the help of Kivy-iOS, a project that aims to port Kivy to iOS, developers can create native-like iOS apps using Python. However, this method requires a deep understanding of iOS development concepts and the ability to compile and sign the app for distribution.
-
BeeWare Project
- BeeWare is a community-driven initiative that aims to bring Python to native desktop, web, and mobile platforms. While BeeWare’s support for iOS is still in its infancy, it holds promise for the future of Python on iOS. BeeWare allows developers to write their applications in Python and then compile them into native binaries for various platforms, including iOS.
-
Pythonista and Carnets
- For those looking for a more straightforward and immediate solution, Pythonista and Carnets are two popular iOS apps that allow users to write, run, and share Python code directly on their devices. These apps provide a limited subset of Python’s capabilities and are primarily aimed at education, experimentation, and quick scripting, rather than full-fledged app development.
Challenges and Considerations
- Performance: Running Python code on iOS devices can be less efficient than using native iOS development languages like Swift or Objective-C, especially for computationally intensive tasks.
- Limitations: Many of the methods mentioned above come with limitations, such as restricted access to iOS APIs, limited support for external libraries, and the need for workarounds to simulate native behavior.
- App Store Approval: Submitting an iOS app that relies heavily on Python or its frameworks to the App Store can be challenging, as Apple has strict guidelines for app submissions.
- User Experience: Ensuring a seamless and native-like user experience can be difficult when working with frameworks that are not designed specifically for iOS.
Conclusion
While packaging Python applications for iOS may not be as straightforward as for other platforms, it is certainly possible with the right tools, frameworks, and a bit of creativity. Whether you choose to go with a web-based approach, leverage Kivy-iOS, keep an eye on BeeWare’s progress, or use Pythonista and Carnets for quick scripting, there are options available for bringing Python’s power to the world of iOS.
As I write this, the latest version of Python is 3.12.4
