Caerbannog
This package embeds a Python interpreter into a macOS app. It also provides the support to allow a Python module to be written in Swift and be imported and called from the Python code.
To build a macOS app that embeds Python and allows calling into or migrating code into Swift, one adds this package as a dependency. Then, create a python virtual environment containing the required Python dependencies and sources. Embed the virtual environment as the Resource folder 'venv'.
A sample application using Caerbannog is in the github repository r0ml/CaerbannogSample
============================
- I need to embed the Python3.framework from XCode-beta in the application that uses Caerbannog because I can't embed it in the package
- I need to set the Framework search path in the application to include /Applications/Xcode-beta.app/Contents/Developer/Library/Frameworks/ because the Xcode-beta library path for included frameworks is not searched by default
- the "code sign after copy" option on the Python3.framework needs to be disabled (because the codesign fails)
- need to "disable library validation" on the 'signing and capabilities' tab because codesigning was disabled on the embedded framework.
- Create a virtual environment in the app, and pip install the necessary frameworks. Change directory to the root directory of the application and run 'python3 -m venv venv' followed by '. venv/bin/activate'
