For me I have to use the USDZ Tools written in python 3.7 on the x86 architecture. I could not find any alternatives that converts USDC binary file into USDA Ascii format. I tried PythonKit which require you to remove the sandbox. I tried portable-python which always results in errors, possibly due their build script. To conclude, I would love to use an USDZ Tools built for Swift or even C, but it simply does not exist. So I had to resort to trying to have a python environment in Swit, eventhough it sounds unreasonable and should be avoided.

I am trying to convert USDC files to USDA format then pack them into an USDZ file. USDZ Tools works perfectly for me after installing python 3.7.9. I wish to include this convertion in my App, which is written in Swift to use the photogrammetry API. But I can not find a way to include python 3.7 x86 executable/framework in the app. I tried PythonKit but cannot find a x86 3.7 framework to include, and I tried portable-python but the build always fails due to their build script. Does anyone have USDZ Tools (Specifically usdzconvert and/or usdzip) alternatives that runs in Swift App's sandbox?

I tried to use the portable-python tool to build a live python executable, so I can put this executable in the app sandbox folder. You can have a try, but in my use case where I have to build an x86 python 3.7 for USDZ Tools, it always results in errors. Might because of their python build script. I found in PythonKit docs it mentioned you have to put python framwork into sandbox folder to make it work, but I didn't find a way to build the framework. So, same problem here. Any potential work-arounds?
