If you read the link I shared above, you’ll see there are pre-defined folders. You have to put them accordingly.
And there is more:
You have two options here. You can copy the source code of this project into a Defold native extension and set it up, letting the Defold build server handle the building. Or, you can build this project in Xcode as a library and add it to the native extension accordingly. I recommend you to go with 2. option.
I would choose option 1 since I don’t own a mac and not familar with macos and ios so I don’t have skills to build it as a library. Can you please more specific which folder of extension I can put the library code into it?
Sorry, this is not an easy task; it requires time and effort to examine the project you’ve shared. I don’t have that much time to dedicate to this project, but maybe someone else can help.
