Cannot get started writing a C++ Xcode plugin from scratch

Hello everyone,

I am getting started in Photoshop plugin development, i am a C developer but even with the documentation I cannot understand at all how Photoshop Xcode projects works, I'm trying to have a basic "from scratch" project by creating a macOS bundle (exported as a plugin), added the necessary infos in info.plist (like the plugin type) and a minimal PiPLs.json is /Ressources/ 

But I cannot get the plugin to even show up at all in the list of filters, the PluginMain function doesnt do anything particular, and i'd like to understand the requirements so a photoshop plugins shows up in the filter list. I could not understand that from the example projects.

Thanks a lot !

(Photoshop 2026, ,macOS,sdk 2026 v2)
