It is, but perhaps I'm not understanding how it is currently implemented. I thought there was a system framework it relied upon, and if so, that framework would need to be implemented in Darling. Perhaps the framework is embedded in every .app package? There's a similar issue with the Swift runtime. I believe Apple's goal is to make it a system framework, at which point it would also need to be implemented in Darling.
