I don’t know if this is true or not, but Apple certainly isn’t writing its own end-user applications with good macOS technologies and support (which means it’s not using Objective C and Cocoa). Apps like Reminders, Notes, Photos and others on macOS seem and behave like poorly ported versions of an iOS app.
