Is this framework still supported?

I am having difficulty trying to figure out how to use the Selenium.framework. The README has a link to Appium.app which is deprecated and in the Appium Boneyard. Should this be moved to the boneyard too? Objective C is not even listed as a supported client language on the Appium site. http://appium.io/docs/en/commands/web/storage/get-all-cookies/#appium-clients
