What is a correct way to start a swift scenekit project in xcode11 targeting 12.4 platform?While doing things as usual i get following error about UIScene not being present on 12.4"/SceneDelegate.swift:16:100: 'UIScene' is only available in iOS 13.0 or newer"in total 15 errors in the following file:// // SceneDelegate.swift // Scene-kit-12.4 // // Created by Alex on 26.09.19. // Copyright © 2019 Home.
