IOS11 ARkit?

Every Engine has serious issues with Xcode, and support. Beta is even worse. I’ve been skipping this Arkit beta for about another month.
Right before the great Iphone release. Everything will be fuunctional.
When the official Xcode beta ends. I guarantee you. Xcode will say. No new source files needed.
Then. You have 258 new compiler errors. A build only device cannot be run to use this target. Could not locate device support files. App installation failed.
Apple creates p8 certificates, and then decides p12. At the next Alpha build of xcode. You may see p14.
As if trying to compile isn’t difficult enough. Xcode must really enjoy saying deprecated. It’s the most hated word in my life.
