I've been watching a 2019 Developer Video "Building Apps with RealityKit" and working along with it. It shows how to create a custom entity. It shows how to load entities from .usd files. How do you either load a custom entity, convert an Entity to a custom entity, or maybe move model hierarchy from an Entity to a custom entity? I assume there's a way to do this.

Is there an easy(ier) way to work with skeleton tracking? I have an iPad on a stand and I am the model most of the time. I can't stand in front of the camera and see what's on the iPad. I don't think I can use the front camera for tracking. My wife is getting very tired of "Honey, can you come here a minute?"
How is this supposed to work?
I'm using playground to experiment with Combine. I found this example on a blog. I expect it to create the Future publisher, wait a couple seconds then send the promise and complete.
import Foundation
import Combine
import SwiftUI
let future = Future<Int, Never> { promise in
print("Creating")
DispatchQueue.global().asyncAfter(deadline: .now() + 2) {
print("sending promise")
promise(.success(1))
}
}
future
.sink(receiveCompletion: { print("receiveCompletion:\($0)") },
receiveValue: { print("receiveValue:\($0)") })
print("end")
The output I expect:
Creating
end
sending promise
receiveValue: ...
receiveCompletion: ...
The output I get:
Creating
end
sending promise
I don't see an indication the promise was executed. What am I doing wrong?

I've wriiten a simple app that runs on a single iPad running os9. This app crashed recently because a "Apple Worldwide Developer Relations Certification Authority" needed renewal.Will this be needed every few years to keep this app alive? It's running on an old iPad because it's free and would be in a landfill if it wasn't being used here.Is it possible to create an app that is not meant to be distributed and have it just run as long as the hardware functions?

I’ve been trying to install the new update and I’m always ending up on the recovery screen. The installer log says the disk is not compatible with APFS, claiming it’s not Mac OS Extended. Disk Utility says it is Mac OS Extended ( Journaled ). I been running High Sierra beta for a while, including converting to APFS some time ago.i Thought I’d backed the MBP a couple weeks ago, however the lastest backup on my Timemachine drive is dated April.Using terminal I manually backed up my user directory and Applications.I‘ve been using Xcode to write several programs. The projects are in my home directory. Are there any other directories I should backup before reformatting and resetting back to april?I‘m making a bootable thumb drive with high sierra think I can get time machine running and make a current backup before reformatting.Has anyone had similar problems? Any suggestions on how to proceed?
