Well I decide to write a barebones SwiftUI implementation with MCSession and without a MCBrowserViewController nor UIHostingController. Seems to work. you can find it here: MultiPeer

Same here, MBP now bricked. Stuck at update screen. Am in Bali, nearest Apple Store is a flight to Singapore. Not a happy camper.

TL;DR - erase hard drive. Reset won't work. Will revert production (non-beta) over internet. Upgrade to MacOS 14 overrides MacOS 13.4 on internal hard drive. So, reset will clear out everything and start from the internal MacOS 14 install image. Apple support suggest swapping out hard drive. But, in Bali, that would take two weeks or a flight to Singapore. So, we experimented with erasing the hard drive. At that point, the workflow reverted to MacOS 13.4 install from internet Success!

Sorry, TL;DR was for another post about recovering from MacOS 14 install interdiction. Please disregard.

Can't share files. Are you using XCode 15 beta? Starting working after Beta 2. Now on Beta 5.

@2time.net Works! You're a life saver -- or at least, a few hours of life saver.

@RK123 am using import MultipeerConnectivity. The question had me worried, as am marshalling midi events to a visual synth. Just tested on iPadOS 17 Beta 5 with same result (not found)

Am blocked, until a 3rd party updates package for new test. In the interim, is there a way to spoof os(iOS) ?

This is awesome -- thanks!

I've closed FB12879060, as there is a new template in Beta 6 -- see answer from Apple Engineer, below.

Works, thanks! There were a couple other api changes that were easy to figure out. Updated example project SpatialMetal

Is there anything functionally equivalent in RealityComposer shader graph? I am rendering a cellular automata that double buffers a texture, where the output texture of one frame becomes the input texture of the next frame. This implies either custom [[visible]] void myShader(realitykit::surface_parameters params) { } circular reference in the shader node graph that can flip textures per frame callout to a Compositor.Layer renderer
