I think visionOS 26 window state restoration doesn't interact well with pushWindow. (FB21287011, FB21294645)

Drew Olbrich @drewolbrich.bsky.social · 29/12/2025

There's also a related issue where if you pin the pushed window to a wall, it spontaneously disappears, and then pushWindow is forever broken for this and all other apps until the next device reboot.

I'm moving the child window, but the way it's supposed to work is that the parent window should later reappear in the child window's location. That's what happens if you launch the app from Xcode, but if you launch it from the visionOS home view, you get the behavior shown in the video.

(FB21287011) In visionOS 26.2 RC (23N301), when a window presented with pushWindow is dismissed, its parent window reappears in the wrong location

@tvaziri.com Hello, I require your expert opinion to settle an argument. Was the reflection of the chess board in Judd Hirsch's glasses in the Independence Day chess scene practical or was it CG? www.youtube.com/watch?v=ARNy... Thank you.

You probably saw this already but the WWDC25 session video "Bring your SceneKit project to RealityKit" developer.apple.com/videos/play/... says:

"...this year Apple is officially deprecating SceneKit across all platforms. ... This is a soft deprecation, meaning that existing applications that use SceneKit will continue to work. However, if you're planning a new app or a significant update, SceneKit is not recommended"

That's probably wise. I think if you've chosen to create a game of any complexity using either SceneKit or RealityKit, you've also taken on the task of creating your own bespoke game engine and tool set.

Given a choice between SceneKit and RealityKit, I recommend not basing a new project on the API that no longer seems to be supported.

Drew Olbrich @drewolbrich.bsky.social · 04/06/2025

RealityKit has been updated every year since it was introduced in 2019. SceneKit and RealityKit both support AR and non-AR rendering. On visionOS, SceneKit is not supported for stereo 3D rendering, and only works in a flat window.

WWDC17 featured a "SceneKit: What's New" session video developer.apple.com/videos/play/... Then, in the seven years that followed, Apple never updated SceneKit or mentioned it at WWDC again. I don't have a source because AFAIK, Apple provided no communication except through silence and inaction.

Nice, thanks for writing this up. fwiw, for 3D, SceneKit was superseded by RealityKit in 2019.

Hey everybody, I've made an important discovery. AIs are fundamentally unable to reason about how to mix Objective-C and Swift code within a Swift package. I'm still working out the details, but on the day of the machine uprising, I believe we'll be able to exploit this weakness and defeat them.

That's great to hear. Maybe MeshResource.Contents was overlooked in the Swift 6 transition and the set of external developer using MeshResource.Contents and adopting Swift 6 last summer and who would actually report the issue as feedback was small.

It really is. Either your eyes are in the front of your head to help you chase down other animals to eat them, or your eyes are on the sides of your head so you’re always on the lookout for the animals that are trying to eat you.

We have nothing to fear from AI until it is able to reason about multiplatform Xcode project Info.plist configuration. Based on my experience this morning, I estimate that this will take another 20 or 30 years.

Meanwhile, I've revised gist.github.com/drewolbrich/... to use MeshResource.generate(from:) instead, which is synchronous. The updated version of the Gist should no longer generate any errors, but unfortunately is not async.
