Appears to be fixed now when using the Simulator 16.0 with iOS 18.5. At least I see http/3 working fine now from the iPhone and iPad in the simulator with my app and also with Safari.

Can anyone explain why Apple requires the terms of use link in the text of the app description on the app store (app metadata)? In the General App Information a checkbox already exists where the developer has to decide between the standard Apple EULA or a custom terms of use and that link is shown in the app store below the text. It doesn't appear to make sense to have the link also inside the text, especially with links inside the description text not being rendered as links. Is that some legal workaround they currently need for reference or archiving or what's the reason for the redundant information inside the description text and the separately shown link below the text?

Still the same here with macOS 15.4.1 and XCode Simulator 16.0 (1042.1) Vision OS 2.4. Workaround of disabling http/3 on the server side still works fine.

I've read above about the issue being related to http/3 and indeed, disabling http/3 on the server side is a workaround. http/2 and older works fine.

Same here and even the builtin Safari.app inside the VisionOS 2.4 of Simulator 16.0 fails.

Works great! Just released my first Vision Pro app to display daily new Mars Rover images in stereo. Currently trying to add HDR as in 2d I can already display them and use that already since 4 month in the app for iOS: areoHDR In case anyone likes to beta test my Vision Pro app, msg me for the testflight link.

Writing HEIF / HEIC images with Linux tools is apparently difficult due to interpretations regarding potential patents on standards used in them in the open source community. I could build an imagemagick which writes HEIC, but didn't manage yet to modify attributes in them. For changing attributes I could only find this so far: https://developer.apple.com/documentation/ImageIO/writing-spatial-photos That tool can be run from the command line, but only on macOS due to the ImageIO library which is not available in the Swift for Linux version.

Same question for me! Currently it only shows the right eye and I like to toggle between right and left for some checks if what I'm planning is actually possible on the device before buying one to develop my app for it.
