For those still having trouble installing the runtime to UE5.3 this video has clear step by step instructions. From the instruction video provided by Esoteric I was having problem understanding where to paste the cpp folder for windows. Instructions there are not clear. Hope this helps.
Thanks for looking at it. I hope you get there soon, I know a lot of folks are holding out for this.
I think so too, and I'd love to do that, but it's currently impossible due to limitations of GDExtensions.
As it stands, GDExtensions is not ready for prime time in our case. I've been in discussions with the core team about it, but we have not made any progress on it yet.
This has now been fixed. The MoltenVK.xcframework is now shipped inside the iOS export template.
Sigh, the build system keeps on giving. Sorry for that! I've opened an issue here and will try to resolve this asap.
Yeah, it totally doesn't stress me out 
Yes, there's a plan for going GDExtensions for Godot 4.x going forward. However, this is currently blocked by GDExtensions not exposing all APIs we need, and time. I have not yet figured out the concrete APIs that are missing since I haven't started the "port" yet. I'll report it to the GDExtensions maintainers in the hopes they'll add them.
I've finally figured this out. It's an a bug in Godot 4.1.1-stable, which doesn't work with the latest MoltenVK SDK on macOS. We are always using the latest SDK, while official Godot binaries use a very old SDK version.
New binaries are currently build on our end. They should be ready in 2-3 hours from now. Please redownload the editor from our site and try again later.
