Apple Vision Pro Archive Error

Issue Description:

While trying to archive my project, I encountered some auto-linking library errors. The specific error messages are as follows:

ld: warning: Could not find or use auto-linked library 'swiftCxx': library 'swiftCxx' not found
ld: warning: Could not find or use auto-linked library 'swiftCxxStdlib': library 'swiftCxxStdlib' not found
ld: warning: Could not find or use auto-linked framework 'CoreAudioTypes': framework 'CoreAudioTypes' not found

Environment Information:

  • UnrealEditor version: 5.4.4-0+UE5 from source code
  • Xcode version: 15.2
  • Target platform: VisionOS

Solutions I’ve tried:

  1. Generate Xcode project **.xcworkspace and added LinkBinaryWithLibraries compilation

However, the issue persists. I’m unsure whether it’s caused by missing libraries or a configuration problem in UnrealEditor/Xcode. How can I fix this? Any help would be greatly appreciated!

How did you fix this issue?

I have the same issue. I was wondering if someone figured it out.
EDIT: The link error was unrelated to the ld: warning: Could not find or use auto-linked library 'swiftCxx': library 'swiftCxx' not found warnings.
There were other libs that weren’t linked (in our case core haptics and cloudkit) that were the true source of the problem.

Hi,

This issue seems to be caused by trying to use functions that are no longer available in Apple Vision Pro 2.0, which leads to link errors.

You can try setting
#define SUPPORTS_APPLE_VISION_1_0 1
to
#define SUPPORTS_APPLE_VISION_1_0 0
in
“Engine/Plugins/Experimental/AppleVision/Source/AppleVision/Public/AppleVisionAvailability.h”

and see if that helps.
