visionOS, bfloat is not supported on this target

Hi, i'm trying to adapt our project to run on visionOS and faced with problem from the topic while running command:

xcrun --sdk xros metal --target=arm64-apple-xros1.0 input.metal -c -o output.air

The full command output looks like that:

I'm using Xcode 15.2 (15C500b) on MacBook 16 Pro (M1 Pro) and xcrun --sdk xros metal --version gives me this:
