Support semantic search with Core Spotlight

For the past few days, I've been trying to support semantic search with Core Spotlight, but I haven't found any proper source on the Apple Developer site. In the explanation video, Jennifer mentioned checking the link below, but there was no link provided. If anyone is implementing this feature or has more information, could you please share any insights or resources? TIA

Tried to implement sample code from session 10131. Running on simulator gives me model loading errors:

[Model loading] model loading failed with err -1000 for model path /Users/deszip/Library/Developer/CoreSimulator/Devices/EB928B2D-426F-40DD-A85F-7FF41442C02A/data/Containers/Data/Application/2DC7FE09-4F6E-411F-89CF-E65338EA2101/Library/Spotlight/Resources_V3/Experimental/models/spotlight_l2.mlmodelc and directives path /Users/deszip/Library/Developer/CoreSimulator/Devices/EB928B2D-426F-40DD-A85F-7FF41442C02A/data/Containers/Data/Application/2DC7FE09-4F6E-411F-89CF-E65338EA2101/Library/Spotlight/Resources_V3/Experimental/directives/directives_l2.mdplist

And on device looks like smth wrong with xpc to some helper app:

### qid=2 error Error Domain=NSCocoaErrorDomain Code=4097 "Couldn’t communicate with a helper application." reply:<xpc object>

In general it just does not work :( Any hints or help appreciated.
