CSUserQuery Generating Model Load Failure - No Results

I'm trying CoreSpotlight on the 18b1 seed on iOS and after submitting my query, I'm getting multiple errors about what looks like missing models:

[Model loading] model loading failed with err -1000 for model path /Users/hunter/Library/Developer/CoreSimulator/Devices/0AF4F46E-5510-4458-B61C-F8A153155809/data/Containers/Data/Application/1D8580C0-AC80-4949-9FDA-31DB463BDA5C/Library/Spotlight/Resources_V3/Default/models/spotlight_l2.mlmodelc and directives path /Users/hunter/Library/Developer/CoreSimulator/Devices/0AF4F46E-5510-4458-B61C-F8A153155809/data/Containers/Data/Application/1D8580C0-AC80-4949-9FDA-31DB463BDA5C/Library/Spotlight/Resources_V3/Default/directives/directives_l2.mdplist

I am calling CSUserQuery.prepare() but that doesn't seem to make a difference.

Is there more to this than what is on this page? https://developer.apple.com/documentation/corespotlight/building-a-search-interface-for-your-app?changes=latest_minor

Still seeing this with seed 2. Anyone got this to work?

Same with seed 3.
