I'm using Xcode 26 Beta 5 and get errors on any generation I try, however harmless, when wrapped in the #Playground macro.
#Playground { let session = LanguageModelSession() let topic = "pandas" let prompt = "Write a safe and respectful story about (topic)." let response = try await session.respond(to: prompt)
Not seeing any issues on simulator or device. Anyone else seeing this or have any ideas?
Thanks for any help!
Version 26.0 beta 5 (17A5295f) macOS 26.0 Beta (25A5316i)
You may be hitting a known issue in Beta 5. This is in our release notes:
In some cases, requests you make to the model erroneously throw a guardrailViolation for all prompts due to model assets not fully downloaded. (156223847) (FB18944619)
Workaround: Stay connected to the internet and try again later.
I've definitely had Xcode open for hours and seeing the same thing. Also, would this be expected as a known issue only for generations in the #Playground macro? Generations in simulator are fine.
Looks like you are using macOS 26 beta 4, not beta 5. I'd recommend upgrading to beta 5 to match your Xcode.
That worked! Thanks!
