Foundation Models (Detected Content Likely to be Unsafe) Error

Thanks @azamsharp! That is almost definitely a bug with the guardrails. Can you file a Feedback report?

• In the Playground Canvas, on the far right of the "Playground has encountered an error" card, you should see a "!" icon that will let you directly file a Feedback bug report.

To help us track down the issue, would you also be willing to share your Siri language setting? That can be found in the Settings app > Apple Intelligence & Siri > Language.

The guardrails have some language-specific behavior, so there's a known issue we're tracking where guardrails are over-triggering for some languages and locales.

Hi @azamsharp, in addition to filing feedback, can you please provide the exact version numbers of macOS Tahoe and Xcode 26, including whether or not they are developer beta versions?

Foundation Models had some guardrail bugs in beta versions that have since been resolved.

Best,

I have the same issue, basically with the same code example

macOS Version 26.0.1 (25A362) Xcode Version 26.0.1 (17A400)

Same issue. I'm using Xcode Version 26.0.1 (17A400) on macOS v26.0.1 (25A362) and I restarted Xcode, turned Apple Intelligence off and then back on, and I got the error from a Playground and a locally built app (FoundationModelsCodeAlong).

I fixed the issue (for now) by restarting my Mac. Then, both the playgrounds and apps

I am working through the Apple Developer Foundations Models Code Along. Last week I successfully completed Chapter 1.6 and got the app to run with Generate Itenerary output. However, this week, I'm now getting a new error and the foundation model is now giving a console error that says "Safety guardrails were triggered. If this is unexpected, please use LanguageModelSession.logFeedbackAttachment(sentiment:issues:desiredOutput:) to export the feedback attachment and file a feedback report at https://feedbackassistant.apple.com."

Rebooting my Mac and doing Build and Run again worked.
