I'd like to be clear that the Foundation Models framework and #Playground do support iOS simulators, and I've confirmed that the code snippet provided above works with my following configuration, as shown in the attached screenshot: MacBook Pro with Apple M4 chip. macOS 26.0 Beta (25A5295e), Apple Intelligence is enabled and works. Xcode 26.0 beta 2 (17A5241o) The iOS simulator: iPhone 16 Pro (23A5276e) I can't explain why the error happens on your side though. One common-seen unsupported configuration is macOS 15.x + iOS simulator, which is not your case as you confirmed that you ran macOS 26 Tahoe. You can double check if your configuration has any difference from mine – I am on Beta 2, and your Mac with the M2 chip should work. If the the problem is still there, I’d suggest that you file a feedback report with a sysdiagnose, and share your report ID here. See this post for how to provide actionable feedback for the Foundation Models framework. Best, —— Ziqiao Chen Worldwide Dev
