Thank you for responding! metadata.json from the .fmadapter package: { "adapterIdentifier": "fmadapter-foundation-lab-9799725", "author": "Foundation Lab", "baseModelSignature": "9799725ff8e851184037110b422d891ad3b92ec1", "creatorDefined": {}, "description": "Tool adapter.", "license": "", "loraRank": 32, "speculativeDecodingDraftTokenCount": 5 } Code used to load the adapter: // From test-adapter-minimal.swift:39 let adapter = try SystemLanguageModel.Adapter(fileURL: adapterURL) // Also tried the name-based initializer: adapter = try await SystemLanguageModel.Adapter(name: adapterName) Please help make progress here. Thank you!

BTW, I do see a popup but that message in the popup is misleading because i have verified that i am using Xcode Beta 4, not Beta 3 or lower, this is the popup i see, “/Applications/Xcode-beta.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin” Needs to Be Updated. This app needs an update in order to work with the latest Apple Intelligence models. Some features may not work as expected.

Thank you. I am running this in MacOS Beta 4, in sandbox. Filed FB19237327 The Feedback tool didn't even have Beta 4 build in the dropdown.

Hello! thanks for the follow up. i confirmed that it still doesn't work with the renamed adapter file. I am using the APIs exactly as documented, ✅ init(fileURL:) - Direct file URL loading ✅ init(name:) - Name-based loading the problem persists. Let me know if you need any more data. for the time being. i am working around the issue but adapter has to be working for me to make real progress. Thank you.

Thank you, @Frameworks Engineer. I got your comment above. I take it that i won't work still until the signature issue is resolved. On that note, I uploaded the fmadapter as you asked to the feedback. Please take a look. Thank you!

it worked! thank you for the follow-ups and unblocking me!
