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

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!

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. 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.

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 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!
