Another issue others have seen is that the OS Setting "Apple Intelligence" must be turned on. Other requirements are a Silicon Mac and latest MacOS 26. For some regions "Apple Intelligence" is not available. "Apple Intelligence must be turned on before launching Xcode to use coding intelligence features. (152533281)" https://developer.apple.com/forums/thread/844711?answerId=906189022#906189022 lists a workaround

The new UI is for homework and throwaway experiment projects you have to save the project to select the directory. To get a proper project don't select "App" always use "Choose Template"

@cgorkie1 See this for a workaround and please file a feedback https://developer.apple.com/forums/thread/834726?answerId=895664022#895664022

Hi @Amer1go I can't reproduce this the only thing I can think of is to check your system settings and ensure that "Apple Intelligence & Siri" is enabled

To fully utilize local models in Xcode 27 beta 6 you need three things: A MLX model from 🤗Hugging Face (https://huggingface.co/models?library=mlx&sort=trending) An inference server, I'm using oLMX (https://omlx.ai) A tool using agent, I use OpenCode (https://opencode.ai) There is lots of info on how to configure OpenCode to use oLMX IMPORTANT Xcode 27 Beta 5 and later requires that the Agent executable be signed or Xcode crashes. Every time you update OpenCode you will need to resign the new executable Self Sign OpenCode # locate you opencode which opencode # codesign it codesign --force -s - /Users/gdunham/.opencode/bin/opencode # verify it codesign --verify --verbose /Users/gdunham/.opencode/bin/opencode # later update opencode opencode upgrade Multiple Models with OpenCode The way to use multiple models with OpenCode in Xcode 27, is to create a custom agent for each model and use environmental variables to specify the model.

You need to download the new agents in Settings -> Components.

I also submitted a Feedback FB23952965.

I was able to work around this by: Creating a public link in the External Group of Testers. I opened the link on my iPhone and installed the app. Finally I disabled the public link

Also I was cleaning up my screenshots from WWDC and saw this question of yours in a Q&A Is there a way to open the Terminal on the project root folder in Xcode? I have a Behavior in Xcode and a script ~/bin/openterminal.sh #!/bin/bash env | sort > ~/Xcode_behaviors.out echo "XcodeWorkspace = $XcodeWorkspace" >> ~/Xcode_behaviors.out echo "XcodeProject = $XcodeProject" >> ~/Xcode_behaviors.out if [ "$XcodeWorkspace" == "package.xcworkspace" ] then echo "open dir: $XcodeProjectPath/.." >> ~/Xcode_behaviors.out open -a Terminal "$XcodeWorkspacePath/../../.." elif [ -n "$XcodeProject" ] then echo "open dir: $XcodeProjectPath/.." >> ~/Xcode_behaviors.out open -a Terminal "$XcodeProjectPath/.." else echo "open dir: $HOME" >> ~/Xcode_behaviors.out open -a Terminal "$HOME" fi # PROJECT # # XcodeDeveloperApplicationsDirectory=/Applications/Xcode 15.app/Contents/Developer/Applications # XcodeDeveloperDirectory=/Applications/Xcode 15.app/Contents/Developer # XcodeDeveloperPlatformsDirectory=/Applications/Xcode 15.app/Contents/Developer/Platforms # XcodeProject=TestCodeScanner.xcodeproj # XcodeProjectPath=/Users/gdunham/Library/CloudStorage/Dropbox/Development/DDS Experiments/TestCodeScanner/TestCodeScanner.xcodeproj # XcodeWorkspacePath=/Users/gdunham/Library/CloudStorage/Dropbox/Development/DDS Experiments/TestCodeScanner/TestCodeScanner.xcodeproj/project.xcworkspace # PACKAGE # # XcodeDeveloperApplicationsDirectory=/Applications/Xcode 15.app/Contents/Developer/Applications # XcodeDeveloperDirectory=/Applications/Xcode 15.app/Contents/Developer # XcodeDeveloperPlatformsDirectory=/Applications/Xcode 15.app/Contents/Developer/Platforms # XcodeWorkspace=package.xcworkspace # XcodeWorkspacePath=/Users/gdunham/Library/CloudStorage/Dropbox/Development/DDS Swift Packages/DDSUtilities/.swiftpm/xcode/package.xcworkspace

The toolbar button defults to the last used. To select a different provider you need to use the "Coding Assistant" Navigator "New Conversation" Button. To select the Model use you need to change the model setting in "Xcode Settings" -> "Intelligence" -> "Claude Agent" If this is a problem you and every one that reads this should submit a Feedback.

The issue is that you can open an AI Conversation in an Editor Pane using the contex menu but not a source coded file. With out tweaking your Xcode Navigation Settings to use either Destination Chooser or Open in Editor Pane. I file a Feedback FB23258229 on this Here is how to change your Xcode Navigation Settings

I totally missed the inspector. I filed a feedback FB23141979 using the Feedback Assistent App. You should too the more feedback the more likely it will be fixed.
