For things like linters, formatting tools, and more: We need a good way to inject into the Xcode UI. Can I create a Warning or Error in the buffer/Issue Navigator? Is there an example of how to mark lines/columns with a message/error/warning? Get the current file path or URL object? How can I place a view onto the Xcode source canvas? Like a popover or interactive window.

Hi, I'm working on an Xcode Source Editor Extension. Currently, I have App Sandbox enabled and everything works as expected. I have some features I'd like to add that would require me to disable the App Sandbox and release the extension and containing app outside of the App Store. However, whenever I remove the App Sandbox capability from my project and re-run the extension, I can no longer see my extension appear in the Editor menu - it's just gone. My question is - are Xcode Source Editor Extensions only limited to sandboxed environments or can they operate out of the sandbox? If so, how come I don't see it in Xcode 15?

I want to build an Xcode Source Code Editor extension that triggers an XPC service shows a gui that can handle user interactions Is it possible in any way ? what are the alternatives to display the UI and allow the user to interact on it ?

Hi all, i am setting up my MacBook Pro and cant install Xcode. I downloaded it through the app store. On click it starts up and asks me what platform I would like to develop for. (The window where you have to select When continue is clicked it asks for admin permissions then quits and starts the process over again. I tried running this /Applications/Xcode.app/Contents/MacOS/Xcode -installComponents in the CMD and this opens the same window but still doesnt run but now i get an error when it closes Xcode[837:10271] [MT] IDEFirstLaunch: Cannot continue without relaunching because of already-loaded bundles: [NSBundle </Library/Apple/System/Library/PrivateFrameworks/MobileDevice.framework> (loaded)] Specs: MacBook Pro M1 Pro macOS 14.1
