why are you using the xcode UI at all? you can ask claude to run the build via CLI, which will return build errors that claude can read and fix itself until it works. it can even take screenshots from the simulator to debug the app UI.
xcode's new AI using claude is not performing as well as claude code for me. I've tried a couple times and quickly fall back to using vscode with xcode sitting in a window beside. I don't mind the copypaste of warnings and errors since my workflow is less vibe and more directed/iterative.
