Not the OP, but I’ve had success starting with a blank app created by Xcode with the appropriate language/frameworks (ie something that will already run but does nothing). You then ask Claude to start from that point.

The only issue I’ve had is sometimes Xcode not ‘seeing’ new files that Claude has created along the way, and needing to add these manually into the Xcode project. (A Google around suggests this shouldn’t happen if you create the project in the right way, and yet it still sometimes does.)
