I've had problems before with the Refactor…
menu getting grayed out, but now it's disappeared entirely in one of my projects.
What I've tried so far:
- Quit Xcode + kill DerivedData + clean build + let indexing finish.
- Quit Xcode + remove com.apple.dt.* and com.apple.preferences.extensions.XcodeSourceEditor.plist
So far, nothing. Very much hoping this can be fixed without having to completely reinstall Xcode from scratch (again).
