Today when I tried to create a new project I quickly noticed that I got an error:
"an internal error occurred. source editor functionality is limited. attempting to restore"
Which is weird, a project that was created literally 5 seconds ago shouldn't have any errors, right?
So I closed it and opened an older project, no errors there.
Next I deleted the new project and recreated it. Still the same error.
I cleaned derived data, restarted Xcode, restarted my mac, even went as far as completely uninstalling Xcode and then reinstalling it, but I still get the same error.
Not only does that error stop me from using auto-completion and other nice editor features, but also from creating outlets for my views
Hopefully someone here has an idea how to fix this.
