While my swift project was running, it suddenly started giving an error and is not being built. In the log records, there is an error called Illegal Configuration
in .storyboard
file, but when I go into my files, no error appears. I just get this error while building.
It seems that in the storyboard you are trying to make an outlet from eg a view controller to eg a prototype cell in a table view or collection view. That is indeed illegal, as it is meaningless. Don't do that.
