I am afraid of doing something I don't understand and end up breaking my code further. Does anyone know how to fix this issue? Should I do ahead and delete the direction? To the best of my knowledge the problem arose out of the blue.

I ran into the same problem today. Simply deleting /Users/myname/Library/Developer/Xcode/ DerivedData/projectname-csxwagvbpfvfsmbgswcukqirbmgg/ should solve your problem. You may also need to exit xcode and restart it.
