Xcode is giving me this warning
Skipping duplicate build file in Compile Sources build phase
and a path to my entity class declaration file (for CoreData)
then (in target 'myAppName')
in my XCDataModelD - when i select the entity , i choosed for codegen -> Catergory/Extension
then i created a Class with the same name as my entity.
the warning was not there in the beginning and it was working, then
2 things might have helped create this problem
1- because i had error in my code with entity :-) i tried the menu Editor -> Create NSManagedObject Subclass...
then i decide to delete both of those generated files
2- stll trying to resolve the other problem, I think i have might drag the class from my other project once and it did not work, dragged it again, then it showed up , look at it, and delete it from xcode
but in the finder, when i look in my project,there is only one file for this class ?
i did the Product -> Clean Build Folder
(both without and with ALT key - but i think ALT is not necessary anymore)
