App was initially placed in 2011. Hence, several problems with deprecations made it outdated for IOS 10, including creating the core data stack using the documented technique of the time. I am rewriting the app using Swift and NSPersistentContainer. One thing I have difficulty with is producing a “DataController” class, as described in Core Data Programming Guide section Initializing the Core Data Stack. My problem is that I cannot visualize what the completed class should look like!
Something else about the app: the user can provide more than one file, each of which the app transforms to a separate ‘filename.sqlite’ persistent store for the single managed object model. The user selects among the various transformed filenames to present the differently produced information in a tableview. This was relatively straightforward to do in the initial implementation in OBJC and the “old” core data.
It would be greatly appreciated if someone would show an example of a completed DataController class (I have yet to get past compiler errors in my attempts during the past weeks).
