Is there any instructions for setting up inverse Many-to-Many relationships in Swift on Ray Wenderlich? I found an old video on YouTube, on Beginning Core Data, but for Swift 2, iOS 9, Xcode 7, that was perfect. It showed a situation where there are many devices and many owners, and how you could search back and forth either by item or owner. However, the code is too out of date, so I signed up with RW to get an updated version.
Unfortunately for me, in the updated versions, the content has changed, and the new projects are different. They do not cover how to use the Many-to-Many inverse search in any substantial way. I have gone back and watched the old versions of Beginning Core Data for Swift 5.1, Swift 4 (iOS 12, Xcode 10), Swift 4 (iOS 4, Xcode 9) and Swift 3. None of them cover this topic. I thought it might now be covered in an Intermediate lesson, but the only one i found for Core Data is in Swift 3.
I’m too stupid to make the jump from Swift 2 to Swift 5, and I am hoping there is some module here that can help. If you know of one, that, again, i’m too stupid to find, please let me know.
