Draw a basic data model with images in it. These images are stored in an object called OImage. There are several more objects that contain “images,” so they all have one to many relationships with the OImage object. One example is an OLocation object from an image.
As you can see, OLocation is one-to-many with OImage. Since this is not necessary, there is no inverse relationship to OImage pointing to OLocation. Everything is according to plan.
However, when I create my project, Xcode warns me that there is no inverse relationship:
OLocation.images-to-many : ( )
" " ? -, - ?
