Core Data: Solving Ambiguous Type / Redeclaration of Type

This article provides a solution for resolving compiler errors like 'Invalid redeclaration of Product' or 'Product is ambiguous for type lookup' when creating NSManagedObject subclasses in Core Data with Xcode 8. It explains that the issue stems from Xcode 8's automatic code generation for NSManagedObject subclasses being enabled by default. The tutorial offers step-by-step instructions to turn off auto codegen, set the module to 'Current Product Module', and clear derived data to fix the build errors. It is a technical guide for iOS developers working with Core Data.
