NSPredicate getting error with CoreData -Swift

Question

I can't find whats wrong in syntax . I cross check with apple documentation as well.

        let predicate = NSPredicate(format: "imageID = %@", imgID);

Answer 1

You define ImgID as Double , but the predicate format uses the specifier for an object %@ . So, you should either be passing an NSNumber or using %f in the format.

If the ImgID is actually a double then you may have some issue getting an exact match. In this case you should either convert the id to a different data type, or range check (using < and >).
