@property definitions with ARC: strong or retain?

Question

Using Xcode 4.2 and ARC, I notice that the auto-generated code for an NSManagedObject still reads like this for properties:

@property (nonatomic         


        

Answer 1

To answer all three questions in one: retain and strong are synonymous with each other, so both are correct. The documentation states

retain implies __strong ownership

strong implies __strong ownership
