Sample core data project to reproduce a scenario that dupes a NSManagedObject without specifically creating a new one.
To reproduce the issue, tap the button multiple times and you'll see that the number of objects increase even though no new object is created.
For example:
CDTest[15510:761956] Result Count [1]
CDTest[15510:761956] Obj Name [Name2]
CDTest[15510:761956] -----
CDTest[15510:761956] SAVED
CDTest[15510:761956] Result Count [1]
CDTest[15510:761956] Obj Name [Name2]
CDTest[15510:761956] -----
CDTest[15510:761956] SAVED
CDTest[15510:761956] Result Count [2]
CDTest[15510:761956] Obj Name [Name2]
CDTest[15510:761956] Obj Name [Name2]
CDTest[15510:761956] -----
