This course was created for Core Data targeted iOS 10 and 11.  Unlike when iOS 10 was introduced, this time around there has been no significant changes moving from iOS 10 to 11.  Having said that the Core Data skill that you learnt under iOS 10 will still be applicable for project targeting iOS 11.  

However if your project is dealing with older version of Core Data in iOS 9 or prior, and you intend to learn the previous version, my other course Mastering iOS Core Data with Swift is the course you want.
