Public var VS var in NSObjectManaged Subclasses

Forums > 100 Days of SwiftUI

When Paul first presents Core Data, he uses public var in the NSObjectManaged Subclasses, but then in his solution to the Friendface - Part2 project he used var instead without public. What's the difference and does it matter? I mean it must matter on some level.

   

By default, unmarked properties have internal access level. The difference between internal and public is that public properties (and methods) are available across module boundaries, while things marked as internal are not.

It's been quite a while since I looked at any of the HWS projects (although I've been thinking I should redo them now that Paul has updated everything) so I'm not sure why he picked one over the other in the particular case you are asking about.

   

Thanks. Can you show an example of using one over the other?
