Hi All,
Please look at this video. https://teamtreehouse.com/library/swift-enums-and-structs/enums/enum-members-and-raw-values
Video playback from 5:50 to 6:10. I cannot understand what it means creating an instance of a day. Watched atleast 100 times. Can some one explain this in baby steps please.
Thanks - Srini

2,206 PointsThink of the Day enum as a blueprint: It has all the specifications of the enum. When you create an instance of Day, it basically means you are using your definition of the Day enum to create an object that will have all the specifications defined in your enum.
One example would be if you had a blueprint of a house, and then built a house with all the specifications from the blueprint. You can still call the blueprint "House", but when you actually build, aka "create" a house, you are creating an instance of the blueprint.
I believe saying "an instance of [something]" is very much used when you are talking about Object-Oriented programming.
Hope it helps!
