Welcome to the community.
I have move your post to its own thread since your question is not related to the original question that was asked some time ago.
The challenge 8 says, in part:
- Declare 4 properties called make , model , year and details
and then later on says
- Make all 4 properties have the private access level
which means that by doing so means they are not visible outside of the struct.
In simple terms it means adding the key word
private in front of the declaration.
For example if you have
let make: String = "Toyota"
let..... like this:
private let make: String = "Toyota"
The challenge 7 solution is in the Resources folder which is accessible from the Introduction Module of the course by tapping on the heading "Resources’ which opens up a DropBox folder which has a folder foe each lesson. Drill down on those folders and you will find what you need.
