Distinction in Swift between uppercase “Self” and lowercase “self”

Question

While playing in a Swift playground I noticed that Self, with capital \"S\", is available along with the lowercase self. Is there any difference be

Answer 1

I understand Self as a type name(class name for example) and self as an instance of a class/struct , for example:

struct Person {
     static var documentNumner = "9484930"
     var name: String
     var computedFullName: String {
        return ("\(self.name) with document number: \(Self.documentNumner)")

    }
}

You can't use self with a static property but you can use Self
