3,833 PointsSwift Recap Part 1 Task 2 of 2
Add an instance method to Post. Name it description , it takes no parameters and returns a string that describes the post instance. For example, given a title: “iOS Development”, author: “Apple” and a yag named “swift” —> “iOSDevelopment by Apple. Filed by swift”
Once instance method is created, call it on the firstPost instance and assign the result to a constant named postDescption.
struct Tag {
let name: String
}
let someTag = Tag(name: "swift")
struct Post {
let title: String
let author: String
let tag: Tag
func description() -> String {
return "\(title) by \(author). Filed under \(tag)"
}
}
let firstPost = Post(title: "iOS Development", author: "Apple", tag: someTag )
let postDescription = firstPost.description()

func description() -> String { return "(title) by (author) filed under (tag.name)" }
let postDescription = firstPost.description()

3,833 Points@EdwardLaurenson I thought that you had to use "()" notation for string interpolation? Why is yours missing a \ in front of the ()? But thanks for the help!
