We learned about instance methods before. For this task, add an instance method to Post.
Name the method 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 tag named "swift", the description would read as follows"
"iOSDevelopment by Apple. Filed under swift"
Once you have an instance method, call it on the firstPost instance and assign the result to a constant named postDescription Bummer! Make sure the implementation of description matches the directions. Hint: Use string interpolation!
struct Tag {
let name: String
}
struct Post {
let title: String
let author: String
let tag: Tag
func description() -> String{
return "\(title) by \(author). Filed under \(tag)"
}
}
let tagtag = Tag(name: "n")
let firstPost = Post(title: "t", author: "a", tag: tagtag )
let postDescription: String = firstPost.description()
