114 Pointsreturning a string from a method in a struct
How do I return a string from the "description" method in this struct "Post" of the structures variables? I am trying to do this with "return title + author + tag" under the in the middle of the code.
struct Tag {
let name: String
}
struct Post {
let title: String
let author: String
let tag: Tag
func description() {
return title + author + tag
}
}
let firstPost = Post( title: "hi", author: "hi", tag: Tag(name:"hi"))
let postDescription = firstPost.description

18,216 PointsHi Ryan, There are three mistakes in your code. First, you should specify the return value of the method description, if you do not then it will return void (i.e. return nothing), Second, tag is a Tag object, it is not a String, you cannot add strings with other objects. You may want to use tag.name. Third, when calling the description method, you forgot to type the parenthesis like this: description()
So, the correct code will become like this:
struct Tag {
let name: String
}
struct Post {
let title: String
let author: String
let tag: Tag
func description() -> String
{
return title + author + tag.name
}
}
let firstPost = Post( title: "hi", author: "hi", tag: Tag(name:"hi"))
let postDescription = firstPost.description()
