2,592 PointsSeems to work in Xcode. Not sure what I'm missing?
Here is the challenge:
Challenge Task 2 of 2
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
When submitting my code for this challenge, it tells me to make sure I am following the instructions and then gives me a hint to "Use string interpolation." I'm not sure what I'm missing here? In Xcode it seems to work.
struct Tag {
let name: String
}
struct Post {
var title: String
var author: String
var tag: Tag
func description() -> String {
return "\(title), by \(author). Filed under \(tag)"
}
}
let firstPost = Post(title: "Samson", author: "Me", tag: Tag(name: "Basement"))
let postDescription = firstPost.description()
struct Tag {
let name: String
}
struct Post {
var title: String
var author: String
var tag: Tag
func description() -> String {
return "\(title), by \(author). Filed under \(tag)"
}
}
let firstPost = Post(title: "Samson", author: "Me", tag: Tag(name: "Basement"))
let postDescription = firstPost.description()

You are very close, I believe you would have figured it out eventually
struct Tag {
let name: String
}
struct Post {
var title: String
var author: String
var tag: Tag
//You need to remove comma after title to match instructions
//Also need to put .name after tag to match struct created
//I have implemented below in your code
func description() -> String {
return "\(title) by \(author). Filed under \(tag.name)"
}
}
let firstPost = Post(title: "Samson", author: "Me", tag: Tag(name: "Basement"))
let postDescription = firstPost.description()
