5,512 PointsHow do you use string interpolation with a struct?
Hi. I'm stuck on this task even though I completed the whole SWIFT 2.0 track including Object-Oriented SWIFT. How can I use a struct with string interpolation? Can I get a hint please?
struct Tag {
let name: String
func tagName() -> String {
let tagName = "\(name)"
return tagName
}
}
struct Post{
let title: String
let author: String
let tag: Tag
func description() -> String {
let description = "\(title) by \(author). Filed under \(tag)"
return description
}
}
let swift = Tag(name: "Swift")
let firstPost = Post(title: "iOS Development", author: "Apple", tag: swift)
let postDescription = firstPost.description()

why did you wrote the tagName()
method? You can easily get the tag name by calling tag.name
. In your description()
method you try to get the name of a tag by calling just tag
. You should call tag.name
instead.
This is my solution:
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.name)"
}
}
let firstPost = Post(title: "iOS-Development", author: "Moritz", tag: Tag(name: "iOS"))
let postDescription = firstPost.description()
Let me know if you have any further questions about it. :)
