Why isn't my text being added to my label? - json

Question

Revised post: So the code posted below is my stuct
struct AnimeJsonStuff: Decodable {
let data: [AnimeDataArray]
}
struct AnimeLinks: Codable {
var selfStr : String?
private enum CodingKeys : String, CodingKey {
case selfStr = "self"
}
}
struct AnimeAttributes: Codable {
var createdAt : String?
var slug : String?
private enum CodingKeys : String, CodingKey {
case createdAt = "createdAt"
case slug = "slug"
}
}
struct AnimeRelationships: Codable {
var links : AnimeRelationshipsLinks?
private enum CodingKeys : String, CodingKey {
case links = "links"
}
}
struct AnimeRelationshipsLinks: Codable {
var selfStr : String?
var related : String?
private enum CodingKeys : String, CodingKey {
case selfStr = "self"
case related = "related"
}
}
struct AnimeDataArray: Codable {
let id: String?
let type: String?
let links: AnimeLinks?
let attributes: AnimeAttributes?
let relationships: [String: AnimeRelationships]?
private enum CodingKeys: String, CodingKey {
case id = "id"
case type = "type"
case links = "links"
case attributes = "attributes"
case relationships = "relationships"
}
}
This code is my function for parsing data:
func jsonDecoding() {
let jsonUrlString = "https://kitsu.io/api/edge/anime"
guard let url = URL(string: jsonUrlString) else {return}
URLSession.shared.dataTask(with: url) { (data, response, err) in
guard let data = data else {return}
do {
let animeJsonStuff = try JSONDecoder().decode(AnimeJsonStuff.self, from: data)
for anime in animeJsonStuff.data {
// print(anime.id)
// print(anime.type)
// print(anime.links?.selfStr)
let animeName = anime.attributes?.slug
print(animeName)
DispatchQueue.main.async {
self.nameLabel.text = animeName
}
for (key, value) in anime.relationships! {
// print(key)
// print(value.links?.selfStr)
// print(value.links?.related)
}
}
} catch let jsonErr {
print("Error serializing json", jsonErr)
}
}.resume()
}
This is what the console prints out:
Optional("cowboy-bebop")
Optional("cowboy-bebop-tengoku-no-tobira")
Optional("trigun")
Optional("witch-hunter-robin")
Optional("beet-the-vandel-buster")
Optional("eyeshield-21")
Optional("honey-and-clover")
Optional("hungry-heart-wild-striker")
Optional("initial-d-fourth-stage")
Optional("monster")
Optional("cowboy-bebop")
Optional("cowboy-bebop-tengoku-no-tobira")
Optional("trigun")
Optional("witch-hunter-robin")
Optional("beet-the-vandel-buster")
Optional("eyeshield-21")
Optional("honey-and-clover")
Optional("hungry-heart-wild-striker")
Optional("initial-d-fourth-stage")
Optional("monster")
Optional("cowboy-bebop")
Optional("cowboy-bebop-tengoku-no-tobira")
Optional("trigun")
Optional("witch-hunter-robin")
Optional("beet-the-vandel-buster")
Optional("eyeshield-21")
Optional("honey-and-clover")
Optional("hungry-heart-wild-striker")
Optional("initial-d-fourth-stage")
Optional("monster")
It now displays the text but it only displays the last optional called monster and not all the other ones when I have three cells. It only displays monster in each cell.
It should be
1st cell: Cowboy-bebpop
2nd cell: cowboy-bebop-tengoku-no-tobira
3rd cell: trigun
and etc

I can't see where do you set post variable.
Where you put nambeLabel into Controller's view hierarchy?
And maybe you should set nameLabel.text in main thread:
DispatchQueue.main.async {
self.nameLabel.attributedText = attributedText
}
