I am gonna make an app for viewing comics from https://xkcd.com and I am utilizing their API.
In my iOS app I’ve two buttons, subsequent web page and prev web page. I need to click on subsequent to get to the subsequent web page and and so forth.
That is my API:
struct Comedian: Codable {
var month: String
var num: Int
var hyperlink: String
var 12 months: String
var information: String
var safe_title: String
var transcript: String
var alt: String
var img: String
var title: String
var day: String
}
enum ApiError: Error {
case dataIsNil
}
class ApiCall {
var comicNumber = 300
func getComic(completion: @escaping (Outcome<Comedian, Error>) -> ()) {
guard let url = URL(string: "https://xkcd.com/(comicNumber)/data.0.json") else {return}
URLSession.shared.dataTask(with: url) { information, _, error in
if let error = error {
print(error)
completion(.failure(error))
return
}
guard let information = information else {
print("information is nil")
completion(.failure(ApiError.dataIsNil))
return
}
do {
let comedian = attempt JSONDecoder().decode(Comedian.self, from: information)
// print(comedian)
DispatchQueue.principal.async {
completion(.success(comedian))
}
} catch {
print(error)
completion(.failure(error))
}
}
.resume()
}
}
And that is my view
struct ComicContainer: View {
@State var comedian: Comedian?
var physique: some View {
VStack {
NavigationLink(vacation spot: ComicDetailView(), label: {
AsyncImage(url: URL(string: comedian?.img ?? "Picture"))
})
Textual content("Comedian num: (comedian?.num ?? 0)")
.padding()
.onAppear {
ApiCall().getComic{ end in
change consequence {
case .success(let comedian):
self.comedian = comedian
case .failure(let error):
print(error)
}
}
}
.toolbar {
ToolbarItemGroup(placement: .bottomBar) {
CustomButton {
print("prev")
} content material: {
Textual content("Prev")
}
Spacer()
CustomButton {
print("subsequent")
} content material: {
Textual content("Subsequent")
}
}
}
.navigationBarTitle("(comedian?.title ?? "title")")
}
}
}
Does anybody have any tricks to how I can clear up this? I’m fairly new with swift and have been combating this.
