I just want to fetch data from my website which is wordpress, and put my posts in to my tableview. I was searching but couldn't find a proper answer. Please at least me tell me where to begin with

Answer 1

You need to use awesome new API of WordPress called WP REST API, which will give you all data you need in JSON format. Have a look at this url to get started:
http://v2.wp-api.org/
Use this official plugin in your WordPress site:
https://wordpress.org/plugins/rest-api/
Update: You do not need to install above plugin as it has been merged into WordPress core from v4.4 to onwards.

Answer 2

At first, you should define models for parsing the JSON response, for example, as below.
import Foundation
struct Title: Decodable {
let rendered: String
}
struct Content: Decodable {
let rendered: String
}
struct WPFeaturedMedia: Decodable {
let sourceURLString: String
var url: URL? {
.init(string: sourceURLString)
}
enum CodingKeys: String, CodingKey {
case sourceURLString = "source_url"
}
}
struct Embedded: Decodable {
let medias: [WPFeaturedMedia]?
enum CodingKeys: String, CodingKey {
case medias = "wp:featuredmedia"
}
}
struct PostHeader: Decodable, Identifiable {
let id: Int
let date: Date
let title: Title
let embedded: Embedded
enum CodingKeys: String, CodingKey {
case date = "date"
case title = "title"
case embedded = "_embedded"
case id = "id"
}
}
struct Post: Decodable, Identifiable {
let id: Int
let date: Date
let title: Title
let content: Content
let embedded: Embedded
enum CodingKeys: String, CodingKey {
case date = "date"
case title = "title"
case content = "content"
case embedded = "_embedded"
case id = "id"
}
}
You can easily fetch posts using Combine.
import Combine
import SwiftUI
final class ViewModel: ObservableObject {
#Published var postHeaders: [PostHeader] = []
#Published var error: Error?
private var cancellable: AnyCancellable?
init() {
let url = URL(string: "https://PUT_YOUR_HOST_HERE/wp-json/wp/v2/posts?_fields=id,date,title,_links,_embedded&_embed”)!
cancellable = URLSession.shared.dataTaskPublisher(for: url)
.map { $0.data }
.decode(type: [PostHeader].self, decoder: JSONDecoder())
.receive(on: DispatchQueue.main)
.sink(
receiveCompletion: { completion in
switch completion {
case .failure(let error):
self.error = error
case .finished:
break
}
},
receiveValue: { posts in
self.postHeaders = posts
}
)
}
}
