Convert HTML text to displayable text in swiftUI [duplicate] - swiftui

Question

I was wondering how can HTML tags be stripped out of JSON from a web url. Do I have to use NSString of something similar.
So I am looking to strip out the html tags that are in the summary value. I looked around abit and it says NSString can be used but I was not sure if that was something that could be implemented into Swift 3. Any Help would be appreciated.
My code:
import UIKit
import Alamofire
struct postinput {
let mainImage : UIImage!
let name : String!
let author : String!
let summary : String!
}
class TableViewController: UITableViewController {
var postsinput = [postinput]()
var mainURL = "https://www.example.com/api"
typealias JSONstandard = [String : AnyObject]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
callAlamo(url: mainURL)
}
func callAlamo(url : String){
Alamofire.request(url).responseJSON(completionHandler: {
response in
self.parseData(JSONData: response.data!)
})
}
func parseData(JSONData : Data) {
do {
var readableJSON = try JSONSerialization.jsonObject(with: JSONData, options: .mutableContainers) as! JSONstandard
// print(readableJSON)
if let posts = readableJSON["posts"] as? [JSONstandard] {
for post in posts {
let title = post["title"] as! String
let author = post["author"] as! String
guard let dic = post["summary"] as? [String: Any], let summary = dic["value"] as? String else {
return
}
print(author)
if let imageUrl = post["image"] as? String {
let mainImageURL = URL(string: imageUrl )
let mainImageData = NSData(contentsOf: mainImageURL!)
let mainImage = UIImage(data: mainImageData as! Data)
postsinput.append(postinput.init(mainImage: mainImage, name: title, author: author, summary: summary))
}
}
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
}
catch {
print(error)
}
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return postsinput.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell")
// cell?.textLabel?.text = titles[indexPath.row]
let mainImageView = cell?.viewWithTag(2) as! UIImageView
mainImageView.image = postsinput[indexPath.row].mainImage
//(cell?.viewWithTag(2) as! UIImageView).image = postsinput[indexPath.row].mainImage
let mainLabel = cell?.viewWithTag(1) as! UILabel
mainLabel.text = postsinput[indexPath.row].name
mainLabel.font = UIFont(name: "Helvetica", size:14)
let autLabel = cell?.viewWithTag(3) as! UILabel
autLabel.text = postsinput[indexPath.row].author
autLabel.font = UIFont(name: "Helvetica", size:12)
let sumLabel = cell?.viewWithTag(4) as! UILabel
sumLabel.text = postsinput[indexPath.row].summary
sumLabel.font = UIFont(name: "Helvetica", size:12)
//(cell?.viewWithTag(3) as! UILabel).text = postsinput[indexPath.row].author
return cell!
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

You can use this code for stripping html tags
From your previous question
guard let dic = post["summary"] as? [String: Any], let summary = dic["value"] as? String else {
return
}
let str = summary.replacingOccurrences(of: "<[^>]+>", with: "", options: .regularExpression, range: nil)
print(str)
Edit
I have checked it and it is working
let summary = "<p>Latin text here</p>"
let str = summary.replacingOccurrences(of: "<[^>]+>", with: "", options: .regularExpression, range: nil)
print(str)
Latin text here
