Creating an AI-powered mobile app involves integrating artificial intelligence (AI) technologies to solve specific problems or provide unique features. Here's an overview of how to approach building an AI-powered mobile app: Key Steps to Build an AI-Powered Mobile App 1. Define the App's Purpose and Use Case Identify the problem your app will solve or the value it will offer. Examples of AI use cases in mobile apps: Chatbots (e.g., virtual assistants like Siri) Image Recognition (e.g., object detection, face recognition) Speech Recognition (e.g., voice commands, transcription) Recommendation Systems (e.g., personalized content or product recommendations) Predictive Analysis (e.g., health tracking, financial forecasting) Natural Language Processing (NLP) (e.g., sentiment analysis, language translation) 2. Choose an AI Technology or Framework Select the appropriate AI technologies or frameworks based on your use case: Machine Learning : Core frameworks: TensorFlow, PyTorch,...
A Simple XML Parsing Example in ios with Swift 4.0.
ASMX - SOAP-XML(Simple Object Access Protocol - Extensible Markup Language)
SOAP - Simple Object Access Protocol itis a xml-based messaging protocol for exchanging information among computer
"ASMX provide the ability to build service that send message using the SOAP"
"XML stands for Extensible Markup Language. XML is a markup language much like HTML. XML was designed to store and transport data. XML was designed to be self-descriptive."
its defines a set of rules for encoding documents in a format human-readable and machine-readable.
In this tutorial parse xml web service(apple rss news - https://developer.apple.com/news/rss/news.rss) using a XMLParser object. The results of the parse the data in a tableView in UITableViewController. This tutorial is made with Xcode 10 and built for iOS 12.
Create New Project Xcode a new Single View App
Enter Project Name, Team name, Organization name, or identifier and select language swift.
Now design TableView, Cell in UITableViewController
1. First Create a XMLParser Class - // XMLParser.swift
in struct declare properties of object
2. Then Create TableView Cell Properties where are to display data. - NewsTableCell.swift
ASMX - SOAP-XML(Simple Object Access Protocol - Extensible Markup Language)
SOAP - Simple Object Access Protocol itis a xml-based messaging protocol for exchanging information among computer
"ASMX provide the ability to build service that send message using the SOAP"
- SOAP is communication via internet
- SOAP can extend HTTP for XML messaging
- Data transfer for web service

Create New Project Xcode a new Single View App
Enter Project Name, Team name, Organization name, or identifier and select language swift.
Now design TableView, Cell in UITableViewController
1. First Create a XMLParser Class - // XMLParser.swift
in struct declare properties of object
import Foundation
import UIKit
struct RSSItem {
var title: String
var description: String
var pubDate: String
}
// download xml from a server
// parse xml to Foundation object
// call back
class FeedParser: NSObject, XMLParserDelegate {
private var rssItem: [RSSItem] = []
private var currentElement = ""
private var currentTitle = ""
{
didSet{
currentTitle = currentTitle.trimmingCharacters(in: CharacterSet.whitespacesAndNewlines)
}
}
private var currentDescription = "" {
didSet{
currentDescription = currentDescription.trimmingCharacters(in: CharacterSet.whitespacesAndNewlines)
}
}
private var currentPubDate = "" {
didSet{
currentPubDate = currentPubDate.trimmingCharacters(in: CharacterSet.whitespacesAndNewlines)
}
}
private var parserCompletionHandeler: (([RSSItem])-> Void)?
// Download XML
func parseFeed(url: String, completionHandler: (([RSSItem])-> Void)?){
self.parserCompletionHandeler = completionHandler
let request = URLRequest(url: URL(string: url)!)
let urlSession = URLSession.shared
let task = urlSession.dataTask(with: request) { (data, response, error) in
guard let data = data else{
if let error = error {
print(error.localizedDescription)
}
return
}
// parse our xml data
let parser = XMLParser(data: data)
parser.delegate = self
parser.parse()
}
task.resume()
}
// XML Parser Delegate
func parser(_ parser: XMLParser, didStartElement elementName: String, namespaceURI: String?, qualifiedName qName: String?, attributes attributeDict: [String : String] = [:]) {
currentElement = elementName
if currentElement == "item"{
currentTitle = ""
currentDescription = ""
currentPubDate = ""
}
}
func parser(_ parser: XMLParser, foundCharacters string: String) {
switch currentElement {
case "title": currentTitle += string
case "description": currentDescription += string
case "pubDate": currentPubDate += string
default: break
}
}
func parser(_ parser: XMLParser, didEndElement elementName: String, namespaceURI: String?, qualifiedName qName: String?) {
if elementName == "item" {
let rssItem = RSSItem(title: currentTitle, description: currentDescription, pubDate: currentPubDate)
self.rssItem.append(rssItem)
}
}
func parserDidEndDocument(_ parser: XMLParser) {
parserCompletionHandeler?(rssItem)
}
func parser(_ parser: XMLParser, parseErrorOccurred parseError: Error) {
print(parseError.localizedDescription )
}
}
2. Then Create TableView Cell Properties where are to display data. - NewsTableCell.swift
import Foundation
import UIKit
enum CellState {
case expanded
case collapsed
}
class NewsTableCell: UITableViewCell {
@IBOutlet weak var titleLabel: UILabel!
@IBOutlet weak var descriptionLabel: UILabel!{
didSet{
descriptionLabel.numberOfLines = 3
}
}
@IBOutlet weak var dateLabel: UILabel!
var item: RSSItem! {
didSet {
titleLabel.text = item.title
descriptionLabel.text = item.description
dateLabel.text = item.pubDate
}
}
}
3. Fatch Data UITableViewController TableView. // NewsTableViewController.swift
import Foundation
import UIKit
class NewsTableViewController: UITableViewController {
private var rssItems: [RSSItem]?
private var cellState: [CellState]?
override func viewDidLoad() {
super.viewDidLoad()
tableView.estimatedRowHeight = 155.0
tableView.rowHeight = UITableView.automaticDimension
fetchData()
}
private func fetchData(){
let feedparser = FeedParser()
feedparser.parseFeed(url: "https://developer.apple.com/news/rss/news.rss") { (rssItems) in
self.rssItems = rssItems
self.cellState = Array(repeating: .collapsed, count: rssItems.count)
OperationQueue.main.addOperation {
self.tableView.reloadSections(IndexSet(integer: 0), with: .left)
}
}
}
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
guard let rssItems = rssItems else {
return 0
}
return rssItems.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! NewsTableCell
if let item = rssItems?[indexPath.row]{
cell.item = item
cell.selectionStyle = .none
if let cellState = cellState{
cell.descriptionLabel.numberOfLines = (cellState[indexPath.row] == .expanded) ? 0 : 4
}
}
return cell
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath, animated: true)
let cell = tableView.cellForRow(at: indexPath) as! NewsTableCell
tableView.beginUpdates()
cell.descriptionLabel.numberOfLines = (cell.descriptionLabel.numberOfLines == 0) ? 3 : 0
cellState?[indexPath.row] = (cell.descriptionLabel.numberOfLines == 0) ? .expanded: .collapsed
tableView.endUpdates()
}
}
Finally Output - here parse data with XMLParser
