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,...
Getting Started Save, Fetch, Update and Delete Core Data in Swift 5.0
Core Data is NOT an SQLite database. it is a graphical and persistence framework.CURD in swift (Create, Update, Retrieve, Delete)
//MARK: - Save User Info Data
func addData(user_name: String, user_email: String, user_dob: String, imageData: NSData) {
guard let appDelegate = UIApplication.shared.delegate as? AppDelegate else {

let managedContext = appDelegate.persistentContainer.viewContext
let entity = NSEntityDescription.entity(forEntityName: "UserInfo", in: managedContext)!
