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,...
SOLID Principles in Swift - ( Single Responsibility Principle(SRP), Open/Closed Principle, Liskov Substitution Principle, Interface Segregation, Dependency Inversion)
SOLID Principles in Swift
- Single Responsibility Principle
- Open/Closed Principle
- Liskov Substitution Principle
- Interface Segregation
- Dependency Inversion
S - Single Responsibility Principle(SRP)
Single Responsibility Principle (SRP) is that every class, module, or function in a program should have one responsibility(Task) in a program.
Example:- A Simple Class For multiple Responsibility
class SimpleHandler {
func simpleHandle() {
let data = requestToDataAPI()
let array = parseToResponse(data: data)
saveToDatabase(array: array)
}
private func requestToDataAPI() -> Data {
// Network request and wait the response
return Data()
}
private func parseToResponse(data: Data) -> [String] {
// Parse the network response into array
return []
}
private func saveToDatabase(array: [String]) {
// Save parsed response into database
print(array)
}
}
This Simple class perform multiple Responsibility like first network, second parsing data and last loadData Binding data
Example:- It states that every module or Class should have only one responsibility.
class SrpHandler {
let api: APIHandler
let parse: ParsingData
let datahander: DataHandler
init(api: APIHandler,
parse: ParsingData,
datahander: DataHandler) {
self.api = api
self.parse = parse
self.datahander = datahander
}
func handler(){
let data = api.reqDataToApi()
let array = parse.parseResponse(data: data)
datahander.loadDataUI(array: array)
}
}
// Network request and wait the response
class APIHandler {
func reqDataToApi() -> Data{
return Data()
}
}
// Parse the network response into array
class ParsingData {
func parseResponse(data: Data) -> [String]{
return []
}
}
// Save parsed response into database
class DataHandler {
func loadDataUI(array: [String]){
print(array)
}
}
O - Open/Closed Principle
Open means - Open for extension
closed means - closed for modification.
Open for Extension You should be able to extend or change the behavior of a class without effort. mean If you have to change in an existing class or change the behaviour.
Closed For Modification You must extend a class without changing the implematation
L - Liskov Substitution Principle (LSP)
The Liskov Substitution principle :- A Derived class should be substitutable for its base class without affecting the correctness of the program.
Or
If you have a reference to a base class, you should be able to substitute a derived class without breaking the program.
Example: -
import Foundation
class Rectangle {
var width: Double
var height: Double
init(width: Double, height: Double){
self.width = width
self.height = height
}
func calculateArea()-> Double{
return width * height
}
}
class Square: Rectangle {
override var width: Double {
didSet{
height = width
}
}
override var height: Double{
didSet {
width = height
}
}
init(side: Double){
super.init(width: side, height: side)
}
func printArea(rectangle: Rectangle){
let area = rectangle.calculateArea()
print("Area : \(area)")
}
}
let square = Square(side: 10.0)
printArea(rectangle: square)
