Creating a custom activity indicator in Swift allows you to tailor the appearance and behavior of your loading spinner to fit the style of your app. Here's a step-by-step guide to creating a simple custom activity indicator using UIView Step 1: Create a New Swift File for the Custom Activity Indicator Create a new Swift file and name it RotatingCirclesView.swift . Add the following code to define a custom UIView subclass for your activity indicator: // // RotatingCirclesView.swift // Welcome In // // Created by Praveen Kumar on 05/09/24. // import UIKit class RotatingCirclesView : UIView { let circle1 = UIView ( frame : CGRect ( x : 20 , y : 20 , width : 60 , height : 60 )) let circle2 = UIView ( frame : CGRect ( x : 120 , y : 20 , width : 60 , height : 60 )) let position : [ CGRect ] = [ CGRect ( x : 30 , y : 20 , width : 60 , height : 60 ), CGRect ( x : 60 , y : 15 , width : 70 , height : 70 ), CGRect ( x : 110 , y : 20 , width : 60 , heigh
1. What is Big O Notation, What Time and Space Complexity Answer:- Big O Notation is a mathematical notation describe the limiting behavior of a function when the argument tends towards a particular value or infinity. बिग ओ नोटेशन एक गणितीय संकेतन है जो किसी फ़ंक्शन के सीमित व्यवहार का वर्णन करता है जब तर्क किसी विशेष मान या अनंत की ओर जाता है। "Big O Notation is key in Algorithms and Data Structure, Big O Notation describe the complexity of your code using algebraic terms." "बिग ओ नोटेशन एल्गोरिदम और डेटा संरचना में महत्वपूर्ण है, बिग ओ नोटेशन बीजगणितीय शब्दों का उपयोग करके आपके कोड की जटिलता का वर्णन करता है।" Big O Notation describe the worst-case scenarios with the complexity 1. O(1) :- Constant Complexity -> Execution time does not depend on data size. For Example - 0(1) operations let array = [1, 2, 3, 4, 5, 6] Accessing an element in an array by index. print(array[0]) print(array[2]) Here is an example of an O(1) constant time complexity function i
