Debugging

D ebugging Basic debugging in Swift involves identifying and fixing issues or bugs in your code. Here's a brief guide on how to approach debugging with examples and techniques commonly used in Swift development: 1. Using Print Statements One of the simplest ways to debug is to use print() statements to output variable values or program flow. Example: swift import UIKit class ViewController : UIViewController { var score: Int = 0 override func viewDidLoad () { super .viewDidLoad() // Debugging with print statements print ( "Initial score: \(score) " ) // Prints initial score score = calculateScore() print ( "Updated score: \(score) " ) // Prints updated score } func calculateScore () -> Int { // Debugging inside a function let points = 10 print ( "Points: \(points) " ) // Print points value retur...
