iOS Swift - SwiftUI Basics

You want to create a button that changes its title to "Clicked" when tapped. Which code snippet correctly implements this behavior?

let button = UIButton()
button.setTitle("Tap me", for: .normal)
button.addTarget(self, action: #selector(changeTitle), for: .touchUpInside)

@objc func changeTitle() {
    // What goes here?
}

Aself.button.setTitle("Clicked", for: .normal)

Bbutton.setTitle("Clicked", for: .normal)

Cbutton.title = "Clicked"

DchangeTitle.title = "Clicked"

Step-by-Step Solution

Solution:

Step 1: Understand scope of button variable
The button variable is declared outside the method, so inside changeTitle() you must reference it properly, usually as self.button.
Step 2: Use correct method to change title
UIButton's title is changed using setTitle(_:for:) method, not by assigning to a property.
Final Answer:
self.button.setTitle("Clicked", for: .normal) -> Option A
Quick Check:
Use self.button.setTitle to update title [OK]

Quick Trick: Use self.button.setTitle("Clicked", for: .normal) inside action [OK]

Common Mistakes:

Trying to assign title directly
Using button without self when needed
Calling setTitle on wrong object
