iOS Swift - Animations

Which of the following is the correct syntax to add an implicit animation to a SwiftUI view that animates changes to a Boolean state variable named isOn?

A.animation(isOn, .easeInOut)

B.animation(.easeInOut)

C.animation(easeInOut, value: isOn)

D.animation(.easeInOut, value: isOn)

Step-by-Step Solution

Solution:

Step 1: Recall the correct .animation syntax
The correct syntax uses .animation(animation, value: variable) where animation is a predefined animation like .easeInOut.
Step 2: Match the syntax with the options
.animation(.easeInOut, value: isOn) correctly places .easeInOut first and then value: isOn. Other options have wrong order or missing dot.
Final Answer:
.animation(.easeInOut, value: isOn) -> Option D
Quick Check:
Correct syntax = .animation(animation, value: state) [OK]

Quick Trick: Use .animation(animation, value: stateVariable) format [OK]

Common Mistakes:

Swapping parameters order
Missing dot before animation type
Omitting value label
