“Declarative” is one of Swift UI’s four core principles.
Aside from taking for granted that declarative is just “better” than whatever else, how about a visual to understand the declarative way of thinking?
Imagine yourself in a restaurant (sit-down or fast food, whichever).
When you want a burger, which best describes what you do?
Saying what you want (aka, being “declarative”) is what the most probable thing you’d do in a restaurant.
That’s exactly the recipe you use when you’re working with SwiftUI.
