SwiftUI @State vs Binding

Question

I am learning iOS Programming with Swift and SwiftUI. I know very little and I am very confuse about the difference between a @State and a Binding<*>

Answer 1

State simple properties like string, integers, and Booleans Belong to a single view - mark as private

Binding complex properties like custom type Sharing data in many views. Required for reference types

EnvironmentObject properties created elsewhere such as shared data App crashes if it is missing.
