SwiftUI Components & Extension that saves iOSDev time. | |
### UIKit is **EVENT-Driven** framework - We could reference each view in the hierarchy, update its appearance when the view is loaded or as a reaction on an event. | |
### SwiftUI is **Declarative, State Driven** framework - We cannot reference any view in the hierarchy, neither can we directly mutate a view as a reaction to an event. | |
Instead, we mutate the state bound to the view. Delegates, target-actions, responder chain, KVO .. replaced with Closures & bindings. |

@State var heightCalculated = 0.0
var body: some View {
ScrollView {
ForEach(0..<10) { i in

}
.background(
GeometryReader { proxy in
Color.clear.onAppear {
heightCalculated = proxy.size.height
debugPrint(proxy.size.height)
}
}
)
}
.frame(height: heightCalculated)
}
