I'm trying to remove the logic from the view, while keeping the benefits of SwiftUI. Idea 1 works but it makes use of an extra variable than I would want to. Idea 2 gives error: Property wrappers are not yet supported on local properties. What is the best way of making this work? Many thanks.
import Combine
import Foundation
import SwiftUI
// Model
enum Model: String, RawRepresentable {
case foo = "foo"
case bar = "bar"
}
// State
var data1: String = Model.foo.rawValue
class State: ObservableObject {
@Published internal var data2: String = data1
}
// Logic
func logic() {
// Idea 1: OK
//data1 = Model.bar.rawValue
//print(State().data2)
// Idea 2: Error Property wrappers are not yet supported on local properties
@ObservedObject let state = State()
state.data2 = Model.bar.rawValue
print(state.data2)
}
// View
struct bar: View {
@EnvironmentObject private var state: State
internal var body: some View {
logic()
return Text(verbatim: self.state.data2)
}
}
