Imagine you have ViewModel which computed property may change from time to time:
import Foundation
class ViewModel: ObservableObject {
private var val = 42;
var compProp: Int {
return val
}
func maybeChange() {
if (Int.random(in: 0..<2) == 1) {
val += 1
???
//heyViewThePropertyIsChanged(nameof(compProp))
}
}
}
How could you force the View:
import SwiftUI
struct ContentView: View {
@StateObject var viewModel: ViewModel
var body: some View {
VStack {
Text("\(viewModel.compProp)").font(.title)
}
.frame(minWidth: 320)
.toolbar {
Button(action: viewModel.maybeChange) {
Label("Maybe", systemImage: "gear.badge.questionmark")
}
}.padding()
}
}
to reflect such a change?
