This SwiftUI application demonstrates how to initialise an ObservableObject as a StateObject in a View's init method.
Let's say you have an ObservableObject named ContentViewModel and you have declared it as a StateObject in your View, as follows:
struct ContentView: View {
@StateObject var viewModel: ContentViewModel
}Naturally, you will try and initialise viewModel in ContentView's init method as follows:
init(someParam: SomeType) {
viewModel = ContentViewModel(someParam: someParam)
}When you try this, you'll get the following compilation error:
Cannot assign to property: 'viewModel' is a get-only property
Fortunately, there's a workaround. See the ContentView.swift file in this project for the workaround.
