Updated for Xcode 12.5
This error happens because you’re trying to use the @ObservedObject
property wrapper on a type that doesn’t conform to the ObservableObject
protocol.
For example, you have a type like this:
class User {
@Published var name = ""
}
And you use it in a view like this:
struct ContentView: View {
@ObservedObject var user: User
var body: some View {
Text(user.name)
}
}
To fix the problem, simply add the ObservableObject
conformance to your type, like this:
class User: ObservableObject {
@Published var name = ""
}
