How to fix “Fatal error: No ObservableObject of type SomeType found”
Updated for Xcode 12.5
When you’re using environment objects, SwiftUI automatically connects your properties by scanning the environment for matching types. So, if you have an environment property of type User, SwiftUI expects to find an instance of that class in the environment before it is used.
This error occurs because no matching object could be found, which is usually a result of you forgetting to put it into the environment, or putting it into the wrong environment. Remember, you can have multiple environments active in your SwiftUI app: you might have individual environments for each of the tabs in a TabView for example.
To fix the problem, make sure the view that causes the crash has the correct environment set, like this:
YourView().environmentObject(yourEnvironmentObject)
