message isn's displayed when crash by assertNoFailure

When crash by assertNoFailure, I cannot see the message.

smaple code

View

import SwiftUI

struct ContentView: View {
  @ObservedObject private var viewModel = ContentViewModel()
  var body: some View {
      Button(action: { viewModel.crash() }, label: { Text("button") })
  }
}

ViewModel

import Foundation
import Combine
class ContentViewModel: ObservableObject {
  var cancellables = Set<AnyCancellable>()

  private enum AddOneError: Swift.Error {
    case error
  }

  private func addOnePublisher(_ n: Int) -> AnyPublisher<Int, AddOneError> {
    Deferred {
      Future { (promise) in
        guard n < 10 else {
          promise(.failure(AddOneError.error))
          return
        }
        promise(.success(n + 1))
      }
    }
    .eraseToAnyPublisher()
  }

  func crash() {
    addOnePublisher(10)
      .assertNoFailure("I want to disply this message.")
      .sink { (completion) in
        switch completion {
        case .finished:
          break
        case .failure(let error):
          print(error)
        }
      } receiveValue: { (n) in
        print(n)
      }
      .store(in: &cancellables)
  }

}

when crash

if I use

.catch { error -> AnyPublisher<Int, Never> in fatalError("I can see this message") }

instead of assertNoFailure I can see log

Fatal error: I can see this message

How can I see the prefix of assertNoFailure? And if not, when is it used?

As far as I can tell, the only way to display the message is to use fatalError.
