Issue Description:

Create an Xcode SwiftUI iOS app project, paste this into ContentView.swift:

import SwiftUI

struct User: Identifiable {
    let id = UUID()
    var name: String
    var isContacted = false
}

final class Model: ObservableObject {
    @Published var users: [User]

    init(_ users: [User]) {
        self.users = users
    }
}

struct ContentView: View {
    @EnvironmentObject private var model: Model

    var body: some View {
        List($model.users, rowContent: itemView($user:))    // <=== !!! this cause preview to crash
        // this works:
        List($model.users) { $user in
            itemView($user: $user)
        }
    }

    func itemView(@Binding user: User) -> some View {
        EmptyView()
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        let data = [
            User(name: "Larry"),
            User(name: "Curly"),
            User(name: "Moe")
        ]
        ContentView()
            .environmentObject(Model(data))
    }
}

Could you attach a crash log?
