SwiftUI navigationBarTitle-displayMode:.inline-崩溃 [英] SwiftUI navigationBarTitle - displayMode: .inline - Crash

问题描述

我对SwiftUI有问题.我正在创建一个带有导航栏的列表，并且我想将导航栏模式设置为内联，但我不希望它过大(默认情况下).但是，当我将导航栏标题模式设置为嵌入式时，应用程序崩溃.

I have a problem with SwiftUI. I am creating a list with a navigation bar, and I want to set navigation bar mode to inline, I don't want it to be large which is by default. But when I set navigation bar title mode to inline, the app crashes.

struct User {
    var index: Int
    var name: String
}

struct ContentView : View {
    var users: [User] = [
        User(index: 0, name: "Peter"),
        User(index: 1, name: "Marko"),
        User(index: 2, name: "John")]

    var body: some View {
        NavigationView {
            List(users.identified(by: \.index)) {
                UserRow(user: $0)
            }
            .navigationBarTitle(Text("Users"), displayMode: .inline)
        }
    }
}

struct UserRow: View {
    var user: User
    var body: some View {
        Text(user.name)
    }
}

我想这是一个SwiftUI错误.

I suppose that it is a SwiftUI bug.

有人知道可能是什么问题吗?预先感谢.

Does someone know what could be the problem? Thanks in advance.
