Xcode给出了以下代码的错误消息“Ambiguity use of 'Preview'”：

import SwiftUI

struct TileDetailView: View {
    @Binding var tile: Tile  // This is a custom object
    @Binding var isShowingTileDetail: Bool
    
    var body: some View {
        Text("This is a tile.")
    }
}

#Preview {
    let bindingVar = Binding.constant(false)
    let aTile = AMClass(name: "A Tile")
    let bindingTile = Binding<Tile>(
        get: { aTile }
    )
    return TileDetailView(aTile: bindingTile, isShowingClassDetail: bindingVar)
}

请随时指出上述代码的问题。谢谢。
