在 SwiftUI 中使用带有 @EnvironmentObject 的 ForEach(data:,content:) 而不求助于尾随闭包语法?

Using ForEach(data:,content:) with an @EnvironmentObject in SwiftUI without resorting to trailing closure syntax?

我正在重构我的代码,并希望使用 ForEach(data:,content:) 的成员初始化器。

我有一个 viewModel,其中包含符合 Identifiable 的结构数组:

class ViewModel: ObservableObject {
    @Published var int = 0
    
    var cellModels: [CellModel]
    
    init() {
        self.cellModels = [CellModel(id: 0, string: "Foo"),
                           CellModel(id: 1, string: "Bar")]
    }
}

struct CellModel: Identifiable {
    var id: Int
    var string: String
}

然后我创建了一个 CellView,它有一个来自 CellModel 的成员初始化程序,还有一个 EnvironmentalObject,它是 ViewModel 的一个实例:

struct CellView: View {
    @EnvironmentObject var environment: ViewModel
    var cellModel: CellModel
    var body: some View {
        Text(cellModel.string)
    }
}

但是,当我创建父视图时,在 ForEach(data:, content:) 行出现编译器错误:

struct DemoView: View {
    @StateObject var viewModel = ViewModel()
    var body: some View {
        VStack {
            ForEach(viewModel.cellModels, content: CellView.init) // Compiler error is here
// Cannot convert value of type '(EnvironmentObject<ViewModel>, CellModel) -> CellView' to expected argument type '(CellModel) -> CellView'
        }
        .environmentObject(viewModel)
    }
}

我知道这是因为 ForEach(data:,content:) 试图将 EnvironmentObject 和单独的模型传递给每个 CellView,但是有没有办法做到这一点 without 必须使用带有尾随闭包的 ForEach(data:,content:)? :

ForEach(viewModel.cellModels){ cellModel in
                CellView(cellModel: cellModel)
            }

将 init 与 without argumentLabel

一起使用
struct CellView: View {
    @EnvironmentObject var environment: ViewModel

    private var cellModel: CellModel

    init(_ cellModel: CellModel) {
        self.cellModel = cellModel
    }

    var body: some View {
        Text(cellModel.string)
    }
}

struct DemoView: View {
    @StateObject var viewModel = ViewModel()
    var body: some View {
        VStack {
            ForEach(viewModel.cellModels, content: CellView.init)
        }
        .environmentObject(viewModel)
    }
}
