如何将状态变量作为参数传递给ObservableObject类型的模型类？

Question

我想将一些数据从SwiftUI视图保存到模型，以便可以将这些数据用于另一个SwiftUI视图。但是，当我尝试调用Model类并将所有数据作为参数传递时，出现了一些错误。错误提示：

不能在属性初始化程序中使用实例成员'expectedEndDate'；属性初始值设定项在“自我”可用之前运行”

这是我的SearchBikeDataModel（）代码：

import Foundation

class SearchBikeDataModel: ObservableObject {
    @Published var startDate: Date = Date()
    @Published var startTime: Date = Date()
    @Published var endDate: Date = Date()
    @Published var endTime: Date = Date()

    @Published var bikeType: String = ""
    @Published var collectionPoint: String = ""
    @Published var returnPoint: String = ""

    init(selectedStartDate: Date, selectedStartTime: Date, selectedEndDate: Date, selectedEndTime: Date, bikeType: String, collectionPoint: String, returnPoint: String) {
        self.startDate = selectedStartDate
        self.startTime = selectedStartTime
        self.endDate = selectedEndDate
        self.endTime = selectedEndTime

        self.bikeType = bikeType
        self.collectionPoint = collectionPoint
        self.returnPoint = returnPoint
    }
}

这是我尝试将数据作为参数传递的代码：

import SwiftUI

struct BikeSearchFormView: View {
    @Binding var isDateTimeShown: Bool
    @Binding var isEndDateTimePickerShown: Bool

    @State var expectedStartDate = Date()
    @State var expectedStartTime = Date()
    @State var expectedEndDate = Date()
    @State var expectedEndTime = Date()

    @State var isBikeTypePickerExpand: Bool = false
    @State var isDropOffPointPickerExpand: Bool = false
    @State var isPickUpPointPickerExpand: Bool = false

    @State var selectedBikeType: String = "BIKE TYPE"
    @State var selectedDropOffPoint: String = "DROP OFF POINT"
    @State var selectedPickUpPoint: String = "PICKUP POINT"

    @State var findBikeError: String = ""
    @State var isActive: Bool = false

    @ObservedObject var bikeTypeViewModel = VehicleTypeViewModel()
    @ObservedObject var findBikeViewModel = FindBikeViewModel()

    @ObservedObject var dataModel = SearchBikeDataModel(selectedStartDate: expectedStartDate, selectedStartTime: expectedStartTime, selectedEndDate: expectedEndDate, selectedEndTime: expectedEndTime, bikeType: selectedBikeType, collectionPoint: selectedPickUpPoint, returnPoint: selectedDropOffPoint)

var body: some View {
    Text("Hello, World")
}
}

我已经省略了UI代码，因为问题在于我是否遵循正确的方法将数据传递给参数。
