正如标题中所说，3个@AppStorage变量中有2个在第一次没有更新。所以，当视图被关闭时，我必须重新打开它，然后在第二次关闭时，它们都被更新了。准确地说，第一次只有storedCityName被更新了。
这里的观点：

import SwiftUI

struct SearchView: View {
    @Environment(\.dismiss) private var dismiss
    @EnvironmentObject private var searchManager: SearchManager
    @AppStorage("storedUserLatitude") private var storedUserLatitude: Double?
    @AppStorage("storedUserLongitude") private var storedUserLongitude: Double?
    @AppStorage("storedCityName") private var storedCityName: String?

    var body: some View {
        VStack {
            TextField("", text: $searchManager.search)

            ForEach(searchManager.searchResults, id: \.self) { result in
                HStack {
                    VStack {
                        Text(result.title)
                        Text(result.subtitle)
                    }
                }
                .onTapGesture { update(result.title) }
            }
        }
    }

    private func update(_ city: String) {
        searchManager.searchLocation(city)
        storedUserLatitude = searchManager.userLocation?.coordinate.latitude
        storedUserLongitude = searchManager.userLocation?.coordinate.longitude
        storedCityName = city
        dismiss()
    }
}

字符串
这是经理：

import Foundation
import MapKit
import Combine

class SearchManager: NSObject, ObservableObject, MKLocalSearchCompleterDelegate {
    private let completer = MKLocalSearchCompleter()
    @Published var search = ""
    @Published var searchResults = [MKLocalSearchCompletion]()
    @Published var userLocation: CLLocation?
    private var publisher: AnyCancellable?

    override init() {
        super.init()
        completer.delegate = self
        completer.resultTypes = .address

        publisher = $search
            .receive(on: RunLoop.main)
            .sink(receiveValue: { string in
                self.completer.queryFragment = string
            })
    }

    func completerDidUpdateResults(_ completer: MKLocalSearchCompleter) {
        searchResults = completer.results
    }

    func searchLocation(_ city: String) {
        let geocoder = CLGeocoder()

        geocoder.geocodeAddressString(city) { placemarks, error in
            guard let placemark = placemarks?.first else { return }
            self.userLocation = placemark.location
        }
    }
}

型
我真的不明白为什么它在第二次尝试时有效，但在第一次尝试时无效。
我还尝试用DispatchQueue.main.asyncAfter(deadline: .now() + 2) { dismiss() }延迟dismiss，看看@AppStorage变量是否需要时间更新，但它没有改变任何东西。
你知道发生什么事了吗？
谢谢，提前！
