ios - @AppStorage 变量上的“调用初始化程序时没有完全匹配”错误？

Question

我收到以下错误:No exact matches in call to initializer在我的@AppStorage下面的变量:
模型.swift

class UserSettings: ObservableObject {
    @AppStorage("minAge") var minAge: Float = UserDefaults.standard.float(forKey: "minAge") 

此变量旨在绑定(bind)到 Slider值低于。
Settings.swift

import SwiftUI
struct Settings: View {
    let auth: UserAuth
    init(auth: UserAuth) {
        self.auth = auth
    }
    @State var minAge = UserSettings().minAge
    let settings = UserSettings()

    var body: some View {
            VStack {
                NavigationView {
                    Form {
                        Section {
                        Text("Min age")
                        Slider(value: $minAge, in: 18...99, step: 1, label: {Text("Label")})
                            .onReceive([self.minAge].publisher.first()) { (value) in
                                UserDefaults.standard.set(self.minAge, forKey: "minAge")
                            }
                        Text(String(Int(minAge)))
                        }

知道问题是什么吗？

Answer 1

我也看到以下相同的错误:

@AppStorage ("FavouriteBouquets") var favouriteBouquets: [String] = []()

AppStorage 可能不支持字符串数组。
