如何在SwiftUI中使用动态本地化密钥

import SwiftUI

// 创建本地化管理器
class LocalizationManager: ObservableObject {
    @Published var currentLanguage = "en" // 当前语言，默认为英语
    let localizations = [
        "en": ["welcome": "Welcome", "hello": "Hello"],
        "zh-Hans": ["welcome": "欢迎", "hello": "你好"]
    ] // 本地化密钥值
    
    // 根据当前语言获取密钥值
    func localizedString(forKey key: String) -> String {
        guard let localizedStrings = localizations[currentLanguage] else {
            return ""
        }
        return localizedStrings[key] ?? ""
    }
}

struct ContentView: View {
    @ObservedObject var localizationManager = LocalizationManager()
    
    var body: some View {
        VStack {
            Text(localizationManager.localizedString(forKey: "welcome"))
            Text(localizationManager.localizedString(forKey: "hello"))
        }
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
