如何从结果json表中生成全局变量？:SwiftUI

struct ContentView: View {
    @State private var jsonData: [String: Any] = [:]
    
    var body: some View {
        // 视图内容
    }
}

struct ContentView: View {
    @State private var jsonData: [String: Any] = [:]
    
    var body: some View {
        // 视图内容
    }
    
    func fetchData() {
        guard let url = URL(string: "https://example.com/api/data") else { return }
        
        URLSession.shared.dataTask(with: url) { (data, response, error) in
            guard let data = data else { return }
            
            do {
                let json = try JSONSerialization.jsonObject(with: data, options: [])
                if let jsonDict = json as? [String: Any] {
                    DispatchQueue.main.async {
                        self.jsonData = jsonDict
                    }
                }
            } catch {
                print("Error: \(error)")
            }
        }.resume()
    }
    
    // 在视图出现时调用fetchData方法
    .onAppear(perform: fetchData)
}

struct ContentView: View {
    @State private var jsonData: [String: Any] = [:]
    
    var body: some View {
        VStack {
            Text("Name: \(jsonData["name"] as? String ?? "")")
            Text("Age: \(jsonData["age"] as? Int ?? 0)")
        }
    }
}
