将数据从结构初始化传递到另一个视图控制器

// 源视图控制器
class SourceViewController: UIViewController {
    struct MyData {
        var name: String
        var age: Int
    }
    
    var data: MyData!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 初始化数据
        data = MyData(name: "John", age: 25)
    }
    
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "showDestination" {
            if let destinationVC = segue.destination as? DestinationViewController {
                // 将数据传递给目标视图控制器
                destinationVC.receivedData = data
            }
        }
    }
}

// 目标视图控制器
class DestinationViewController: UIViewController {
    struct MyData {
        var name: String
        var age: Int
    }
    
    var receivedData: MyData!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 使用传递的数据
        print("Name: \(receivedData.name)")
        print("Age: \(receivedData.age)")
    }
}
