如何访问Swift中的深度嵌套对象

struct OuterObject {
    var innerObject: InnerObject?
}

struct InnerObject {
    var nestedObject: NestedObject?
}

struct NestedObject {
    var value: Int
}

let outer = OuterObject(innerObject: InnerObject(nestedObject: NestedObject(value: 10)))

let nestedValue = outer.innerObject?.nestedObject?.value

if let value = outer.innerObject?.nestedObject?.value {
    // 可选值存在，进行进一步的操作
    print(value)
} else {
    // 可选值不存在
    print("无法访问嵌套对象")
}
