我参考了该文章 https://juejin.cn/post/7025992880464330766 ，已经关闭了 SIP ，在 iOS simulator 上可以正常使用 Xcode 来 attach 其他应用（如 Maps.app 等），但是在真机上 attach 其他应用时却总是报错（测试了许多不同的第三方应用），如图所示：
> Could not attach to pid: “34569”
> attach failed (Not allowed to attach to process. Look in the console messages (Console.app), near the debugserver entries, when the attach failed. The subsystem that denied the attach permission will likely have logged an informative message about why it was denied.)
在 Console.app 中，搜索 debugserver 得到的记录是：
```

```
我在网上参考了其他网页，已经设置了`sudo DevToolsSecurity -enable`，检查了`get-task-allow`在我的应用中已经设为`true`，甚至是抹掉了 iPhone ，但是依然没有解决问题。
不知有没有 iOS 开发大佬遇到类似的问题，能够提供解决方案的。
我测试的 Xcode 版本为 14.3.1 (14E300c)和 15.0 beta 2 (15A5161b)，macOS 版本为 13.4.1 （ Intel 处理器），真机试了两台，iOS 版本分别为 16.5 和 17.0 beta 2 ，均出现上述问题。
莫非这个 feature 是必须加入 Developer Program 才可以使用吗，或是 Apple 芯片专用？
