Xcode 9编译的应用程序和iOS 9.5.3（iPad 2）
[英]Xcode 9 compiled app and iOS 9.5.3 (iPad 2)
问题描述
Anyone noticed issues with apps that are created with Xcode 9 and do not seem to work on iOS 9.5.3 and in this case an older iPad 2? 
有人注意到使用Xcode 9创建的应用程序出现问题，但似乎无法在iOS 9.5.3上运行，在这种情况下，这是一个较旧的iPad 2？
I have a customer that downloaded my app that I've complied and uploaded with Xcode 9, but when he installs the app it crashes straight away, and on some occasions in a flash of 2 sec. 我有一个客户下载了我已经编译并使用Xcode 9上传的应用程序，但是当他安装该应用程序时，该应用程序立即崩溃，有时甚至需要2秒的时间。 will display the interface builder screen layout of the app (ie all the views, buttons etc that are visible on interface builder but with a normal app nicely hidden until needed etc). 将显示该应用程序的界面构建器屏幕布局（即，在界面构建器上可见的所有视图，按钮等，但在需要之前隐藏了一个普通应用程序等）。
The minimum development target in Xcode is set to 8.2 so I assume it will and should be backwards compatible? Xcode中的最低开发目标设置为8.2，因此我认为它将并且应该向后兼容？

Seems like the device is jailbroken.. My latest app version includes a check for a jailbroken device, and does not allow the app to load when it detects one. 好像该设备已越狱。。我最新的应用程序版本包括对越狱设备的检查，并且不允许该应用程序在检测到该设备时加载。 I Could reproduce the exact behaviour when triggering this validation check. 触发此验证检查时，我可以重现确切的行为。
