libc++abi.dylib: terminating with uncaught exception of type NSException

在XCode11.3.1 11.3 11.2.1 均报错如下

Trapped uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named _UIScrollerImpContainerView because no class named _UIScrollerImpContainerView was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)'

官网也没有解决方案. 近年Apple的开发一直被吐槽Bug太多. 顶不住了.
看上下文描述. 似乎是用到xib启动的时候出问题. 找不到_UIScrollerImpContainerView这个系统Class.
坑爹.

最后解决方案是下载老版本 Xcode 11.1 打包解决. 或等新版本Xcode解决后更新.
