ios - deserialization failure with swift4.2 (xcode10) Abort trap: 6

问题描述

I tried to transfer swift 4 to swift 4.2 with XCode 10.0 release then got this msg:

*** DESERIALIZATION FAILURE (please include this section in any bug report) ***

and this in the end:

1.  While deserializing SIL vtable for 'MenuNavTitleView' in module 'projectName'
error: Abort trap: 6

I looked for some reasons such as .zero, then even I replaced all .zero in my code, it still have this problem.

Does someone know how to fix this fatal error?

解决方案

我在 Xcode 10.2.1 中遇到了同样的问题。

经过几天的尝试解决它，我发现在我的情况下，这个错误是由一个继承了 Objective-C 第三方类的 Swift 类引起的（更具体地说是FSCalendarCell来自https://github.com/WenchaoD/FSCalendar的类）。

我为 Objective-C 重写了 Swift 类，它编译并运行没有任何问题。
