swift - 如何修复 Swift 编译问题 trap6

Question

问题发生在 Swift3 和 XCode10。这可能是一个 Swift 错误。实际上，clean 和 rebuild 可以解决问题，但是那太浪费时间了。任何人都知道解决或避免问题的有效方法。谢谢

error: Abort trap: 6  

Answer 1

这是一个 Swift 编译器错误。您可能通过链接由不同版本的编译器编译的模块或其他一些不受支持的行为来触发它，但它可能仍然不应该崩溃。

但是，您说这是 Swift 3 的问题。 Swift 开发人员不再支持 Swift 3。他们正在研究 Swift 5。如果您可以在 Swift 5 中重现该问题，您可以在 https://bugs.swift.org 提交错误报告。 .
