xcode - 命令 ...swiftc 失败，退出代码为 1

Question

我被这个错误困扰了一段时间，而且我发现的解决方案似乎都不起作用(至少，对我来说是这样)。这是完整的错误日志:

我尝试过的:

• 清理项目

• 评论我最后的修改

• 创建一个新项目并传输代码

当我创建一个新项目时，这个错误消失了，但是另一个错误说有一个到 main 的隐式入口点。在整个项目中搜索主要功能，但没有任何结果。我的整个代码是 here ，如果它有任何用处的话。

Answer 1

尝试使用xcodebuild -project ***.xcodeproj -scheme ***，它会给你更多关于错误的细节。

对我来说，将 [unowned self] 添加到 block 中的 block 中。
