Question

我们已将iOS项目迁移到Swift 3和Xcode 8.从那时起，调试器无法显示任何变量值。如果我尝试打印变量：

p someVar

我收到此错误消息。 SchemaManager.h是一个桥接标题。（实际项目名称已被下面的yyy替换）：

warning: Swift error in module yyy.
Debug info from this module will be unavailable in the debugger.

error: in auto-import:

error: failed to import bridging header '/Users/xxx/Documents/yyy/yyy/Common/Model/Bridging-Header.h'

核心错误归结为：

error: 'utmp.h' file not found

我在其他地方读过，桥接标题中的问题可能会阻止调试器显示变量值。但我不确定如何解决这个问题。

TLDR;清理你的桥接头，确保你只有你需要的东西。

我遇到了同样的问题，但在failed to get module 'yyy' from AST context之后没有输出。我从桥接标题中删除了所有内容，然后逐个添加项目以确保我需要一切。

我发现在顶部添加#import <UIKit/UIKit.h>是必要的（但最初缺失）并找到了一些我不需要的东西，因为我改变了我的项目结构而忘记删除一些包含。毕竟，它开始工作。希望这会有所帮助。

Swift 3迁移后无法在调试器中查看变量值
