ios – 在Swift 3迁移后无法在调试器中查看变量值

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是一个桥接头. (实际的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:
failed to get module 'yyy' from AST context:

核心错误归结为：

error: 'utmp.h' file not found

我在其他地方读过,桥接头中的问题可以阻止调试器显示变量值.但我不确定如何解决这个问题.

解决方法

TLDR;清理你的桥接头,确保你只有你需要的.

我遇到了同样的问题,但是在AST上下文中无法获得模块’yyy’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.

我发现添加#import< UIKit / UIKit.h>在顶部是必要的(但最初缺少)并找到一些我不需要的,因为我改变了我的项目结构,忘了删除一些包含.毕竟,它开始工作.希望这会有所帮助.
