【问题描述】：

我的 macOS 应用程序编译并运行良好，但自从切换到 Xcode 11 后，我无法再从断点进行调试。调试器总是会因为一堆这样的消息而崩溃：

warning: Swift error in scratch context: /foobar/Foo-Bridging-Header.h:14:9: note: in file included from /foobar/Foo-Bridging-Header.h:14:
#import "TPPreciseTimer.h"
    ^

error: /foobar/Timer/TPPreciseTimer.h:9:9: error: 'Foundation/Foundation.h' file not found
#import <Foundation/Foundation.h>
    ^

/foobar/Timer/TPPreciseTimer.h:9:9: note: did not find header 'Foundation.h' in framework 'Foundation' (loaded from '/System/Library/Frameworks')
#import <Foundation/Foundation.h>
    ^

error: failed to import bridging header '/foobar/Foo-Bridging-Header.h'
.
Shared Swift state for Foo has developed fatal errors and is being discarded.
REPL definitions and persistent names/types will be lost.

Message from debugger: The LLDB RPC server has crashed. The crash log is located in ~/Library/Logs/DiagnosticReports and has a prefix 'lldb-rpc-server'. Please file a bug and attach the most recent crash log.

有人知道这样的解决方法吗？

我仍在使用 Xcode 10.3 的同事使用相同的代码库没有遇到此问题。

【问题讨论】：

它不再发生了。也许苹果解决了这个问题？

【参考方案1】：

这里也一样。删除 /Users/user/Library/Developer/Xcode/DerivedData 目录有所帮助。
