如何修复"Xcode在使用libclang.dylib插件时意外退出."？

Question

我在启动xCode(5.1.1)之后的每一次都有这个.

删除用户数据,关闭源代码控制(如某些帖子建议),没有效果,仍然崩溃(同时显示索引......永远不会完成).即使重新安装 xCode,没有任何影响,仍然说同样的.

有人修过这样的xCode吗？

Answer 1

声明中有一个.m文件#import!

它是由一行代码引起的!不能相信它.偷了4个小时搞清楚.哦,它是由一份@class声明合并而成的.

它显示为错误,但xCode/Clang崩溃的速度甚至超过了你甚至可以构建的速度.:d

致命的模式:

One.h

#import "Two.m" // Not easy to spot actually.

@interface One : NSObject
@end

Two.h

@class One;
@interface Two : NSObject
@property (nonatomic, weak) One *one;
@end

除非我提到超过200个课程的项目,否则我无法重现它.那一定是某种竞争条件.
