当编译器对代码中发生的事情感到困惑时,您可能会收到此错误.我注意到你有很多看似嵌套在函数中的函数.您可以尝试一次评论其中一些,以查看错误是否消失.这样你就可以把问题区域归零.您不能使用断点,因为它是编译时错误,而不是运行时错误.

  • @ParanoidAndroid你能详细说明问题是什么吗？我也遇到了这个问题 (3认同)

我最近遇到了同样的问题,我将尝试概括我是如何解决它的,因为很多这些答案都是为了帮助每个人.

1.首先查看错误消息的底部,以识别导致分段错误的文件和功能.

错误信息

2.然后,我看那个函数和注释掉了这一切.我编译了它现在工作了.然后我一次从函数的某些部分删除了注释,直到我找到了导致错误的行.在此之后,我能够修复它,一切正常.:)

  • 最后几行给出了最好的提示.这个答案帮了很多忙! (2认同)

对于遇到此问题的其他人...我发现问题是由导入自定义框架引起的,我不知道如何纠正它.但是,只需从框架中删除导入和引用项目的任何代码即可解决问题.

希望这可以拯救某人几个小时追逐哪条线导致问题.

  • 在更新到Xcode 7.3时,Eureka也是我的情况.更改为v1.5并进行了pod安装,然后一切都很顺利. (3认同)

对我来说,这是由Swift 2.0中Parse SDK语法的变化引起的.如果您正在使用Parse并升级到Swift 2.0,则以下语法会更改:

Swift 1.2:

myPFQuery.findObjectsInBackgroundWithBlock({ (queryResults: [AnyObject]?, error: NSError?) -> Void in

    // CODE

})

Swift 2.0:

myPFQuery.findObjectsInBackgroundWithBlock { (queryResults: [PFObject]?, error: NSError?) -> Void in

    // CODE

}

删除第一个'('和最后')'是导致最大问题的原因.花了我一把才发现这个!

Wil*_* T. 7

当我从Swift转换为Swift 2.0时出现此错误时,它清楚地表明存在问题的特定文件(blahClass.swift),然后它概述了错误消息文本中的所有警告和错误.我经历了手动解决这些问题,现在应用程序编译得很好.

  • 在这里添加另一个数据点.我在Swift 2迁移过程中也遇到了这个错误.我最终打开了它失败的文件并注释掉了大部分代码.该应用程序然后编译,我能够一次取消注释几行代码来追踪问题. (3认同)

我遇到了这个错误.经过一番挫折之后,我尝试了Xcode干净,一切都开始了.把这个留在这里以备将来参考.

我在回滚每个步骤后找到了原因....强制转换为Int为Double变量

n13*_*n13 6

对我来说,这是由我的一些代码引起的.XCode中详细的编译器输出实际上指出了它崩溃的方法.

然后我注释掉了方法中的所有代码,使它返回nil,并且它确实编译了.然后我使用不同且更简单的代码重新实现了该方法,并且它起作用了.

我向Apple提交了一份错误报告.这是 - 无可否认有点疯狂 - 导致XCode 7/Swift 2.0崩溃的代码.

  func numberAndTitleFromDirectoryName(dirName: String) -> (Int, String)? {
    let components = dirName.characters.split(maxSplit: 1, allowEmptySlices: false) { $0 == " " }.map { String($0) }.map { String($0) }
    if let number = components.first?.toInt() {
        if let title = components.last {
            return (number, title)
        }
    }
    return nil;
  }

我想我在那里使用地图功能有点过于兴奋......新版本更简单,更易于理解.仍然编译器不应该崩溃.在最坏的情况下,它应该显示一些错 代码在Swift 1.x中工作
