swift - Swift 错误：执行被中断原因：EXC_BREAKPOINT
问题描述
我重命名了一个文件。我的代码中没有出现错误，但尚未收到此消息。请帮忙！给出错误（不知道为什么堆栈要求我提供更多信息，但我已经尝试了所有方法来解决问题，例如，DerivedData，制作新的游乐场等）（不幸的是，我无法在此处输入我的整个代码，非常感谢帮助，因为我对 Swift 还比较陌生，我什至不知道 EXC_BREAKPROINT(code=1) 错误是什么，尽管谷歌搜索解决方案。）

解决方案
可以有两种方法来解决这个问题：重建你所有的行快捷方式来清理是这个：shift+command+K
正如您所说，您重命名了文件。您可以做的其他事情是将所有代码复制到具有您要求的名称的新文件中。如果您的代码很好，这应该可以工作，否则请分享代码。
