ios - Swift:Apple Mach-O 链接器错误(文件对于架构 x86_64 而言太小)

Question

我正在创建一个从网站获取信息的天气应用程序。上次我编码时(昨晚)一切都很好，我能够毫无错误地编译和运行模拟器。就在今天，当我启动同一个项目时，没有做任何更改，我收到了“Apple Mach-O Linker Error”。请大家帮忙解决一下好吗？

错误详情如下:

在底部:

ld: file too small (length=0) file '/Users/Allister/Library/Developer/Xcode/DerivedData/Haze_Meter-dkjjcmjehyitmcbhkcbujnsrhwpu/Build/Intermediates/Haze Meter.build/Debug-iphonesimulator/Haze Meter.build/Objects-normal/x86_64/ViewController.o' for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我在 StackOverflow 上检查了其他“Apple Mach-O Linker Error”，但它们似乎与我有不同的“ld”，尽管是相同的“clang”。

Answer 1

尝试完全重建/清理。之前的构建可能已异常中止，导致 ViewController.o 文件损坏或大小为零。

要清理:在 Xcode“产品”菜单中，选择“清理”(快捷键:Cmd+Shift+K)

要重建:在 Xcode“产品”菜单中，选择“构建”(快捷键:Cmd+B)

如果不起作用:在 Xcode“产品”菜单中，按住 Option 键，然后选择“清理构建文件夹”
