构建Xcode 8命令行工具模板需要哪些步骤？

Question

MacOS命令行工具的模板项目不能在XCode 8中为我构建。这是整个代码：

#import <Foundation/Foundation.h>

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        // insert code here...
        NSLog(@"Hello, World!");
    }
    return 0;
}

导入行发生故障。错误输出的开头如下所示。

我有一台运行El Capitan的新机器。我在一周前从GM下载（不是应用程序商店）安装了Xcode 8。

我需要做些什么来构建它？

错误输出：

Answer 1

在/Applications/

下安装Xcode

查看这些路径，Xcode直接从下载目录运行，在该目录中，它从GM种子xip文件中解压缩（即它在"/Users/ahcox/Downloads/Xcode.app/"中）。手动将其复制到/Applications/或运行App Store应用程序，让它在需要的地方安装Xcode。为了解决这个问题，我做了后者。 有关installation of apps on MacOS的更多信息。
